The microwave transmitters are still a big What-If? You can pretty easily argue for space based solar power, but getting it back down is still a huge question.

The microwave transmitters are still a big What-If? You can pretty easily argue for space based solar power, but getting it back down is still a huge question. A big pushback against wind is "what about the birds?" which is a dubious argument at best. The microwave beam probably wouldn't be the death laser you would imagine, but it would still end up with significant pushback from those susceptible to petrochem propaganda.
