Create a flying machine that uses electrostatic repulsion and attraction

Understanding
Guided Beta radiation or electron guns could be aimed at the repulsion target to charge it. Once charged it could be repelled against. If the voltages achieved are very large then the forces will be large. If the areas of the repulsion force a very large then the force will decay more gradually over longer distances (or greater altitudes). Electrostatic repulsion would be very energy efficient. The losses would be due to grounding and discharge into the atmosphere. This would be less of a problem on the moon or on planets or moons with thin atmospheres.
