Forget your cellphone charger at home? IPod battery running low? Soon you won’t have to worry, because your body will recharge your electronics (and no, not in a creepy Matrixway).
Nokia, the world’s largest manufacturer of cellphones, recently filed a U.S. patent for a phone charger that harvests kinetic energy. The technology would allow cellphones to be charged partially through the movement of the owner’s body.
As the number of cellphone users increase, so does the demand for energy, which is jeopardizing efforts to reduce the emission of greenhouse gases and increase energy efficiency.
Each year 1.5 million tons of plastic are used to bottle 89 billion liters of water, and the energy required to manufacture and transport this bottled water severely drains our limited supply of fossil fuels.
But MIT chemist Dan Nocera has discovered a way to make plastic water bottles more environmentally friendly.
Using a special catalyst, Nocera’s new photosynthetic process can power a home using only sunlight and a bottle of water.
