10 Uncommon Ways To Generate Electricity For Your Homestead
The motor – old hard drive motors are designed to spin heavy metal disks for hours on end at very high speeds. If you can get a good running motor, you could find a way to reverse it so that it will put electricity out instead of use it. The metal plates – heavier plates are perfect for Tesla Turbines that will spin at higher speeds.
