Waterproof Bat Handle Toggle

Wednesday, January 13th, 2010

We want to provide  a short description of what a Toggle switch is and how it can be incorporated into your design. We are featuring NTE’s Waterproof Toggle and below you will find a link with the specifications for various kinds.

http://www.nteinc.com/switches/pdf/waterproof.pdf 

A toggle switch is a mechanism that does one of only two things: “On” and “Off.” The familiar bat-handle switch might provide power to a piece of farm equipment, or nestle among many switches and dials on an airplane control panel. Other examples are the familiar up/down handle of a light switch, and the fancier button that turns on your stereo. Some circuit breakers operate by way of a toggle switch.

Definition

The noun “toggle” refers to a pin or knob that keeps something fastened, with applications in the nautical, fashion and carpentry worlds. A knot with a toggle will not untie, and put a ship at danger. A toggle is what a car coat wearer expects to button up. A bolt with a movable crosspiece at the end holds fast in the wall.
The intransitive verb “toggle” means to switch between two options, which brings our discussion to the word “switch.” Relevant meanings for the noun “switch” include “a shift or change” and “a device that shifts or changes something.”
It follows, then, that a toggle switch refers to a mechanism that changes status. An electric toggle switch is a spring-loaded mechanical device that opens or closes an electric circuit when toggled, or manually moved. Depending upon its position, the switch completes or interrupts the flow of electricity.

History

Joseph Swan demonstrated his new invention, the incandescent lamp, in 1878, and Thomas Edison, his similar invention within the year. What was needed was an effective on/off device. Englishman John Holmes invented the first quick-break light switch in 1884. In 1898, Newcastle-upon-Tyne in northeastern England became the first electricity-lighted city, thanks in part to the toggle switch.

Could the global network be a thousand times more efficient?

Tuesday, January 12th, 2010

By Ron Wilson, Executive editor — EDN, 1/12/2010

A research project that apparently began as a speculation among Bell Labs engineers in Ireland and the UK has grown into a global consortium determined to reduce energy consumption in the global information network. The Green Touch initiative, announced Monday, includes service providers AT&T, China Mobile, Portugal Telecom, Swisscom, and Telefonica; academic research labs The Massachusetts Institute of Technology (MIT) Research Laboratory for Electronics (RLE), Stanford University Wireless Systems Lab (WSL), and the University of Melbourne  Institute for a Broadband-Enabled Society (IBES); government and nonprofit research institutions CEA-LETI Applied Research Institute for Microelectronics (Grenoble, France), IMEC (headquarters: Leuven, Belgium), and The French National Institute for Research in Computer Science and Control (INRIA); and industrial labs Bell Labs, Samsung Advanced Institute of Technology (SAIT), and Freescale Semiconductor.

These disparate organizations have joined the cause to find three orders of magnitude in energy savings in global communications, even as the demand for bandwidth continues to grow exponentially.

“In the next five years we hope to identify the enabling technologies for three orders of magnitude improvement in efficiency,” explained Sam Samuel, Bell Labs executive director for Ireland and the UK. “The actual equipment to implement those savings will come later, after the technologies are identified.”

Samuel said the project began within the Labs as a theoretical question: Just how much more efficient could the global network be? The researchers started with an idealized model: a network in which each endpoint was connected to every other by an ideal link, and each endpoint contained an ideal, massive switch to deal with all those connections. In order to minimize the number of switching events there was no hierarchy” just a single, flat, fully populated mesh. In this case, Samuel said, physical limits on transmission efficiency and switching energy would allow the network to be 1012 times more efficient than today’s technology.

That study proved that the question was worth pursuing. But it was quantitatively almost meaningless, since nothing approaching the model could actually be built. So the researchers moved their modeling closer to reality. The next step was to isolate the core technologies in today’s network and explore what savings might be physically possible for them.

