Was wondering how this originated. Turns out it was developed by Airbus.

It is impressive. There\'s much more to it than meets the eye as they say.

Development was started in 2001 and it was launched 15 years ago. I
wonder how it\'s doing.

Some small fraction of goofy ideas do work out.

Just calculate wind energy for the area swept by a kite

https://engineercalcs.com/how-to-calculate-wind-turbine-power-output/

Betz Limit in wind power extraction

In 1919, Albert Betz, a German physicist, made a discovery on the efficiency of wind turbines. They can’t convert more than 59.3% of the wind’s kinetic energy into mechanical energy.

So, the power efficiency of wind turbines has a limit. It doesn’t matter how perfectly you design a wind turbine either.

In other words, wind turbines can extract only so much energy from the wind. This is because of generator inefficiencies, drive train friction, and blade design.

But even more, this inefficiency comes from wind slowing down. This happens as the turbine extracts energy from the wind. As a result, the wind leaving the turbine flows slower than the wind entering the turbine.

This creates a blockage like in traffic on the highway. As cars slow down in front of you, you’ll eventually need to slow down too. No matter how far back you are from the traffic jam.

Another way to think of it is to imagine what would happen if the turbine captured 100% of the wind power. The wind would simply stop.

And for a turbine to properly work, some wind needs to flow out from the back. Otherwise, the blades won’t spin.

In short, there’s a limit on the amount of air that can pass through a wind turbine for max power output. This limit we call the Betz Limit.
Power Coefficient, Cp

With that out of the way, let’s take a look at the Power Coefficient, Cp.

This is the ratio of extracted power by the wind turbine to the total available power in the wind source.

C_{p} = \\frac{P_{T}}{P_{W}}, where C_{P\\:MAX} = 0.59.

Where the Betz Limit is the maximum possible value of C_{p}. Thus, 16/27 or 0.59.

We can now update our power equation to read: P = \\frac{1}{2} \\times \\rho \\times A \\times v^{3} \\times C_{p}

Kiteboarding - Wikipedia
https://en.wikipedia.org/wiki/Kiteboarding

Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, or snow surface. It combines aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less

History

Late 20th century
In October 1977 Gijsbertus Adrianus Panhuise (Netherlands) received the first patent for KiteSurfing. The patent covers, specifically, a water sport using a floating board of a surf board type


Environments

Kitesurfing on water includes freestyle and big air using a kiteboard similar to a wakeboard, kiting in waves using small surfboards with or without footstraps or bindings, foiling, and


Governance

International kiteboarding has several promoting organizations and has undergone many changes in the governance of the sport, including long-lasting disputes between several of those entities, trying to negate each other the right to promote such


Techniques

Kiteboarding can pose hazards to surfers, beachgoers, bystanders and others on the water. Many problems and dangers that may be encountered while learning kiting can be avoided or minimized by taking professional instruction through lesson centers. Kitesurfing


Kitesurfing Records

Jump records (height, length, time)
Nick Jacobsen achieved the world record for the highest kite jump measured by

It gets the wind-catching gizmo up to an altitude where winds are more
reliable than near ground level. If you could tap the more-or-less permanent cyclone

Because it\'s a circular wind, any energy you miss on pass 1, is still there on the next
cycle...

Windmills are stationary, so any wind is relative wind.

Claim is 20% reduction of CO2 emissions- and of course that depends- on a lot of things. Japanese are installing them on their K Line.

They\'ll need this and more. The U.S. has the Clean Shipping Act of 2022 in the works. Some interesting statistics about it here.

The video looks fake to me. And why is the sail doing aerobatics?

The full answer is : It\'s complicated.

Might have something to do with this:

I\'m not going to spend any time on it. It\'s simpler to defer to the expertise of the people making the system work.

Popular lifestyle:

1: Invent something really loopy

2: Fake a bunch if pics and vids and a glitzy web site

3: Raise a lot of money

4: Enjoy life for a couple of years

5: goto 1

Totally. Sailing ships? Who ever thought of anything as stupid as that? ;)

Some ideas just keep coming back, like adding sails to diesel ships,
airships, home windmills, flying cars, jet packs.
just calculate wind energy caught by a kite
to learn what is and what is not feasible
There\'s an impedance-match problem too, mismatch of ship velocity vs
wind velocity. Windmills have variable-pitch blades.
it is also (mostly?) a safety feature so they can feather the blades in high winds
we can start from kiteboarding, kitesurfing
\\to make basic calculations
than build kite powered small ship

Kiteboarding - Wikipedia
https://en.wikipedia.org/wiki/Kiteboarding

Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, or snow surface.. It combines aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less

exactly,
so kites for diesel ships are designed as rigid structures,
and nothing falls into the water if no wind at all

Nevertheless, kite for diesel ship is an old fake

I recall experiments with vertical fixed sails, installed on top of diesel ships.

But not aware of any success story
