We would like to develop a car that runs on salad.
Yes, it would work; there is a Swedish company that developed an engine that runs on pellets, burning and loading an electrical engine. Right now they use it only for boat engines.
So, instead of wasting our left overs we would make pellets from our Bak Choi, salad and other things we grow in our greenhouse and run our delivery cars on it.
To build a prototype we need EUR 200 000.
