3. What is Gravity Light?
Gravity Light is a gravity-powered lamp designed by the company
Deciwatt for use in developing or third-world nations, as a
replacement for kerosene lamps.

4. Goal
In the remote areas, it may play a great important role for the
education as well as fulfilling the demand of the power. Moreover,
the power can be stored in the battery so that it may give a great
advantage to emergency situation
> Utilizing gravity on a large scale to generate electricity any time
at any place.
> Minimizing power generation cost.
> Creating cheaper and convenient source of electrical energy.

5. Potential Benefit
> It can perform anywhere.
> Installation is easy.
> No maintaining cost.
> Life span is more.

6. Advantages
> Small area required.
> No maintaining cost.
> Less noise.
> Easy to carry anywhere.
