The solar power you don't hear about
Solar thermal power deserves more attention, due to its lower cost and relative ease of storage |

| Solar thermal power is back! Solar thermal gets less attention than its sexier cousin -- high-tech photovoltaics -- but has two big advantages. First, it is much cheaper than PV. Second, it captures energy in a form that is much easier to store -- heat -- typically with mirrored surfaces that concentrate sunlight onto a receiver that heats a liquid (which is then used to make steam to drive a turbine). Back in the 1980s, Luz International was the sole commercia ... |

| Here's a short but fascinating BBC story about a ginormous (11MW, with plans for expansion) concentrated-solar power plant in Seville, Spain -- the first commercial concentrated-solar plant in Europe. Hundreds of mirrors reflect sunlight at a single point at the top of a tower, where the heat boils water for stream that drives a generator. I'd only quibble with one thing: Is it true that this power is three times more expensive than power from conventional sources ... |
