Researchers develop first high-gravity, one-pot process for producing cellulosic ethanol

Biofuels can help mitigate climate change and provide us with a sustainable source of transportation energy if yields and production costs are economically competitive. A major step towards achieving this goal has been achieved by researchers with the U.S. Department of Energy (DOE)'s Joint BioEnergy Institute (JBEI). New 'nano-reactor' biomaterial catalyzes hydrogen biofuel. BLOOMINGTON, Ind., Jan. 5 (UPI) -- By hiding a modified enzyme inside a virus, researchers have created a new biomaterial capable of efficiently catalyzing the production of hydrogen.

The so-called "nano-reactor" could lead to more efficient and profitable biofuel production processes. Researchers just made batteries from mushrooms... and they're surprisingly good. Researchers in the US have created a new type of lithium-ion battery that uses portabella mushrooms - yes, you read that right - instead of the graphite that currently forms the batteries inside our mobile phones.

And while it sounds like the type of idea you might hear at a high school science fair, evidence suggests that these new batteries might actually last longer than traditional batteries, and could give our phones better battery life as they age. And that's not all - the mushroom batteries are also incredibly cheap, easy to make, and, best of all, they're pretty much biodegradable. Which will make a big difference to the environment as our demand for batteries skyrockets with the 6 million electric vehicles predicted to be built by 2020. Now, we know what you're thinking - how the hell do you make a battery out of a mushroom? Scientists make huge hydrogen energy discovery. It’s one of the holy grails of the energy industry: a cost-effective way to generate hydrogen, and a team of researchers thinks they may have just found it.

Scientists make huge hydrogen energy discovery

Scientists at the University of Wisconsin believe the have found a cheap and efficient way to produce hydrogen without having to use noble gases as a catalyst, and they were able to do it by combining phosphorous and sulfur, two common elements, as well as cobalt, a metal that is much cheaper than even the cheapest noble metal, according to a UPI report. It’s an important discovery because scientists hope to fuel the future world with an eco-friendly source, and hydrogen could be that source: it can be burned for heat or used in fuel cells, and they don’t give off bad emissions like fossil fuels when burned: hydrogen’s byproduct is water. 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.

Sugar-powered biobattery has 10 times the energy storage of lithium: Your smartphone might soon run on enzymes

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. 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.

New "Solar Fuel Cell" Is More Efficient By A Factor Of 10

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. As Daniel Nocera gazed down on one of his experiments in what has come to be known as the "holy grail" of energy research, his response was to shrug:

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).

Plant-e Modular

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.

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.

Audi have successfully made diesel fuel from carbon dioxide and water

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. Resource-poor Japan has to import huge amounts of fossil fuel. 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.

Teens Create A Way To Use Urine As Fuel. 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.

“And then someone calls you on your satellite phone and asks you, ‘How long is it going to take you to climb to the top of the mountain?’ You just don’t know.” Hurricane and other scientists at the Lawrence Livermore National Laboratory, home of the multibillion-dollar National Ignition Facility, took pains to calibrate their claims of success. This was not fusion “ignition,” the NIF’s ultimate ambition. The experiment overall requires much more energy on the front end — all those laser shots —than comes out the back end. Only about 1 percent of the energy from the laser actually winds up in the fuel, according to Debra Callahan, a co-author of the Nature paper. 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. However, for high power usage the devices must be large and in direct contact with the sun at all times, meaning they need to track its position in the sky using sensors and equipment that are expensive and susceptible to bad weather.

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. Sugar, or more accurately glucose, is an excellent source of energy in biological beings, as it's energy-dense and easy for a plant or animal to process. MIT researchers find messy batteries might be better. Researchers Bioengineer Bacteria That Poops Out Gasoline.
