KAIST’s newly developed electric vehicle system could be onto something. The vehicle does away with batteries completely and relies on pulling power from a system of cables buried beneath the road. The On Line Electric Vehicle (OLEV) is comprised of electric buses that drive over tracks containing power coils. When a bus crosses the track a boost of electricity is delivered, allowing the vehicle to continue travelling without having to stop and recharge.KAIST’s newly developed electric vehicle system could be onto something.

Rheem Manufacturing Company has announced a groundbreaking association with the Valley Electric Association (VEA) to launch the largest Domestic Solar Water Heating (DSWH) program ever undertaken in the United States.This program offers each member of the VEA, an electrical co-op servicing more than 22,000 meters within Nevada and California, an opportunity to install a Rheem solar water heating system in their residence.
By installing a Rheem SolPak water heating system, participating residents and business owners will achieve significant water and energy savings. It's estimated that members switching from electric or propane water heating systems will save between $250 and $550 annually on water heating. According to the VEA, this program will also help to eliminate 15.4 million pounds of carbon dioxide annually and save $34 million or more, collectively, on energy costs over the next 20 years.
Valley Electric and Rheem, along with Ed Begley Jr., star of HGTV's "Living with Ed," officially kicked off the DSWH program at Valley Electric's 2009 Energy Symposium on Sept. 5, 2009, in Pahrump, Nev.
"We're extremely pleased to have been selected as the exclusive solar supplier for this project, which is a watershed event for energy and water conservation in the U.S.," said Chris Peel, Rheem senior vice president and chief operating officer.
"As the only company that offers innovative air conditioning and water heating products like SolPak, we applaud Valley Electric and its members for taking a proactive and creative approach to sustainability and green living. Together, we're looking forward to providing home and business owners in California and Nevada with the ultimate in comfort, while also doing our part to further conservation efforts."
"In addition to providing affordable solar water heating to nearly 5,000 homes, we anticipate that the program will immediately create over 100 jobs in Nevada and increase capital in the area by approximately $12 million," said Jeff Mahoney, Rheem alternative energy market manager.Rheem Manufacturing Company has announced a groundbreaking association with the Valley... more

SYDNEY scientists have scored gold, helping create the world's most efficient technology for turning sunlight into electricity.
Just as swimmers and runners struggle to shave 10ths of a second off their times, solar cell scientists battle for years to add fractions of a per cent to the efficiency of their creations.
US researchers developed experimental technology that could turn 42.7 per cent of the sunlight received into power - a world record.
By comparison, commercial cells often used in solar modules on Australian roofs convert only about 15 per cent.
The US technology was made of five separate cells, each tuned to draw energy from different parts of the light spectrum. One, for example, was designed to collect energy from the ultraviolet light band, while another, at the other end of the spectrum, was tuned to the far infrared.
By replacing one of the US cells with a new design developed by the Photovoltaic Centre for Excellence at the University of NSW, the technology's efficiency has now been nudged to a record 43 per cent.
The Sydney cell converts 46 per cent of red and near infrared light received into electricity, ''dragging up'' the overall efficiency of the American technology just 0.3 percentage points.
While progress may seem agonisingly slow, ''years of effort went into developing the cell'', the university's photovoltaic centre research director, Martin Green, said.
Although highly experimental, and far too expensive for commercial solar panels, the cell will inevitably inspire other researchers to race to develop even better technology.
snip
Professor Green estimated that by combining hundreds of advanced experimental cells, each tuned to different parts of the spectrum, an efficiency rating of up to 86 per cent was theoretically possible. But, he warned, ''it's not as easy as it sounds''.SYDNEY scientists have scored gold, helping create the world's most efficient... more

