A very simple car that, runs on water! how simple is that? Using a
simplified rotary steam engine that is upside down I was able to make
a car that runs on water, the water does not need to be replenished as
it is made on the go with a laser.
Tune it by adding more lasers or by changing the wheels size
Version 2.0!
-made it a closed system (no more pipes!)
-double wishbone on the back wheel!
-gear reduction 5:26!
