Summary

The talk proposes a concept for powering commercial aircraft via microwave energy beamed from large solar farms on the ground. The speaker, Christian Claudel, argues that current alternatives like sustainable aviation fuels and electrofuels are not scalable or economically viable. He outlines the technical requirements: kilometer-scale solar farms with integrated phased array antennas, operating in the radiative near field to focus energy on aircraft. The system would provide power to aircraft in flight, enabling hybrid-electric propulsion with reduced fuel consumption. He discusses efficiency, safety, and economic estimates, comparing costs to jet fuel and other alternatives. He also addresses potential synergies with space-based solar power and reflector satellites. The talk includes a Q&A session covering topics like long-distance flights over oceans and safety for wildlife.
