If there’s one problem with solar power, it’s that it can take an enormous amount of real estate to generate a sufficient amount of power.
Well, maybe not for much longer. I just tripped across this entry from last year’s Re:volt awards. The idea is to use helium-filled balloons that are embedded with solar arrays. Power is brought down the cable where it would be devoured by a hungry nation.
The design would save the costs of buying the real estate and allow you to put much more power generation in the same acreage.
Not sure if it’ll fly, but it’s a great concept!
