Making Salt Water Drinkable Just Got 99 Percent Easier

Making Salt Water Drinkable Just Got 99 Percent Easier | Cool Future Technologies | Scoop.it
Access to steady supplies of clean water is getting more and more difficult in the developing world, especially as demand skyrockets.

 

Lockheed Martin's Perforene, on the other hand, is made from single atom-thick sheets of graphene. Because the sheets are so thin, water flows through them far more easily than through a conventional TFC.

 

Filters made through the Perforene process would incorporate filtering holes just 100 nm in diameter—large enough to let water molecules through but small enough to capture dissolved salts. It looks a bit like chicken wire when viewed under a microscope

Sepp Hasslberger's insight:

This looks like a quantum leap on desalinization of sea water - making availability of drinking water from the sea a very real possibility, without huge and power hungry reverse osmosis desalinization plants.

Yes, it would seem that those kinds of filters could satisfy our demand for water with great efficiency. Let's hope this works out.

Only 3% of the water in the planet is freshwater meaning non salty water. With this technology we will fully take advantage of the Earth's water. We could even rename our planet and call it "Water"
timallard's comment, June 24, 2013 3:08 PM
My work is a miniaturized system for home-farm-ranch that copies larger sewage treatment plants yet uses algae to clean the water not floccing chemicals. Bioreactors are used for this and most made for large batch processing so my design is a cube 1/2m on a side full of glass plates that light the entire volume well, easy to aerate and will include harvesting to a slurry that's processed for biodiesel, a high-volume supply. Then the de-watered cakes are quality fertilizer so you get pure water, biodiesel and fertilizer from this system intended to be sold in home-farm supply stores with parts and service people.

With this a small dairy operation can produce their fuel from the washdown, getting the water back as well and fertilzer so it's clear the benefits possible from bringing this to the market.

Making Hardware Is a Total Pain. But Not in This Factory | a WIRED article

Making Hardware Is a Total Pain. But Not in This Factory | a WIRED article | Cool Future Technologies | Scoop.it

Chris Church wanted a factory where you could simply request the resources you needed through the Web. So he started one.


What Church really wanted was for manufacturing to work more like cloud computing, where you can simply request the resources you need through the web. He wanted to be able to upload his designs to a manufacturer, get a quote automatically, and, when the time comes, order a batch of prototypes with a push of a button, instead of having to spend hours and hours going over spreadsheets with sales reps.


That didn’t exist, so, along with electrical engineer Parker Dillmann, he started a factory called MacroFab that lets hardware designers do just that.

Mexican students invent self sustaining electric motorbike - YouTube (2min)

there are 2 young Mexican inventors, Victor Garcia, age 17 and Raul Grajales, who has built and shown a selfsustaining electric motorbike.

It is started by a conventional 12 Volts Lead Acid battery and if the back wheel goes faster than 2000 RPM the whole bike gets selfsufficient and propels itself via some kind of recharging process.


They also use 2 big 1.5 Farad Supercapacitors for the recharge storage and probably these supercaps also recharge then the battery.

Here is the text Reuters has published about this invention:

Mexican students invent eco-friendly motorbike

What if you could harvest the energy of a moving vehicle to continue to power it ? 

That is the question asked by students of this technical high 
school college in Oaxaca, Mexico, one year ago. 

It resulted in this prototype motorcycle called R-Walker created by 17-year-old Victor Garcia.

VICTOR GARCIA, SAYING:

“The project is a prototype that generates its own energy as it goes along: As it goes faster and covers longer distances, 
it generates more energy. In that way, you don’t have to charge the battery every 6-8 hours.”

Garcia calls the process “auto-sustainability.”

It’s based on the principle of converting energy through speed and distance travelled; the engine becomes self-sustaining, generating more than 2,000 revolutions per minute.

A battery is used to spark ignition, and afterwards without using any combustion the vehicle can carry up to 110 kilograms and travel at more than 60 kilometers per hour.

Co-designer Raul Grajales said R-Walker could bring huge savings for motorcycle users, as well as the environment.

RAUL GRAJALES, SAYING:

“With this, we have reduced the use of 200 batteries a day and seventy percent of pollution, because it does not contaminate and has zero emissions and we use one battery every 5-10 years.”

They built the eco-friendly motorbike from recycled materials, bringing its final price tag to around $200 – a comparatively small sum when considering its potential benefits.

The Power of the Vortex: An Interview with David Suriol of Vortex Bladeless Piezoelectric Turbines

The Power of the Vortex: An Interview with David Suriol of Vortex Bladeless Piezoelectric Turbines | Cool Future Technologies | Scoop.it

Our wind generator does not have any moving parts in contact, which eliminates the need for lubrication and reduces wear and tear.


Thanks to a self-tuning magnetic coupling system, Vortex can operate in a wider range of wind speeds.


Our technology has two main advantages over the traditional wind turbine: we are cheaper, and more environmentally friendly (noise absence and no oil required for maintenance).


To demonstrate the feasibility of the technology, we have tested dozens of prototypes in wind tunnel, and we are currently doing field tests of complete small-scale equipment.


The device consists of a rigid vertical cylinder, anchored to the ground, and including piezoelectric materials. Electric power is generated by the deformation suffered suffered by these materials as a result of oscillations due to resonance with the wind.


(http://www.techamster.com/vortex-generator-bladeless-turbine/)

Sepp Hasslberger's insight:

This is significant as it's a first step away from the "windmill" type of generators with rotating blades. Vortex-induced oscillation is transformed to electricity by piezoelectric technology. 

It is still years away from commercialisation, but I believe it could be a valid improvement over what we have today.

Permanent magnet motors coming to market - Plans for 2015 production of the Yildiz magnet Motor

Permanent magnet motors coming to market - Plans for 2015 production of the Yildiz magnet Motor | Cool Future Technologies | Scoop.it

Over the last few years we have been improving the magnet motor.


We are now in the process of perfecting the prototypes of the motor, to be able to start production of a limited number of motors.


The production of magnetic rotators for the power range of up to 5 kVA will commence on January 1st, 2015.


This first edition of the motor will be sold customers willing to participate in beta testing...

Audi Has Made Diesel From Water And Carbon Dioxide

Audi Has Made Diesel From Water And Carbon Dioxide | Cool Future Technologies | Scoop.it

German car manufacturer Audi has declared that they have been able to create an "e-diesel," or diesel containing ethanol, by using renewable energy to produce a liquid fuel from nothing more than water and carbon dioxide.


After a commissioning phase of just four months, the plant in Dresden operated by clean tech company Sunfire has managed to produce its first batch of what they’re calling “blue crude.” 

The liquid produced is composed of long-chain hydrocarbon compounds, similar to fossil fuels, but free from sulfur and aromatics and therefore burns soot-free.


The first step in the process involves harnessing renewable energy through solar, wind or hydropower. This energy is then used to heat water to temperatures in excess of 800oC (1472oF). The steam is then broken down into oxygen and hydrogen through high temperature electrolysis.

Sepp Hasslberger's insight:

It's been done before, even in a much simpler way. In the 1920's Viktor Schauberger experimented with water vortex flow in closed containers with carbon dioxide added and he obtained a flammable liquid. And no, it doesn't necessarily take a lot of energy to do it. Water vortex and carbon dioxide atmosphere under pressure will do it after several hours of rotation. The vortex folds the carbon from carbon dioxide right into the water, making hydrocarbons which are fuel...

This Water Faucet Saves Water By Creating Beautiful Spirals | Cool Future Technologies | Scoop.it

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...

The proliferation of 3D printers has had an unexpected benefit: The devices, it turns out, are perfect for creating cheap prosthetics.


The fingers are closed by flexing the wrist, which pulls on cable "tendons". Move the wrist again, and the hand opens. The hands are printed in pieces, which are assembled by volunteers, or by parents and children themselves.


More than 50 groups, such as Boy Scout and Girl Scout troops and schools like Convent of the Sacred Heart in Manhattan, have created hands for about 500 children.

Field Testing Steorn’s ‘Never Die’ Orbo Power Cube Battery in Dublin Pub Starting Friday [New Pictures and video] | Cool Future Technologies | Scoop.it

We don’t know much about the Orbo power cube, but Shaun McCarthy has mentioned that Steorn is developing a ‘never-die’ battery using its Orbo technology.

“The battery is very unique — You don’t put any energy in, it’s what they call a closed loop. Literally the battery is self-powered. It’s a ‘never die’ battery. It’ll drain itself, but it will recharge itself in two seconds.”


To many, Steorn has become an object of ridicule over the years, and so to display a potentially revolutionary technology for the first time in a pub doesn’t sound like the best way to try and salvage your reputation — but in many ways this is the Steorn way, tongue-in-cheek and irreverent.

A bioengineering assistant professor at Stanford University has created a functional paper microscope for only $0.50.


Foldscope is a completely functional Origami-like microscope that costs less than $0.50 to produce. No bigger than a bookmark but with the ability to magnify samples up to 2,000 times their original size, the device holds within its cardstock frame the same advanced microscopic technology of most research microscopes without the high costs and complex assembly.


“I wanted to make the best possible disease-detection instrument that we could almost distribute for free,” Prakash told Scope. “What came out of this project is what we call use-and-throw microscopy.” 


The Foldscope weighs less than two nickels, can be built in minutes, and forgoes written instructions for simple, color-coded perforations. It requires no external power, is durable enough to be submerged in water or dropped from a three-story building without damage, and can be incinerated after use for safe disposal of infected slides.


Prakash and his team are currently offering 10,000 Foldscopes to citizen scientists who apply with the most inspiring and creative potential applications of the paper telescope.

“Ere many generations pass; our machinery will be driven by a power obtainable at any point in the universe.” – Nikola Tesla


A Reactionless AC Synchronous Generator has been invented by Paramahamsa Tewari, electrical engineer and former Executive Director of Nuclear Power Corporation of India. His background includes engineering project management for construction of nuclear power stations. The efficiency of models he has built, which have also been independently built and tested, is as high as 250%.


"I believe, as do the engineers in India, that this is the biggest breakthrough in rotating electrical machine design since Faraday’s invention of the electrical motor in 1832. The elimination of back torque allows all the energy generated to pass through the machine. Power output is determined by the strength of the excitation magnets and the synchronous reactance (resistance at 50/60 Hz) of the stator windings."

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."

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.
