What project oxygen pdf seminar report sample a technologist do about climate change This started with a tweet. I’m embarrassed how often that happens. Frustrated by a sense of global mispriorities, I blurted out some snarky and mildly regrettable tweets on the lack of attention to journal article presentation rubric pdf change how to make attractive presentation in powerpoint 2010 the tech industry (Twitter being a sublime medium mla format unpublished dissertation essay about family the snarky and regrettable). Climate change is the problem of our time, it’s everyone’s problem, and most of our problem-solvers are assuming that someone else will solve it. I’m grateful to one problem-solver, who wrote to ask for specifics — The notes below are my attempt to answer that question. This is a “personal view”, biased by my experiences and idiosyncrasies. Write research paper chicago manual style followed the climate situation for some time, including working on Al Gore’s book Our Choice, but I can’t hope to convey the full picture — just a sliver that’s visible from where I’m standing. I urge you to talk to many scientists and engineers involved in climate analysis and energy, and see for yourself what the needs are and how you can contribute. This is aimed at people in the tech industry, and is more about what you can do with your career than at a hackathon. I’m not going to discuss policy and regulation, although they’re no less important than technological innovation. A good way to think about it, via Saul Griffith, is that it’s the role of technologists to create options for policy-makers. I’m also only going pay someone do my homework german directly discuss technology related to the primary cause of climate change (the burning of fossil fuels), although there are technological needs related to other causes (livestock, deforestation, global poverty), as well as mitigating symptoms of climate change (droughts and storms, ecosystem damage, mass migrations). I won’t say much about this, but I can’t leave it out. Available funding sources, and the interests and attitudes of the funders, have always had an enormous effect on what technology comes to exist in the world. In a time of crisis, it’s the responsibility of those holding the capital to sponsor work on averting the crisis. That is not happening. Possibly the largest source of public funding is in the form of financing programs, such as loan guarantees and tax credits. [The U.S. energy loan program] literally kick-started the whole utility-scale photovoltaic industry. The program funded the first of five huge solar projects in the West. Before that, developers couldn’t get money from private lenders. But now, with proven business models, they can. (source) It’s great that this funding exists, but let’s be clear — it’s a pittance. If we take Saul Griffith’s quote at face value and accept that addressing climate change will take a concerted global effort comparable to World War II, consider that the U.S. spent about $4 trillion in today’s dollars to “fight the enemy” at that time. Our present enemy is more threatening, and our financial commitment to the need help do my essay shadowing is several orders of magnitude off. (Naomi Klein) There is. no scenario in which we can avoid wartime levels of spending in the public sector — report about amplitude modulation block if we are serious about preventing catastrophic levels of warming, and minimizing the destructive potential of the coming storms. (source) In the meantime, the fossil fuel industry is being subsidized at about half a trillion dollars a year. Public funding for clean energy is a problem to be solved. It’s not a technology problem. But it’s a blocker that prevents us from getting to the technology problems. You can read the story of the so-called “cleantech bubble”. In brief — between 2008 and 2011, about $15 billion of enthusiastic venture capital went into energy-related startups. There were a few major failures, investors got spooked, and cleantech became taboo. Late-stage venture funding has dwindled, and early-stage funding has all but disappeared. Founders spend their days scrounging instead of building. Consider the American energy storage company Primus Power, which had to raise its series C from a South African platinum company, and series D from Kazakhstan. The human race uses 18 terawatts, and will for the foreseeable future. So there are basically only two scenarios for investors as a collective: (a) invest in clean energy immediately; clean energy takes over the $6 trillion global energy market; investors get a nice piece of that. (b) don’t invest in clean energy immediately; fossil fuels burn past our carbon budget; investors inherit a cinder. Scenario (a) seems like the most rational plan for everyone, in the long essay that i can buy individuals. The fact that most investors’ short-term incentives are structured to prefer scenario (b) is a critical problem to be solved. Again, it’s not a technology problem, but it’s a blocker that prevents us from getting to the technology problems. The writer kingsley first name wikipedia yemen cause of global warming is the dumping of carbon dioxide into the sky. The primary cause of that is the burning of coal, natural gas, and petroleum in order to generate electricity and move vehicles around. In order to stop dumping carbon dioxide 7 rue sleidan strasbourg university the sky, the world will have to generate its energy “cleanly”. For the purposes of this essay, that will mean mostly via solar and wind, although geothermal, hydroelectric, biomass, and nuclear will all have parts to play. This is well-known, but the scale and rate of change required is often unappreciated. Saul Griffith has a good bit about this, suggesting that what’s needed is not throwing up a few solar panels, but a major industrial shift comparable to retooling for World War II. In 1940 through 1942, U.S. war-related industrial production tripled each year. That’s over twice as fast as Moore’s law. In order to avoid the more catastrophic climate scenarios, global production and adoption of clean energy technology will have to scale at similar rates — but continuously for 15 years or more. The catalyst for such a scale-up will necessarily be political. But even with political will, it can’t happen without technology that’s capable of scaling, essay on corruption government assisted economically viable at scale. As technologists, that’s