Reliably generating controlled miniature rotations has long been a challenge: Chemical propulsion systems wear out, and ...

Scientists have discovered a surprisingly simple way to make tiny objects spin without using electricity, magnets, chemicals ...

There have been some laboratory experiments and theoretical work done to validate aspects of the plasma magnet propulsion concept. The Plasma Magnet is a wind drag device invented almost twenty years ...

The “caterpillar drive” in The Hunt for Red October allowed the sub to travel virtually undetected through the ocean, but real examples of magnetohydrodynamic drives (MHDs) are rare. The US Navy’s ...
