Re: [biofuel] Fwd: thermophotovoltaic technology
few fuel cells run at that temperature. none of the more popular ones. It's also my understanding it's infrared light, not heat, that triggers these babies.

Re: [biofuel] Fwd: thermophotovoltaic technology
I have spoken with Jason B. Keyes <[EMAIL PROTECTED]>of http://www.jxcrystals.com/ that makes the "Midnight sun" stove. These are infrared pv, and need infrared light, not just heat.

[biofuel] Fwd: thermophotovoltaic technology
Hello fellow biofuelers, The following message was posted on another email list. I do not have this magazine yet. Sounds like this technology might be a god-send if the cost is tolerable. Maybe wrap these cells around IC engines, put them in solar collectors, etc? Sheesh, per the numbers given, one square meter of cells would generate 50 kW of electricity! Too good to be true??? >>> An article in the June issue of Popular Science told about some new technology about to hit the market. These are something like solar cells in that they collect one form of energy and convert it into useable electricity. But these are designed to absorb heat from another source and convert the heat into electricity. They are designing home heating furnaces that have these TPV cells lined around the internal combustion chamber to absorb the heat and convert it into enough electricity. A regular solar cell makes one milliwatt per square centimeter. the TPV cell makes 5 watts of power per square centimeter. One model heating unit already on the market makes enough power to run its own fan, recharge storage batteries, all the while supplying enough heat for the house. The next generation units are predicted to generate enough electricity while heating the home to power the rest of the house's needs and put juice back into the power grid during low energy need times. If they can figure out how to do the same with airconditioning compressors(which also put out a lot of heat), dryers, and stove/ovens, you Californians may not need any new power plants after all :0) <<< -- ...Warren Rekow Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html To unsubscribe, send an email to: [EMAIL PROTECTED] Your use of Yahoo!
