A low-cost water splitter that runs on an ordinary AAA battery

Could allow for true zero-emissions fuel-cell vehicles and save hydrogen producers billions of dollars in electricity costs
August 22, 2014

Stanford scientists have developed a low-cost device that uses an ordinary AAA battery to split water into oxygen and hydrogen gas. Gas bubbles are produced by electrodes made of inexpensive nickel and iron.

A cheap, emissions-free device that uses a 1.5-volt AAA battery to split water into hydrogen and oxygen by electrolysis has been developed by scientists at Stanford University.

Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive, abundant nickel and iron.

“This is the first time anyone has used non-precious metal catalysts to split water at a voltage… read more

Is the world’s only commercial quantum computer really a quantum device, or a just regular computer in disguise? Controversy has long swirled around the computer produced by D-Wave, a company based near Vancouver, Canada.

Now a paper published on the arXiv preprint server takes a step forward in showing that it really does operate on a quantum level, Nature News Blog reports.

Berkeley Lab scientists record first inside look at carbon-capture molecular structure

November 26, 2013

Mg-MOF-74 is an open metal site MOF whose porous crystalline structure could enable it to serve as a storage vessel for capturing and containing the carbon dioxide emitted from coal-burning power plants. (National Academy of Sciences)

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) have recorded the first electronic structure observations of the adsorption of carbon dioxide inside a metal-organic framework (MOF).

The “Mg-MOF-74″ MOF’s porous crystalline structure could enable it to serve as a storage vessel for capturing and containing the carbon dioxide emitted from coal-burning power plants.

MOFs are molecular systems consisting of a metal oxide center surrounded by organic… read more

IBM developing 150-petaflops supercomputers for national labs

New "data-centric" architecture deals with Big Data by embedding compute power everywhere data resides

One trillion connected objects and devices on the planet will be generating data by 2015 --- currently 2.5 gigabytes per day (credit: IBM)

IBM today (Nov. 14) announced that the U.S. Department of Energy has awarded IBM contracts valued at $325 million to develop and deliver “the world’s most advanced ‘data-centric’ supercomputing systems” at Lawrence Livermore and Oak Ridge National Laboratories to advance innovation and discovery in science, engineering and national security.”

The world is generating more than 2.5 billion gigabytes of “big data” every day, according to IBM’s 2013 annual report, requiring… read more

A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor.

The researchers’ new imaging technique, based on the detection of calcium ions in neurons, could help them map the brain circuits that perform such functions.

It could also provide new insights into the… read more

How to identify and predict human activities from video

A video shows a woman carrying a box into a building.  Later, it shows her leaving the building without it. What was she doing?

Carnegie Mellon University’s (CMU) Mind’s Eye program is creating intelligent software that will recognize human activities in video and predict what might happen next. It will also flag unusual events and deduce actions that may be occurring off-camera.

Automating the time-consuming job of… read more

Teaching household robots to manipulate objects more efficiently

New algorithms could help household robots work around their physical shortcomings

At this year’s IEEE International Conference on Robotics and Automation, students in the Learning and Intelligent Systems Group at MIT’s Computer Science and Artificial Intelligence Laboratory will present a pair of papers showing how household robots could use a little lateral thinking to compensate for their physical shortcomings.

Many commercial robotic arms perform what roboticists call “pick and place” tasks: The arm picks… read more

Cloning quantum information from the past

In the film "Looper," time travel is invented by the year 2074 and, though immediately outlawed, is used by criminal organizations to send those they want killed into the past where they are killed by "loopers." (Credit: TriStar Pictures)

It is theoretically possible for time travelers to copy quantum data from the past, according to three scientists in a recent paper in Physical Review Letters.

It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the Grandfather paradox*.  He solved the paradox originally using a slight change to quantum theory,… read more

First Earth-size planet in ‘habitable zone’ discovered

Astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone” — the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun.

Planets have previously been found in the habitable zone, but they are all… read more

A cost-effective nanotube-based catalyst for producing hydrogen fuel

Rutgers researchers have used carbon nanotubes as a catalyst for splitting water into hydrogen and oxygen, which could replace expensive platinum for making clean-burning hydrogen fuel — which could one day replace expensive, environmentally harmful fossil fuels.

The Rutgers technology is also far more efficient than other low-cost catalysts investigated to date for electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen,… read more

How to become the engineers of our own evolution

March 20, 2012

singularityfringe

Adherents of “transhumanism” — a movement that seeks to transform Homo sapiens through tools like gene manipulation, “smart drugs” and nanomedicine — hail developments such as prototype bionic eyes and printed tracheas as evidence that we are becoming the engineers of our own evolution.

Transhumanists say we are morally obligated to help the human race transcend its biological limits; those who disagree are sometimes called Bio-Luddites. “The human quest… read more

Printable houses are coming

April 11, 2012

Italian inventor Enrico Dini, chairman of Monolite UK Ltd, has developed a huge three-dimensional printer called D-Shape that can print entire buildings out of sand and an inorganic binder. The printer works by spraying a thin layer of sand followed by a layer of magnesium-based binder from hundreds of nozzles on its underside. The glue turns the sand to solid stone, which is built up layer-by-layer from the bottom up to form anything from a sculpture to a sandstone building. (Credit: Monolite)

The first “printed homes” will be coming soon, says World Future Society blogger Thomas Frey.

One construction technology that has great potential for low-cost, customized buildings is “contour crafting — a form of 3D printing that uses robotic arms and nozzles to squeeze out layers of concrete or other materials, moving back and forth over a set path to fabricate a large component.

Structures would be quicker to make,… read more
