the incandescent light bulb is looked down upon. it is said that 95% of the energy it used is wasted as heat.

so why do we look at it as a poor method of lighting, instead of an incredibly efficient source of heat?

most heaters in the us are only 80-90% efficient. instead of oil burners and coal furnaces, why are we not employing batteries of light bulbs in out basements?

The incandescent light bulb works on the same principle as an electric heater or a toaster, just with a really fine really hot filament inside an inert atmosphere to keep it from burning. Its not a very efficient heater either... though they are great when you need both heat and light.

exactly, they are not a very efficient heater. my post was sort of tongue in cheek about it. its just hearing all this green talk bullshit gets old.

95% inefficient? it seems they just pull these numbers out of their asses. but going by their numbers, a 95% efficient heating source would be phenomenal.

its just eating on me today. i think its the hypocrisy of the whole green movement.

LONG LIVE THE LIGHT BULB!!!!

On farms they are often used as heat, from warming chicks to keeping water bowls from freezing.

People use them in the underground pump house as well.
