...and not for the obvious reasons of drunkenness and sharp edges. We were having lunch in the kitchen today when I noticed a puff of smoke rising from the table. The water soaking in a wineglass in the sun was concentrating sunlight onto a pinpoint on the table.
Now I know why there are new burn marks on the table; I had thought they were maybe from the crockpot, which we've used lately after not having used it for years.
B. did a bunch of experiments with different materials and different amounts of water and measured the temp with the instand-read thermometer. (He's such a scientist!) I think 176 deg F was the high.
So obviously there is something to these solar cookers. But could we burn our house down?
