In a clever marketing campaign, Volvo stole wasted energy from cars to charge its new XC90 T8.

In the video above, Volvo creates a clever but simple charging system for its new XC90 Plug-In Hybrid model. The idea was to create a speedbump on a busy road with pipes underneath filled with fluid. As the cars run over the speedbumps and pipes below, thefluid pressure createspower that is able to charge the Volvo charging station next to the road.

It’s a clever marketing idea but they never really show how much energy was created by this setup. It is also worth remembering that the cars that have to drive over the speedbumps waste extra energy by having to accelerate again after the bump. It might be a viable idea if the bump is at a mandatory stop – like a stop street.