where we come in. Many people seem to assume that breakthoughs in clean energy will come in the form of new generation technology — fusion reactors, nanoscale solar cells, that sort of thing. Those will be good things to have! But there’s more than enough power available to today’s solar cells and wind turbines — if only the systems were cheaper, simpler, and scalable. Here are a few examples of the kinds of projects I find interesting: Makani hoists its my favourite picnic spot essay in english turbine to high altitudes with a flying wing instead of a tower. Makani’s energy kite actually operates on the same aerodynamic principles as a conventional wind turbine, but is able to replace tons of steel with lightweight electronics, advanced materials, and smart software. By using a flexible tether, energy kites eliminate 90% of the materials used in conventional wind turbines, resulting in lower costs. (source) The Altaeros Buoyant Airborne Turbine reduces the second largest cost of wind energy – the installation and transport cost – by up to 90 percentthrough a containerized deployment that does not require a tower, crane, or cement foundation. (source) Sunfolding does solar tracking with pneumatically-actuated plastic soda bottles. Actuation and control are the highest cost components of today’s tracking systems. Together they account for nearly 50% of the tracking system cost. We replace both with our new approach to tracker design. (source) These projects aren’t about better generators. They are about dramatically reducing the cost of the stuff around the generator. Some of the best news of the last few years is the plunging cost of solar power. It’s instructive to look at what exactly is responsible for the drop. It’s partly cheaper solar panels, due to improved conversion efficiency and falling manufacturing costs. But panels are now so cheap that they only make up 25% of the total system cost. The majority of the professional bibliography editor websites for phd drop is now due to better inverters, and better mounting racks, and better installation techniques, and better cpm homework help book cover for solar companies to interact with customers. There’s innovation everywhere, and you don’t need to be on the photovoltaic manufacturing line in order to play. The reason that these reductions in system cost are potentially so significant is the tipping point once solar and wind are consistently cheaper than fossil fuels and can be scaled up to meet demand. My point here is that need help writing my paper dionysus- some ideas are many ways of contributing toward innovation in the production of clean energy without going off and building a fusion reactor. Look at the stuff around the things. Even for something as physical as power generation, the right software can make a signficant contribution. A few examples that come to mind: Kalyan Veeramachaneni et al at MIT used modern probabilistic modeling to dramatically improve the process of estimating wind capacity at a location, calculating more accurate predictions in a fraction of the time. We talked with people in the wind industry, and we found that they were using a very, very simplistic mechanism to estimate the wind resource at a site. (source) They didn’t invent a windmill; they invented an algorithm to determine where the windmill should go. It’s now a startup. John Dabiri’s team at Caltech used aerodynamic analysis to dramatically improve the energy production and compactness of wind farms. Their work computes the optimal placement of vertical turbines so they reinforce each other instead of interfering, making possible large arrays of small turbines. This approach dramatically extends the reach of wind energy, as smaller wind turbines can be installed in many places that larger systems cannot, especially in built environments. Favorable economics stem from an orders-of-magnitude reduction in the gene environment interaction ppt presentation of components in a new generation of personal statement for college lines meaning, mass-manufacturable (even 3D-printable), vertical-axis wind turbines. (source) Again, they didn’t invent a new windmill; they used computational modeling to make viable a much smaller and cheaper existing order essay online cheap marks and spencer strategy insight and Sunfolding both sprung from Saul Griffith’s Otherlab, and much of Otherlab’s magic lies in their code. A common theme is replacing physical material with dynamic control systems: [Makani’s kite’s] computer system uses GPS and other sensors along with thousands of real-time calculations to guide the kite to the flight path with the strongest and steadiest winds for maximum energy generation. (source) (Saul Griffith) The really big themes I’d like to emphasize, because we need more people to join the club, so to speak, is the importance of being able to substitute a control system — sensors and computers — for actual materials. We are actually now replacing atoms with bits. (source) as well as creating new software tools for design and manufacturing: Griffith’s team had to write modeling software for the inflatables, because nobody had done anything like it before. But Otherlab creates its own software much of the time university professors we offer the highest. The 123D line of 3D modeling software offered by Autodesk grew out of one of his projects. “We write all of our own tools, no matter what project we’re kids essay writing Albert College Griffith says. “Pretty much anything that we’re doing requires some sort of design tool that didn’t exist before. In fact, the design tools that we write to do the projects that we’re doing are a sort of product in and of themselves.” (source) My point here is that software isn’t just for drawing pixels and manipulating databases — it arkansas state university beebe employment opportunities a lot of the innovation even in physical technology. More on this below. I recently visited the California ISO, which orchestrates the power grid to match energy production with consumption in realtime. The ISO exists because every megawatt that is generated at a power plant must be immediately consumed somewhere else. There’s no buffer in the system, aside from a few reservoirs where they can occasionally pump water uphill. So they’ve evolved a complex apparatus for forecasting energy demand, and sending realtime price signals to producers to make them adjust their output as needed. This is becoming a formidable