Will The Maiden Voyage of A New Ship Equipped With Giant Kite Spark A New Future of Ocean-Going Vessels? Why?

Question

On a blustery day, the kite can provide up to 35 per cent of the vessel's power, according to its creators.

If the maiden voyage is a success, the team that came up with design hope to double the size of its kites to 320 square metres, and expand them again to 600 square metres in 2009. By 2015 they hope to fit out 1,500 ships.

What is more important?

They say it will save the Beluga's operators 900lb of fuel per DAY. Did you ever imagine a return to "sail" ships in this century?

Is it equally important that it will take a slice out of the 800million tons of greenhouse gases the world's merchant fleet belches into the sky each year???

Is it important to look at the COMMERCIAL side of the saving of non-renewable fuel costs, AND also the CO2 savings aspect??? Or is global warming the main point of this development?

Answer 1

The initial cost is massive, and there's a maintenance and manpower issue that no one talks about.

As fuel prices rise, stuff like this may become more common.

    I question the safety issue, though. If something goes wrong and the kite gets into the prop, could be a real problem if the tether wraps around the shaft at the base of the prop.

As chief mate on a tanker, I can tell you that I already work 12-24 hours each and every day. I don't need more things to worry about, and neither do my crew.  I'm also the relief (fill-in) captain of a research boat, and from an operational standpoint, it's another system to worry about. Great in theory, and I hope it becomes economically viable, but have enough to do without worrying about new technology messing with my  day-to-day workload. Worrying about my boat, the idiots on her, and the weather is enough for one person.

Answer 2

It's not the wind in the sails, or kite, which pull the craft...it is the force exerted at the top of a mast which is fixed to the keel of the craft which, literally, pushes the craft through the water. The sails, attached to the top and the bottom of the mast, causes a polar moment of inertia...great enough to push the craft. It's also half the reason a sailboat, pushed past hullspeed, (boatlength divided by 1.75) expressed in knots, will dive to the bottom of the ocean.

So, my answer is 'no' to this kite theory.

I have a saiboat...ocean-going...that's my source!

Answer 3

elyslund!   what nonsense! Your formula is also way out to lunch for hull speed...try 1.34 X Sqaure Root Waterline for starters. LOOK IT UP.

Sadly you know nothing....Sorry, but you've proven it as fact, here publicly.

Now to the question at hand....

All of the aspects you mention are important....fuel savings and emissions.

The Sail will augment fuel cost and improve shipping schedules due to the fact that they will need to throttle back less for fuel savings...a current strategy. Thus they will once again, be able to speed up product delivery and revenue...theoretically.
