TreeHugger has a post on a proposal for mitigating climate change using a form of biomimicry from Pax Scientific's Jay Harman (which I admit makes little sense to me) - A New Spin on Climate Engineering.
Jay Harman's idea of using spiral dynamics to create spinning, vortex-shaped impellers that serve as heat sinks and buy us time to avert climate changes with a clean energy economy is not new. We've chronicled Harman's biomimicry-inspired inventions before. And geoengineering's promise has yet to be realized in combating warming temperatures. Yet Pax Scientific, a company Harman helped found, is now proposing to carry out a one-year study, says a special issue of Ode, to figure out exactly how much anthropogenic warming might be offset by Harman's brand of atmospheric engineering, and at what cost.
Pax Scientific is proposing to carry out a one-year study that would use atmospheric modeling, energy scaling, and modeling of vortices to see if Harman's theory that a vortex impeller could be used to mix the atmosphere, bringing it back into balance, and providing some cooling will work.
Computer modeling had already confirmed, according to Ode, that a 747 aircraft engine could create a vortex that could redistribute energy in a sky space 6 miles by 31 miles.
Of course, there are some unknowns and dangers, the first being how to keep the vortex under some semblance of control, as if it cut loose from its source, it could wreak havoc. Harman proporses setting up a nearby vortex to cancel out the first.

The city of Cleveland is also consider some less wild uses of biomimicry -
Using the natural methods of 'biomimicry' to fix Cleveland's Cuyahoga River.
This is the last in a series of stories printed in The Plain Dealer this year as part of "The Year of the River," a recognition of the Cuyahoga River's return to health 40 years after it infamously caught fire. This story looks to new hope for bringing life to the industrial mouth of the river.
Maybe biomimicry can finish saving the Cuyahoga.
The new, nature-inspired engineering could be the source of environmental improvements to the river that runs through Cleveland -- especially in the biologically challenged, steel-lined shipping channel.
That someday is already dawning, some key river advocates say.
Biomimicry is the fast-growing field in which engineers, artists and designers are drawing more and more from natural examples of successful adaptations to solve human problems.

Jay Harman's Pax Scientific was one organisation that featured in my recent post on biomimicry. The New York Times has an article tracking his slow progress.
WHAT if someone invented a better mousetrap and the world yawned?
Until now, that has been the fate of Jay Harman, an Australian naturalist who believes that he’s found a way to use fundamental properties of physics and biology to improve the design of everything from simple fans and pumps to hydroelectric dams and aircraft.
Almost every piece of machinery in the physical world has efficiency limits related to the flow of liquids and gases: pumps consume energy to move liquids; the amount of fuel used by airplanes and cars is based on their aerodynamic efficiency; and fans and wind turbines both consume and generate energy based on the efficiency of the shape of their rotating blades.
As a young boy, Mr. Harman saw that objects in nature seemed to abhor traveling in a straight line. Fluids and gases flow in languid spirals, and although he was not trained as a scientist, it struck him as obvious that there was a profound lesson in that motion.
Ultimately, he turned the source of his childhood fascination into something he believed would be practical. He surmised that he could exploit his observations about fluids to change the shape of propellers, fans and virtually anything that needs to move in a fluid or gas environment.
After informally studying vortexes for several decades, he went to his bathtub and, with a bit of cleverness, was able to create a cast from the vortex generated by water flowing down the drain. Then he used the cast to help redesign the rotating parts, or impellers, used in pumps and other devices to move fluids. Since then he has applied his approach more broadly to redesign all kinds of devices that move fluids and gases.
Two examples of intriguing possibilities show the range of his ambitions. If the vortexes created by the wing tips of jets could be reduced or eliminated, it would be possible to space commercial aircraft more closely together, greatly improving the efficiency of airplanes and airports. Mr. Harman believes he has a technological approach that does just that.
In an entirely different arena, Mr. Harman’s impeller can be used in combination with a solar-powered motor to create a ripple effect on the surface of a pool of stagnant water, changing the balance of nitrogen and oxygen in the pool. This makes it possible to interrupt the development of mosquito larvae, potentially reducing the threat of malaria and encephalitis.
Mr. Harman is a practitioner of biomimicry, a growing movement of the industrial-design field. Eleven years ago, he established Pax Scientific to commercialize his ideas, thinking that it would take only a couple of years to convince companies that they could increase efficiency, lower noise or create entirely new categories of products by following his approach.
It has been a longer and more circuitous path than he first imagined. Despite glowing publicity and a remarkably photogenic technology, Pax Scientific has not been an overnight success. “When I started I thought that this would take 6 to 12 months,” Mr. Harman said. What he found instead were companies that had little interest in redesigning their products, even in the face of the promise of double-digit increases in efficiency.
His radical ideas have so far found a cautious reception in the aircraft, air- conditioning, boating, pump and wind turbine industries. Mr. Harman’s experience is not unusual. Rather than beating a path to the door of mousetrap designers, the world seems to actively avoid them.
Indeed, one of his advisers, Paul Saffo, an independent Silicon Valley technology forecaster, often repeats this simple dictum: “Never mistake a clear view for a short distance.” Even in fields such as the computer industry, which celebrates innovation, systemic change can be glacial. ...
THE slow uptake on his ideas about streamlining fluid flow hasn’t deterred Mr. Harman, who pronounces himself an incurable optimist.
“There is a basic psychology of the human species which is resistant to change,” he said, “but it’s not in my DNA to give up.”
And things appear to be turning his way.
With the help of the entrepreneur and environmentalist Paul Hawken, he has established a subsidiary, PaxIT, that is designing quieter and more energy-efficient fans for the computer industry. It is one of a series of five spin-off businesses that Mr. Harman has created to pursue different industries. The Pax design will begin to show up in consumer products within the next year, Mr. Harman said.
In March, the venture capitalist Vinod Khosla made a significant investment in Pax Streamline, founded to pursue a new generation of wind turbines and air-conditioning systems.
In another hopeful sign, a world that long ignored energy efficiency is suddenly thinking of nothing else. “We tried for years to promote energy conservation, and we couldn’t find one who was interested,” he said. “Now the world has done a U-turn.”
