    I suppose a big one could generate a small amount of electricity, but:

    1. You’d run out of tether pretty quickly
    2. Any wind at all makes retrieval more difficult
    3. You’d be limited to areas with unrestricted airspace, which only exists in very rural areas

      When it reaches the end of the tether, the taut tether pulls a mechanism to open the top and let the hot air out. The mechanism gives it enough weight to come down again. Once it comes down, the top gets shut again (somehow?). A wind powered fan inflates it again, and back up it goes.
