there are a few examples of modern day concentrated solar power outfits on the good old wikipedia.

looks like the first patent for a solar steam engine was given in 1886 while the first one was built in 1866.

I can't imagine that obtaining the materials involved is ecologically benign, but I suspect that these might beat photovoltaics when considering negative impacts.

This is a cool concept. I have recently been looking at parabolic mirror boilers on Youtube, some of them are totally DIY and made with recycled/salvage material. One fellow in Colorado made a large parabolic array that runs a 12kw generator.

There are no more "hours", it's centi-days. They say it's better, but this tiny ad says it's stupid:
