Who says you need old fashioned gasoline to get going at high speeds? Last weekend, a car powered solely by 192 AA batteries got going up to a speed of 75mph. That might not seem like a lot to you if you're used to driving around in a normal car, but this thing is run by the same batteries that ran your first-gen Game Boy. That's pretty impressive.
It was all done as part of the Oxyride Speed Challenge, a competition to see how fast a battery-powered car could travel. Believe it or not, 75mph was a new world record. The vehicle that broke the record weighed a mere 84 pounds, which explains why it was so efficient. Don't expect AA batteries to power commercial vehicles anytime soon, but exercises like this help researchers develop new technologies that actually will.
