Ok, this guy is pretty amazing! The bellow project is interesting in that it’s surprising the amount of heat generated from a lens focused on sunlight. Watching this made me wonder why solar panels aren’t more efficient at capturing all of the awesome power afforded to us by the Sun… maybe we’re going about it the wrong way. Anyway, you really should check out some of Grant’s other projects, i.e. how to start a fire with a water bottle, or if you drank all your water, check out how to light a survival fire with urine.
