The new batteries can also be recharged hundreds of thousands of times say MIT researchers

You could be charging your long lasting batteries in a matter of seconds in the future if several researchers at MIT get their way. According to a report on ScienCentralNews, researchers at MIT have discovered a new way of making batteries that involves using millions of nanotubes. Leaping over traditional battery technologies, the new types of batteries are based on capacitors, which have been around even longer than the battery itself.

A capacitor maintains a charge by relying on two metallic electrodes. The actual storage capacity of a capacitor is directly proportional to the surface area of those electrodes, and unfortunately making a capacitor in traditional battery sizes means that the electrode surface area is simply too small. To overcome this, the researchers cover the electrodes with millions of nanotube filaments, effectively increasing the surface area.

According to research team leader Joel Schindall "[the nanotube battery] could be recharged many, many times perhaps hundreds of thousands of times, and ... it could be recharged very quickly, just in a matter of seconds rather than a matter of hours." With such promise, Schindall and his team believes that the new technology will revolutionize portable electronics as well as the automotive industry. "Larger devices such as automobiles where you could regeneratively re-use the energy of motion and therefore improve the energy efficiency and fuel economy."

The research team at MIT is hoping that this new promising technology will show up in the market in less than five years from now.

well, it happens so that i've moved to States so we get wet together. i was just trying to say that 110 seems wastefull (transmission loss, more expensive wires), but i,m in no way an expert on 3p current (and the effective voltages on both sides of the pond). as the simlest example of waste - try to use a vacum cleaner (~1k) and check the power cable - hot - i've never noticed the same thing back in 220 land (unless the power cord was the sh... possible). 60 Hz - good for old tv (less flicker but lower resolution over the same band). different standards - bad for all of us (unless all the stuff you use works over any voltage/frequency)
