Re: Home Energy Savings
There are designs out there for a device that uses heat itself (a form of waste energy) and converts it back into electricity. It's called a thermoacoustic prime mover, and is very cheap and simple to build. There are designs all over the net for different versions of the same thing, but they all do the same thing. It can also be adapted for three different uses. If you heat it up, it generates sound which can be converted into electricity via a piezoelectric device, which you already have in your own home in the for of a smoke detector speaker. If you put sound into it via a loudspeaker, or any sound wave generator for that matter, you can transfer heat from one place to another (with a few devices added) turning it into a heat pump. Finaly, you can use one to convert heat into sound to cool something off, such as you see in some refrigerators (not all refrigerators use freon). Essentialy, you can lower your power bill by, instead of using the airconditioner, sucking heat out of the air, turning it into usable electricity, and using that electricity to power other things in your house.
