Recharge battery in 3 seconds...

MIT says they have developed a way to recharge a battery in 3 seconds. Imagine recharging your cell phone this quickly. "Oops, batteries low. Let me recharge... Ok DONE."

Also, imagine going down the road in an electric car. When the battery level gets to 20% or so, the car can automatically recharge the battery using some kind of alternator (based on the forward motion of the car.)

This is big news and it's REALITY. The article says we could see this technology in as little as 2 years.

The article raises some interesting questions regarding current demand and cabling to charge full size batteries.

If the battery can charge in three seconds, what is keeping the battery from discharging in three seconds?

They don't call it the MAGIC Institute of Technology for nothing! :P

But seriously, that's a good point. I won't pretend to even understand how they did this, but if the article didn't mention anything about increased drain times, maybe they found a way around it? In other words, the answer to your question may be far more complicated than you think...

well just think of it like it is now...i charge my battery fully in ruffly 2 to 2.5 hours....but it lasts me about 17 hours....not just 2.5.....its the same concept why would it discharge in 3 seconds...its not using that much energy its just taking in that much enery

This is VERY exciting for electric cars. One of the biggest problems is charge time. If battery technology could provide 150 miles distance and a recharge could be done in under 5 minutes..... wow. Goodbye gas.

I'm not trying to put a negative spin on this thread but do you really really really honestly think the government wants to stop using gas right now? Think of have many hundreds of billions of dollars of tax revenue they would lose.

Don't worry new taxes on electricity are already planned. They'll get their money out of us one way or another!

good point. In situations like these we normally don't see the big picture. There is a LOT of money tied up in gasoline, but imagine how much money is tied up in getting it here from other countries.

Think of it this way: America has a limited supply of gas, and we use a lot more than any other country. If we had a technology (home brewed btw) that could suddenly put our gas usage so low that we could supply ourselves, the money saved that we are spending BUYING GAS from other countries would definitely outweigh the money made from taxing that gas.

This technology could put America in a position where we literally could start selling gas to other countries more than we buy it. Any situation where you sell more than you buy is a good situation.

I don't see us going completely electric (maybe some cars will be, but there's simply not enough power there.) I see gas-electric hybrids being THE norm once this technology hits, but who knows. The article could have over-hyped it.

Read the comments... The 2nd one down brings up a valid point.

you can discharge a battery in 3 seconds but you control the discharge rate.