The latest Electric Power Monthly Report released by the Energy Information Administration (EIA) shows net U.S. electrical generation from renewable sources (biomass, geothermal, solar, hydro, and wind) reached an all-time high in May of 2009, comprising 13% of the total electrical generation for the month.
Renewable sources for May '09 generated 40,395,000 Megawatt hours (Mwh), 7.7% higher than for May of 2008, and thus far the highest figure ever reported by the EIA.
Total generations for all sources, including fossil and renewable, was down for May of 2009 from the previous year by 4.1%, representing the third-largest percentage decline in national power generation since 1974.
Of the 13% from renewable for May of '09, 9.4% came from conventional hydropower and 3.6% from non-hydro renewables. From that 3.6% of non-hydro, 1.8% came from wind, 1.3% from biomass, 0.4% from geothermal, and 0.3% from solar thermal and photovoltaics (the numbers are rounded). Compared to May of 2008 wind net generation increased by 12.5% (with generation increases in the state of Iowa representing 52.2% of the national increase). Conventional hydro increased by 10.2% from May of 2008, and solar thermal and photovoltaics were up 3.5%.

From Dan Jacobson, Environment California and Brian Hurd of Hands on Solar
Links to petition above and below:
If you live in California and don't know about the organization "Environment California" check it out, its a great organization, Dan Jacobson is tireless.....
"Hello Environment California members,
Over the past several years, I have been teaching photovoltaics (solar electricity) to inner city students. We cover solar technology in depth, how it works and how to install these state-of-the-art electrical systems on our homes and businesses.
Whether I am teaching other teachers or inner city youth, students are in my classes because they get it. Green energy technology is the wave of the future -- and the way to rebuild our economy is to start with clean energy. But we can't create a green economy on wishes alone. Jobs have to be created.
That's why I'm urging Sacramento to triple the amount of clean energy in California. And I'd love your support.
If we triple our goals for clean energy production that will mean utilities will start building more windmills, you'll see more solar panels on schools and government buildings, and you'll see an emerging market for new high-tech green jobs.
How did FDR end the Great Depression? He created jobs.
I teach some of the brightest and most enthusiastic students who want nothing more than to repower this state with green energy. But it takes more than rhetoric. It takes a commitment from our leaders in Sacramento.
It's time to triple our clean energy use. Tell your legislators to act:

Powered only by natural sunlight, an array of nanotubes is able to convert a mixture of carbon dioxide and water vapour into natural gas at unprecedented rates.
Such devices offer a new way to take carbon dioxide from the atmosphere and convert it into fuel or other chemicals to cut the effect of fossil fuel emissions on global climate, says Craig Grimes, from Pennsylvania State University, whose team came up with the device.
Although other research groups have developed methods for converting carbon dioxide into organic compounds like methane, often using titanium-dioxide nanoparticles as catalysts, they have needed ultraviolet light to power the reactions.
The researchers' breakthrough has been to develop a method that works with the wider range of visible frequencies within sunlight.
Enhanced activity
The team found it could enhance the catalytic abilities of titanium dioxide by forming it into nanotubes each around 135 nanometres wide and 40 microns long to increase surface area. Coating the nanotubes with catalytic copper and platinum particles also boosted their activity.
The researchers housed a 2-centimetre-square section of material bristling with the tubes inside a metal chamber with a quartz window. They then pumped in a mixture of carbon dioxide and water vapour and placed it in sunlight for three hours.
The energy provided by the sunlight transformed the carbon dioxide and water vapour into methane and related organic compounds, such as ethane and propane, at rates as high as 160 microlitres an hour per gram of nanotubes. This is 20 times higher than published results achieved using any previous method, but still too low to be immediately practical.
If the reaction is halted early the device produces a mixture of carbon monoxide and hydrogen known as syngas, which can be converted into diesel.
Copper boost
"If you tried to build a commercial system using what we have accomplished to date, you'd go broke," admits Grimes. But he is confident that commercially viable results are possible.
"We are now working on uniformly sensitising the entire nanotube array surface with copper nanoparticles, which should dramatically increase conversion rates," says Grimes, by at least two orders of magnitude for a given area of tubes.
This work suggests a "potentially very exciting" application for titanium-dioxide nanotubes, says Milo Shaffer, a nanotube researcher at Imperial College, London. "The high surface area, small critical dimensions, and open structure [of these nanotubes] apparently provide a relatively high activity," he says.

New Energy Technologies has announced that new tests of the Company's ultra-small solar cells for use in its transparent SolarWindow have demonstrated substantially superior performance over current thin-film and solar photovoltaic technologies at generating electricity from artificial light - an important advantage over conventional solar technologies which are limited by their capacity to function well where exposure to direct sunlight is available.
"One of the biggest issues with today's solar products is their dependency on direct sunlight, which our cells have demonstrated the potential capacity to overcome," explained Mr. Meetesh V. Patel, Esq., President and CEO of New Energy Technologies, Inc.
"We're now actively working to coat these cells onto transparent glass in order to fabricate our SolarWindows, which generate electricity and have the potential to be installed virtually anywhere that either direct sunlight or artificial lighting such as fluorescent systems emit visible light.
In contrast, today's building-integrated solar and photovoltaic products are limited to installation on south-facing surfaces, as is the case with currently-available solar materials tested in these newest experiments."
In a series of new experiments, researchers repeatedly tested New Energy's ultra-small solar cells on a 1"x1" substrate against today's popular solar materials for their capacity to produce electricity under varying artificial light conditions, mimicking the levels of light exposure in homes and commercial offices.
In every case, New Energy's solar cells, the smallest reported organic solar cells of their kind in the world, exponentially outperformed all of the conventional materials tested.
Under normal office lighting conditions, without the benefit of outside natural light from windows, New Energy's ultra-small solar cells produced:
Almost 2-fold greater output power density than monocrystalline silicon, an established commercial solar cell material; More than 8-fold greater output power density than copper-indium-selenide, known for its high optical absorption coefficients and versatile optical and electrical characteristics; and
More than 10-fold greater output power density than flexible thin-film amorphous-silicon, a popular 'second-generation' solar thin-film material.
New Energy's solar cells generate electricity not only from the visible radiation found in sunlight but also by using the visible light found in artificial illumination, such as the fluorescent lighting typically installed in offices and commercial buildings.New Energy Technologies has announced that new tests of the Company's ultra-small... more

I'm ready to see some of this "more and more science" data, and not just hear about it from the right-wing. The truth is that climatologists are the ones that we should be listening to on this issue, and everyone with a chemistry set who call themself a scientist needs to stay out of the debate (including meteorologists). 97% of climatologists agree that global warming is real and humans play a role. Try finding that kind of consensus on any other theories in any other field of science. You are being fed bullshit when you listen to people like Buchanan, and what sickens me is that some of you like the taste.

The next big leap in solar materials will be hard to see. Solar energy firms and building-material suppliers are working together to integrate solar cells into building materials, and one measure of success for these products is how well they blend into the overall building aesthetic.
For now, the market for these building-integrated photovoltaics, or BIPV, is small, and the materials they use are still quite visible. But increasing demand, material innovations, and government incentives could power the industry to wrap buildings in an invisible solar cloak.
This is great. If this technology really takes off people won't be able to use the excuse that the solar panels look bad.The next big leap in solar materials will be hard to see. Solar energy firms and... more

Australia’s Carnegie Corporation expects to soon select a site off the nation’s southwest coast for its next installation of CETO, a system that converts ocean wave energy into clean electricity while also producing zero-emissions desalinated water.
The innovative system relies on a series of buoys harnessed to pumps below the ocean’s surface at depths of 15 to 50 meters. As the buoys rise and fall with each passing wave, they power the pumps and push water through on-shore turbines to produce electricity. The pressure of the incoming water also pushes the water through a membrane that removes salt and other minerals, producing fresh water without the typical desalination plant’s high electricity demands.
Carnegie says the CETO technology (named for the sea monster of the same name in Greek mythology) offers numerous advantages over other wind- and wave-energy systems. The benefits include:
* The reliability of wave energy, which is more predictable than wind energy;
* Zero offshore aesthetic impact, as the wave-driven pumps are moored underwater;
* No interference with marine life or human activities like surfing;
* No offshore electrical components, meaning pump units can last for more than 30 years; and
* A system that uses multiple identical units that are easy to mass-produce and ship anywhere.

