Saw a blimp today, right in my neighborhood, flying rather erratically, was actually kind of worried it was in some sort of trouble.
Realized the surface area of those things is huge relative to their weight, of course, and it would be quite easy to make them, or cover them, with some of the new light weight films that turn solar energy into power. I would think the surface area is so large that it could easily make enough power to run the motors that propel the thing.
You could have hundreds of these over a big city, as long as (I suppose) it wasn't too windy.
