Honestly, reading through his stuff is almost depressing. But as long as he sticks to the physics stuff, it's pretty hard to argue - all the math and sources are there. The planned proposal claims that they can use some nifty beamforming to get good microwave transmission. It appears that the proposed technology will reduce the weight to diameter size of the transmitter, but Do The Math's calculations should still more or less be in the right magnitude.
