No, but sis in law's son made up an outdoor cooker with lotsa mirrors. A fun
thing, no good in the rain, or at night, or when cloudy.

Water has been used very successfully on large projects- a skyscraper beside
Sydney Harbour uses the ocean water as a heat store. Yes worth the cost but
not a homepower option as few of us live near a body of water. For a 
ouseboat
family, very promising I guess.
THe big problem for homepower application, would be to resist the corrosion
when the condenser is water immersed. Standard condensers are fragile, with
really thin metal tubing. For water immersion, special alloys and/ or thick
pipe necessary.
