Scientists have recently discovered that rough surfaces may actually reduce the amount of friction and drag after testing the hypothesis on the microscopic level.
“According to researchers at UCLA, rough surfaces lined with tiny ridges may actually reduce drag,” says the Science Recorder. “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….This is not the first time scientists have sought to create models based on rough ridges to reduce drag. However, advances in technology now allow scientists to create models on a microscopic level.”
Yes, but it’s the first time that the testing has been linked to global warming.
Of course by now we should know that EVERYTHING eventually relates to global warming.
Or income inequality.
So, anywho: Scientists says that by reducing drag on sea-going vessel less fuel will be need… and therefore…she’s a WITCH!
OK, not really.
But almost.
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.
Hey, when you are reaching for straws even a fraction of 4 percent reduction is a “substantial” amount-- especially when the Chinese are ratcheting up output of greenhouse gases way past the 4 percent mark.
And that is what confuses me about the science behind greenhouse gases and global warming, especially as it applies to policy.
Years ago I offered to shave my head bald and eat a can of dog food if someone—anyone-- could show me a credible scientific paper that demonstrates how the earth would cool even a fraction of a degree Fahrenheit by enacting a carbon tax here in the United States, such as the one proposed by the Democrats in 2009 and 2010.
I’m still waiting.
Because one would suppose that in policies promoted by properly-thinking, modern progressives-- who worship all things science— and have no time for mumbo jumbo about faith and religion, that at the very least they’d have data to support that their policies will cool the earth, solve world hunger, bring people out of poverty, improve education, create income equality, or pay female White House staffers commensurate with men.
OK, the last one was outrageous. Never gonna happen under Obama.
What was I thinking?
At the very least, I was thinking that people like Ericynot, BoatBoy, DoctorRoy or Hillinger would enjoy me being bald and eating dog food.
Heck, I’d even make a video of it.
But the problem remains: Sea levels aren’t rising, storms aren’t nastier and more brutish. The only science that’s being done is the type where estimates are used where data is called for and predictions are being used instead of conclusions.
Stumped by the fact that temperatures are not accurately reflecting current climate “models”- in fact temperatures have remained stable for 17 years- scientists on the government gravy train are trying to tie any weather event to so-called climate change.
Or income inequality. Which really?Aren’t they the same things?
Hurricanes? Global warming.
Tornadoes? Global warming?
Drought? Global warming?
Blizzards, dropping temperatures, meteorites, Big Gulps? Global warming.
Last year I documented how researchers made up a map showing how vegetation could change in the arctic because of global warming.
The map, no lie, was called the “most accurate map” ever produced of its type.
A long last, scientists have revealed the single most important document ever, I wrote.It’s a crayon-colored map showing how “trees” could grow in the arctic.
If finally, mercifully, any one of the so-called “climate models” that so far have failed to “model” climate accurately, suddenly and then accurately begin to “model” climate in real time, then, well, WOW!
“Experts say the wooded areas in the region could increase by 50% over the coming decades,” writes the UK’s Daily Mail, “and accelerate global warming in the process. Researchers have unveiled the most accurate map ever (!) of how vegetation could change in the region.”
In the meantime,ThinkProgresshas published a remarkable paper calledArctic Sea Ice Death Spiral And Cold Weatherthat proves, or at least,says- same thing if you are a liberal - that globalwarmingis to blame for …coldweather in Germany.

Even homosexuality has been tied to global warming via population control.
“With the natural world on the brink of demise largely because of overpopulation,” G. Roger Denson, a self-appointed social theoretician wrote on the Huffington Post,“unrestrained homosexuality, as one of a variety of ethical and democratic measures available to us today, offers perhaps the most natural option to be enjoined.”
Unrestrained gayness?
Seriously?
Going in through the out door with another man doesn’t seem “the most natural option to be enjoined” in trying to cool down the earth’s atmosphere.
But in the interest of fairness if G. Roger Denson wants to produce an actual scientific paper proving me wrong, I got a can of dog food and clipping shears here waiting.
--I thought everybody already knew that the dimples on a golf ball make it go farther---less "drag"--
—I thought everybody already knew that the dimples on a golf ball make it go farther-—less “drag”—
Would strategically placed dimples on aircraft wings also reduce drag ?
Dry dog food tastes like dirt.
Remember that a golf ball is most likely spinning, whereas a wing, even on a helicopter, is relatively stable to the air.
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”.
Venturi effect
Yes, but part of that “drag” is lift.
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.
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!
Now I read in the Mail that the weather has returned to 1311 and natures cycle repeats.

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.
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.
