Why not use microwave transmission of power. Easy to control the "beam",
relatively easy to construct an array of "rectennas" (dipoles with a bridge
rectifier). Lots of references to check out such as early works on
Satellite Power Systems (array of solar cells, beaming power back down to
earth, etc.) There was a microwave powered helicopter built about 20-30
years ago.

Start with a microwave oven magnetron as a power source, about a half
kilowatt at 2450 MHz (or 12 cm wave length). Build a suitable horn as a
transmitting antenna with narrow beam width. the rest is an exercise for
the reader.
