Over the years I’ve seen many such plans to float stuff in balloons, one idea that seemed very interesting at the time was the idea floating a giant balloon to not only handle radio etc, but to reflect light or otherwise provide light to a disaster area. A quick search of the US Patent Database provides tons of examples of mostly half baked vague ideas (a speciality of the US Patent Office) of using balloons for all sorts of goofy things. I think what matters is the last truly original idea occurred about 3,000 years ago and really the only thing that matters now is successful implementation of ideas so I wish these guys the best of luck, but please don’t bring one down in my backyard.
Please bring one down in my backyard. Just don’t ask for it back
