Millenium Solar, an Israeli PVT (photovoltaic thermal) company
is preparing to build a 20 megawatt power plant in South Korea. PVT
technology basically just combines to two main applications of solar
power (electricity generation, and water heating) to make them both
more poweful. As silicon photovoltaics heat up under the sun, they
dramatically lose eficiency. But if there's a built in hot water
heating function, the hot water carries away the heat and cools the
solar cell, making it more efficient.
PVT systems have been implemented in small scale projects...houses, hospitals, etc. But there has never been a full-scale power generation plant created using PVT. The increased efficiency means that PVT can sell it's electricity for as little as 10 cents a KWh and still make a profit. South Korea is, in fact, subsidizing the plant, and will be purchasing the power at 60 cents a KWh, which sounds, to me, a little bit like taking advantage of a solar-friendly government.

Nice to see that the innovators have finally come out in force. Hot water, and electricity at the same time!

In recent years, Audi has been making big strides in terms of improving its recognition in the marketplace as a premium European automaker. A key component to the brand's effort is the A6. Now in its third generation, this midsize sedan and wagon (known as the Avant) boasts V6 or V8 power, the Quattro all-wheel-drive system and class-leading interior quality. Plus, with a starting price of less than $45,000, the V6-powered 2008 A6 dramatically undercuts models from BMW and Mercedes-Benz and easily matches up to competitors from Japan.
