Simon Sörensen builds remote controlled vehicles and handy gadgets of all kinds, including a hovercraft, an electric hand warmer, and an airboat. His latest invention is appropriate for winter weather. It takes all of the hard labor out of ice skating with two electric motors.
Sörensen wears a battery pack on his back to juice up each motor mounted on the skates, held in place with custom 3D printed parts. Screws in the drive wheels provide traction. You can see his invention in action at the 9:07 mark.
