[AZ-Observing] Re: Going Green out at the observing field

Jimmy, that's amazing that you can boil water with something that size.
Does it use a concentration system to get that hot?  I ask, because my
attempt to boil water with the Sun fell a few degrees short of the goal.  To
see my DIY attempt at solar cooking, check out:

At least it worked out well for cooking hotdogs.  :)  And how about that
cool image showing the rays of light getting concentrated?
