Wind-Up Cars

By: Davis Deussen

In order to save electricity, we could you use wind-up, or crank cars. Just like most of us played with as kids. So, the more times you crank the "wheel", the more miles you go. That's why we have kids. So, this cuts down emissions because it runs on gears, not gas or electricity, so it uses NO ENERGY whatsoever! The only energy used, is human energy. This is another way to help the environment.
