He is leading a research team at WPI that is working to improve the output of the hydrogen fuel cell. Renewable energy sources are the Holy Grail. The number of cars on the road is expected to double in the next 20 years. We only have 50 years of oil reserve left. Remote controls and personal stereos devour those cylindrical cans we call batteries.
Batteries store an electrical charge and furnish a current.
Electrons are the raw stuff of electricity. Batteries must be able to spawn electrons in order to power remote controls and radios. When you turn on a battery-powered gadget, a chemical reaction in the anode produces zinc ions and releases electrons. After their grueling task, the electrons return to the battery via the cathode where they react with the manganese dioxide. After a number of chemical reactions in the electrolyte, the reacted electrons, now in the form of water, travel back to the anode to react with the zinc ions.
