Scientists have long proposed that solar electricity generation in space could be an integral component of the world’s carbon-free future. In the 1970s, a U.S. Navy experiment showed that it might be ...

In what it describes as the most significant demonstration of its kind in half a century, the US Naval Research Laboratory (NRL) beamed 1.6 kW of power over a kilometer (3,280 ft) using a microwave ...

Imagine a future when our technology functions not by using energy gained through the burning of fuel, the use of batteries, or the stretching of miles of cables. A future when energy can be beamed ...

Microwave plasma dynamics encompasses the study of ionised gases generated by high frequency electromagnetic fields and their complex interactions with the surrounding medium. At the heart of this ...

Three years ago, Sanjay Vijendran's colleague told him about a scheme that seemed straight out of science fiction: beaming energy from solar panels in space down to the Earth. "The whole idea was new ...
