Angela Belcher: Using nature to grow batteries. Sugar-powered biobattery has 10 times the energy storage of lithium: Your smartphone might soon run on enzymes. As you probably know, from sucking down cans of Coke and masticating on candy, sugar — glucose, fructose, sucrose, dextrose — is an excellent source of energy.
Biologically speaking, sugar molecules are energy-dense, easy to transport, and cheap to digest. There is a reason why almost every living cell on Earth generates its energy (ATP) from glucose. Now, researchers at Virginia Tech have successfully created a sugar-powered fuel cell that has an energy storage density of 596 amp-hours per kilo — or “one order of magnitude” higher than lithium-ion batteries. A fully transparent solar cell that could make every window and screen a power source. New "Solar Fuel Cell" Is More Efficient By A Factor Of 10. Clean Power Published on July 22nd, 2015 | by Tina Casey July 22nd, 2015 by Tina Casey Providing a new ray of hope for hydrogen fuel cell fans, researchers at Eindhoven University of Technology have developed a more efficient way to produce the fuel needed to keep fuel cells going — namely, hydrogen.
We’ve been giving hydrogen the stinkeye because it is sourced primarily from fossil natural gas, but the Eindhoven solution works on solar energy and water, and gallium phosphide aka GaP. The artificial leaf that could power the world. Plant-e Modular. The modular system is the first product that Plant-e introduced to the market (launched in 2014).
One system consists of 100 square meter modules equipped with our technology and plants. Plant-e's modular system is suitable for small to medium scale applications. It can be applied in sizes of (multiples) 100m2 to be used for LED-lighting, power a WiFi-spot or function as a green roof while generating electricity for the building underneath. In the last case the system doesn’t only generate electricity, but adds other advantages such as insulation, water storage and increase of biodiversity.
The first two systems worldwide are installed on the Hembrug Grounds in Zaandam, and on the Food Innovation Strip connecting the municipalities of Ede and Wageningen (both in The Netherlands). 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.
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. 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.
Researchers used microwaves to deliver 1.8 kilowatts of power—enough to run an electric kettle—through the air with pinpoint accuracy to a receiver 55 metres (170 feet) away. While the distance was not huge, the technology could pave the way for mankind to eventually tap the vast amount of solar energy available in space and use it here on Earth, a spokesman for The Japan Aerospace Exploration Agency (JAXA) said. "This was the first time anyone has managed to send a high output of nearly two kilowatts of electric power via microwaves to a small target, using a delicate directivity control device," he said. JAXA has been working on devising Space Solar Power Systems for years, the spokesman said. Australia Uses the Motion of the Ocean to Generate Zero-Emission Electricity and Desalinate Water Simultaneously. 'Miracle' tech turns water into fuel. The Korean electronics giant is shifting gears again with its troubled mobile operating system, now aiming for affordability as a key characteristic of Tizen smartphones.
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)

Fusion energy milestone reported by California scientists. “You kind of picture yourself climbing halfway up a mountain, but the top of the mountain is hidden in clouds,” Omar Hurricane, the lead author of the Nature paper, said in a teleconference with journalists.
Giant glass orb could replace the solar panel. This is part of a series of articles that looks at entrepreneurs hoping to get their ideas off the ground through crowdfunding.
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.
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.
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. Lithium ions are less able to move through such muddled layers of cathode. However, the MIT team found something remarkable when working with a combination of lithium, chromium, and molybdenum for the cathode.
The battery with the disordered cathode was able to maintain an energy density of 660 watt-hours per kilogram. Researchers Bioengineer Bacteria That Poops Out Gasoline. Chemist Hopes 'Artificial Leaf' Can Power Civilization Using Photosynthesis. Imagine an artificial leaf that mimics photosynthesis, which lets plants harness energy from the sun. But this leaf would have the ability to power your homes and cars with clean energy using only sunlight and water. This is not some far-off idea of the future. It's reality, and the subject of a jury-prize-winning film in the GE Focus Forward Film Competition . Jared P. Scott and Kelly Nyks ' short film, " The Artificial Leaf ," showcases chemist Daniel Nocera , the inventor of the artificial leaf, a device that he says can power the world.
