Electrostatic motors are now common in MEMS applications, but researchers at the University of Wisconsin and spinoff C-Motive Technologies have brought macroscale electrostatic motors back. [via ...

What if the very principles that have powered industry for over a century were suddenly turned on their head? For decades, electromagnetic motors—reliant on copper windings and rare earth magnets—have ...

When we hear about moving objects with electricity, most of us imagine a "pulling force." Positive and negative charges attract each other, drawing objects together. It is natural to think that this ...

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly ...
