Clean Solar Thermal Energy Technology with No Moving Parts – Thermoacoustic Stirling Engine (w Video 4min)

Clean Solar Thermal Energy Technology with No Moving Parts – Thermoacoustic Stirling Engine (w Video 4min) | Cool Future Technologies | Scoop.it

The Thermoacoustic Stirling Engine or TASE for short is an evolution of the classical Stirling Engine which is a high efficiency conversion technology for producing electricity from Kinetic motion from a thermal source.


A 1.5 MW field in Tooele UT with couple of more pilot fields, all have been operational for a few years.


Key Features of the pilot projects include:


1) High solar-to-grid efficiency
2) 3.5/7.5 kWe units, scalable to several MW
3) Low visual impact and no earthworks required
4) Low water usage, only mirror cleaning
5) Easy to hybridize with natural gas or biogas


Qnergy recently claims to have set a new world record, using acoustic waves created by solar heat to produce 1 kW of electrical power during a field test completed at its test facility in Ogden, Utah.

89-Year-Old Man Develops Bladeless Bird-Friendly Wind Turbine!

89-Year-Old Man Develops Bladeless Bird-Friendly Wind Turbine! | Cool Future Technologies | Scoop.it

Green’s CWP Compressed Air Enclosed Wind Turbine completely eliminates the three massive blades seen on most wind turbines. 


Rather than waiting for the wind to turn a blade, Green’s device features a patented Inner Compression Cone Technology, which he claims will squeeze and compress the incoming air in order to create more power at the turbine.


“Our design does not have any external moving parts to hit the birds,” writes Green on his website. “Our unit is easy to see so the birds can avoid it, and all moving parts are internal."

Incredible 3D Printing Technique Looks Like Sci-Fi

Incredible 3D Printing Technique Looks Like Sci-Fi | Cool Future Technologies | Scoop.it

You've never seen a 3D printer like this


Think of the old way of 3D printing as a kind of plastic (or sometimes metal or biological) pancake stacking factory.

Layers of polymer are laid down—sometimes preheated, sometimes hardened by laser light. It's slow (even small objects can take hours) and what comes out is pretty weak thanks to all those layers. 


"In many ways, traditional 3D printing is actually 2D printing over and over again," said DeSimone. "But we actually grow parts continuously out of liquid resin puddle, and can do it really, really fast, at hundreds to thousands of millimeters an hour."

Sepp Hasslberger's insight:

Here is a real advance in 3D printing 

No longer is the object made of layer deposited above layer, it's grown continuously speeding up the process and making the final object more "real"

World’s first grid-connected wave power station switched on in Australia

World’s first grid-connected wave power station switched on in Australia | Cool Future Technologies | Scoop.it

The world’s first grid-connected wave power station has been activated off the coast of Western Australia (WA).


After more than a decade of testing and demonstrations, Australian company Carnegie Wave Energy has switched on a pilot project that has begun feeding wave-generated electricity into a local WA grid.   

The company says its system is “different from other wave energy devices as it operates under water where it is safer from large storms [and corrosion] and invisible from the shore”.   


The round, submerged buoys are tethered to seabed pump units, which are installed at a depth of between 25 and 50 metres. Waves crashing into the buoys drive the pumps, which push pressurised seawater through a pipeline beneath the ocean floor to an onshore hydroelectric power station. Here, the high-pressure water drives a turbine and generates electricity. 


“The high-pressure water can also be used to supply a reverse osmosis desalination plant..."

Electricity is one of the most important things in the world. Without it. The world stop. People always seek for safe and green power source. Form the Dam, fossil-fuel, Solar cell or even nuclear, these power source has its own limit and risks. How about the infinite power source, the one that can fit into mobile phone and run for years without recharging? same goes for cars, electronics devices. Hmm maybe next 100 years?

There’s good news for the Scandinavians, and indeed anyone who suffers from a lack of daylight in their physical environment.


Pioneering new technology from Italy has succeeded in creating realistic artificial daylight where so many past attempts haven’t quite worked.

The invention, known as Coelux, is the brainchild of physicist Professor Paolo Di Trapani of Italy’s University of Insubria, and has taken 10 years to perfect. In an interview with lighting trade journal Lux Magazine he explains: “The difference between Coelux and other attempts to recreate the sky is that it rebuilds the natural phenomenon of a natural sky, rather than just trying to look like it.”

Octopus robot makes waves with ultra-fast propulsion

Octopus robot makes waves with ultra-fast propulsion | Cool Future Technologies | Scoop.it

Scientists have developed an octopus-like robot, which can zoom through water with ultra-fast propulsion and acceleration never before seen in man-made underwater vehicles.


The 30cm long self-propelling robot is inflated with water and then rapidly deflates by shooting the water out through its base to power its outstanding propulsion and acceleration, despite starting from a non-streamlined shape. As the rocket contracts, it can achieve more than 2.6 times the thrust of a rigid rocket doing the same manoeuvre.

The robot is capable of accelerating up to ten body lengths in less than a second. In recent laboratory tests, the robot accelerated a one kilogram payload up to 6mph in less than a second.

How Solar Power Could Slay The Fossil Fuel Empire By 2030

How Solar Power Could Slay The Fossil Fuel Empire By 2030 | Cool Future Technologies | Scoop.it

Above: Abengoa Solar's Solnova Solar Power Station


In just 15 years, the world as we know it will have transformed forever. The age of oil, gas, coal and nuclear will be over.


A new age of clean power and smarter cars will fundamentally, totally, and permanently disrupt the existing fossil fuel-dependent industrial infrastructure in a way that even the most starry-eyed proponents of ‘green energy’ could never have imagined.  


