Twisting Radio Waves Could Give Us 100x More Wireless Bandwidth

Twisting Radio Waves Could Give Us 100x More Wireless Bandwidth | Cool Future Technologies | Scoop.it

The idea is to twist radio waves like corkscrews and create multiple subfrequencies, distinguished by their degree of twistedness. Each subchannel carries discrete data sets. “You can tune the wave with a given frequency as you normally do, but there is also a fingerprint left by the twist,” Tamburini says. He and Swedish colleague Bo Thidé hit upon the approach while studying waves warped by the immense gravity of black holes. This past June, the scientists set up a custom dish in Venice and successfully broadcast video encoded in both twisted and normal radio waves across St. Mark’s Basin.

Cold fusion reactor independently verified, has 10,000 times the energy density of gas

Cold fusion reactor independently verified, has 10,000 times the energy density of gas | Cool Future Technologies | Scoop.it

Against all probability, a device that purports to use cold fusion to generate vast amounts of power has been verified by a panel of independent scientists.


The cold fusion device being tested has roughly 10,000 times the energy density and 1,000 times the power density of gasoline. 


If Rossi and Focardi’s cold fusion technology turns out to be real — if the E-Cat really has 10,000 times the energy density and 1,000 times the power density of gasoline — then the world will change, very, very quickly.

The coming era of unlimited — and free — clean energy

The coming era of unlimited — and free — clean energy | Cool Future Technologies | Scoop.it

In places such as Germany, Spain, Portugal, Australia, and the Southwest United States, residential-scale solar production has already reached “grid parity” with average residential electricity prices.  In other words, it costs no more in the long term to install solar panels than to buy electricity from utility companies.  


The prices of solar panels have fallen 75 percent in the past five years alone and will fall much further as the technologies to create them improve and scale of production increases.  


By 2020, solar energy will be price-competitive with energy generated from fossil fuels on an unsubsidized basis in most parts of the world.  Within the next decade, it will cost a fraction of what fossil-fuel-based alternatives do. 


It isn’t just solar production that is advancing at a rapid rate; there are also technologies to harness the power of wind, biomass, thermal, tidal, and waste-breakdown energy, and research projects all over the world are working on improving their efficiency and effectiveness. 


Wind power, for example, has also come down sharply in price and is now competitive with the cost of new coal-burning power plants in the United States...

3D-printed eco-friendly supercar does 0-60 in 2 seconds

3D-printed eco-friendly supercar does 0-60 in 2 seconds | Cool Future Technologies | Scoop.it

Divergent Microfactories (San Francisco, CA), a company aimed at revolutionizing automotive manufacturing, has unveiled a 3D-printed prototype supercar designed to illustrate the potential for eco-friendly manufacturing of cars.


Designed and built using the company's 3D-printing-based Node Technology Platform, the prototype - called Blade - is offered as "one of the greenest and most powerful cars in the world."


Powered by either compressed gas or gasoline and equipped with a four-cylinder rear-mounted 700-horsepower engine, Blade goes from 0-60 mph in about two seconds and weighs 1,388 lb. 


The key technology building block behind Blade is a 3D-printed aluminum alloy joint - called a "node" - that connects pieces of carbon fiber tubing to make up the car's chassis.

Sepp Hasslberger's insight:

Electric cars and hybrids aren't the most eco-friendly apparently. There is much pollution inherent in all the materials needed.

New Piezo Crystals Harness Sound Waves to Generate Hydrogen Fuel

New Piezo Crystals Harness Sound Waves to Generate Hydrogen Fuel | Cool Future Technologies | Scoop.it

It sounds like a strange combination: zinc oxide crystals, water, and noise pollution. But scientists at the University of Wisconsin-Madison have discovered that the mix can efficiently produce hydrogen without the need for a dirty catalyst like oil. By submerging a new type of zinc oxide crystal in water, the scientists claim to be able to harvest hydrogen using vibrations from passing traffic and crashing waves.

