Yuma Fujimaki is certainly not the first person to make jewelry from scrap electronics components, but IMHO she has done a better job of it than most. [via adafruit]

Shown above is only the most recent work, using this technique, of Photobucket user ionustron, for whom it has been a lifelong hobby. Here’s another:

Is there anything lasers can't do? We only ask because they seem to be improving everything from microphones to railroads, and now researchers from Purdue University have leveraged the power of light to better manufacture solar cells. Using an ultrashort (as in quadrillionths of a second) pulse laser to more precisely scribe the microchannels connecting thin-film solar cells -- as compared to current mechanical stylus methods -- the Boilermakers were able to improve energy transfer efficiency between cells and significantly reduce manufacturing time. Having demonstrated the process works, research continues to better understand and prepare it for use by manufacturers -- sooner rather than later, we hope.

Battery power gets a lot of publicity these days, what with YikeBike and Yogo EVs tooling around. However, that doesn't mean other kinds of ecofriendly propulsion, like fuel cells, won't be part of our transportational future. Suzuki, for one, is betting on hydrogen power -- its Burgman Fuel Cell Scooter just became the first fuel cell vehicle to receive Whole Vehicle Type Approval (WVTA) from the UK's Department of Transport. Having the WVTA stamp of approval means that the scooter meets EU performance standards and can be sold in Europe -- setting it free to frolic hither and yon on the cobblestone streets of the old country. No word on plans to bring it to the US, but a boy can dream, can't he? PR's after the break.
