The Challenge: Recharge a Battery

Page: 1 2 3 4 5 6 7 8 9 10

Because we have a battery to store electrical energy, we only need to use the generator when it's convenient to do so. As we couldn't always depend on the wind or waves we took the easy option on the island and used muscle power. To make the best of our muscle power and increase the speed at which the axle turned, we used a big wheel as a gear.

This allowed us to successfully to recharge a dead battery ready to power our Rough Science equipment.
