The code name, Space Beast, was one they came up with in the wee hours of the night. Tyler Lyon, Daniel Winegar and Chad Thornley were overtired and giddy as they tackled a science fair project. Their idea: Eliminate the use of Freon in automobile air-conditioning systems by relying on the Peltier effect – of course. Link.
I’m not sure what “economical” in the subject line means – peltier junctions are far less energy efficient than compressing and expanding a working fluid (the normal sort of air conditioner).
I also don’t understand the word “invent” – peltier cooling (even air conditioning) is nothing new.
I also don’t understand “eliminate the use of freon” – Freon has not been used in car airconditers for years – what is now used is the replacement HFC-134a.
Other than that… :)
