grab heat from incandescent light bulb

 Hi,

I have another question about grabbing heat.  I noticed that
incandescent light bulbs tend to generate a lot of heat a few inches
from the ceiling, especially if it's a small area ceiling.  I have
been trying to think up a way to gather  that heat and perhaps down
some kind of pipe with the top that has an inlet pointed at the light
source and a blower/outlets at the bottom dispersing the warm air
across the floor.  Maybe the light bulb can generate enough solar
power for a very simple blower to run off of it.

Thanks,

Carl

 
Why not switch to lower wattage CFL bulbs and not have so much wasted energy
to heat.  Optimize lights for lighting, not for heating.

If you do want to make use of heat at the ceiling (all heat rises remember),
why not just add a ceiling fan to recirculate the air within the room
regardless of the source.
