Electricity is very essential and the resources to produce electricity are limited. Also, most of the energy resources we use to create energy are non-renewable and harmful for the environment.

In such scenario, creating energy through gravity is extremely useful and innovative. A weighted bag is hung and winched (a pulling device, which pulls)  up. With this the weighed bag descends down gradually.

It uses this weight to drive a gear-train and generate electricity from the kinetic energy created, sufficient to light up an LED bulb.


This really helps people in rural areas with lack of electricity to light up their houses using nothing but “Gravity”. This is more efficient than solar energy.
