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.

[sarcasm] Yes, you are sooo right [/sarcasm]

[even more sarcasm] Ugly, slow electric cars, like for example the new one to be built by Lotus:

0-60 mph (100km/h) in 4 seconds

You'd better get used to being passed on the on ramp by electric cars.

Meanwhile, you better get used to paying twice as much for "gas" as you do now. (and when I say "gas" I mean petrol, not the hot, polluted gas/air coming from your mouth or your exhaust). In europe, we already pay more than twice as much as you for petrol.


Oh, and by the way, there is a reason that electric cars have been poor until now - it is because of the corrupt relationship between USA's oil and car industries.

See: http://en.wikipedia.org/wiki/Who_Killed_the_Electr...
or http://www.ev1.org

...for details of how GM deliberately and literally crushed a very successful electric car programme.


I, for one, am looking forward to a future where cars (or whatever transport we use) are powered by renewable or non-polluting sources like wind.

And I can buy one of those where? And charge it where? And what about people who just want the Accord they are in love with but in an electric version, instead of a roadster?

All I'm saying is that there are plenty of market barriers to electric cars, namely recharging as conveniently as pumping gas, and variety of models so that we aren't all driving the same two electric cars that give the choice of either a F1 roadster or a bar of soap. It's a chicken and egg thing.

And 0-60 mph in < 4 seconds is nothing new to me.

I sat down somewhat recently (within the last month) and figured this out, but I don't have the numbers handy here. If you remove any and all taxes from the cost per gallon/liter then the US pays more than Europe. Which means that you pay more because your overload government taxes you so...
