Another Wind Power Technology Being Installed On Tankers And Container Ships

sure it is just a +100m tower anchored in a few 1000 tons of concrete with +150m diameter rotor ....

I bet that would blow away in a storm.

The site says that the first ship application was in 1926. I see a lot of cargo ships on the bay and none have these things.

How much? You could go into business insuring them against the risk.

A lot of the stuff you sell would have been hard to put together in 1926. It's possible that today's version of the Flettner Rotor would have advantages that the 1926 version didn't.

On a ship? Or in Louisiana?

There are lots of utubes of wind turbines falling over. They usually tip over giant concrete pads when they fall.

Multiply by Kw * Kb * Kn

Kw is fraction of time wind is blowing

Kb is fraction it's not broken

Kn is fraction of time the network wants the power..

Typical products are around 0.25

You snip things you can't dispute. Or maybe can't understand.

Yes, the thing your buddy lost his fortune on. He obviously didn't do the math.

Well, I haven't lost any fortunes yet.

They already have an installed base. If you look in technical brochure, even the smallest model weighs 20 tons welded steel and securely fastened to a 9 ton foundation which itself is welded to hull. They list "survival" wind speed of 70 m/s for all the models, which is say 160 MPH. I take that to be sustained, so it's like 2x anything they will ever see at sea. Every ship is a custom job and may require multiple sails.

They have been installing the things since 2014. Somewhat less than one ship per year, says Wikipedia. It doesn't seem wildly popular.

Surely they will run out of money at that rate.

"The main investors supporting Norsepower are Power Fund III, OGCI Climate Investments, our first venture capital investor Lifeline Ventures Oy, EAKR Aloitusrahasto Oy, Valve Ventures Oy and Korkia Venture Insight. Norsepower is also funded by TEKES – the Finnish Funding Agency for Technology and Innovation, and the European Commission’s Horizon 2020 Framework Programme for Research and Innovation."

Here are some of the investors- these people are no amateurs:

All the more to lose. Investors don't create success; customers do.

They installed a system on a Maersk ship in 2018. Why has Maersk not ordered more?

I guess dirty ships will have to hire clean tugs.

^^^^^^^^ investors

They trialed it for a few years and the fuel savings came in at only 8%. MAERSK has since sold that proto ship:

They won't let them get away with that:
