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..."

Light at the end of the tunnel - LED based technology brings artificial sunlight into closed rooms

Light at the end of the tunnel - LED based technology brings artificial sunlight into closed rooms | Cool Future Technologies | Scoop.it

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

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.

British inventor develops Hoverbike, a motorcycle that takes to the skies

British inventor develops Hoverbike, a motorcycle that takes to the skies | Cool Future Technologies | Scoop.it

Mr Malloy, the inventor who works a day job at an optical engineering firm in Sydney, has spent the last two years working in his garage on a bike that can take to the air.


With a maximum takeoff weight of 270kg, the Hoverbike is projected to reach an airspeed of 150 knots (278 km/h) and travel 148km on a primary tank of fuel at 80knts cruise (290km with secondary tanks installed), according to his website.


The original intention was to get the Hoverbike free flying and "show that to the world and get potential investors to invest to take it towards the production stage, which is harder than the flying stage". But this proved financially impossible. 


So for now, a 1/3rd size prototype is being developed that can be used as a drone. There is a Kickstarter campaign that will run until the end of August and has already reached its funding goal.

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 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."

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.

Salt Water Powered Car Gets European Approval

Salt Water Powered Car Gets European Approval | Cool Future Technologies | Scoop.it

With salt water as its fuel, which it converts to electricity, it has a top speed of over 200 mph and has now been approved for public road use in Europe.


A car which uses an electrolyte flow cell power system is now certified for use on European roads. The car is called the Quant e-Sportlimousine, which made its debut at the 2014 Geneva Motor Show.


Not only can this car run on salt water, but it is claimed that the car has peak power of 920 horsepower (680 kW), 0-62 mph (100 km/h) in 2.8 seconds and a top speed of 217.5 mph (350 km/h).


“The power density of the nanoFLOWCELL® at 600 W per kilogram or per litre is greater than any comparable system; five times greater, to be specific. That means you can drive five times further with our system than you can with a conventional battery system, including the most state-of-the-art lithium-ion batteries. The system is also extremely safe to operate and environmentally friendly. Most importantly, since there are almost no moving parts and it produces negligible waste heat, it has an efficiency of more than 80%. There has never been anything like it.”

Scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis.


The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas. Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive and abundant nickel and iron.


"Using nickel and iron, which are cheap materials, we were able to make the electrocatalysts active enough to split water at room temperature with a single 1.5-volt battery," said Hongjie Dai, a professor of chemistry at Stanford.


"This is the first time anyone has used non-precious metal catalysts to split water at a voltage that low. It's quite remarkable, because normally you need expensive metals, like platinum or iridium, to achieve that voltage."

IBM Solar Collector Magnifies Sun By 2000X – These Could Provide Power To The Entire Planet | The Unbounded Spirit | Cool Future Technologies | Scoop.it

A team at IBM recently developed what they call a High Concentration Photo Voltaic Thermal (HCPVT) system that is capable of concentrating the power of 2,000 suns, they are even claiming to be able to concentrate energy safely up to 5,000X, that’s huge.


The process of  trapping the sunlight produces water that can be used to produce filtered drinkable water, or used for other things like air conditioning etc. Scientists envision that the HCPVT system could provide sustainable energy and fresh water to communities all around the world.


“Each 1cmX1cm chip can convert 200-250 watts, on average, over a typical eight-hour day in a sunny region.


In the HCPVT system, instead of heating a building, the 90 degree Celsius water will pass through a porous membrane distillation system where it is then vaporized and desalinated.


Such a system could provide 30-40 liters of drinkable water per square meter of receiver area per day, while still generating electricity with a more than 25 percent yield or two kilowatts hours per day.