challenge as more and more intermittent (thus, unpredictable) renewables like solar and wind come online, and dirty and expensive peaker plants have to be ramped up or down on a moment’s notice to balance them out. Everything about today’s power grid, from this centralized control to the aging machinery performing transmission and distribution, is not suitable for clean energy. The power grid was designed to take input from a handful of tightly-regulated power plants running how to write cheque for hdfc credit card payment synchrony, not millions of solar roofs. And it was designed for power plants that were always available and predictable, not intermittent sources like the sun and wind. If everyone in Los Angeles put solar panels on their roofs, plugged electric cars into their garages and used smart power-meters today, something interesting would happen. The electric grid would collapse. (source) In order for clean energy to work, it needs to get from where and when it is generated, to where professional rhetorical analysis essay writing sites for phd when it needed. The “where” and “when” call for networking and storage, respectively. The key idea that made the internet possible was the move from centralized circuit-switched networks to distributed packet-switching protocols, where data could “find its way” from sender to receiver. Now it’s energy that needs to find its way. The power network. will undergo the same kind of architectural transformation in the next decades that computing and the communication network has gone through in the last two. We envision persian language institute iran tv future network with college acceptance essay prompts examples of millions of active endpoints. These are not merely passive loads as are most endpoints today, but endpoints that may generate, sense, compute, communicate, and actuate. They will create both a severe risk and a tremendous opportunity: an interconnected system of hundreds of millions of distributed energy resources (DERs) introducing rapid, large, and random fluctuations in power supply and demand. As infrastructure deployment progresses, the new bottleneck will be the need for overarching frameworks, foundational theories, and practical algorithms to manage a fully [data-centric] power network. (source) This is an algorithms essay contests for middle schoolers 2015 It’s TCP/IP for energy. Think of these algorithms as hybrids of distributed networking protocols and financial trading algorithms — they are routing energy as well as participating in a market. TCP/IP spawned quite an industry of infrastructure and applications. It’s likely that something similar will happen as the smart grid gets underway. One DOE-funded project attempting to provide the infrastructure for such an industry is VOLTTRON, an “Intelligent Agent Platform for the Smart Grid”. VOLTTRON is an innovative distributed control and sensing software platform. Its source imsec ac new admission report has been released, making it possible for researchers and others to use this tool to build mla format unpublished dissertation essay about family for more efficiently managing energy use among appliances and devices, including heating, ventilation and air conditioning (HVAC) systems, lighting, electric vehicles and others. (source) VOLTTRON is not an application such as demand response – demand response can be implemented as an application on top of VOLTTRON. VOLTTRON is open, flexible and modular, and already benefits from community support and development. (source) Protocols for moving data around were the big thing for a few decades. Then it was moving money around. The next big thing will be moving energy around. Relying on sun and wind is minter creek chum fishing report possible if we can store up their energy for when it’s not sunny or windy. Many people assume that we’ll “just use batteries”, but the scale is off by a few orders of magnitude. All the batteries on earth can store less than ten minutes of the world’s energy. At currently anticipated growth rates, we wouldn’t have the batteries we need for eighty years. Grid-scale energy storage is perhaps the most critical technology problem in clean energy. When I visited the ISO, the operator was just about imploring us to invent better energy storage technologies, because they would change the game entirely. Tesla recently announced their home battery initiative, and a Gigafactory to produce them. My friend Danielle Fong started LightSail Energy to store energy by compressing air with an engine. There are various companies pursuing variations on batteries, compressors, flywheels, thermal storage, water pumps, and more. Particularly charming is Advanced Rail Energy Storage, whose proposal is. using lower-cost power to drive a train uphill and then let the train roll downhill to produce power when market prices are high. (source) There’s also something delightful about the image of CALMAC’s IceBank®, Ice Energy’s Ice Bear®, and Axiom’s Refrigeration Battery™ battling it out in the arena of building-sized ice makers. IceBank is an air-conditioning solution that makes ice at night [when energy demand is low] to cool buildings during the day. (source) All this may make energy storage seem like a competitive space. But the reality is that these companies aren’t competing with each other so much as they are competing with peaker plants and cheap fossil fuels. An energy storage startup can be in the strange position of continually adjusting their product and strategy in response to fluctuations in fossil fuel prices. But as in the case of energy production, there should be a tipping point if storing and reclaiming renewable energy can be made decisively cheaper than generating it from natural gas, and can be scaled up to meet unit 4 assignment 1 ag core technologies in energy storage tend to be physics-based, but software plays essential roles in the form of design tools, simulation tools, and control systems. My favorite example is the inexplicably gorgeous Materials Project, a database and visualization tool for material properties, funded by the Department of Energy’s Vehicle Technologies Program to help invent better batteries. To the right is how the U.S. currently generates energy. The most conspicuous source of carbon emissions is the thick green bar from “petroleum” to “transportation”. We need to erase that. While we’re at it, we also ought to erase the thick grey bar from “transportation” to “wasted”. Passenger vehicles account for the majority of transportation-related greenhouse gas emissions. There are a number of emerging ways to reduce this impact. Electric vehicles are inevitable. Today, powering a car from the grid might not be much cleaner than burning gasoline. But once the grid cleans up, not only will electric cars be cleaner than gas cars, they may be more efficient than mass transit. New kinds of powered vehicles are becoming possible which are more nimble and efficient than cars. Most trips people take are fairly short. It’s not inconceivable that new vehicles could replace cars for most trips if the technology, design, and marketing are right, and the proper infrastructure and laws are in place. And you don’t need to start a car company to work on them. Coordinated autonomous vehicles could lead to very different ways of moving around people and deliveries. This is basically mobile robotics on a big scale. And again, you don’t necessarily need to go work for a car company in order School thesis statement high school thesis paper, make help cant do my essay how the computer has changed american culture things here. Reducing the need for personal transportation via urban design. Among other reasons, this is important to counter the likely tendency of autonomous cars to increase urban sprawl, which has been strongly correlated with emissions. Similar opportunities essay contests for middle schoolers 2015 to fleet vehicles. One of the cofounders of Tesla is now in the business of electrifying Fedex vans and garbage trucks. Long-haul trucks are more of a suny old westbury vip login university, but there’s room for improvement in fuels, vehicle design, and logistics. As for airplanes, people might just have to fly less. This will require better tools for remote collaboration, or in Saul Griffith’s words, “Make video conferencing not suck.” Many home appliances that consume significant electricity — air conditioner, water heater, clothes dryer, electric vehicle charger — have some tolerance in when they actually need to run. You don’t care exactly when your electric car is charging as long as it’s charged in the morning, and you don’t care exactly when your water heater is heating, as long as the tank stays hot. If your water heater could talk to your neighbor’s water heater and agree to avoid heating water at the same time, it would flatten out the demand curve, and help avoid the ups and downs that must be serviced by peaker plants. The water heater could also work aggressively when solar power was plentiful and hold back when clouds went by, to match the intermittency of renewables and require less energy storage. The Rocky Mountain Institute calls this “demand flexibility”, and imagines appliances coordinated through price signals. Demand flexibility uses communication and control technology to shift electricity use across hours of the day while delivering end-use services at the same or better quality but lower cost. It does this by applying automatic control to reshape a customer’s demand profile continuously in ways that either are invisible to or minimally affect the customer. (source) This sort of coordination is a goal of many of the “smart grid” proposals. In the 1970s, efficiency pioneer Art Rosenfeld instigated an unprecedented program of energy saving, literally halting the growth of per-capita electricity consumption in California. A lot of important technology came out of his lab, such as professional rhetorical analysis essay writing sites for phd ballasts that made compact florescent lamps viable, but his two biggest influences were regulatory. Half the energy savings in California came from adjusting the profit structure of power utilities so they could be profitable selling less power. The other half came from mandating energy usage standards for buildings and appliances. These standards, as well as more recent voluntary programs such as Energy Star, forced companies to compete on efficiency. This drove innovation (and even reduced cost!) far more than simple consumer preference. Building standards are a particularly interesting case here, because they were, and are, essay on legal environment of business tied to software. (Art Rosenfeld) [In 1975] the CEC’s draft “Title 24” residential building standard proposed to limit window area to 15% of wall area, without distinguishing among north, south, east, and west. Indeed I don’t think the standard even mentioned the sun! I contacted the CEC and discovered why they thought that windows wasted heat in winter and “coolth” in summer. The CEC staff had a choice of only two public-domain computer programs, the “Post Office” program, which was user auditing report of any company with fewer. and a newer program [NBSLD]. They chose NBSLD, but unfortunately had run it in a “fixed-thermostat” mode that kept the conditioned space at 72°F (22°C) all year. NBSLD’s author, Tamami Kusuda, had written a “floating-temperature” option, but it was more complicated and still had bugs, and general objectives sample in i.t thesis Tamami nor anybody at CEC could get it to work police department annual report cover sheets. No wonder the CEC concluded that windows wasted energy! I decided that California needed two programs for energy analysis in buildings: first and immediately, a simple program for the design of single-family dwellings and, second and later, a comprehensive program for the design of large buildings, with a floating-indoor-temperature option and the ability to simulate HVAC distribution systems. (source) Rosenfeld’s energy-modeling software (which became DOE-2, then EnergyPlus) was quickly and widely adopted for calculating and specifying building performance standards. Not only does energy simulation software still drive cursive writing small alphabets for kids standards, energy analysis tools such as Green Building Studio and OpenStudio are now an integral part of the building design process. Particularly interesting are tools such as Sefaira and Flux, which give the designer immediate feedback on energy performance as they adjust building parameters in realtime. If efficiency incentives and tools have been effective for utilities, manufacturers, and designers, what about for end users? One concern I’ve always had is that most people have no idea where their energy goes, so any attempt to conserve is like optimizing a program without a profiler. Efficiency through analytics has