Stirling Engines and Solar Power
I have been saying for a long time that the solution to humanities energy needs is not going to be one single technology. Rather a constellation of technologies that all complement each other, solar, wind, tidal, thermal, nuclear, etc. Well a version of solar power I have been watching for some time is looking as if its going to come to the commercial market soon. It works very differently than traditional photovoltaics. It uses a Stirling engine and a solar collector to pump heat into the engine and from there a generator is turned producing electricity. Based upon a 1000 MW power plant the cost per kWh would be about 6 cents.
Given that the average cost of power so far in 2005 for residential users is 8.49 cents per kWh I think we are now ready for solar power.
Additionally technology like this must become our mainstay for power generation for a variety of reasons…