To generate the clean hydrogen, researchers produced zinc oxide crystals that absorb vibrations when placed in water. The vibrations cause the crystals to develop areas with strong positive and negative charges–a reaction that rips the surrounding water molecules and releases hydrogen and oxygen.

The mechanism, dubbed the piezoelectrochemical effect, converts 18% of energy from vibrations into hydrogen gas (compared to 10% from conventional piezoelectric materials). And since any vibration can produce the effect, the system could one day be used to generate power from anything that produces noise — cars whizzing by on the highway, crashing waves in the ocean, or planes landing at an airport.


That sounds like a good deal to us!

How To Build A Home Fusion Reactor

How To Build A Home Fusion Reactor | Cool Future Technologies | Scoop.it

The tale of a teen physics prodigy


The Boy Who Played With Fusion had its beginnings in 2010 when, as a contributing editor at PopSci, I discovered a small and unusual community of makers, high-energy hobbyists who were taking on both the formidable theory and the precision engineering of applied nuclear science.


The idea that self-taught amateurs outside the Big Science world of billion-dollar laboratories were tinkering with nukes—fusing atomic nuclei, transmuting elements, constructing atom-smashing machines in DIY laboratories—was both intriguing and unsettling.


In a way, the amateur nuclear fusion movement began at the intersection of science and science fiction. In the mid-1990s, an electrical engineer and aspiring science-fiction writer named Tom Ligon heard that the physicist Robert Bussard was living and working just two miles from his Virginia home. 


“Some people still think Bussard is a fictional character,” Ligon says, “but it turns out that he was quite real.”


Sepp Hasslberger's insight:

Fascinating how there is a whole network of makers who have self-organised to "peer review" each others' fusion reactors. They have a dedicated site that serves as a communication channel.

There are several of those researchers who have achieved fusion on table-top devices, while our science establishment with billion dollar funding can't make a proper reactor...

Revealing the ancient Chinese secret of sticky rice mortar

Revealing the ancient Chinese secret of sticky rice mortar | Cool Future Technologies | Scoop.it

Scientists have discovered the secret behind an ancient Chinese super-strong mortar made from sticky rice, the delicious 'sweet rice' that is a modern mainstay in Asian dishes. They also concluded that the mortar ― a paste used to bind and fill gaps between bricks, stone blocks and other construction materials ― remains the best available material for restoring ancient buildings.

Bingjian Zhang, Ph.D., and colleagues note that construction workers in ancient China developed sticky rice mortar about 1,500 years ago by mixing sticky rice soup with the standard mortar ingredient. That ingredient is slaked lime, limestone that has been calcined, or heated to a high temperature, and then exposed to water. Sticky rice mortar probably was the world's first composite mortar, made with both organic and inorganic materials.


The mortar was stronger and more resistant to water than pure lime mortar, and what Zhang termed one of the greatest technological innovations of the time. Builders used the material to construct important buildings like tombs, pagodas, and city walls, some of which still exist today. Some of the structures were strong enough to shrug off the effects of modern bulldozers and powerful earthquakes.

Sepp Hasslberger's insight:

Something from the past ... perhaps worth reviving. An exceptionally strong lime-based mortar mixed using rice as a strengthening ingredient. 


"Their research identified amylopectin, a type of polysaccharide, or complex carbohydrate, found in rice and other starchy foods, as the "secret ingredient" that appears to be responsible for the mortar's legendary strength.


Perhaps instead of burning all that corn for fuel, we could make more durable buildings with it...

Portland To Generate Electricity From Turbines Installed In City Water Pipes

Portland To Generate Electricity From Turbines Installed In City Water Pipes | Cool Future Technologies | Scoop.it

Water flowing through the city's pipes will generate electricity like a dam with none of the environmental consequences...


Portland has replaced a section of its existing water supply network with Lucid Energy pipes containing four forty-two inch turbines. As water flows through the pipes, the turbines spin and power attached generators, which then feed energy back into the city’s electrical grid. Known as the “Conduit 3 Hydroelectric Project,” Portland’s new clean energy source is scheduled to be up and running at full capacity in March.


