MagCap Engineering, a magnetics manufacturer, and Gordon W. Wadle, an inventor, have
patented a method to capture energy from plants and turn it into DC power.
Currently (so to speak), the
system works using rods (one in a tree and one in the ground) and special circuitry developed by MagCap. There is
enough electricity produced by the system (2.1 volts) to keep a battery fully charged. The company is looking to
increase the output to 12 volts and one amp, enough to charge batteries for hybrid cars and EVs.
MagCap and
Wadle have contacted investors to finance the technology.
