graphene rectenna turns radio waves and light into DC electricity. make silicon carbide with activated charcoal and quartz sand. heat to 2500 celcius in electric arc furnace.

reheat to vaporize outer layer and expose graphene.

We demonstrate a new thin-film graphene diode called a geometric diode that relies on geometric asymmetry to provide rectification at 28 THz. The geometric diode is coupled to an optical antenna to form a rectenna that rectifies incoming radiation. This is the first reported graphene-based antenna-coupled diode working at 28 THz, and potentially at optical frequencies.
