electricity for free ELECTRODYNAMIC TETHERS!

NASA has a technology that creates free electricity from interacting with space and the Earth's electromagnetic field.  The space around earth is not a void but a weak plasma full of electrically charged particles (protons,cosmic rays,electrons) by having a large conductor in earth orbit the speed of it's travel through Earth's magnetic field and the space radiation give it huge electrical energy!
These can be deployed from orbiting probes to the ground to give earth free electricity!  They can also be used for space propulsion!
