Scientific breakthroughs and inventions are really required at present times when global warming is emerging as one of the major problems. However, even your smallest effort to contribute in this quest counts. Designer Elizabeth Joy Wong has worked on a simple phenomenon and has prepared a bicycle powered generator prototype. A friction drum attached with the bicycle wheel spins the alternator when the user pedals the bicycle and generates electricity which is stored in the power pack.
The idea is to provide green energy in emergency situations or otherwise when you don’t want to use gas or grid electricity. It is a small invention, but appreciable.
