Normal motors are driven by electromagnetic forces. This 3D printed electrostatic motor created by lasersaber in the video below needs no batteries, mains supply or solar cells. Compared to normal motors, electrostatic motors are extremely light in weight and use inexpensive materials.

Electrostatic motor can be turned by the kind of electricity generated by wearing nylon clothes. It is a little-known fact that there is a tiny charge flowing between the sky and the surface of the earth. This sort of motor could be run from atmospheric static with a high enough antenna. A tall antenna is insulated from the earth and is used to intercept the vertical current and develop a high voltage to drive the motor.

Unlike most electrostatic motors, this 3D printed electrostatic motor actually has some high torque. The motor was 3D printed out except for the drive shaft, bearings, and aluminum tubes. Watch the awesome project and how 3D printing helps with lasersaber's mechanical exploration below:

If you want to replicate this motor, you can find link to parts and .stl 3D files in a .zip from lasersaber's website.
