Designer Tay Kian Khuan brings you the 720 Skates which are designed for pro competitions. The main difference between 720 Skates and inline skates is that the wheels are set on independently rotating gears instead of an inline track. With this addition the skater gains the ability to spin 360º in place and skate sideways. If this concept goes public it will have two certain effects: a new variety of sweet tricks to do, and the same old injuries for those who can't skate.
The gadget in the video is a sensor controlled electric skateboard. When the rider leans forward, the board accelerates and when the rider leans back the board decelerates to a stop. The board is completely hands free. In the video, the board is hooked up to a power supply, but a battery pack can be used. The Seg-Board was designed and manufactured by four Carnegie Mellon University mechanical engineering students.