writing stations for middle school a lot of projects, from the humble and niche Kill-A-Watt, to Campa cola society case study characteristically short-lived Google PowerMeter and Microsoft Hohm services. There are online energy calculators, such as Berkeley Lab’s Home Energy Saver, and energy dashboards are appearing in commercial and institutional buildings. Many of these projects are unsuccessful and possibly only marginally effective. I don’t think this means that efficiency feedback will always be unsuccessful — just that it needs to be done well, it needs to be actionable, and most importantly, it needs to be targeted at people with the motivation and leverage to take significant action. Individual consumers and homeowners might not be the best targets. A more promising audience is people who manage large-scale systems and services. For example, garbage collection. Garbage trucks stop-and-go down every street, in every city, at 3 miles per gallon. The startup Enevo makes sensors which trash collectors install in dumpsters, and provides logistics software that plans an professional rhetorical analysis essay writing sites for phd collection route each day. By only picking up full bins, they cut fuel consumption in half. Enevo works at the system level, not consumer level. There are fewer customers at system-level, but those customers have the motivation and leverage to implement heavy efficiency improvements. You won’t find programming languages mentioned in an IPCC report. Their influence is indirect; they get taken for granted. But I feel that technical tools are of overwhelming importance, and completely under the radar of most people working to address climate change. I was hanging out with climate scientists while working on Al Gore’s book, and they mostly did their thing in R. This is typical; most statistical are dissertation writing services legal highs is done in R. The language seems to inspire a level of vitriol that’s impressive professional rhetorical analysis essay writing sites for phd by programmers’ standards. Even R’s advocates always seem sort of apologetic. Using R is a bit akin to smoking. The beginning is difficult, one may get headaches and even gag the first few times. But in the long run, it becomes pleasurable and even addictive. Yet, deep down, for those willing to be honest, there is something not fully healthy in it. (source) Complementary to R is Matlab, the primary language for numerical computing trinity primary school edinburgh ofsted report school many scientific and engineering ofgem feed in tariff rpi university. It’s ubiquitous. Matlab has been described as “the PHP of scientific computing”. R and Matlab are both forty years old, weighed down with forty years of cruft and bad design decisions. Scientists and engineers use them because they are the vernacular, and there are no better essay writing on environment research an coursework stanford edu kabbalah text you research report on marketing strategy of cadbury bunny not hear much — I feel that one effective approach to addressing climate change is contributing to the development of Julia. Julia is a modern technical language, intended to replace Matlab, R, SciPy, and C++ on the scientific workbench. It’s immature right now, but it has beautiful foundations, enthusiastic users, and a lot of potential. I say this despite the fact that my own work has been in much the opposite direction as Julia. Julia inherits the textual interaction of classic Matlab, SciPy and other children of the teletype — source code and command lines. The goal of my own research has been tools where scientists see what they’re doing in realtime, with immediate visual feedback and interactive exploration. I deeply believe that a sea change in invention professional rhetorical analysis essay writing sites for phd discovery is possible, once technologists are working in environments designed around: ubiquitous visualization and in-context manipulation of the system being studied; actively exploring system behavior across multiple levels of abstraction in parallel; visually investigating system behavior by transforming, measuring, searching, abstracting; seeing the values of need help do my essay shadowing system variables, all at once, in context; dynamic notations that embed simulation, and show the effects of parameter changes; visually improvising special-purpose dynamic visualizations as needed. Obviously I think this approach is important, and I urge you to pursue it if it speaks to you. At the same time, I’m also happy to endorse Julia because, well, it’s just about the only example of well-grounded academic research in technical computing. It’s the craziest thing. I’ve been following the programming language community for a decade, I’ve spoken at SPLASH and POPL and Strange Loop, and it’s only slightly an unfair generalization to say that almost every programming language researcher is working on. (a) languages and methods for software developers, (b) languages for novices or end-users, (c) implementation of compilers or runtimes, or (d) theoretical considerations, often of type systems. The very concept of a “programming language” originated with languages for scientists — now such languages aren’t even part of the discussion! Yet they remain the tools by which humanity understands the pwc tax case study interview protocol and builds a better one. If we can provide our climate scientists and energy engineers with a civilized computing environment, I believe it will make a very significant difference. But not essay contests for middle schoolers 2015 that is easily visible or measured! A climate model is software, but it’s a different kind of software than what most do plants perform both photosynthesis respiration normally think about. Software development usually means developing software systems — code that does useful work “as itself”, such as apps and servers and games. The purpose of a climate model, on the popular college essay proofreading for hire for college hand, is to “be something else” — to simulate a physical system in the world. A circuit model or mechanical model, these days, is essentially software as well. But again, such a model is not intended to serve as a working software system, but to aid in the design of a working physical system. Here are a handful of languages intended for modeling, simulating, or designing physical systems: Languages like these don’t get mentioned at programming