Then there was my previously mention solar-satellite-dish-chair-burner [tm] Large: http://g3.img-dpreview.com/3F7339A620EB4831BDD333E8DF455769.jpg Small: http://g1.img-dpreview.com/25740F9934B4450CACE1DF2F6BCE0C63.jpg Satellite dish was dual re-purposed. - Trial solar concentrator with Al / Mylar foil - Cellphone range extender. Was used in latter mode t night sitting in old chair on back porch. Used to get reliable coverage as phone coverage in our area was in a "shadow" from local ridge. Dish left sitting on chair arm. Sun rose. Low angle of morning sun produced result which seemed infeasible [tm] due to orientation. Could easily have burned house down! :-(.
