This is what happens when you get a couple of cheap RC cars and add proximity sensors, extra batteries, robot brains, and name them Steve McQueen and Burt Reynolds: totally-automated racing all around your house. These electric robocars can detect the walls around them and race against each other for as long as the batteries last. The resulting Tron-lightcycle-like action is impressive.
Want! Can’t wait for the instructions
Sumitomo’s motor uses high-temperature superconducting wires instead of the copper wire typically used in the coils in electric vehicle motors. When cooled to an extremely low temperature, electrical resistance and current loss are reduced to nearly zero, so the motor can operate with greater energy efficiency and torque — in other words, the motor uses less electricity to do the same amount of work. The company says the prototype vehicle can travel 10% farther than conventional electric vehicles running on the same type of battery.
Because the hassle of liquid-nitrogen cooling is definitely worth a 10% improvement in performance. Don’t want.