The researchers found that without breakthroughs in fundamental physics, wireless transmission could be 103, and fixed fiber transmission 108 times more efficient than it is now. These assessments assumed today’s physics, but massive deployment of as yet unidentified technology to reduce energy. Samuel cited such ideas as near-threshold power supply voltages, adiabatic circuit designs, drastically smaller cell sizes for wireless networks, and holographic coding for optical transmission as the sorts of technologies that might be needed. But he said the program at this point has not begun to identify actual target technologies.

Next, the researchers looked at projections. Anywhere they looked, Samuel said, it appeared that data rates were growing at 30 to 50% annual rates. But wireless data rates were an exception, growing much faster. “It appears from the growth rates as if wireless networking is in its infancy and just experiencing its first growth spurt,” Samuel said. “Our model suggests that by somewhere between 2011 and 2013, wireless networks will dominate energy consumption.” A shift to smaller cell sizes, in effect moving traffic from the air into fiber, could delay that crossover.

Such studies, correlated and combined with models of network growth, led to the conclusion that an aggregate thousand-fold improvement in network efficiency is feasible. But the effort will require new technologies in computing, switching, and transmission. As well, the goal will demand new ways of thinking about how the network is structured. For example, computing is always expensive. You want to minimize it whenever possible. That may mean thinking very differently about how to employ the computing cloud in tandem with local computing resources. It suggests embedding provisions for quality-of-service and security deeply in the protocol, rather than trying to implement these functions by applying intensive computing to a packet stream that was never intended to enable such things. And the goal could mean emphasizing optical transmission, which can be made nearly lossless, over wireless transmission, which cannot.

Yet Samuel cautioned that the enabling technologies the consortium identified had to be reachable by an evolution of today’s physical network. “No one is going to throw out their hardware and software,” he observed. “And if you come up with an idea that no one adopts, you haven’t solved the problem.”

So why is the beginning of 2010 the right time for a global 14-organization consortium? Because there is no time for inaction, Samuel says. “As an engineer, how often is it that I work on a problem that not only helps my company, but could change the lives of my children? I can’t walk away from this sort of problem.”

USING THERMALLY PROTECTED MOVS IN TVSS OR POWER SUPPLY APPLICATIONS

Thursday, January 7th, 2010

Paul Traynham, Field Application Engineer, Littelfuse®, Inc.

ABSTRACT

Metal Oxide Varistors (MOVs) are commonly used for transient over-voltage suppression in many  applications  such  as:  Transient  Voltage  Surge  Suppressors  (TVSS),  Uninterruptable  Power Supplies  (UPS),  AC  Power  Taps,  AC  Power  Meters  or  other  products.  Events  such  as  lightning, inductive load switching, or capacitor bank switching, are often the sources of these transients. Additionally, in these applications, the possibility for a sustained abnormal over-voltage, with a limited current condition may exist which necessitates the need to protect the MOVs from an over-dissipation thermal condition.

The UL1449 standard clearly defines abnormal over-voltage, limited current test conditions.  The intent of this paper is to outline these conditions, explore the use of MOVs in combination with a TCO (Thermal Cut-Off or Thermal Cut-Out) device, and compare performance with a thermally self-protected MOV technology.  Graphs depicting the Epoxy temperature of MOVs without thermal protection will be shown along with a MOV/TCO combination and the internally protected MOV.

1.   Introduction

 Under normal operating conditions, the AC line voltage applied to an MOV is not expected to exceed the MOV’s Maximum ACRMS  Voltage Rating. Occasionally, over-voltage transients may occur that exceed these limits.  These transients are clamped to a suitable voltage level by the MOV provided the transient energy does not exceed the MOV’s maximum rating.  If, unlike a short duration transient, an MOV is subjected to a sustained abnormal over-voltage, limited current condition (as is required in UL1449), the MOV may go into thermal runaway resulting in overheating, smoke, and potentially fire. For end products to comply with UL1449, some level of protection must be afforded to the MOV to prevent this failure mode.   That protection has traditionally been a thermal fuse or Thermal Cut-Off (TCO) device.

