Deep Geothermal: The Untapped Renewable Energy Source

Deep Geothermal: The Untapped Renewable Energy Source | Cool Future Technologies | Scoop.it
Until now, geothermal technology has only been used on a small scale to produce power. But with major new projects now underway, deep geothermal systems may soon begin making a significant contribution to the world’s energy needs.

 

Ultimately, thanks to unusually hot rock close to the surface and existing infrastructure from oil-and-gas production, the Cooper River basin alone could produce about 10,000 megawatts of electricity — enough to replace 20 large coal-fired power plants, says geologist Doone Wyborn, Geodynamic's chief scientist. That’s just a taste of the potential that this technology, known as enhanced geothermal systems, holds for Australia and the world, according to Wyborn.

 

In the US, researchers estimate that for just $1 billion invested over 40 years — the cost of one large coal-fired power plant and a fraction of the cost of a nuclear power plant — 100 gigawatts of clean, dependable geothermal power could be developed in the United States alone. That’s the energy equivalent of more than 200 coal-fired power plants or 100 new nuclear power plants.

Some more background on geothermal energy.  Last year, the Hawaii Electric Light Company (HELCO) announced that it would invest more time and money in exploring promising geothermal sites throughout the state.  As petroleum-based fuels get more expensive and harder to extract, geothermal could provide a basic energy "cushion" for Hawaii at a reasonable cost.  Aloha, Russ

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...

Sepp Hasslberger's insight:

Yildiz' magnet motor was demonstrated at Delft University in the Netherlands and to the consternation of scientists ... it actually worked. They could not understand how. Our knowledge of magnetism and how it works seems to be either incomplete or worse, faulty.

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...

Top 5 physiological computing platforms

Top 5 physiological computing platforms | Cool Future Technologies | Scoop.it

Physical computing has the Arduino and its successors and predecessors as stepping-stones, whereas physiological computing poses a set of challenges that the DiY hardware community is tackling in novel and creative ways.


Physiological computing focuses on the use of biosignals for the development of interactive software and hardware systems capable of sensing, processing, reacting, and interfacing the digital and analog worlds.


Although they are not classified as full-fledged medical devices, each of these platforms enables us to learn and build a pretty comprehensive body of knowledge about our health status.


In light of the book "The Creative Destruction of Medicine" by Eric Topol, low-cost DIY hardware for physiological computing is just another ingredient of a digital (r)evolution bound to create better health care practices.

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...

Disabled seize life with hand of a superhero | Cool Future Technologies | Scoop.it

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.


"We have several thousand people on our site who are asking to help make hands," said Schull, a research scientist at the Rochester Institute of Technology. "What could be more rewarding than using your 3D printer to make a hand for someone?"

GoTenna enables your smart phone to communicate without the need for any central connectivity — no Wi-Fi, cell towers or satellites needed.


The gadget uses long-range radio waves — between 151-154 MHz — to send messages to other goTenna devices within its range. Depending on the surrounding terrain and elevation, the device can send messages up to 50 miles away.


But if you happen to be a city dweller with dozens of concrete and steel buildings in between you and your buddy, the range shrinks to roughly 1 mile.

Silent, tree-shaped wind turbines to debut in Paris

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.

Print Your Own Disease-Detecting Microscope for 50 Cents

Print Your Own Disease-Detecting Microscope for 50 Cents | Cool Future Technologies | Scoop.it

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. The idea is to create a crowd-sourced microscopy manual with data and ideas collected from the participants in the study.

“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.

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.

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.
