If you’re not paying attention to what’s going on in energy, you should. We’ve seen this movie before. Spoiler alert: There’s massive economic opportunity ahead. How massive? Imagine standing in 1992, knowing that Google, Akamai, Netflix, Facebook, Amazon, eBay, BuzzFeed and Uber lay ahead.

This time it’s the “enernet,” not the internet, that will transform our lives. The story is the same, though the players have changed.

Here’s the tee up. Across the country, incumbent network providers operate highly centralized networks in their respective cities. Then, scrappy local outfits start serving the market with innovative, distributed technology. These startups create competition, and a new network emerges atop the legacy network.

Research by scientists at Swansea University is helping to meet the challenge of incorporating nanoscale structures into future semiconductor devices that will create new technologies and impact on all aspects of everyday life.

Dr Alex Lord and Professor Steve Wilks from the Centre for Nanohealth led the collaborative research published in Nano Letters. The research team looked at ways to engineer electrical contact technology on minute scales with simple and effective modifications to nanowires that can be used to develop enhanced devices based on the nanomaterials. Well-defined electrical contacts are essential for any electrical circuit and electronic device because they control the flow of electricity that is fundamental to the operational capability.

Everyday materials that are being scaled down to the size of nanometres (one million times smaller than a millimetre on a standard ruler) by scientists on a global scale are seen as the future of electronic devices. The scientific and engineering advances are leading to new technologies such as energy producing clothing to power our personal gadgets and sensors to monitor our health and the surrounding environment.

HOUSTON, Jan. 18, 2017 /PRNewswire/ — Made In Space and Axiom Space today, announce an agreement to be users and providers of one another’s capabilities to manufacture products in space. Made In Space is the only company to produce 3D printed products in Space and Axiom Space is the leading developer of the world’s first privately-owned commercial space station. This collaboration signifies Made In Space’s exciting transition from research phase, to manufacturing for commercial customers.

The companies have been working out the logistical elements of in-space manufacturing, outfitting the in-space factory with equipment, utilities, power, and thermal management to answer customers’ growing demand. In parallel to the manufacturing element, the companies are working together to plan the delivery of completed products to Earth, ensuring their quality during flight and upon arrival.

  • Exploiting the usage of 2 D crystals in methanol fuel cells

ChemEurpoe — Scientists from the School of Chemical Engineering and Analytical Science, in the University of Manchester have come up with a way to utilize 2D materials in an actual operating direct methanol fuel cell. They have shown that the addition of single layer graphene by Chemical vapour deposition, on to the membrane area has significantly reduced the methanol cross over at the same time obtaining negligible resistance to protons thereby enhancing the cell performance by 50%.

Fuel cells count as interesting energy technology of the near future, as they pave the way for the production of sustainable energy using simple hydrocarbons as fuels. They work by a simple operational mechanism with the fuel oxidation on one side, and oxidant reduction on other side, which liberates electrons used for electrical energy generation. A wide variety of fuels, short chain alcohols have been used so far. Methanol remains a favourable candidate due to its high energy density, ease of handling and other operational characteristics.

Attention all seaweed farmers! US DoE and DARPA wants you.

Did you know that the amount of commercially produced seaweed almost hit the mark of 25 million metric tons last year? China and Indonesia dominate the global seaweed-to-food market, and now the Department of Energy has been casting a hungry eye on the potential for the US to get in on the action, with a particular focus on converting seaweed to biofuel and other high value products.

Of course, there is a problem. Growing seaweed — aka macroalgae — for food is one thing. The algae-to-energy cycle is quite another thing entirely. That’s why the Energy Department has called upon its cutting edge funding division, ARPA-E, to put out a call for the super macroalgae farmer of the future.

Within the next fifty years, scientists at BAE Systems believe that battlefield commanders could deploy a new type of directed energy laser and lens system, called a Laser Developed Atmospheric Lens which is capable of enhancing commanders’ ability to observe adversaries’ activities over much greater distances than existing sensors.

At the same time, the lens could be used as a form of ‘deflector shield’ to protect friendly aircraft, ships, land vehicles and troops from incoming attacks by high power laser weapons that could also become a reality in the same time period.

The Laser Developed Atmospheric Lens (LDAL) concept, developed by technologists at the Company’s military aircraft facility in Warton, Lancashire, has been evaluated by the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory and specialist optical sensors company LumOptica and is based on known science. It works by simulating naturally occurring phenomena and temporarily — and reversibly — changes the Earth’s atmosphere into lens-like structures to magnify or change the path of electromagnetic waves such as light and radio signals.

In Brief

  • Scientists are a little bit closer to unlocking the mystery of how the rules of the quantum realm translate to the rules of the classical physics of the observable world.
  • Experts predict that the materials used in this research, topological insulators, will play a key role in furthering this development.

It’s no surprise that quantum physics can be disorienting to the casual observer; after all, it does follow its own set of rules quite different from those of classical physics which rule over our everyday experience. In the quantum realm, things can and cannot be at the same time (to a certain extent) or are continually moving without spending energy. These don’t apply to the physics of macro-level matter.

These two realms are related, in so far as they occur in the same physical space. This relationship is what N. Peter Armitage, an associate professor of physics at Johns Hopkins University, wanted to figure out in a study published in the journal Science. “We found a particular material that is straddling these two regimes,” Armitage said.

This publication suggests that wax could be carried on vehicles and used to create hydrogen gas in situ, the waste carbon being used to make more wax via syngas production and the Fischer-Tropsch process, where carbon monoxide and hydrogen is converted into hydrocarbons as a potential source of petro-chemicals that does not involve releasing fossil carbon into the atmosphere. While this publication is still a long way from a working industrial-scale process, it offers a very hopeful potential avenue for less-polluting technology.

Philip recently attended an event for other Oxford University chemistry alumni, and one of the speakers drew attention to a recent publication from, among others, Oxford chemists, regarding the production of hydrogen from paraffin waxes by microwave degradation using a ruthenium catalyst.

Hydrogen has often been suggested as an environmentally-friendly replacement energy source for fossil fuels in transport vehicles and other applications requiring high energy density. (Note that hydrogen is not a “fuel”, as it must be made using energy from other sources, which can be environmentally-friendly or not.) However, there are significant problems with this, notably involving the safe storage of a highly-inflammable and explosive gas which is much lighter than air.