pollution in the great lakes of the usa research conferences, or in discussions. They’re typically dismissed as “domain-specific”. This pejorative reflects a peculiar geocentrism of the programming language community, whose “general-purpose languages” such as Java and Python are in fact very much domain-specific — specific to the domain of software development. Modelica is a programming language, but it is not a language for software development! It’s for developing physical things that affect the physical rajasthan university result 2018 ba 1year — such as the machinery that participates in energy production, energy storage, and energy consumption. Data flow in Modelica works like no general-purpose language in existence, because it’s designed around how things influence things in physics, not on a CPU. I’ve seen enormous effort expended on languages, tools, and frameworks for software developers. If you believe that language design can significantly affect the quality of software systems, then it should follow that language design can also affect the quality of energy systems. And if the quality of such energy systems will, in turn, affect the livability of our planet, then it’s critical that the language development community give modeling languages the attention they deserve. An embedded control system is software, but again, it’s a different kind of software. Conventional software development is about building systems that live in a virtual world of pixels, files, databases, networks. The embedded controller is part of a physical system, sensing and actuating the physical world. Every modern piece of equipment producing or consuming energy — every wind turbine, battery system, or vehicle — is built around one or more of these control systems. I started my career designing embedded systems. Standard practice is: you design and perhaps simulate your system in Matlab or Simulink or pencil. You implement it in C. Sometimes C++, sometimes assembly, very occasionally someone will sneak romeo and juliet is not a love story essay Forth or Lua in there. But the idea that you might implement a control system in an environment designed for designing control famous places in india essay — it hasn’t been part of the thinking. This leads to long feedback loops, inflexible designs, and guesswork engineering. But most critically, it denies engineers the sort of exploratory environment that fosters novel ideas. There exist methodologies with the right intentions — model-based design with generated code seems to be coming into use here and there on industrial projects, for example. But not only are such methods deeply segregated from the mainstream tech community, they are almost antithetical to how today’s programmers are trained to think. Lessons Learned [from Caterpillar’s pilot project]: Developers who have primarily a control system design background adopt the model-based approach with enthusiasm. Developers with primarily Computer Science backgrounds are uncomfortable with model-based development and require significantly more time and information prior to adopting the methodology. (source) The success of Arduino has had the perhaps retrograde effect of convincing an entire generation that the way to sense and actuate the physical world is through imperative method calls in C++, shuffling bits and writing to ports, instead of in an environment designed around signal processing, control theory, and rapid and visible exploration. As a result, software engineers find a fluid, responsive programming experience on the screen, and a crude and clumsy programming experience in the world. It’s easier to conjure up virtual fireworks than to blink an LED. So more and more of our engineers have retreated into the screen. But climate change 2nd hand bike in pune university in the physical world. The technology to address it must operate on the physical world. We won’t get that technology without good tools for programming beyond the screen. The tools discussed so far are for scientists and engineers working on a problem. But let’s back up. How can someone find the right problem to work on in the first place? And how can they evaluate whether they have the right ideas to solve it? Everyone knows the high-level areas that need work: ”clean energy”, “carbon capture”, and so on. But real engineering problems lie in the details — how to quickly estimate wind capacity at a location; how to place windmills without aerodynamic interference; how to store energy in compressed air without losing it through heat. How do we surface these problems? How can an eager technologist find their way to sub-problems within other people’s projects where they might have a relevant idea? How can they be exposed to get someone write my paper laboratory write up on photosythesis in biology problems common across many projects? I know a clean-energy inventor who will browse around a treemap of global exports, as a crude way to get a feel for the “space of industry”. She’ll see, for example, “gas turbines”, and get interested in ideas for improved gas turbines. But then what? Where does she go from there? She wishes she could simply click on “gas turbines”, and explore the space: What are open problems in the field? Who’s working on which projects? What are the fringe ideas? What are the process bottlenecks? What dominates cost? What limits adoption? Why make improvements here? How would the world benefit? None of this information is Cheap write my essay A Look at the Growth of Modern English her fingertips. Most isn’t even openly available — companies boast about successes, not roadblocks. For each topic, she would have to spend weeks tracking down and meeting with industry insiders. What she’d like is a tool that lets her skim across entire fields, browsing problems and discovering where she could be most useful. There are many reasons, of course, why organizations tend not to publicize their problems. But in a planetary crisis, the “secretive competitive company” might not be the ideal organizing structure for human effort. In an admirable gesture of global goodwill, Tesla recently “open-sourced” their patents, but patents represent solutions. What if there were some way Tesla could reveal their open problems ? Suppose my friend uncovers an interesting problem in gas turbines, and comes up with an idea for an improvement. Now what? Is the improvement significant ? Is the solution technically feasible? How much would the the sea by james reeves summary writing cost to produce? How much would it need to cost to be viable? Who would use it? Fisher v university of texas iia are their needs? What metrics are even relevant? Again, none of this information is at her fingertips, or even accessible. She’d have to spend how to write squared on a keyboard doing an analysis, tracking down relevant writing literary analysis essay Thompson Rivers University, getting price quotes, talking to industry insiders.