Yeah, it is like something you see in Popular Science magazine, we will see if they can do anything with it.

Neat concept though.

Sounds like my phone message,make it stop.

I thought video meant the picture would move

Good luck to them. It's not about carbon emissions but fuel savings (and reduced shipping costs).

If you've ever been on a tall vessel in a stiff breeze, you understand the idea pf sail area.

But there was also a robovoice statement about ships using windmills, not sails, for propulsion.

That requires treadmill testing with a fan.

Would be better off if propelled by magnets

Needs moar treadmill to test its theories.

Microsoft Suzy?

Lost me at about 5 seconds in with the CO2 BS.

If you listen further they talk about 60% fuel savings.

That would be a big if achievable.

So your sail is always deployed. How do you stop?

Pie in the sky bullshit. Nuclear needs to become cheaper.

Welcome to 1980

http://en.wikipedia.org/wiki/Turbosail





The Alcyone
In 1980, Jacques Cousteau dreamed of creating a ship with a modern engine that would be powered, at least in part, by the wind, a clean, free, renewable energy source.

Aerodynamics
Cousteau and his associates, Professor Lucien Malavard and Dr. Bertrand Charrier, used a fixed cylinder that looked like a smokestack and functioned like an airplane wing.

It consists of an airfoil, vertical and grossly ovoidal tube, with a mobile flap which improves the separation between the intrados and extrados. An aspiration system pulls air into the tubes, and is used to increase the depression on one side of the sail; a reaction force occurs as the result of the pressure difference. In this way, the "sails" act as wings, creating both lift and drag.

A movable, flap-like trailing-edge shutter and a fan-drawn aspiration system are used for control and increase the magnitude of the maximum reaction force.

As a result of this design, the turbosail provides a reaction force, a component of which, thrust, is available for the direction of travel. Just like an unpowered sail, thrust cannot be obtained when making headway directly into a headwind, nor can it be obtained without wind. However, the use of fan-drawn aspiration, which requires engine power, increases the generated reaction force compared to the unpowered device.

Propeller-based propulsion can be used in conjunction with the turbosails. These traditional engines, together with the angles, and suction power of the sails, can be coordinated with computers to control the ship.

Duh, a human narrator would have been expelling earth killing CO2 and H2O vapor, you Gia hating shitlord.

No caterpillar power?
Any magnets involved?
Is there a treadmill underneath?
We have questions.
Where the fuck did they come up with the narrator?

Does this mean that those Chinese faux gun parts will take three months to get here rather than the usual three weeks?

Just curious.

Or even trim the sail to match the intended course.

As both a steel and diesel sailor and a cloth and stick sailor, all I can say is...






Good fucking luck
