This is so cool, thanks for sharing! If I had a yard/space to build one of these, I would totally try rigging one up to drive a little heat engine.

Thanks for your nice comment.

Yes it's definitely fun to build one and use that free energy from the sun.

I was particularly happy to eat my first solar gratin :-)

Hmmm. A solar espresso machine, with the sun heating the brew water and also a boiler to drive both the steam wand and the steam engine that runs the espresso pump!

(I'm mostly looking for an excuse here to stay in bed on bad weather days...)
