Excerpt:
"First invented by Robert Stirling in 1816, the engines use a heat source to warm gas, which expands and is pushed into another chamber. When the gas cools and contracts, it flows back. The expansion and contraction pushes a piston, which in turn produces electricity."http://www.scientificamerican.com/article.cfm?id=are-engines-the-future-of-solar...
This technology does not require any water, only a bit for cleaning the mirrors and is much more efficient at converting sunlight than photovoltaic cells.
Maintenance and cost seem to be the problem though.
So much time, money and above all natural resources our government waisted and sacrificed because of greed and corruption.
"First invented in 1816...", almost two hundred years ago, it makes you think.
