This guy must be crazy to do those kind of things. I mean I don’t even know how he can ride down at this angle? A lot of snowboarders are good but some are just great.

Li-Ion Battery
now 20X more capacity
using Silicon Wiring

Yes…I mean that if your laptop currently gets 2 hours of unplugged life, these would get 20 hours. Holy Schmoley! The new batteries use silicon nano wires to basically reinvent the way that the batteries electrodes work. Instead of using carbon to store the lithium ions in the anode, they’re using silicon. Silicon can hold far more ions; however, it actually stores so many ions that it literally swells during charging and contracts during use. That swelling and unswelling has generally led to complete destruction of the anode over very little use.
The silicon nanowires allow the anode to absorb the lithium without breaking down. The nanowire "forest" (yes, they actually call it a forest) expands to four times its original size during charging, but the wires don’t ever fracture.
The batteries could be used to store electricity during off-peak hours or to power portable electronics. But the real exciting possibility is that these batteries could power electric vehicles that would store more energy than could be stored in a tank of gas!
Of course, one never knows what will happen when you move a technology from the lab into manufacturing, but this technology is revolutionary and extremely promising.

PLACE BAG OVER THE CREDIT CARD AND SWIPE AGAIN

If you’ve ever stood at a checkout line and frantically swiped your credit (debit) card again and again, only to see error messages, try this little trick:

Slip your bashful card inside a plastic shopping bag (typically hanging right next to the card swipe reader). Smooth out all wrinkles and ensure that the bag is tight and taut on the magnetic stripe side of the card. Now swipe your card/bag combo through the card reader. Success! The plastic bag adds just enough thickness to your card for a persnickety card reader to accept.
