Bubbles Could Make Cargo Ships More Efficient

Cargo ships could start traveling through clouds of bubbles as a means for increasing their efficiency. Air lubrication consists of www.kachinwomen.com injecting air into the click here dose levitra water underneath a ship to reduce the friction, which should allow the very good site cialis 100mg ship to travel faster while using less fuel.

Naval engineers are looking at the tradeoffs between the energy needed to blow air bubbles underneath ships and http://spionline.com.au/viagra-canadian-pharmacy the benefits in increased efficiency this would provide. At present, they believe this could lead to only here cialis buy now increased fuel efficiency of 5 to 20 percent for freighters.

This technology is likely to make its first appearance on freighters on the Great Lakes, rather than on ocean-going cargo vessels. "Great Lakes ships tend to have large, flat bottoms – an ideal shape for the technology because air stays underneath the ship instead of bubbling to the surface." However, if it brings efficiency improvements, it can be expected that air lubrication will be adapted to new ocean freighters.

The technique's name is Supercavitation, which was explored as a way to make torpedoes "fly" underwater as if in midair. Good to only best offers buy cialis online us know it's being used for commercial purposes.

In some experiments with replica viking ships, it was noticed that their lapstrake construction forced some air into the underwater portions, possibly giving them small speed advantage. Although I have not seen any thorough investigation or such about this, it sort of stands to reason...

Ships don't float on buy ultram online legally bubbles.

They float on water. They sink in bubbles.

not supercavitation

Supercavitation involves creating a cavity (vacuum) around the vehicle with a shockwave, not bubbles of air, its different. Its more playful, possibly even colorful? Anyway its a step in the right direction... airships.

Bubbles bursting?
written by Robert, June 14, 2012
I wonder like how they will prevent the bubble from bursting? I mean bubbles tend to do that, I could imagine one lasting for long, and what if a fish bumps into it? Or am I imagining it wrong and it's actually the kind where its just air being blown out in all directions?