“We are on the cusp of the largest disruption of industry and society since the first industrial revolution. Large, centralized, top-down, supplier-centric energy is on its way out. It is being replaced by modular, distributed, bottom-up, open, knowledge-based, consumer-centric energy,” said Seba. “The transition has already started and the disruption will be swift. Conventional energy sources are already obsolete or soon to be obsolete.”

Scientists predict green energy revolution after incredible new graphene discoveries | Cool Future Technologies | Scoop.it

Researchers have discovered that graphene allows positively charged hydrogen atoms or protons to pass through it despite being completely impermeable to all other gases, including hydrogen itself.


The implications of the discovery are immense as it could dramatically increase the efficiency of fuel cells, which generate electricity directly from hydrogen, the scientists said.


The breakthrough raises the prospect of extracting hydrogen fuel from air and burning it as a carbon-free source of energy in a fuel cell to produce electricity and water with no damaging waste products.

This device diagnoses diseases from a single drop of blood | Cool Future Technologies | Scoop.it

Tech giants are jumping into the fray with fitness offerings like Apple Health and Google Fit, but there’s still not much in the way of, well, actual medicine.


Dr. Eugene Chan and his colleagues at the DNA Medical Institute (DMI) aim to change that. Chan's team has created a portable handheld device that can diagnose hundreds of diseases using a single drop of blood with what Chan claims is gold-standard accuracy.


Known as rHEALTH, the technology was developed over the course of seven years with grants from NASA, the National Institutes of Health, and the Bill and Melinda Gates Foundation.


"There used to be no method for good, autonomous diagnosis," Chan tells WIRED. "rHEALTH technology is highly sensitive, quantitative, and capable of meeting the FDA's bar for sophistication, while still being geared for consumers."

3-D Printed Car: Local Motors “Strati” 3-D printed roadster

3-D Printed Car: Local Motors “Strati” 3-D printed roadster | Cool Future Technologies | Scoop.it

Welcome to the “Strati,” the world’s first 3-D printed car. Developed and built by Phoenix-based Local Motors, this 2-passenger roadster has the looks of a dune buggy, and the technology you’d expect from a sci-fi novel.


The Daily News Autos ventured to Brooklyn, New York, to see this car first-hand and get a ride in a vehicle that could reshape how cars are designed, built, bought, sold, and then recycled…only to be re-designed and rebuilt all over again!


Built of carbon fiber-reinforced thermoplastic, the Strati tips the scales at about 1,800 lbs. The Strati’s entire body and four fenders are printed, with the build process presently taking 44 hours.


You can’t print engines, suspension parts, gearboxes or tires, however. So that means the mechanical bits of the Strati had to come from somewhere else. In this case, the powertrain comes from the Renault Twizy, a quirky tandem-seat electric car not sold in the U.S.

Simin Qiu, a student at London’s Royal College of Art, has invented a unique water faucet that uses the laws of physics to save water.


Qiu was inspired by the many sacred spirals that exist in nature, in plants, shells and many other examples of natural spiraling phenomena. Qiu also noticed that water spiraled in nature in many circumstances, especially when in a pipeline.


Researching further, Qiu found that water actually slows down while in a spiral or pipeline, so he set out to create a water faucet that would create a spiral, and hopefully save water...

Silent, tree-shaped wind turbines to debut in Paris | Cool Future Technologies | Scoop.it

Wind-generated power has the potential to make a huge contribution to varying renewable energies around the globe, but the issue of where turbines are built can be a big issue for some communities, or even countries.


When wind turbines can't be built off-shore, some places feel constructing them on land ruins the scenery of the landscape, takes up too much space, or generates too much noise. Enter France's NewWind, which has been developing aesthetically pleasing, tree-shaped turbines meant to run silently within cities, at ground level.


Dubbed the Wind Tree, NewWind's turbines measure 36 feet (11 meters) tall and around 26 feet (8 meters) in diameter, and feature 72 artificial leaves. Each leaf is actually a small turbine that rotates while in a vertical position. Due to their light weight material, they can spin enough to generate power with as little as 4.4 mph (2 meters/second) of wind; nothing more than a gentle breeze.

A Spoonful of This New Material Can Suck Up a Whole Roomful of Oxygen

A Spoonful of This New Material Can Suck Up a Whole Roomful of Oxygen | Cool Future Technologies | Scoop.it

A team of scientists in Denmark just invented a crystalline material that can absorb oxygen with astounding efficiency.


How astounding? Well, a single spoonful of the stuff can suck all of the oxygen out of a room.


The best part is that it can release it again with just a little bit of heat. Say goodbye to bulky oxygen tanks.


"The material can absorb and release oxygen many times without losing the ability. It is like dipping a sponge in water, squeezing the water out of it and repeating the process over and over again," says Professor Christine McKenzie who led the research.


"When the substance is saturated with oxygen, it can be compared to an oxygen tank, containing pure oxygen under pressure. The difference is that this material can hold three times as much oxygen."

Scottish Researchers claim hydrogen energy advance

Scottish Researchers claim hydrogen energy advance | Cool Future Technologies | Scoop.it

Researchers at Glasgow University have claimed a breakthrough in producing hydrogen fuel from water. 


They said their process is fast, clean and cheap. It can store energy from the sun and wind.


Writing in the journal Science, the Glasgow researchers said their process is thirty times faster than the current method.


Without using any more energy, it is claimed to store the hydrogen in a carbon-free liquid.


Prof Lee Cronin, of the university's School of Chemistry. said: "The process uses a liquid that allows the hydrogen to be locked up in a liquid-based inorganic fuel.

Sepp Hasslberger's insight:

This looks like an important advance ... with it, hydrogen becomes a useable way to store excess electricity production for later use.
