I decided to cast a toy truck wheel in aluminium to explore and develop the idea of adding weight to a toy + flywheel motor.
The theory behind this idea is that by adding the extra weight it would make the toy go faster/ further, thus generating more energy.
As a further development i thought this could be an ‘add-on’, so when the child have accumulated enough energy (economy) they can then upgrade their wheel to a heavier, faster and better generating one.

*it is much heavier and makes an amazing sound when rolled around the studio*
