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.

It's stepped down to 120v for residences and commercial buildings but I always remember seeing "[warning 50k volts] ont he power poles next to the giant transformers.

Oh, and to whomever mentioned super conductor lines or huge, thick, heavy copper lines...silver is the best conductor, better than copper or gold (gold being second best), for both heat AND electricity...hence, silver would be a better option.

I thought platinum was actually better?

Ok, I found out that silver does indeed have a higher conductivity than platinum, however platinum wiring doesn't oxidize.

One of silvers greatest strengths is that silver oxide is more conductive than silver. So the old and rusted, does not reduce performance.
