Zephyr Solar

I am in India at the moment and the southern state of kerela is experiencing extreme floods that have killed 300 people and left nearly 300k people homeless. The infrastructure has also been demolished with no electricity in many areas. Today's hunt is based on that.

Zephyr Solar is a photovoltaic balloon and generator that can be deployed in areas hit by natural disasters. The balloon uses water to inflate and can capture solar energy 50m above ground. A cable at the bottom connects it to energy storage.

Brilliant innovation and extremely useful. Do check it out.
