Froogle
The best way to find products

It's simply the first (and usually the only) place to go to find out where to get hold of anything sold. Rather than winnow through web pages refering to some product, use Froogle to select only sites that are actually selling the thing. Simple, powerful, brilliant. It's Google's better half.

Pee Battery
Gizmodo: Who knew you could use urine to power a battery? The Pee Battery uses the ions in human urine to keep 1.5 volts streaming for 90 minutes, and its makers say it can be tweaked to last even longer. They're even saying that all other bodily fluids work equally well. Sounds like an unpleasant way to get that iPod working again.
These are some batteries that would certainly pass our USB Piss Test. Rig 'em up to power gaming consoles, and we could have ourselves a Pee Wii.

Easy Veins

Shiny Shiny: Young and old, nobody likes needles. But we all have to put up with them from time to time, whether you're doing 'something amazing today' by giving blood, or just having a plain old blood test.
The Luminetx VeinViewer claims to make the process a bit less painful, by showing the needle-wielding nurse exactly where to poke to get that vein straight off. It uses near infrared light to detect veins inside our body. The near infrared light reflects off tissues surrounding veins but not the blood cells inside veins. The system picks up the reflected light, processes it, and then beams a picture back onto our skin, highlighting the vein locations. The result is a strange green web on a piece of plastic on your arm, showing the whereabouts of your veins, so those stab-happy medical people can get it right first time!
