Propeller Collar to recharge batteries

Emily

Age 10Sunderland, UKAug 2024

Back to all ideas

You put the uncharged batteries into the battery pack on the back of the collar. You put the collar on the dog and then as the dog runs the propellers turn round generating energy that recharges the batteries so that they can be reused.

Little Inventors team says

What a way to generate sustainable power! You are keeping your dog happy as it gets plenty of activity in Emily and keeping the planet happy with a greener form of energy. A collar wouldn't get in the way of the dog either, so it's convenient too. Keep inventing!
