My wife found this on one of her old house blogs. Really cool idea.

I added this to the list. Please continue....that are not on the hearth approved list.
I don't care how they make my light, I just want lumens per watt, CRI and cheap.
But I don't think this thing has a chance to catch LEDs.
The article is also misleading re the performance of modern LED lights.
The next project of these MIT researchers is Swiss watches that use new high tech gears made out of coal. Rumor is that coal is abundant and the market for coal has collapsed due to the demise of incandescent lighting.
You missed my point, begreen! It's 100% efficient, with zero waste during heating season for everyone, not just me. My local clime is 5600 heating degree days, and 800 cooling degree days, so one might say the average annual efficiency is really 88%. Either way, I don't understand how LEDs are cutting down on waste, when we consider the increased manufacturing costs, given that the national population average climate is probably not far from my own.Multiply your home times millions. It's not about heating the house, it's about increasing efficiency and reducing waste on all fronts. Same reason you are now burning more efficient stoves. Conservation is our best resource and the cheapest path to energy self-sufficiency we have.
If you research this issue you will find that the life cycle cost of LEDs (manufacturing, transportation, and energy from using) is much lower than incandescent bulbs.Either way, I don't understand how LEDs are cutting down on waste, when we consider the increased manufacturing costs, given that the national population average climate is probably not far from my own.
I think it's efficient to use but not very when considering generation not to mention transmission. More efficient overall to heat with oil/gas (wood!) and not with a bunch of tiny electric heaters . It would be cost prohibitive for me as well since our price per kw/hr are high.You missed my point, begreen! It's 100% efficient, with zero waste during heating season for everyone, not just me.

And, yes, I have had a home heated with electric. Worked out great for me, since I was only heating the rooms in which I was sitting at any time, so it ended up being very inexpensive and efficient for me. Sort of like the lights also only heating the room in which you have them on.
Thank you! I should have expected if there were a good answer, it would come from you, woodgeek.With modern heat pumps in our climate, >200% average efficiency is easy, 250% is attainable. With geo, you can get over 300%. So 100% IS practically 'wasteful'.
