Boat Blade

The blade in a boat engine is sharp enough to hurt sea creatures and humans, alike. Weeds and plants too can wreck it. The Air Booster is a redesign that removes the propeller blades and uses air pressure to move the boat. A safer out look no doubt, but will it work? That is the question!

      Yes well… This isn’t going to work. I’ve seen them try this on a tv programme before and the boat (or whatever it was) didn’t budge an inch. The problem here is density. Water is much denser than air. Air can therefore not be used to propel a vehicle in this manner. Don’t you think that those hydrojets they use on jetski’s and the like would still be in use if it could be done like this?

      That’s one of those things that work only in theory.
      I predict a lot of bubbles, but there will be NO movement of the craft!
      Although, you can try replacing the flow of air with a flow of water- that might propel it.

    • Remco Boersma says:

      That would work (a little) better… You’re using media of the same density.
