Funny, was just on one of the German info channels yesterday on Astra 1 satellite
Also these rotating round colums (forgot the name) to aid ship propulsion.
ZDF-info? Or cable 1 info? or that other one (there are 3 I know about and
frequently watch).

Thanks, yes those.
There seem to be ferries too that use those. to save fuel.

Might be a few supply chain issues but they're really low in pollution
as long as you don't piss over the side.

The short blurp mentions something about perpetually doing figure 8 maneuvers to increase the overall performance.

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.

It is doing the aerobatics to go and stay aloft.
You should have seen that TV program... Was demonstrated there by hand flying
a kite like that.

Makes sense. The air doesn't change speed instantaneously, so always
moving into fresh wind would get you more momentum overall.

One bunch of lunatics tried generating power with actual kites spooled
out by winches that turned generators.

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}

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
