the back deck might be flatter and less cluttered than the dashboard. aim the
car north, put a towel on the back deck, then a 9x16" rectangular pan (1 ft^2)
with about 1" of brownie dough containing a pint of water on the towel, with a
glass or transparent microwavable plastic cover, and a more or less vertical
folding foil and cardboard reflector with ew wings to the north of the pan to
concentrate 4 suns (1,200 btu/hour) onto the pan. if the car is 100 f inside,
the sun will try to heat the dough until 1,200 = (t-100)1ft^2/r1, ie to a
temperature t = 100 + 1200/1 = 1300 f. but the water has to boil away first
(a few pinholes in the cover might let the water escape), which takes about
1000 btu/pound, so the brownies might be done in 1000/1200 = 0.83 hours.
