  • Solar fuels: how planes and cars could be powered by the sun

    Solar energy is the world’s most plentiful and ubiquitous energy source, and researchers around the world are pursuing ways to convert sunlight into a useful form. Most people are aware of solar photovoltaics that generate electricity and solar panels that produce hot water. But there is another thrust of solar research: turning sunlight into liquid fuels. Research in solar-derived liquid ...

  • Q&A: A look at solar plane attempting round-the-world trip

    Two Swiss pioneers are attempting to fly around the world in a solar-powered airplane without a drop of fossil fuel. Here's a look at the plane and the pioneers behind it: HOW IS THE PLANE FLYING ONLY ON SOLAR POWER? Described by its creators as "an airborne laboratory," the single-seat Solar Impulse 2 has 17,248 ultra-efficient solar cells that transfer solar energy to four ...

  • Embedding nuclear physics rules and fuel chemistry limits in control algorithms for a fuel-efficient nuclear reactor

    In a nuclear reactor, the energy which is stored in the fuel is proportional to the amount of fissile material. The consumption of that amount, after a set burn-up, should and must result in delivering a set energy, barring leakages (losses). The loss of energy due to an inefficient control algorithm, after a set burn-up, is a problem that no one has yet addressed. Nuclear fuel chemists and ...

  • Ratio control with logarithmic logics in a new P&P control algorithm for a true fuel-efficient reactor

    The concept of expending minimum control energy while stabilising or manoeuvring reactor power for a nuclear reactor is the key for a fuel-efficient reactor control. This concept results from treating the reactor close to its natural characteristics by a new Power and Period (P&P) control scheme. This is proven by spending only the required rate of reactivity (not more) to govern the power by ...

  • Making environmentally friendly fuel from wood chips - Case Study

    The RUF briquetting press earns the Ortinger company additional profits During the production of round bars or rods for flags, skewers and many more products made from wooden planks, lots of wood chips are accumulated. Instead of disposing of them as waste, the wood processor Ortinger presses them into briquettes, which they then sell as fuel. This way they can economically support ...

  • Raising energy efficiency in a new materials economy - Part II

    There is a vast worldwide potential for cutting carbon dioxide (CO2) emissions by reducing the use of materials. This begins with the major metals--steel, aluminum, and copper--where recycling requires only a fraction of the energy needed to produce these metals from virgin ore, and with the recycling and composting of most household garbage. It continues with designing cars, appliances, and ...

  • New life for the artificial leaf?

    Research in laboratories around the world is moving the promise of artificial photosynthesis closer to reality Sandwiched between rows of bottled chemicals and racks of drying glassware on the third floor of Harvard University’s Mallinckrodt laboratory, four thumbnail-size bits of pinstriped silicon hang from a thin ...

  • What rural Alaska can teach the world about renewable energy

    I flew into Unalakleet, Alaska, on a late fall day. With about 700 people, Unalakleet is large by rural Alaska standards and serves as a regional hub. The village is located on a sandy spit of land where a clear river meets the turbid water of the Bering Sea. Out the plane window the sun shone bright, glittering off the wind-tossed whitecaps of the sea. To the east, the rolling Nulato Hills, clad ...

  • Swiss Sustainable Energy Solutions are Top

    Four years ago Allinghi, the high-tech racing yacht designed by land-locked Swiss engineers challenged established sea-faring nations off New Zealand and won the prestigious America's Cup. About the same time the Swiss pioneer Bertrand Piccard became the first to surround the globe in a hot air balloon. A Swiss crew will soon be the first to reach New York City after crossing the Atlantic with ...

  • Biogas in Asia

    The development of biogas production and monitoring has had many twists and turns, from its early days in Germany to the heady days of support through the Clean Development Mechanism (CDM).   The fall in the price of carbon credits, which rewarded reduction in emissions of methane (CH4) - a potent greenhouse gas - and use of methane from waste as renewable energy, has hit Asia ...
