This document summarizes two innovations - an international innovation of a supercapacitor that can fully charge a phone within 20-30 seconds, and an Indian innovation called "walkie mobi charger" that generates electricity through foot movement in shoes to charge phones. It compares the innovations, noting the international innovation is faster but risks getting spoiled more easily while the Indian innovation is slower but encourages physical activity and does not require other devices to charge phones.

DISADVANTAGES :-
● It is not absolutely eco-friendly as it emits harmful
radiations.
It helps in the recharge of car
batteries .

5. INDIAN INNOVATION

6. ADVANTAGES :-
● It is a new source of energy which does not require any particular source of
energy except the body’s movement.
● It encourages physical work.
● This device can charge several models of phones.
● It does not emit harmful radiations.
DISADVANTAGES :-
● It requires humane conditions as man
cannot walk in extreme heat or rain.
● It can often carry dirt and develop swag.
