Artificial Photosynthesis Yields Valuable Chemicals. Tiny semiconductors and bacteria have been combined to create a system that uses sunlight to turn carbon dioxide into valuable chemicals.

Artificial Photosynthesis Yields Valuable Chemicals

Photosynthesis forms the basis of most life on Earth. However, it cannot draw carbon dioxide out of the atmosphere fast enough to match the rate at which we are releasing what was stored over millions of years. This has led to a quest to produce an artificial and more efficient version – ideally one that would turn the carbon into something we can easily use. Recently, there has been a lot of work based around the idea of combining bacteria with manufactured materials.

The Lawrence Berkeley National Laboratory has announced what team leader Professor Peidong Yang calls “a revolutionary leap forward” in this area. "Our system has the potential to fundamentally change the chemical and oil industry in that we can produce chemicals and fuels in a totally renewable way, rather than extracting them from deep below the ground,” says Yang. Audi have successfully made diesel fuel from carbon dioxide and water. German car manufacturer Audi has reportedly invented a carbon-neutral diesel fuel, made solely from water, carbon dioxide and renewable energy sources.

And the crystal clear 'e-diesel' is already being used to power the Audi A8 owned by the country’s Federal Minister of Education and Research, Johanna Wanka. The creation of the fuel is a huge step forward for sustainable transport, but the fact that it’s being backed by an automotive giant is even more exciting. Audi has now set up a pilot plant in Dresden, Germany, operated by clean tech company Sunfire, which will pump out 160 litres of the synthetic diesel every day in the coming months. Their base product, which they’re calling 'blue crude' is created using a three-step process. The first step involves harvesting renewable energy from sources such as wind, solar and hydropower. This hydrogen is then mixed with carbon monoxide (CO), which is created from carbon dioxide (CO2) that’s been harvested from the atmosphere.

Japan space scientists make wireless energy breakthrough. Japanese scientists have succeeded in transmitting energy wirelessly, in a key step that could one day make solar power generation in space a possibility, an official said Thursday.

'Miracle' tech turns water into fuel

In February 2013, a group of heavy-hitting companies led by Samsung held a glitzy evening event in Barcelona -- complete with freshly shucked oysters and made-to-order crepes -- to mark the debut of the Tizen mobile operating system, co-developed by Samsung and Intel. Telecom executives from Japan's NTT Docomo and France's Orange were on hand to show their support, committing to high-end smartphones that would rival Apple's iOS and Google's Android mobile operating systems. Kiyohito Nagata, managing director of strategic marketing for NTT DoCoMo and then-chairman of the Tizen Association, hailed the event as "the basement of the future success of the Tizen OS and ecosystem. " Nearly two years later, the glamor -- along with industry interest -- has faded. Evolution-of-renewable-energy-redlogo-compressed-55ad432075034ee5c875d99c8957cf38.jpg (1800×13848)

At the time of writing, each of these innovations is currently seeking funding. The solar energy industry is still in the process of exploring how to make photovoltaic panels more efficient and less intrusive, and researchers at Stanford have already pushed forward with peel-and-stick solar panels. Glucose-based battery has 10 times energy of lithium: researchers. Brazilian sugarcane Humans and batteries--and indeed most other things in the natural world, operate on largely similar principals.

Glucose-based battery has 10 times energy of lithium: researchers

Energy is generated somehow, stored, and expended for work. It's only the details that separate these processes, but the gap might shrink with the advent of biobatteries. As ExtremeTech reports, researchers at Virginia Tech have developed a working sugar-powered fuel cell with energy density greater than that of current lithium-ion batteries. MIT researchers find messy batteries might be better. As modern technology demands more and more power, lithium-ion batteries have been getting increasingly dense.

MIT researchers find messy batteries might be better

There hasn’t been a true breakthrough in battery technology recently, so scientists have been working on ways to fit more components inside the same space. That means very precise work to keep everything neat and tidy. Now a team of researchers from MIT is pointing out some disorder could be a good thing in lithium-ion batteries.

One of the issues engineers have had to contend with when layering battery components was that the materials might not hold up and could blend together.

Food versus Fuel: Native Plants Make Better Ethanol. A mix of perennial grasses and herbs might offer the best chance for the U.S. to produce a sustainable biofuel, according to the results of a new study. But making that dream a reality could harm local environments and would require developing new technology to harvest, process and convert such plant material into biofuels such as ethanol.

Biofuels have become controversial for their impact on food production. Breakthrough iron-based superconductors set new performance records. (Phys.org)—The road to a sustainably powered future may be paved with superconductors. When chilled to frigid temperatures hundreds of degrees Celsius below zero, these remarkable materials are singularly capable of perfectly conducting electric current. To meet growing global energy demands, the entire energy infrastructure would benefit tremendously from incorporating new electricity generation, storage, and delivery technologies that use superconducting wires. But strict limits on temperature, high manufacturing costs, and the dampening effects of high-magnetic fields currently impede widespread adoption. Now, a collaboration led by scientists at the U.S. Princeton’s nanomesh nearly triples solar cell efficiency. There is huge potential in solar power. Scientists design first all-carbon solar cell.
