There are Stirling engines which will run on the heat of your hand, although they are a little harder t...

Also, how much energy am I wasting for powering devices when not in use ? I wanted to check it out and decided to build a device capable to detect stand-by mode of my electronic devices and start metering energy used. All thi...

It's a permanent magnet alternator, generating 3 phase ac, rectified to dc, and fed to a charge controller. The magnets spin with the wind, the coils are fixed, so no brushes or slip rings necessary.

Here's an Instructable to make a simple, cheap, and energy efficient air conditioner with basic materials, and should cost less than $5. How it works is evaporating water in the A/C (air-conditioner) pulls heat away, making the inside cold. The fan sucks air through the A/C, making the air cold. T...
