From childhood we have seen balloons filled with a gas lighter than air fly up into the sky. During independence day many of such balloons are released for peace.

Have we ever thought we can use the energy of these moving balloons?

The idea is to utilize the energy of balloon moving in the air to lift a weight. With the further development in this technique , this can be utilized to drive a generator to produce electricity.

In the illustration attached i have shown lifted balls in a cylinder with the help of air pumped from the air pumps. These air pumps are driven by balloon(s) attached to a plate.