 2.   The UL1449 Abnormal Over-voltage Standard

 In AC line applications, Neutral and Ground are typically near or at the same potential. In the event of a loss of a Neutral-Ground connection, there exists a risk that a sustained over-voltage may be applied to an MOV that is rated for a much lower continuous voltage.  In an unlimited current condition, the MOV will first fail short, but due to the high amount of energy available, it most often ruptures instantaneously. If, however, there are loads tied to the AC line that limit current flow, the MOV can overheat  and  potentially  cause  the  TVSS  device  to  overheat  resulting  in  smoke,  out-gassing  and eventually fire. This potential condition is specifically identified and addressed in the UL1449 TVSS Standard. See Table 1. In many cases, it requires that end-product manufacturers include a thermal protection element for an MOV.

 (a) For device ratings not specified in this table, the test voltage shall be the maximum phase voltage (if available) or twice the conductor pair voltage ratings up to 600V max.
 
 
 

Table 1: Test Voltage Selection Table

 

 

Table 1. defines the test voltage that should be applied to various TVSS devices depending on the designer’s desired device1  rating.  Each test voltage is applied across each conductor pair with a short circuit current of 5A, 2.5A, 0.5A and 0.125A respectively across each of four TVSS devices.  Since this test is destructive, four devices are needed to test for each of the four short circuit currents. The four devices must be energized for 7 hours, or until current or temperatures within the TVSS device attain equilibrium, or until the TVSS becomes disconnected from the AC Line.

 

For example, in a standard 120V AC Line application, the requirement is for a 240VACRMS  test voltage to be applied across all conductor pairs.   There are three pairs; Line-Neutral (L-N), Line-Ground (L-G), and Neutral-Ground (N-G).  This test voltage is chosen because very commonly in the U.S., 120V AC power is commonly fed from a center-tapped 240V transformer. If a break occurs at XX (see Figure 1.), then the load in the bottom phase acts as a current limiter and the line fuse may not clear. Thermally unprotected MOVs are typically rated from 130Vacrms to 150Vacrms and will heat up, out- gas and may catch fire in such circumstances.

Bye, bye bad 2009. Welcome to a sunnier 2010

Tuesday, January 5th, 2010

By Rob Spiegel, Contributing editor — Electronic Business, 1/5/2010

It goes without saying that 2009 was a tough year for the electronics industry. With the notable exception of laptops “ which grew in unit shipments throughout the year“ and LCD-TVs, most product segments suffered significant declines. That started to change in the third quarter as year-over-year and sequential growth returned to many product groups. Desktop PCs are likely to remain sluggish as buyers turn to laptops that are cheaper and come with robust functionality.

The industry managed its inventory better during this recession. During the 2000/2001 recession, the industry had to eat through a mountain of inventory before factories restarted. This time around, any increase in demand should prompt production. But the current recession has been more broad-based and far deeper than the last recession, so the industry still has some recovering to do before revenue returns to pre-recession highs.

Most industry observers predict that the first half of 2010 will continue to see growth returning, but without a real boom. The second half of 2010 is likely to be more robust. Here is a look back at 2009 and forward at the 2010 forecasts for the consumer electronics, PC/laptops, medical, and military segments.

Consumer electronics: fueled by HD TVs and Internet connected devices

Consumer electronics took a big hit during 2009. It has been a challenging year, said Norm Bogin, VP of research for digital entertainment at In-Stat, a research company in Scottsdale, Ariz, owned by the same parent company as EDN. We just did a survey on holiday spending in the US and the intent to buy is down, he said during a late 2009 interview.

Even so, there are some products that look good. HD TVs are still high on the shoppers list, but in general, 2009 is down from 2008, and 2008 was pretty weak, he said. The demand for HD TVs is partly prompted by this seasons high discounting.

Bogin did see a few other bright spots this year. E-books and e-readers are strong,he said. DVDs are down, but Blue-ray is up.

