What is the theoretical ground-based solution proposed to bypass the onboard power mass problem for electric launch vehicles?

Answer

Beaming microwave or laser energy from ground stations to a receiver on the rocket.

This concept shifts the weight penalty associated with generating massive amounts of electricity away from the vehicle structure and onto large, stationary power stations located on the ground.
