--“Modeling fluid flow between two surfaces lined with tiny ridges, researchers found tiny ridges actually reduce drag, allowing the for fluid to flow around in a more efficient manner….--

--I thought everybody already knew that the dimples on a golf ball make it go farther---less "drag"--

Sheer idiocy.

Reducing drag on ocean going vessels (or, more importantly aircraft, or for that matter automobiles and trucks) is a good idea because it reduces operating costs — well provided the cost of the coating or other surface preparation which does it is low enough that the operating cost reduction over the life of the vehicle exceeds the increased initial cost when calculated on a present value basis.

But I guess it’s easier to sell such things to economically illiterate lefties by telling them that it will “save the planet”.

“According to researchers at UCLA, rough surfaces lined with tiny ridges may actually reduce drag,” says the Science Recorder.

I guess none of these yahoos know why a golf ball has dimples.

Reduced drag = less fuel consumption AT A GIVEN SPEED. FAIL

Reduced drag = potentially higher speeds = SAME amount of fuel burned to reach destination sooner = lowered turn around times = same amount of fuel burned. WIN for shippers; FAIL for AGW nuts.

“Experts say the wooded areas in the region could increase by 50% over the coming decades,”

Which, were it true, would actually be a good thing.

The science of hydrodynamics has known that a rough surface such as a primer painted surface on a planing hull is faster on boats than a waxed smooth surface. This has been known for MANY years. ALL globull warming science is neither science nor global... it is just organized criminals scamming the entire Earth’s populace! Hence... GLOBULL!

I read the Daily Mail daily for laughs. I spent a couple of months in the Northern UK in the early 80’s. Even on the best days the weather sucked, The coldest winter I ever spent was a Summer in Newcastle, the beer was good though.

Now I read in the Mail that the weather has returned to 1311 and natures cycle repeats.

The scientists actually say since sea transport accounts for 4 percent of greenhouse gases, reducing drag will have “a substantial impact on global warming emissions,” because of the reduced fuel requirements with less drag.

Typical liberal lunacy. Look, if it is economical to do this to ship hulls, it will be done. By "economical" I mean that it will save you more money than it costs to do within a reasonable period of time.  It takes a lot of fuel to power a large ocean-going vessel. If operators believe they'll see significant savings from it, you can bet they'll do it. I notice the article doesn't mention how much drag is reduced, which tends to make me think the amount is trivial to the extreme.

It's probably not enough to be worth the trouble as a retrofit, but perhaps it's something that could be designed into new ships. Reduced drag = lower lifetime operational costs, and perhaps even increased speed.

A small fraction of 4% is a big deal?
Enviro nuts across the board can't see the difference between a big problem and a small problem.
Or in this case, the difference between a problem and a non-problem.

[BitWielder1]

If shippers can safe fuel, they will. Hence the bulb in the front of most modern ships.
When it becomes cost effective to texture the hull, they will.
Until then, keeping barnacles off and corrosion down is more important.

Back around 1997 we had a very warm winter. I noticed the Jonquils coming up on Jan 5 of that year.

It is now Jan 20, and no Jonquils have poked their heads through the ground yet.

We still got Feb and Mar to contend with.

“Scientists have recently discovered that rough surfaces may actually reduce the amount of friction and drag after testing the hypothesis on the microscopic level.”

Anyone, who has ever used machinists’ gauge blocks, knows that very smooth metal sticks to other very smooth metal. The stickiness is at the molecular level, and it can be very difficult to separate two pieces of very smooth, flat metal.
