We can do the same for these

It might be a good idea.


  1. Could the balloons be easily positioned up there with no wind or asteroid problems?


  1. Some shade would be welcome in Phoenix but in other places farmers may complain about the shadows cast by the balloons.

  2. Could the balloon lift high voltage lines to transmit the power to earth?

Dear Bret Cahill:

You'd have more or less constant wind. Asteroids would be slightly less in frequency, but (slightly) higher in impact speed.

How about Seattle? It is cloudy there most days... they might never know...

Not economically.

Ground-situated solar farms are safer. Even if we don't get shade out of it.
