Algodoo

An engine that uses water and gravity as fuel. This model uses (first time for me) a basic script to spawn water. On startup the engine might lag a bit (it can take upto 6000 water particles during startup, when the engine is running it will become less then half of that.

This model has two cilinders and uses the least amount of water (about 2000 particles when running). This engine should be a little friendlier to the slower computers.

Controls:
1 - Enter to start/stop the water spawner (toggle)
2 - Shift to release the brake on the flywheel (toggle)
(3 - Ctrl to give the flywheel a little speed, optional)

Controls are also in the scene
