For reliable, uninterruptible power at remote facilities that they don't
need to refuel and only need to ship in a rectenna for (as opposed to a
heavier generator)?  Yeah, they'd pay that price.

You know how to do it.  That's why I'm asking you.

Or, same size spot on the ground, and just use a much lower power density.

No, the point is to get you or Paul to sell them on the idea.  You
(collectively) have the data necessary to do this sales job.  I may have
