Designers Set Sail, Turning to Wind to Help Power Cargo Ships

Saw this article last week in the NY Times.

Quote:
If the world’s shipping fleet were a country, it would be the world’s sixth leading emitter of greenhouse gases. To reduce those emissions — and, not incidentally, to conserve expensive fossil fuels — cargo ship designers are now turning to the oldest source of power there is: the wind.

The new vessels, mainly still on drawing boards and in prototype, look nothing like the graceful schooners and galleons of centuries past. Last spring, for example, the University of Tokyo unveiled a model of its UT Wind Challenger at the Sea Japan trade show. It has nine masts, each 164 feet tall, with five rigid sails made of aluminum and fiber-reinforced plastic; the sails are hollow, designed to telescope into one another in rough weather or at anchor.

Then there is the 328-foot, 3,000-ton cargo carrier being designed by B9 Shipping (pronounced benign), part of the B9 Energy Group in Northern Ireland. Its three masts rise 180 feet, as tall as a 14-story building.

Powered by a combination of wind and a Rolls-Royce biogas engine, it is intended to operate with no fossil fuels.

A model of the B9 ship was tested last month at the University of Southampton in England. “The tests were promising,” said Diane Gilpin, a founder-director of B9 Shipping. “They validated the economic case for deploying a B9 ship on certain trading routes.”

The next step, she said, is to seek financing for a full-size ship to demonstrate the technology. It would cost $45 million and take three years to build.

Several factors are driving efforts like these. Effective this month, ships in North American waters are required to burn low-sulfur oil, which costs 60 percent more than bunker fuel. The United Nations’ International Maritime Organization is also phasing in restrictions on greenhouse-gas emissions by commercial ships.

Meanwhile, the price of bunker fuel, which accounts for most of a vessel’s operating cost, has been rising steeply — 600 percent over the last 10 years.

I remember seeing those concept sail powered ships in Popular Science back in the 70's.

Yup, I remember that too. Welcome back to the future.

In 2005 Toyota asked a German company to design a "green" ship to transport the
Toyota Prius across the oceans. The result was the ORCELLE.

Wind, wave, solar, and hydrogen fuel cell.
Some of the hydrogen was to be produced on board using the energy from the wind wayve and solar production.

At this point I think the farthest this concept has been realized is the solar hybrids.

Strange that no mention was raised on rotor ships which, though aren't 100% emission free, do offer another alternative to reduce dependence on bunker fuel.

Speaking of Popular Science, you'll find a number of articles going back to 1925 on the subject.

Interesting thread, this---.

I remember reading about the rotor ships a long time ago, but never understood how they worked.

Still don't---.

Unlike a rotor ship, which uses wind power to turn an underwater propellor, the Baden-Baden uses cylindrical rotating 'sails' to generate lift like a traditional sailboat. Has a keel like a sailboat. I always wanted to build a model of her.
And I remember when the Skysail guys were pushing for cargo ships to be retro-fitted with giant kites to offset the trans ocean fuel consumption. Seams logical. A simple addition to an existing ship, and something that can be deployed and retracted easily, so you don't have to worry about protecting these giant masts while in port. Cuts out somethiing like 25 percent of the fuel used.

Ahhh the god ole' Prius. The car that is apparently "green" but makes tons more toxic industrial waste to manufacture than any other. It's so nasty it actually offsets ANY gas savings from what I have heard.

Top Gear UK gathered all this info cause they hate it, lol

I loved the BMW M3 versus Prius; The Prius driven flat out, with the 400hp bimmer trailing leisurely just to keep up.

Bimmer got better MPG, Ha.

I had the displeasure of renting a Yaris, which I think its the Priuses' combustion only relative. What a horrid vehicle. Gave me the creeps driving it.

Has nobody suggested the MOST obvious solution: stop making everything across the sea in China?

I was at the hobby shop earlier this summer, and someone
came by the counter looking for "radius'd track" for his railroad layout.
Leonard told him that it was out of stock, and would not be in till late fall, or winter.
The explanation was that WALTHER was pulling all of its molds from China, and
bringing production back to the United States...

There are more than a few companies re-evaluating the cost of labor vs the cost of shipping.

You would be surprised at the amount of production that has been moving back to American shores (that includes NAFTA countries & South America) since costs started rising steeply in China over the past several years but keep in mind its much, much more than simply labor vs. shipping costs that dictates what is made in the USA.

As Steve Jobs so aptly reminded us in early 2011 when he replied to the President's question about bringing manufacturing back to America, some categories won't ever be coming back & that certainly doesn't apply exclusively to Apple.

http://www.nytimes.com/2012/01/22/bu...le-class.html?

Of course, trade is a two-way street so don't forget China, among a few other developing countries, love buying American products so am sure we'll still be seeing the need for alternatively powered cargo ships.

A Prius

If you look at the gas mileage of a Prius, they get better gas mileage in the city, than they do on the hwy. Reason for this is..... the batteries are used mostly in the city with the gas motor just used to supply top up of the batteries. On the hwy, the engine is running and reving at it's max all the time to produce electicity for the motor.

engine runs on gas
motor uses electricity

Why do you think this is happening now - soon it will be to expensive to move all those Wally world consumer goods to this country by sea due to oil prices. Ergo the renewed interest in eco-power, except that in this context, there is no one to charge you for using the wind to keep from having to outsource all those Chinese and Vietnamese jobs back to the debt-peasants of the US.

Yeah, there will be companies just lined up waiting to get in on that deal.


The answer is to ignore this greenhouse emission nonsense and refuse to align with their silly treaties. Let those preaching this swill foot the bills, and see how long the chorus lingers.

Does anyone remember the N/S Savannah? She was also going to show the way to reducing fuel costs. Lack of cargo capacity and crew costs (unions) killed that quickly. These wind ships will go the same way. Just wait till one of those huge masts accidentally snags an albatross. There will be a world wide clamor to scrap every one.
