I was just browsing through make, and tumbled upon this really cool idea - motorway wind turbines. It can reduce the carbon footprint of the automobile. And some electricity. And less auxiliary weather meddling. The wind created by by the stream of cars on the motorway and it's effects on the local weather and the one in China are still not studied, regardless of the advances of chaos theory and other intellectual beauties.

Driving at 90mph - get bladed? Can be really good for "drive safe" campaigners.

update:hmm, there a discussion on slashdot about the same core idea, thanks dogsbody, my festive friend.

TAI-CHI is an interesting project some colleagues of mine work on together with a few interesting partners. The guys are turning various surfaces into touch, probably better described as tap sensitive, interfaces.

In it's basic form it is a few pieso-sensors, some low cost chips and lightweight software to grab the coordinates on a pre-calibrated surface. The calibration process is not too different from what you would do to calibrate a PDA's screen. Essentially it is not really high-tech, as in multi-million, cluster driven, intelligent multi-mobile-agent networks over-engineered gizmo.

The tech was tested not only on flat surfaces, but on staircase railings and other not so usual places.

We were dreaming about, gesture recognition and other cool derivatives of the technology. But that's hopefully the future

And it appeared on boing-boing
