some awesome shit., thanks for posting.

this is new knwlege again :)....

damn. that thing was barely spinning and was almost horizontal when it hit the water.

btw.... that dam seemed to be very thin for the volume of water it was retaining.

Right off my head I can think of plenty of ways they can use this. Pretty cool.

That ship was really cool.