In 2010, we can expect consumer electronics to struggle at the beginning. The first half of 2010 will still be a challenge, but certain products will grow, said Bogin. Blue-ray, e-readers, mobile Internet devices, and HD TVs will grow,he said, further pointing to Internet TV as a growth market in 2010. Internet TV will grow, and anything that enables Internet.

The second six months of 2010 look brighter, according to In-Stat. The second half of 2010 should be better, since we should be through the recession and in a job creation mode, said Bogin. As soon as unemployment goes down, spending on consumer electronics will go up.

PCs: Laptops outsell desktops

2009 saw a remarkable move in the PC/laptop sector, as laptops passed desktops in unit sales for the first time. Notebooks were definitely strong,said Matthew Wilkins, principal analyst for compute platforms research at iSuppli Corp. They provided low-cost mobile computing when pockets and spending was getting hit hardest. He noted that notebooks were the growth driver for the whole PC industry.

Jim McGregor, chief technology strategist at In-Stat, agreed that laptops saved the PC industry this year. In 2009 we started to see a lot of innovation take hold in the netbook and ultra-thin category,he said. I would say the ultra-thin is going to win out. They’re very sexy and we saw the price drop from $748 down to $599 right away.

He noted that life for the desktop was difficult this year. We are almost at the point where the desktop has to fight for its identity, said McGregor. For the home, its still a good device, but ita unlikely to be your primary communication device.

2010 will see a pickup in the sector as a whole, with laptops still leading the way. Due to the replacement effect, the notebook PC will still be strong, and the desktop will still be weak, said iSuppli Wilkins. We are also looking forward to seeing how CULV [consumer ultra-low voltage] laptops develop and engage the market.  He also expects the introduction of microprocessors with integrated graphics to be a major milestone for the PC platform in 2010.

In-Stats McGregor expects the PC market to explode in 2010. Electronics is leading the way in this recovery, he said. Going forward, our industry is growing very rapidly. Business, consumer, everything across the board is looking good for 2010.

He expects the growth to be fueled by innovation. You’re going to see an explosion of design in 2010  not just form factor, but changes in terms of other technologies making their way into PCs, said McGregor. You’ll see I/O capabilities and a lot of differentiation among OEMs and ODMs for crafting distinctive products.  He points to Dell coming out with a dual-mode latitude with LYNX and Microsoft. Also, Acer and Toshiba are on a tear, said McGregor. Look for longer battery life and longer performance levels.

Medical: Growth is robust, healthcare bill or not

The medical sector did well though the recession and looks to be big for 2010, as well  but not just because of the potential for a healthcare bill. There are two camps regarding a potential healthcare bill, said Harley Feldberg, president of Avnet Electronics Marketing, the component arm of Phoenix-based distributor Avnet Inc. One believes expanded healthcare will mean more health services, therefore more medical equipment. The other camp believes a healthcare bill is more about how to pay for healthcare and not about healthcare growth.

Even so, the sector had a decent 2009 and looks bright for 2010. The sector did well during the recession and the aging population will help it grow in 2010, said Feldberg. He sees a bright future for the sector. In handicapping, we see strong growth in medical. We are adding technical support.

The growth in medical electronics during 2010 will come in two areas: devices consumers use to monitor specific health issues and devices used by medical professionals, experts believe. In consumer medical equipment, one growth market is home monitoring equipment for diabetes. This is a problem now not only in the Western world, but also in countries such as India. So the market for blood glucose monitors and insulin pumps is fast growing,said Seema Deshpande, general manager for medical/high reliability, high performance analog at Texas Instruments Inc. We also see a growing trend for health and wellness related medical equipment like electronic exercise monitoring.

Yet another area where TI sees growth is in patient monitoring equipment using wired and wireless connectivity for remote monitoring of vital signs in hospitals, doctors office and in homes.

Growth is also projected for equipment used by medical professionals. We continue to see a lot of innovation in medical imaging,said Deshpande. Semiconductor innovation has brought about a trend to make equipment more accessible and affordable by enabling lower power and smaller size. Growth areas include ultrasound equipment that is becoming increasingly portable, even handheld, and remote monitoring equipment.

