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.
