An aircraft was flown using microwave energy 20 years ago, but these were the first known demonstrations of beamed light energy to fly an airplane.

My challenge to them would be to power a satellite orbiting the Earth by laser, or by microwave. This would test the efficiency of power transmission through the atmosphere & ionosphere at various angles and times-of-day, perhaps even model the influence of solar radiation and RF interference.