 

Military: Good, but not a growth market

Given the new surge in Afghanistan and the ongoing military presence in Iraq, it would seem the military sector would boom for the US electronics supply chain, recession or not. Avnet Feldberg believes that some of the demand for military components may be slipping outside North America.

We are a little puzzled by the market conditions in military and defense, said Feldberg. Business isn’t as buoyant as people would think.  Even though much of the military purchasing is restricted to North America, Feldberg believes some systems are being procured elsewhere. A defense contractor could sublet a portion to a French company, he noted.

Looking forward, Feldberg believes 2010 will be a good year for the sector, but not particularly robust. I think it will continue to be a good market, he said. I dont see a lot of growth in 2010, but its not particularly a growth market.

While military equipment may be slow growing, the components used in defense are finding their way into other applications. In the HiRel [high reliability] market, which has traditionally been focused on defense and avionics, we see interesting new applications for industrial, medical, and consumer markets that require resistance to higher temperatures, smaller size, and lower power, said TIs Deshpande. In the industrial market, railway lighting applications require product longevity in a high-temp environment.

Deshpande noted this also applies to components used in harsh environments such as downhole drilling and undersea cabling. Military components are also being used in medical applications.

High-reliability devices or enhanced products are increasingly sought after for sterilization equipment or in imaging and radiation applications, said Deshpande.

Another growth area for traditional military components is in space applications. We are seeing continued year-on-year growth in the space market,said Deshpande. The space industry requires that semiconductors are resistant to radiation effects and meet mission lifetime objectives.

Clean Energy Debate

Friday, January 1st, 2010

Below you will find an interesting article written back in Oct 2009 by Brian Coppa from the Green Business Examiner

As the health care debate winds down, the next major national debate will focus on energy reform. The investor coalition Ceres and the Clean Economy Network organized a clean energy debate forum this week at the White House including corporate executives from more than 100 companies, representing a wide variety of industries including renewable energy, information technology and athletic apparel. The business leaders met with Senators Sherrod Brown (D-Ohio), who introduced a clean energy finance bill this past summer, Mark Pryor (D-Ark.) and Debbie Stabenow (D-Mich.), all of whom are critical to passing the Clean Energy Jobs and American Power Act introduced last week by Senators John Kerry (D-Mass.) and Barbara Boxer (D-Calif.).

The full list of companies represented is available at the official Department of Energy (DOE) site, and one glimmering fact, is the lack of representation from a company located in the state of Arizona, which is a state with enormous solar power potential. Even though Phoenix, Arizona is hosting the Greenbuild International Conference and Expo November 11-13 of this year, where former U.S. Vice President, 2007 Nobel Peace Prize winner, and environmental advocate, Al Gore will be the keynote speaker, the state still lacks significant corporate development in the clean energy sector, and manufacturing in general.

During the forum in Washington, executives also met with Energy Secretary Steven Chu, Commerce Secretary Gary Locke and White House Office of Energy and Climate Change Policy Director Carol Browner. Chu warned that if Congress does not pass climate change and energy reform legislation soon, the U.S. will likely be surpassed by China as a global leader in the production of wind turbines, solar panels, solid state lighting and other clean energy technologies. According to the DOE, China invests approximately $12.6 million in clean energy every hour, and the nation is ratcheting up to generate 100 gigawatts from wind turbines by 2030. In essence, if the U.S. lapses in building a competitive clean energy infrastructure, including complete supply chains for related technology, while signing onto a new United Nations (U.N.) greenhouse gas emissions (GHG) reductions treaty, which will require significant reductions in fossil fuel energy usage, it may simply be exchanging foreign oil imports for Chinese or other country’s green energy imports. Thus, foreign oil dependence and ramifications for national security will be simply transferred to leading foreign clean energy manufacturing countries. Currently, the U.S. ranks behind Germany, Japan and China in terms of solar capacity.

