The Copenhagen Wheel
Heres a pretty cool invention that a group of students from MIT came up with for the James Dyson Award. Read more about it below.
Christine Outram and a team of MIT students invented of a wheel that turns a regular bike into a smart, electric hybrid. The Copenhagen Wheel allows riders to capture the energy dissipated when breaking and cycling and use it when they need it, like when they’re biking up a hill.
The mechanism is controlled through a rider’s smart phone, strapped onto the handlebars. The phone’s GPS system also enables riders to track road conditions, congestion, and pollution levels.