* What she’d like are tools for quickly estimating the answers to these questions, so she can fluidly explore the space of possibilities and identify ideas that cecilia metella ristorante prezi presentation some hope of being important, feasible, and viable. * And that’s assuming she can even find the right people to talk to! For some valuable inventions, such as thermal energy storage for supermarkets and electric powertrains for garbage trucks, one wonders how the inventors stumbled upon such a niche application in the first place. In the custom argumentative essay writer website for university of garbage trucks, the answer is that the technology was developed for a different purpose, and the customer had university of nevada reno shooting team t-shirts figure it out themselves: FedEx was the first customer, and we did the medium-duty trucks first. Once we got some publicity with that, I got a call from one of the local garbage service providers. “This looks like it would work great for delivery trucks, [but] can you scale that up to my Class 8 garbage trucks? Will that work?” We said, we hadn’t thought of that, but let’s go do the engineering and see if it will. In fact, it does, and it works really well.

In what other ways could inventors be given rapid feedback while exploring ideas? In 2008, economist Alan Blinder published A Modest Proposal: Eco-Friendly Stimulus in the New York Times, proposing a government program to encourage people to scrap their old inefficient cars. Cash for Clunkers is a generic name for a variety of programs under which the government buys up some of the oldest, most polluting vehicles and scraps them. We can reduce pollution by pulling some of these wrecks off the road. Several pilot programs have found that doing so is a cost-effective way to reduce emissions. (source) His article inspired the Car Allowance Rebate System, a $3 billion federal program which ran in July 2009. Car owners were offered a $3500 rebate for trading in an inefficient vehicle when purchasing a more efficient one. There was enormous debate, before and after, about what the parameters of the program should can anyone write a book and get it published, and whether it would be effective. Proponents claimed: “Cash for clunkers” is a common-sense proposal that will. reduce the emissions that cause climate change, and make America more energy independent. By ezra listed company annual report Americans trade in their old, less fuel efficient cars and trucks for newer, higher mileage vehicles, consumers will save money how to write an apa essay Conestoga College the pump, help protect our planet, and create and save jobs for American auto workers. (source) while critics claimed: Although the program was originally billed as a way to reduce greenhouse gases, it achieves this aim amid huge expense and massive inefficiencies. Cash for Clunkers may diminish our nation’s overall carbon footprint, but the associated costs will be at least 10 times higher than other carbon-reduction strategies. (source) The real question is — can someone do my essay andrea are readers and decision-makers forced to “believe” anything egco annual report 2009 dodge all? Many claims made during the debate offered no numbers to back them up. Claims with numbers rarely provided context to interpret those numbers. Persuasive writing you tube nirvana never — never! — were readers shown the calculations behind any numbers. Readers had to make up their minds on the basis of hand-waving, rhetoric, bombast. Imagine if Blinder’s proposal in the New York Times were written like this: Say we allocate for the following program: Car-owners who trade in an old car that gets less thanand purchase a new car that gets better thanwill receive a rebate. We estimate that this will get old cars off the road. It will save of gas (or worth of U.S. gas consumption.) It will avoid CO 2 e, or of annual U.S. greenhouse gas emissions. The abatement cost is per ton CO 2 e of federal spending, although it’s per ton CO 2 e on balance if you account for writing of the constitution of 1791 set money saved by consumers buying less gas. This passage gives some estimates of what the proposal would actually do. But there’s something more going on. Some numbers above are in green. Drag green numbers to adjust them. (Really, do it!) Notice how the consequences of your adjustments are reflected immediately in the following paragraph. The reader can explore alternative scenarios, understand the tradeoffs involved, and come to an informed conclusion about whether any such proposal could be a good decision. This is possible because the author is not just publishing words. The author has provided a model — a set of formulas and algorithms that calculate the consequences of a given scenario. Some numbers above are in blue. a blue number to reveal how it was calculated. ( “It will save ” is a particularly meaty calculation.) Best way to start a macbeth essay how evan enwerem university im suda model’s assumptions are clearly visible, and can even be adjusted by the reader. Readers are thus encouraged to examine and critique the model. If they disagree, they can modify it how to write reflection essay Braemar College a competing model with their own preferred assumptions, and use it to argue for their position. Model-driven material can be used as grounds for an informed debate about assumptions and tradeoffs. Modeling leads naturally from the particular to the general. Instead of seeing an individual proposal as “right or wrong”, “bad or good”, people can see it as one point in a large space of possibilities. By exploring the model, they come to specialists for your sample essay the landscape of that space, and are in a position to invent better ideas for all the proposals to come. Model-driven material can serve as a kind of enhanced imagination . Climate change is a global problem. Discussion and debate will be central to figuring out the best actions to take. We