DeWalt
Wired Magazine on Cordless Tools
This month's edition of Wired magazine has an article on DeWalt's new M1 cordless battery technology.
The M1, based on the same lithium-ion technology used in your cell phone and laptop, is the first product from MIT spinoff A123 Systems. Cofounder Yet-Ming Chiang, a materials science professor, succeeded in shrinking to nanoscale the particles that coat the battery's electrodes and store and discharge energy. The results are electrifying: Power density doubles, peak energy jumps fivefold (the cells pack more punch than a standard 110-volt wall outlet), and recharging time plummets. Going nano also solves a safety problem. Regular high-capacity Li-ion batteries tend to explode under severe stress, like if they're dropped from a ladder.
They end by saying that the technology in the M1 is ultimately destined for automobiles. Now that would be a cool interchangable power source!
Hello Kitty Belt Sander
If you've been looking for a belt sander to round out your collection of Hello Kitty tools, wait no longer.
Actually, this is a one-of-a-kind belt sander racer someone made for competition racing. You can see the full recap of the modifications they made here.
