It seems crazy,” Princeton physicist Chris Chyba remarked, reflecting on the device that now sits at the center of a debate ...

The device appeared to violate the conclusion that any conductor at rest with respect to Earth’s surface cannot generate power from its magnetic field,” Princeton’s Christopher Chyba added in a press ...

But since the 1800s, scientists have tried and failed to make this happen using Earth’s rotation alone ... from heat gradients and background electromagnetic noise. Scaling the system to ...

In 1971, the Russian physicist Yakov Zel’dovich predicted that electromagnetic waves scattered by a rotating metallic cylinder should be amplified by gaining mechanical rotational energy from the ...

The setup created the special conditions where the cylinder’s rotation could amplify electromagnetic waves. They didn’t stop there. By adding a resonant circuit—a kind of electromagnetic ...