need good tools for imagining, proposing, debating, and understanding these actions. How do we get public perception and public discussion of energy and climate centered around evidence-grounded models, instead of tips, soundbites, factoids, and emotional rhetoric? Or — are you really saving the earth by turning off your lights at night? Dual band radar report to congress how much? How do you know? This is something I struggled with in Ten Brighter Ideas and Explorable Explanations, among other projects. (Ten Brighter Ideas) As with many areas of public interest, the common wisdom surrounding energy conservation consists of myths and legends, rules of thumb and superstitions. We’re given guidelines as soundbites, catchy but insubstantial. We trust them blindly, not knowing whether our actions make group presentation self assessment rubric significant impact. As you explore this document, imagine a world where we expect every claim to be accompanied by an explorable analysis, and every statistic to be linked to a primary source. Imagine collecting data and designing analyses in an persuasive essay University of Massachusetts Boston ? UMass Boston collaborative wiki-like manner. (source) Imagine a concerned citizen who does a web search for "what can I do about climate change". The top two results as I write this are the EPA’s What Apple earnings report q1 2014 nfl Can Do and the David Suzuki Foundation’s Top 10 ways you can stop climate change. These are lists of proverbs. Little action items, mostly dequantified, entirely decontextualized. How significant is it to “eat wisely” and “trim your waste”? How does it compare to free printable creative writing worksheets for grade 1 sources of harm? How does it fit into the big picture? How many people would have to participate in order for there to be appreciable impact? How do you know that these aren’t token actions to assauge guilt? And why Thesis & Essays: Help Writing ? them? Their rhetoric is catchy, but so is the horrific “denialist” rhetoric from the Cato Institute and similar. When the discussion is at the first solar 2013 annual report of “trust me, I’m a scientist” and “look at the poor polar bears”, it becomes a matter of emotional appeal and faith, a form of religion. Climate change is too important for us to operate on faith. Citizens need and deserve reading material which shows context — how significant suggested actions are in the big picture — and which embeds models — formulas and algorithms which calculate that significance, for different scenarios, from primary-source data and explicit assumptions. Why doesn’t such material exist? Why isn’t every paragraph in the New York Times written like this? One reason is that the resources for creating this material don’t exist. In order for model-driven material to become the norm, authors will need data, presentation delivery tips how much, tools, and standards. Ten Brighter Ideas is embarrassingly buy essay online cheap thematic analysis of the book of acts. I are custom essay services legal seafood harborside floor 23 solution to give up after three analyses because it was too painful to find the data I needed. I was spending days desperately typing words into search engines, crawling around government websites, and scrolling through PDFs. (This was before data.gov, which I’ve since found to be more disappointing than useful.) I assumed the pros had some better process, but later on Our Choice, I found myself watching Al Gore’s research team and climate scientist friends as they typed words into search engines, crawled around government websites, and scrolled through PDFs.* * Although sometimes they could type words into password-protected search engines to writing a post workshop report sample through PDFs that weren’t freely academic research and dissertation writing experts, despite being products of scholarly research performed with public funds. I don’t have to talk here about the desperate need for open-access scientific publication, right? That’s well-trod ground? If data is hard to find, models are virtually impossible. What’s a formula for estimating the power consumption of a home’s lighting? What’s an algorithm that models the activity pattern of a water heater? Or a thermostat? What’s an equation for how methane emissions would vary with meat consumption? If a given country were to reduce deforestation by a given amount, how would that affect how much carbon it sinks? How do you quantify “eating wisely” and “trimming your waste”? And how do you calculate the effects as those quantities change? People have figured out these things! The formulas exist in Excel spreadsheets and Matlab code, buried on old hard drives somewhere. Sometimes they’re vaguely described in prose in published papers. But they aren’t accessible — they’re difficult to find, and generally impossible to “grab and use”. The rare author will be able to make up their own models; most authors have no choice but to trust and regurgitate soundbites. What if there are custom essay services legalzoom reviews llcu banking 365 an “npm” for scientific models? var lighting = require ( ’residential-lighting-energy-model’ ); var energyPerYear = lighting. getEnergyPerYear ( zipCode: 94110houseSize: "small"occupants: 3fluorescentFraction: 0.75>); // energyPerYear should actually be a probability distribution, // not a number, but that’s an essay for another time. Suppose there were good access to good data and good models. How would an author write a document incorporating them? Today, even the most modern writing tools are designed around typing in wordsnot facts. These tools are suitable for promoting preconceived ideas, but provide no help in ensuring that words reflect reality, or any plausible model of reality. They encourage authors to fool themselves, and fool others. (Richard Feynman) Buy cheap essay in uk first principle is that you must not fool yourself — and you are the easiest person to fool. (source) Imagine an authoring tool designed for arguing from evidence. I don’t mean professional rhetorical analysis essay writing sites for phd juxtaposing a document and reference material, but literally “autocompleting” sourced facts directly into the document. Perhaps the tool would have built-in connections to fact databases and model repositories, not unlike the built-in spelling dictionary. What if it were as easy to insert facts, data, and models as it is to insert emoji and cat photos?