At tonight's IREO Renewable Energy Awards at the United Nations, film director and author Josh Tickell will be named a United Nations Goodwill Ambassador and accept an award for his work. What work you say? Well, the trailer embedded above for his film FUEL for one thing. It won the Audience Award for Best Documentary at the Sundance Film Festival in 2008 and is currently making its rounds in theaters (show times). This is the story in a nutshell:
If you want a compelling synopsis of how we got into the mess we're in with our fossil fuel addiction (and a very personal one, Tickell grew up in Louisiana and saw first had petrochemical pollution all the time) and how we just might be able to kick the fossil fuel habit, then FUEL should be high up on your list of must-see films.
The Bush administration's actions pulling the nation into Iraq in the (seldom spoken) name of energy security; the early gung-ho enthusiasm for biofuels (Tickell was an early proponent of vegetable oil biodiesel and you see some of his quest in that area) and the subsequent realization that not all biofuels are exactly environmentally or socially good; and how a balanced and diversified package of renewable energy is the way forward for both the economy and the environment are all covered in a detailed, yet accessible fashion.
Some of this may be review from avid TreeHugger readers, but a refresher course is never a bad thing. And for those of you who have friends and family who are either uninformed when it comes to renewable energy or don't think we have a problem, then make sure you take them to see FUEL.At tonight's IREO Renewable Energy Awards at the United Nations, film director and... more

I help fight to save the world because I am a unity supporter and support environmentalism that doesn't include political created genocide, forcing relocation into government approved complexes, creating wars across the world to achieve the Georgia guide stones guidelines of reducing the worlds population, and I am truly going to stop the war between the environmentalists and the economists.
I have made plans on sustainable crops without GMO, I have made plans on sustainable clean fuels that don't require sacrificing the standards of American citizens, I even made plans on sustainable home generated electricity without requiring the sun, the wind, or the water which can harm salmon.
I am donating to bring my ideas to a reality that the current ways of trying to bill people, tax people, and oppress people for helping the environment does not work and will enslave us to the earth. We need a plan that will bring balance to both the Earth and us and bring a stop to unnecessary loss of American standards.
I donate to help the planet and humanity and fix the growing problems and biased debates.
Thats what will make me a worldwide hero, I will save humanity and planet earth at the same time.
Heres the plans already except I don't have the sustainable farms plans ready yet but are in the making and when they are done it will be published in the 2nd part of this article on current.

Sustainable Fuel systems and economy:
http://www.scribd.com/doc/9940103/Energy-Independent-Fuel-Stations-for-Cars-and-Energy-Independent-Electricity-for-Homes-and-Businesses
and I am also done these things on myyearbook:
130 milliseconds of research purchased
1,308 grains of rice bought
2,106 ounces of CO2 removed
2,106 square feet of rainforest saved
10 calories of food bought
1,224 ounces of clean water bought
1,259 milliseconds of research time purchased
183 words in books written
2 condoms bought
34,826 milliseconds of peacekeeping bought
1 square inch of blanket provided
2,863 milligrams of teddy bear stuffing bought
and so I am helping the environment and trying to keep the peace as well because war pollutes too and can contribute to massive explosions of CO2 more then cars because bombs and weapons may be more powerful the the pollution of a car.
I am saving the environment without CO2 taxes and without loss of civil liberties or Standards of westerners.
Please people do not be fearful and please help me bring real change to environmental issues without extra taxes, without making the poor struggle more then they have during the Bush Administration. Please help me American people by giving me support and telling others about my plans to save America, and the world.
I will bring an end to the bloodshed, biased debates and wars if you follow me the planner of sustainable ideas and sustainable living.
I have more just these plans I'm showing you, I am so smart and knowledgeable I can bring help to the American people and create a new and better society then the fear mongering were in now.I help fight to save the world because I am a unity supporter and support... more