Mainly, the business leaders descending on Washington this week have urged members of Congress to pass a comprehensive climate change bill, which they forecast will foster billions of dollars in clean energy investments and ease the nation’s dependence on foreign oil, which has been a cause for natural gas advocates such as T. Boone Pickens, while creating millions of green jobs in the process. The Congressional Budget Office estimated that the original related House bill entitled the American Clean Energy and Security Act would only increase energy costs for the average household by the price of a postage stamp, 44 cents, each day. The White House has welcomed the corporate involvement and its financial backing for this capstone climate change legislation, which is one of the major prongs of Obama’s overall agenda, including the green energy stimulus, as it will face a heated battle with Congressmen and lobbyists associated with the oil and coal industry in the coming months.

Moreover, a related business group called We Can Lead is heading a campaign on Capitol Hill this week including 150 business leaders from utility companies and the clean energy industry that involves 35 lobbying meetings. Twenty-eight companies and labor and green advocacy groups such as: United Technologies, Johnson & Johnson, GE, Weyerhauser, the Nature Conservancy and the Environmental Defense Action Fund are launching a seven-figure advertising campaign in support of comprehensive climate change legislation to win the clean energy debate. A barrage of television commercials is expected to attract national support, analogous to the heath care reform initiative.

Amidst the lobbyist activity and legislative discussions in Washington, a vast majority of Americans, across all political parties, strongly support development and funding of solar energy, and their support for solar has remained relatively unchanged over the last year. These and other findings were reported today in the 2009 SCHOTT Solar Barometer (TM), which is a nationally representative survey conducted by independent polling firm Kelton Research. 

The survey stated that 92 percent of Americans consider it important for the U.S. to develop and use solar energy. This strong support for solar is essentially the same as the 94 percent figure indicated by the June 2008 poll result with the same question being posed. The difference is within the margin of error for both polls. This support for solar power is consistent across political party affiliation with 89 percent of Republicans, 94 percent of Democrats and 93 percent of Independents agreeing that it is important for the U.S. to develop and use solar power.  

In addition, 77 percent, nearly eight of ten, of Americans feel that the development of solar power, and other renewable energy sources, should be a major priority of the federal government, including the necessary funding for bringing it to fruition. This sentiment also remains the same since June 2008 with a tally of 77 percent. What’s more, the study also showed that if people had to choose one energy source to financially support if they were President, 43 percent of Americans would opt for solar over other sources such as wind (17%), natural gas (12%) and nuclear (10%).

According to a recent study conducted by the environmental group Greenpeace and the European Renewable Energy Council, clean energy will create more jobs than coal. By 2030, there will have been 2.7 million more jobs created than if countries were to retain their current coal and other fossil fuel energy production levels. These findings provide additional carrots needed for both the U.S. and other major countries to agree to a new United Nations global warming reduction pact in Copenhagen in December.

In comparison to the health care debate, there appears to be a much more unified national sentiment for clean energy technology, which is linked to the overall climate change and energy reform initiative of the Obama administration. The transformation towards a clean energy economy would offer a facelift to America’s manufacturing sector, particularly hard hit by the recession beginning in December 2007. Numerous recently closed factories for the production of: automobile parts, chemicals, coatings, raw materials, aerospace turbines, computer components, microchips and other electronic components are excellent candidates for the transition towards the manufacturing of clean energy or energy-efficient products such as: solar panels, advanced batteries, ethanol fuel, innovative hybrid electric vehicles, concentrating solar dishes, wind turbine blades, and carbon storage components. In particular, as more semiconductor companies outsource production to Asia, an emerging opportunity exists for the utilization of idle silicon-based microchip process equipment for the production of silicon-based solar cells due to some overlaps in materials and techniques that are administered.

Hoping this information continues to create innovation and technology R & D toward a green sustainable future. Its more that corporate social responsibility its the future resting in our capable hands.

