This week on TreeHugger, an app that rats out bad drivers to the DMV, an elliptical commuter bike, $980 solar powered pants (yes, pants), hands-on with high-tech LED bulbs, hand-powered table saws, and more!

$1,260 Jacket, $980 Pants Prove Solar Fashion Has A Long Way To Go

Despite the fact that solar cell technology is constantly improving, there seems to be little indication that fashion incorporating those solar cells is improving at all. Example: Silvr Lining's GO Solar Power Collection. Their new line of jackets, vests and cargo pants sport solar panels for charging gadgets while on the go.

Fun with new LED bulbs — Qnuru 6.4W and 9.2W LED Lightbulbs (Product Review)

To paraphrase William Gibson, the future of lighting is here, it's just not evenly distributed. Light-emitting diodes (LED) lightbulbs have been coming on the market in the past few years, but their quality varies greatly, from "almost perfect" to "horrible" (kind of like the early compact fluorescents). I had the opportunity to spend a few days with two LED lightbulbs from Qnuru, and I'd like to share my impressions with you.
