Design and make a toy that converts energy
Im thinking off creating a toy that uses natural energy and coverts it into electricity. For example a water mill and wind turbins are things that converts natural energy into electricity. Even using a solar panel can work to create energy. My idea is using solar panel to store the energy that it takes from the sun then it can be used when its opened as a light or something.
And the other idea I have is that I want a flashlight that can generate energy by spinning a wrench.
The pro about this is that this can create energy using things like water falls, and with the gravity of water it seems like its something that can work
cons is that the materials used in this seems really complicated to get.
Pro is that its something that looks really simple to make, with all the materials and everything it looks cheap and effiecent
con it does not look like something that can actually function
Pros its something that can easily and it looks usable
con the magnet is quite large so it might be hard to find
