Panasonic's Oxyride Car
Panasonic had a large presentation and display to talk about its soon-to-be-available Oxyride batteries. The claim: Your digital camera will run twice as long on these batteries as it will on normal alkalines. To drive the point home, they had the Oxyride car on display:
A (smallish) person gets in this car, and then the Panasonic folks power it up with Oxyride batteries.
The impressive part is that they power it up with just two batteries:
Is the car going to go 100 mph with just two batteries? No. If you look elsewhere on the Web, you find that the car only travels about 1 meter/sec and has a maximum range of a mile or so. Still, it was very funny to see that two little batteries can get the thing moving at all.
