Man+power

man power is the propulsion that comes from your own body. you can use many different machines,like bikes to use man power to get the machine to work. you can also gety man exiting machines like a waterbird.

But the qestion is, where do we get the energy from to propel a machine like the the waterbird or bike.

We get our energy from food that contains food Energy. But our bodies also need to rest like the el-cars. we canrt youst refuiel our self with energy and have fun 24, 7. but why is it like that. ( i dident get answer from the intrernett or a book or a magasin)

Abs yes, we can propel machines with Man power.