Revolution in Clean Energy Technologies

Friday, January 1st, 2010

WASHINGTON, DC, October 26, 2009 (ENS) – Liquid metal grid-scale battery technology that could enable constant energy supply from intermittent renewable energy sources, such as wind and solar power…

 A bioreactor that has the potential to produce a flow of gasoline directly from sunlight and carbon dioxide using two microscopic organisms and ending U.S. reliance on foreign oil…

New synthetic enzymes that could make it easier and more affordable to capture climate warming carbon dioxide emissions from power plants and factories…

Crystal growth technology that could lower the cost of developing light emitting diodes, LEDs, for energy efficient lighting…

These innovations and 33 others are in America’s energy future – funded today by the federal government through a new agency within the Department of Energy.

Energy Secretary Steven Chu announced today that $151 million in funding for 37 research projects is being awarded through the department’s recently-formed Advanced Research Projects Agency-Energy, ARPA-E.

This is the first round of projects funded under ARPA-E, which is receiving total of $400 million of economic stimulus funding under the American Recovery and Reinvestment Act.

In announcing the selections, Energy Secretary Steven Chu said, “After World War II, America was the unrivaled leader in basic and applied sciences. It was this leadership that led to enormous technological advances. ARPA-E is a crucial part of the new effort by the U.S. to spur the next Industrial Revolution in clean energy technologies, creating thousands of new jobs and helping cut carbon pollution.”

ARPA-E’s mission is to develop “nimble, creative and inventive approaches” to transform the global energy landscape while advancing America’s technology leadership, Chu said.

This first ARPA-E solicitation received 3,600 initial concept papers. Of those, some 300 full applications were requested and ultimately 37 final awardees through a rigorous review process with input from multiple review panels composed of leading U.S. energy science and technology experts and ARPA-E’s program managers. Evaluations were based on the potential for high impact on ARPA-E’s goals and scientific and technical merit.

The 37 grants will go to projects with lead researchers in 17 states. Of the organizations selected for funding, 43 percent are small businesses, 35 percent are educational institutions, and 19 percent are large corporations.

Scientists at the United Technologies Research Center are developing new synthetic enzymes that could make it easier and more affordable to capture carbon dioxide emissions from power plants and factories. If successful, the effort would mean a much lower energy requirement for industrial carbon capture and lower capital costs to get carbon capture systems up and running. This major breakthrough that could make it affordable to capture the carbon dioxide emissions from coal and natural gas power plants around the world.

General Motors received funding for development of a “shape memory alloy energy recovery device” to convert waste heat from car engines into electricity. This development could increase fuel efficiency in cars – most energy is lost as heat – and could be used in many other heat recovery applications.

The all-liquid metal battery, created by Professor Don Sadoway at the Massachusetts Institute of Technology, is based on low cost, domestically available liquid metals. It has the potential to break through the cost barrier required for mass adoption of large scale energy storage as part of the nation’s energy grid.

If this project is successful, it will create a new class of batteries that Chu says will allow the U.S. to regain technology leadership in grid scale energy storage and enable constant energy supply from intermittent renewable energy sources, such as wind and solar power. This in turn will enable their widespread deployment on the U.S. grid to reduce greenhouse gas emissions.

If deployed at homes, it could allow individual consumers the ability to be part of a future “smart energy Internet,” where they would have much greater control over their energy usage and delivery.

Researchers at the University of Minnesota have developed a bioreactor that has the potential to produce gasoline directly from sunlight and CO2 using a symbiotic system of two organisms. First, a photosynthetic organism directly captures solar radiation and uses it to convert carbon dioxide to sugars. In the same area, another organism converts the sugars to gasoline and diesel transportation fuels.

A proposal for novel crystal growth technology developed by Momentive Performance Materials could lower the cost of developing light emitting diodes, LEDs, which are 30 times more efficient than incandescent bulbs and four times more efficient than compact fluorescents. This higher quality, low-cost material would offer breakthroughs in lowering costs of finished LED lighting, accelerating mass market use, and decreasing U.S. lighting energy usage. Lighting accounts for 14 percent of U.S. electricity use.
