Bike rack collects energy generated by cyclists

Around 68 percent of people in Amsterdam commute to work or school by bicycle, accounting for around 1.25 million miles of cycling a day. All of these cyclists generate an estimated 19.5 million watt-hours of energy each day. This would be enough energy to power thousands of homes – if it could be captured. Now, two Dutch designers think they may have found a way.

Designers Guillaume Roukhomovsky and Blaž Verhnjak have created S-Park, a bike rack system that can use kinetic energy from cycling to charge batteries. The system was proposed as part of Amsterdam’s Clean Energy Challenge. As the rider bikes around the city, their front wheel produces kinetic energy, which is stored in batteries on the bicycle. When done riding, cyclists park the bike in a communal bike rack that’s connected to the electricity grid. The energy that the batteries stored during the ride is then discharged into the electrical grid. The system includes a front wheel that can be popped into any bike frame. The designers estimate that each bike rack could generate about one kilowatt-hour of energy per day.

While Roukhomovsky and Verhnjak don’t yet have a prototype, interested companies have already reached out to help them bring their idea to life. Amsterdam is planning to invest about 100 million USD in biking infrastructure by 2020, and the team hopes S-Park can be part of it. If so, it will join other innovative clean energy projects recently covered by Springwise. These have included energy-generating mushrooms and a restaurant powered with grease.

Takeaway: If S-Park proves effective, it could also be used with rental bikes in other cities, creating a way for bike rental companies to earn income from both the rentals and from generating clean energy. What other ways are there to generate clean energy from everyday actions?
