Next-gen Prius now official, uses solar panels to keep car cool
The very shoe-like 2010 Toyota Prius has made its official debut at this week's Detroit Auto Show. The company estimates it'll have a 50 MPG rating -- up from 46 MPG in the previous model -- and there's a bigger, 1.8-liter four-cylinder engine for improved highway mileage. In addition to Power and Eco driving modes, EV Drive will let you run on battery alone for about a mile, which if nothing else should provide a little extra push for getting to the gas station when you've held off for too long. One of the coolest (literally) new features is the optional solar panels in the moonroof that will generate power for circulating air and keeping the interior temperature from going too high. If that's not enough, there's a remote-controlled A/C system that can run on battery alone and lets you set the temperature before you get in.

Inexpensive solar panels nearly ready for commercialization
We've been inching closer to low(er) cost solar panels (for the mainstream public to enjoy) for some time now, and apparently, AVA Solar Inc. is just about ready to start cranking out units that "will cost less than $1-per watt by the end of next year." The technology was reportedly developed by Colorado State University's Professor W.S. Sampath, and production is slated to begin soon in a "200-megawatt factory" that could employ some 500 individuals. Of note, it was said that the "cost to the consumer could be as low as $2 per watt," but even that figure purportedly rings up at about half the cost of current options.[Via Slashdot, image courtesy of CSU]
Pink solar cells provide green power on the cheap
The race to build a cheaper solar cell continues to produce results, as researchers at Ohio State have developed a nanotech solar cell with a unique pink color that they say will one day be able to produce as much power as traditional silicon cells for a quarter of the cost. The dye-sensitive solar cells, or DSSCs, get their pink color from a mixture of ruthenium and either titanium or zinc oxide particles that absorb sunlight, while nanowires link the particles to provide power transfer. So far the team have gotten the cells to produce half as much power as traditional cells, but the next step is to start using nanowire "trees" to improve efficiency to equal or surpass those levels. No word on when we'll see this tech hit the market, but surely the prospect of a hot pink solar Cadillac isn't too far off.[Photo is of an unrelated DSSC concept from New Zealand]
Sharp solar panel system installed at AT&T Park
While you were busy watching Vladimir Guerrero take home the Home Run Derby crown two nights ago (not to mention the All-Star game last night), you may not have been aware that AT&T Park was feeding uber-clean energy back into the grid serving PG&E's customers throughout northern and central California. Sure enough, the home of the San Francisco Giants is now also home to 590 Sharp solar panels located in three separate areas of the stadium, which combine to generate some 120-kilowatts of electricity. The size of the entire array is reportedly "equivalent to approximately 40 residential solar systems," and while this system won't conjure up as much power as the CIS Solar Tower, it will certainly make good use of the ballpark during the off-season.[Via EETimes image courtesy of MatrixCS]
New Zealand peeps imitate plants to do solar on the cheap
Obviously, scientists didn't exactly originate the idea of harvesting energy from the sun when they started slapping together solar cells -- plants have been up on this whole photosynthesis mojo for a good long while. Now some researchers at Massey University in New Zealand have developed a range of synthetic dyes from organic compounds that closely mimic the light harvesting that goes on in nature. Other scientists have been pursuing similar solar techniques, but there's a major difficulty in getting the dyes to pass the energy on for actual use. After 10 years of research, the Massey scientists claim to have "the most efficient porphyrin dye in the world." Benefits of the dyes over traditional silicon-based solar panels include the ability to operate in low light, 10x cheaper production, and flexible application -- starting with canvassing roofs, walls and windows, but eventually moving on to wearable items that can charge your electronics stash. A working prototype for "real applications" should be ready in a couple years.[Via The Raw Feed]
