Is a Fresnel lens from an overhead projector enough to power a solar stove?
I have seen big TV fresnel lenses being used for solar stoves but however I have not seen any videos on using a fresnel lens being powered by an overhead projector to power a solar stove. Would the overhead lens be big enough to handle it? Any info & instructions would be a big help.

NO. The lamp from the projector is a few hundred watts in output power, probably less than 100 watts in actual thermal energy. The lens doesn't multiply this, just focuses it. 100 watts is not enough to use as a stove, which takes thousands of watts of power.
