Inhabitat has a post on Toyota's latest hybrid vehicle design - Toyota's New Hybrid MR2 Revealed!. The Toyota MR2 sportscar is hitting the road, remade from its older version into a Prius-inspired hybrid vehicle. The new MR2 will draw inspiration (and technology) from the iconic Toyota Prius, with the goal of creating a mass market hybrid sportscar that is as fun to drive as it is green. Toyota's development of the MR2 is not to one-up the Tesla Roadster, but rather to create a car that can do a reasonable 0-60mph in seven seconds and get an incredible 60mpg. We are all familiar with Toyota's efforts to create a mass market electric vehicle. The Prius, after all, is the best known green car on the market. So looking to capitalize on such technology while creating a sportier, much more dynamic looking vehicle has great implications for both a consumer market and the corporation's innovation.

A thermal engineer is a professional who specializes in a complex field of engineering that focuses on thermodynamics, heat transfer, mass transfer, and fluid mechanics.

Jamais Cascio has a post on the widespread availability of DIY solar panels in the US - Living in the Green Future. Popped into Costco today to pick up a couple of items, and what did I see? Just in case you can't read that too well, it's a 60W solar panel setup, with inverter (allowing it to power 110V devices), junction box to hook the four panels together, cabling, and frame... for under $300. Stacked like tires at Costco. This is a beautiful example of why I talk about the banality of the future. Cheap solar power systems readily available to the unwashed masses was once something out of science fiction; today, it barely elicits a glance from shoppers stocking up on cases of pickles and TVs by the six-pack.

Australia is the dryest nation on earth, always was always will be, the trouble is Global warming is making the situation worse and rainfall is reducing in a disturbing pattern. For two centuries since European settlement the States have fought over 'Water-Right's' and the use of water to the detriment of the environment and ultimately to the sustainability of everyone residing here. The Murray-Darling Basin is 3,370km long, drains one-seventh of the Australian land mass, and is currently by far the most significant agricultural area in Australia. The name of the basin is derived from its two major rivers, the Murray River and the Darling River.

Ikea's innovation was to cut storage and transport costs with flat-pack furniture, and at the same time bring some simple and attractive design to mass manufacturing. Now the Swedish company plans to bring this buying power to alternative energy. Johan Stenebo of Ikea spinoff company Greentech will invest $75 million in solar companies and wants the retail giant to start selling the products in Ikea store in two to four years.

Researchers at the U.S. Department of Energy's Idaho National Laboratory say they have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. They say this technology is the first step toward a solar energy collector that could be mass-produced on flexible materials.

Light-emitting diodes (LEDs) are better than compact fluorescent bulbs--LEDs use less energy, last longer, and contain no toxic mercury--but for general white-light illumination, they're still far too expensive for mass adoption. Now, researchers at Purdue University have taken a step toward making white LEDs with cheaper materials.

A four-square-kilometre chunk has broken off Ward Hunt Ice Shelf - the largest remaining ice shelf in the Arctic - threatening the future of the giant frozen mass that northern explorers have used for years as the starting point for their treks. Scientists say the break, the largest on record since 2005, is the latest indication that climate change is forcing the drastic reshaping of the Arctic coastline, where 9,000 square kilometres of ice have been whittled down to less than 1,000 over the past century, and are only showing signs of decreasing further.

The jury is still out on whether hydrogen will ultimately be our environmental savior, replacing the fossil fuels responsible for global warming and various nagging forms of pollution. Two main hurdles stand in the way of mass production and widespread consumer adoption of hydrogen "fuel cell" vehicles: the still high cost of producing fuel cells, and the lack of a hydrogen refueling network.

In a significant milestone in the deployment of flexible, printed photovoltaics, Konarka, a solar-cell startup based in Lowell, MA, has opened a commercial-scale factory, with the capacity to produce enough organic solar cells every year to generate one gigawatt of electricity, the equivalent of a large nuclear reactor. Organic solar cells could cut the cost of solar power by making use of inexpensive organic polymers rather than the expensive crystalline silicon used in most solar cells. What's more, the polymers can be processed using low-cost equipment such as ink-jet printers or coating equipment employed to make photographic film, which reduces both capital and manufacturing costs compared with conventional solar-cell manufacturing.

The 25-percent-by-2025 renewable electricity standard bill introduced today by Rep. Edward Markey (D-Mass.) and Rep. Todd Platts (R-Pa.) would boost renewable energy generation by 135 percent above and beyond current policies between now and 2025, according to the Union of Concerned Scientists' preliminary analysis of the legislation. "This electrifying standard would provide a smart, proven, cost-effective strategy to ramp up our clean energy use, create tens of thousands of jobs, and lower consumer utility bills," said Alan Nogee, UCS Clean Energy Program director. "The clean energy tax incentives that Congress is finalizing will get us moving in the right direction in the near term, and the renewable energy standard makes sure we stay on that path for the foreseeable future."

The Alliance to Save Energy hailed new Energy Efficiency Resource Standard (EERS) legislation, introduced today by Rep. Edward Markey (D-Mass.), as effective federal policy that would reduce consumers' energy use and therefore costs; cut global warming pollution; and supplant the need for new power plants to meet rising energy demand. The Save American Energy Act would cut electricity and natural gas demand and, in combination with another newly introduced Markey bill creating a Renewable Electricity Standard (RES), create more than a half million jobs and save U.S. consumers more than $180 billion, according to Markey's office.

DOVER, Mass. - On a recent sunny afternoon Bob Loebelenz pauses to gaze 72 feet into the air at the spinning blades of his wind turbine, a small "clean, free electricity" smile creasing the corners of his mouth. While giant wind turbines that supply power to utilities sprout along ridgelines across the United States, far smaller residential wind generators, like the one Mr. Loebelenz erected in 2003 to power his suburban Boston home, are still unusual in densely populated places.

The sun blasts Earth with enough energy in one hour-4.3 x 1020 joules-to provide all of humanity's energy needs for a year (4.1 x 1020 joules), according to physicist Steven Chu, director of Lawrence Berkeley National Laboratory. The question is how to most effectively harness it. Thin-film solar cells may be the answer: One recently converted 19.9 percent of the sunlight that hit it into electricity, surpassing the amount converted into power by mass-produced traditional silicon photovoltaics and offering the potential to unleash this renewable energy source.

What do you do if you build a wind farm smack dab in the middle of a major bird migration route, and want to avert the anger of conservationists? Put up a radar system that's designed to shut down the entire thing when it detects a mass of birds on the way. That's what's been done at the 202 MW Peñascal Wind Farm in Texas: System Detects Birds Approaching Four Miles Away The system uses radar originally developed for NASA and the US Air Force to detect birds as far as four miles away, The Guardian reports. When it picks up the approaching birds, it analyzes the existing weather conditions and determines in real time whether those birds are in danger of flying into the blades. The system then automatically restarts the turbines when the birds have passed.
