NEW SOURCE OF POWER?

A new way of generating electricity from flowing water could mean that in the future you will never have to charge up your mobile phone again. Instead of a normal battery, mobile phones could be fitted with a battery that uses water – you just need to pressurise it regularly.
Research published today by the Institute of Physics journal, Journal of Micromechanics and Microengineering reveals a new method of generating electric power by harnessing the natural electrokinetic properties of a liquid such as ordinary tap water when it is pumped through tiny microchannels. The research team from the University of Alberta, Edmonton, Canada, have created a new source of clean non-polluting electric power with a variety of possible uses, ranging from powering small electronic devices to contributing to a national power grid.
The research was led by Professor Daniel Kwok and Professor Larry Kostiuk from the University of Alberta. Professor Kostiuk said: “This discovery has a huge number of possible applications. It’s possible that it could be a new alternative energy source to rival wind and solar power, but this would need huge bodies of water to work on a commercial scale. Hydrocarbon fuels are still the best source of energy but they’re fast running out and so new options like this one could be vital in the future”.
Interesting. But can it replace Middle Eastern oil?
