Wind Turbines Inspired by Insect Wings are 35% More Efficient

Wind Turbines Inspired by Insect Wings are 35% More Efficient | Biomimicry | Scoop.it

"Wind turbines produce 4% of the planet’s energy, but they only work well when the wind is blowing just right. Now, by drawing inspiration from the flexible wings of insects, scientists have found a way to make wind turbine blades 35% more efficient at producing energy. If commercialized, the advance could make this green technology a more viable alternative to fossil fuels in the coming years."

Another interesting example of design evolution. Those blades provide a good compromise between drag and net torque. It is a finite-size system which design is evolving to facilitate the flow of energy from the wind to a rotating axis.

Bionic Leaf Makes Fuel from Sunlight, Water and Air

Bionic Leaf Makes Fuel from Sunlight, Water and Air | Biomimicry | Scoop.it
A tree's leaf, a blade of grass, a single algal cell: all make fuel from the simple combination of water, sunlight and carbon dioxide through the miracle of photosynthesis. Now scientists say they have replicated—and improved—that trick by combining chemistry and biology in a "bionic" leaf.

Bees Could Engineer Next-Generation Energy Storage | Biomimicry | Scoop.it

"Energy storage could be the next item on the list when it comes to listing all the reasons we need to save the world's bee population from collapse. A research team at Purdue University has found that bee pollen can be used as an efficient, renewable source for anodes in lithium-ion batteries. The team also tested pollen sourced directly from cattails and got even more encouraging results."

Wind Turbines With Owl Wings Could Silently Make Extra Energy

Wind Turbines With Owl Wings Could Silently Make Extra Energy | Biomimicry | Scoop.it

"Moving silently through the air is not just for the birds. Wind farms inspired by the stealthy flight of owls could generate more energy without annoying those who live nearby, say researchers."

Altin Pevqeli's curator insight, September 14, 2015 10:26 PM

If they did make turbines inspired by the flight of owls which is silent, it would be a tremendous job. It would solve one of the biggest problems of turbine which is noise. If there isn't much noise people wouldn't mind them, making it so people could build more in areas.

Tree-shaped Wind-turbines Shows Biomimicry at its Best

Tree-shaped Wind-turbines Shows Biomimicry at its Best | Biomimicry | Scoop.it

"... a French company called NewWind has been developing aesthetically pleasing, tree-shaped turbines meant to run silently within cities, at ground level. The innovation is simple named “L’Arbre à Vent” or in English “The Wind Tree”. The tree features 72 artificial leaves where each leave is a small turbine that rotates around a vertically directed axis. The leaves are very light-weight, which means that they can generate power from very small amounts of wind. Actually it takes nothing more than 4.4 mph (2 meters/second) of wind for them to function, and this is amount of wind is equal to a gentle breeze."

Nature's Solutions for Energy Shortages

Nature's Solutions for Energy Shortages | Biomimicry | Scoop.it
 Energy efficiency in living things often means combining material and fuel recycling with hitching a free ride. Soaring birds, drifting larvae and even prairie dogs make use of dependable physical forces in order to survive with the least amount of expended energy. Putting these principles into practice, however, demands a deep knowledge of the processes involved.

"The great artist Leonardo Da Vinci once said, “Those who are inspired by a model other than Nature, a mistress above all masters, are laboring in vain.” The developing field of biomimicry seeks to learn from “the world’s greatest teacher” by modeling technology after organism’s unique features.  This form of engineering is now being applied to the world of renewable energy sources as shown in two of the devices discussed below: BioSTREAM, a tidal energy device, and turbine blade tubercles, a wind harnessing device."

First Practical "Artificial Leaf" Powers Fuel Cells for Rural Homes

First Practical "Artificial Leaf" Powers Fuel Cells for Rural Homes | Biomimicry | Scoop.it

Scientists have long been trying to mimic the photosynthesis perfected by leaves -- turning sunlight and water into energy that can be stored. While many have made attempts, there seems to be one group of scientists that have pulled it off. The news comes from the 241st National Meeting of the American Chemical Society, where the researchers made their announcement. The "artificial leaf" would be used to generate power for off grid homes in developing areas, and the hope is that one such "leaf" could provide enough energy for an entire household.

"The gentle swaying of kelp forests belies the immense hydraulic pressures they've evolved to endure. The waves that crash over them transfer huge amounts of energy—an average of 36kW/m with three-foot swells. Now, a green energy firm (BioPower) is banking on this sway to run arrays of Megawatt generators of the coast of Victoria."

New Batteries That Mimic the Human Intestine Could Store 5 Times More Energy

New Batteries That Mimic the Human Intestine Could Store 5 Times More Energy | Biomimicry | Scoop.it
Scientists have developed a new prototype battery inspired by the anatomy of the human intestine, and the biologically informed approach could pave the way for much more powerful energy sources for our digital devices.

The prototype – which offers up to five times the energy density of the lithium-ion batteries we use in smartphones and laptops – uses a lithium-sulphur cell instead, and its intestine-mimicking design could finally make these energy-dense batteries long-lasting enough for commercial use.

Moth Eyes, Lotus Leaf Biomimicry To Boost Solar Efficiency

Moth Eyes, Lotus Leaf Biomimicry To Boost Solar Efficiency | Biomimicry | Scoop.it

The atomic structure of a moth’s eye and lotus leaves have inspired scientists to create a new glass coating that could increase the efficiency of solar panels by up to six per cent. “While lotus leaves repel water and self-clean when it rains, a moth’s eyes are antireflective because of naturally covered tapered nanostructures where the refractive index gradually increases as light travels to the moth’s cornea,” said Tolga Aytug, member of ORNL’s Materials Chemistry Group. “Combined, these features provide truly game-changing ability to design coatings for specific properties and performance.”"

"Have you noticed the tiny contours and crinkles on the surface of a leaf? All those folds bend and absorb light better than if it was flat, helping it receive more rays. It turns out, this same advantageous trait inspired engineers at Princeton University to use similar micro-folds to improve the efficiency of plastic solar cells in solar panels. These man-made energy-collectors are one example of the growing field of engineering known as biomimicry."

Indeed, scientists have been slaving away for years on a lithium-ion battery with a longer lifespan. But who would’ve thought that the inspiration for the most promising new design would come from inside a pomegranate?"

Interesting ideas, though being inspired by tornadoes and hurricanes should be 'meteomimicry'. Also, I've always found bird's two phase lungs a more interesting model than their feet.

Biomimicry: Inspiring Solar Energy Technology Developments Through Nature

Biomimicry: Inspiring Solar Energy Technology Developments Through Nature | Biomimicry | Scoop.it

The improvements to solar energy technology have been impressive, such as going from the conventional and bulky first generation solar cells/modules to the flexible second generation thin-film solar cells/modules. Accompanying this has been a significant reduction in the cost of manufacturing solar cells and modules, with an average price of roughly US$1 per Watt for first-generation and second-generation modules.

 

With further technological breakthroughs expected in the next few years, the future is rosy for the solar industry. However, instead of patiently waiting for this next wave of advancements, academics have devised ways to further tweak solar energy technology and these tweaks are based on observations in nature.