...the system does more than simply provide electricity: It can monitor both the overall condition of a city’s water supply network as well as assess the drinking quality of the water flowing through it.

New materials design could dramatically boost efficiency of low-cost solar panels

New materials design could dramatically boost efficiency of low-cost solar panels | Cool Future Technologies | Scoop.it

A new material design could make low-cost solar panels far more efficient by greatly enhancing their ability to collect the sun’s energy and release it as electricity. 


"In photosynthesis, plants that are exposed to sunlight use carefully organized nanoscale structures within their cells to rapidly separate charges -- pulling electrons away from the positively charged molecule that is left behind, and keeping positive and negative charges separated," said Sarah Tolbert, a UCLA professor of chemistry and one of the senior authors of the research. "That separation is the key to making the process so efficient." 


The UCLA-developed system is composed of strands of a polymer, the building block of plastics, that absorb sunlight and pass electrons to a fullerene, a spherical carbon molecule also known as a "buckyball." 


The fullerenes inside the structure take electrons from the polymers and toss them to the outside fullerenes, which can effectively keep the electrons separated from the polymer for weeks...

Long time charge separation in photovoltaic cells ... these research results could make future solar cells both cheaper and more efficient.

Okay, this process has a lot of potential. The next phase is to take the separated chemicals and introduce them into a functioning engine, or turbine for creating electricity.

 

I'm not a scientist (per se') but if this process could be connected to a small electric engine that in turn could be connected to a generator that would produce sufficient current to power the electric engine, then the excess power could be stored, or diverted for other uses.

 

The question not revealed in this article is whether or not there was anything special about the water source...or could we use say, sea water? I'd be interested to learn if anyone has looked at the 'other' side of this energy equation, specifically, scaling up to engines capable of transporting people (and stuff) over long distances at speed?

A Drive In The Controversial e-Carriage That Could Replace Horse Drawn Carriages in Manhattan

A Drive In The Controversial e-Carriage That Could Replace Horse Drawn Carriages in Manhattan | Cool Future Technologies | Scoop.it

Jason Wenig is a car nut caught in the middle of a political battle over the potential banning of horse drawn carriages in Manhattan's Central Park. He created a nine-seater e-Carriage at the behest of New Yorkers for Clean, Livable, Safe Streets (NYCLASS) as a potential replacement.


The front-mounted electric motor runs off of lithium iron phosphate batteries and drives the rear wheels. Total output is 84 horsepower and 180 pounds-feet of torque. Top speed is electronically limited to 25 miles per hour.


Total range is about 100 miles—more than enough for a full day of carting sightseers around Central Park’s three-mile loop, Wenig says. The batteries take about six hours to charge from empty using a 220-volt outlet (the kind used to power major appliances).

The chassis and overall design are completely original, but they borrow elements from the classic busses—to include, surprisingly, their electric propulsion. “Not only were electric cars pretty typical, as a matter of fact they were almost dominant [in the early 1900s],” Wenig says.

Batteriser is a $2.50 gadget that extends disposable battery life by 800 percent | Cool Future Technologies | Scoop.it

Count the number of alkaline batteries in your house. Now consider replacing those batteries eight times less often. If Batteriser delivers, it could be a game changer.


A completely new alkaline battery is rated to generate 1.5 volts, but once its output drops below 1.35 or even 1.4 volts, it effectively becomes useless to many devices. The battery’s chemical cocktail is still loaded with juice, but the circuitry in many gadgets (especially more sophisticated ones, like Bluetooth keyboards and bathroom scales) considers the battery dead. 


This is where Batteriser comes in. It’s essentially a voltage booster that sucks every last drop of useable energy from ostensibly spent batteries. So, instead of using just 20 percent of all the power hidden inside of your Duracells and Energizers, Batteriser makes effective use of the remaining 80 percent.

In a regular camera, each pixel represents the intensity of the light received from a specific point in the image, which could be near or far from the camera—meaning that the pixels provide no information about the relative distance of the object from the camera.


In contrast, each pixel in an image created by the Caltech team's NCI provides both the distance and intensity information.
