Kool, the sooner we can stop worrying about our effects on the carbon cycle so greatly the better. We can grow algae in the oceans.


Hydrogen is a very clean fuel that is increasingly being used as vehicle fuel and to generate electricity. The problem is how to produce it efficiently without generating significant carbon emissions and at a competitive cost. A team of researchers at Imperial College is currently looking at the problem and think they know how to do it.

Stanford and UC Berkeley researchers have a solution to the problem of storing energy from wind, water and solar power overnight (or in inclement weather): store it underground. The system could result in a reliable, affordable national grid, replacing fossil fuel, they believe.”

This new touchscreen material could see the end of daily smartphone charging

Posted by in categories: electronics, energy, materials, mobile phones

Scientists in the UK have invented a new type of touchscreen material that requires very little power to illuminate, offering up a cheap alternative to today’s smartphone and tablet screens, with vivid colours and high visibility in direct sunlight.

The team is already in talks with some of the world’s largest consumer electronics corporations to see if their new material can replace current LCD touchscreens in the next couple of years, which could spell the end for daily smartphone charging. “We can create an entire new market,” one of the researchers, Peiman Hosseini, told The Telegraph. “You have to charge smartwatches every night, which is slowing adoption. But if you had a smartwatch or smart glass that didn’t need much power, you could recharge it just once a week.”

Developed by Bodie Technologies, a University of Oxford spin-off company, the new display is reportedly made from a type of phase-change material called germanium-antimony-tellurium, or GST. The researchers are being understandably cagey about exactly how it’s made as they shop the technology around, but it’s based on a paper they published last year describing how a rigid or flexible display can be formed from microscopic ‘stacks’ of GST and electrode layers.

New ‘self-healing’ gel makes electronics more flexible

Posted by in categories: electronics, energy, materials

Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices.

Although technology is moving toward lighter, flexible, foldable and rollable electronics, the existing circuits that power them are not built to flex freely and repeatedly self-repair cracks or breaks that can happen from normal wear and tear.

Until now, self-healing materials have relied on application of external stimuli such as light or heat to activate repair. The UT Austin “supergel” material has high conductivity (the degree to which a material conducts electricity) and strong mechanical and electrical self-healing properties.

This new battery charges 10 times faster than the one in your smartphone

Posted by in categories: energy, mobile phones

Chinese technology company Huawei has announced that its latest prototype battery fills up with power 10 times quicker than the ones in current smartphones. Huawei has been showing off the technology at the 56th Battery Symposium in Japan this week, where a 3,000mAh pack reached a 48 percent charge in just 5 minutes.

The lithium-ion batteries inside smartphones, tablets, and other similar gadgets have two main sections: an anode and a cathode. Electrons move from one section to the other while our devices are in use, and then back in the opposite direction as they are recharged.

‘Power Over Wi-Fi’ named one of the year’s game-changing technologies

Posted by in categories: electronics, energy, internet

University of Washington engineers have developed a novel technology that uses a Wi-Fi router—a source of ubiquitous but untapped energy in indoor environments—to power devices.

The Power Over Wi-Fi (PoWiFi) system is one of the most innovative and game-changing technologies of the year, according to Popular Science, which included it in the magazine’s annual “Best of What’s New” awards announced Wednesday.

The technology attracted attention earlier this year when researchers published an online paper showing how they harvested energy from Wi-Fi signals to power a simple temperature sensor, a low-resolution grayscale camera and a charger for a Jawbone activity tracking bracelet.

Scientists develop ‘nanopores’ that inexpensively filter the salt out of seawater

Posted by in categories: energy, engineering, materials

There’s filtration and then there’s filtration. Engineers in the US have been working on the latter, coming up with a new markedly more energy-efficient way of taking the salt out of seawater, which could deliver huge advantages in terms of providing people with access to drinking water and help combat problems like drought.

The researchers have developed a material that allows high volumes of water to pass through extremely tiny holes called ‘nanopores’ while blocking salt and other contaminants. The material they’re using – a nanometre-thick sheet of molybdenum disulphide (MoS2) riddled with these nanopore holes – is the most efficient of a number of thin-film membranes that the engineers modelled, filtering up to 70 percent more water than graphene.

“Even though we have a lot of water on this planet, there is very little that is drinkable,” said Narayana Aluru, a professor of mechanical science and engineering at the University of Illinois and leader of the study. “If we could find a low-cost, efficient way to purify sea water, we would be making good strides in solving the water crisis.”
