It looks neat and might help in emergencies or special conditions, but if one takes a look at the wattage, sadly… 50 kW is very limited power. Probably not good for widespread use.
The helium-filled S500 blimp ascended to 500 meters above ground in the city of Jingmen, generating power at a rate of over 50 kW, according to Beijing SAWES Energy Technology Co Ltd, one of the developers of the system.
Emergencies is exactly what they recommend it for.
“S500 is developed for scenarios such as emergency rescue, surveying and mapping, and urban security. When an earthquake or flood occurs, it can be quickly launched to ensure on-site power supply and communication,” said the company’s chief technology officer Weng Hanke.
Plus, it’s first steps. Who knows what can be achieved down the road.
I’ve had the same notion floating around my mind for a while now. Always interesting to see ideas made manifest (even if I’m not part of the development).
