THE EDGE: Terahertz Wave Harvesting

Terahertz wave energy harvesting can now deliver free energy from waves that are pervasive in our daily lives. People with high COVID virus temperatures emit them.

Anything that registers a temperature, including our own bodies and the inanimate objects around us, including Wi-Fi signals, also emits terahertz waves —electromagnetic waves with a frequencies somewhere between microwaves and infrared light. These high-frequency radiation waves are known as "T-rays". Unlike solar and wind power, you can harvest T-Rays 24-7, rain or shine.

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone. So you get free cell phone charging anywhere. MIT, Stanford, Raytheon, etc. scientists have already built working desktop systems.

You can use quantum mechanical, or atomic behaviors, of  carbon material graphene, combined with other materials (boron, nitrogen, etc.) to force in graphene to skew their motion toward a common direction. We are looking at this to amplify our electric propulsion systems but it has wonderful side-effects for energy harvesting. Any incoming ambient terahertz waves "shuttle" graphene's electrons, like so many tiny air traffic controllers, to flow through the material in a single direction, as a direct current. Exciting new energy and propulsion products will be coming from this!
