In-space power generation system based on floating electrodynamic tethers with low work function.
Spanish university developed an in-space power generation system that transforms the orbital energy into power for on-board use. Thanks to the geomagnetic field and the relative motion with respect to the ambient plasma of 2 floating electrodynamic tethers or set of tethers, connected to a battery or impedance, a steady current is generated. Tether segments capture electrons from plasma and emit them through the thermionic and photoelectric effects. Looking for financial and license agreements.
