Materials like graphene (above) and carbon nanotubes are likely to be the next big thing in energy productionFaced with dwindling resources, a polluted environment and a changing climate due to the use of hydrocarbon fuels, as well as resistance to ideas of expanding nuclear and wind power, scientists have been exploring some very interesting ways of generating and storing electricity.
One promising field has been energy harvesting, which works simply by having the right materials and technologies in place as we go about our daily lives. This can involve clothing, sidewalks and roads made of new piezoelectric materials, that produce electricity as we move, walk along, or drive our vehicles, or it can put technologies to use that are already ubiquitous in our modern households.
South Korean scientists have come up with a way of using dielectric materials to convert the movement of water into electricity. This can be incorporated into roofs to harness electricity from rain, or it could be used in toilets to produce electricity anytime anyone flushes. Here are some demonstrations of theRead More »from Researchers produce amazing new alternative energy sources
