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.

There is enough evidence to suggest that we can already have fully electric cars that are far more efficient than internal combustion motors. We can thank Bush and the rest of the Oil Cartels for letting our pollution problems reach epidemic levels today. I would suggest seeing the documentary "Who Killed the Electric Car?" to find out more about this long history of suppressed technology.

Hopefully a discovery of this proprotion, a more efficient battery, will actually be integrated into the marketplace and not repressed like the thousands of other amazing discoveries made in the past hundred years.

Cross your fingers....

Lol conspiracy theories.

The reason electric cars haven't caught on is because the suck so people don't want them. Its a market problem.

For one, I personally don't like being passed by everyone else, esp since im used to being able to hit 100 on the on ramp with ease with my 4.6L 800+ HP V8

Two, I don't feel like driving out of my way to the one of two electric car charging stations and sitting there for an hour.

[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:

http://marketplace.publicradio.org/i/news/b_tesla_...

http://en.wikipedia.org/wiki/Tesla_Roadster


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...

Also is the fact that electric cars look so stupid. You can always tell them by their cheap plastic curvy 'furturistic' styling. If auto makers just offered electric versions of their current hot selling body styles, there might be more interest.

An electric car equipped with these "batteries" could actually be recharged while still on the road and moving. If the standard set of batteries could go 20 or 50 or 100 miles/kilometers between charges, then the highways could have high power induction grids every 5 or 10 miles/kilometers. If you drive over the grid, you get charged to perhaps 90% capacity and then billed for the amount of power you used. Then just merge back into traffic. High power substations could keep the voltages high for quick charging. Existing gasoline stations just add induction grids to serve multiple fuel types.

Hmm something about being zapped with a 100kW arc... you think slot car contacts wear out fast? lol

Ah induction... well... hmm... having to limit power to safe levels would imply longer charge times.

induction grid in a freeway? not very feasible...too likely to ground itself after a period of years. and very expensive to build "new" into a road.

I love how those articles of the pure electric car always talk about the ease of plugging the car in in your garage overnight and letting it recharge overnight when electricity is cheaper.
OK, now picture 200 million of those vehicles charging themselves overnight. no more cheap rates.
Not to mention that I have yet to live (or ever heard of) residential power that is billed based on time of day. 99.9999% just look at your total KW-hrs. There's proposals for that kind of billing in California and maybe other places, but it would require a huge investment by the power companies for that new meter set up on your power connection. The cost of which, of course, will be passed on to the consumer.
And of course, none of that will help us folks who live in apartments and can't install that kind of equipment in our parking area.

I don't think its a bad idea, electric cars will probably be inevitable at some point (I'm thinking after we perfect Fusion power plants...! or gas reaches $40 a gallon a la SJgames "Car Wars") But its not going to be as simple as current proponents think. There's a lot of infrastructure to consider.
