A wild idea has been proposed to generate electric power from Earth’s rotation with the help of magnetic fields. A new research has presented experimental evidence confirming a previously theorized ...

Engineers at the University of Delaware have uncovered a way to bridge magnetism and electricity through magnons—tiny waves ...

In a metal like copper, however, the outer electrons swim around freely and are shared by all the atoms. That’s why ...

Turning red-hot lava from an active volcano into electricity would be dangerous and unreliable. Volcanoes don’t erupt on predictable schedules, and lava cools too quickly. But many countries, ...
