  • 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 ...

  • Turning wood chips and sawdust into a valuable solid fuel

    RUF briquetting units are the economical solution for the processing of wood chips and sawdust. Where timber is planed, turned and sanded, manufacturers end up with large quantities of wood chips and sawdust. By briquetting this material, you can recover a valuable solid fuel. Where large quantities are produced, the single briquette pressing system developed by RUF GmbH is the most economical ...

  • 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 ...

  • Airbus CEO talks about emissions, innovation and more

    These are heady times for the commercial-aircraft business at Airbus and Boeing, as airlines place huge orders for new planes. Each is working on more fuel-efficient aircraft to satisfy airlines that want lower fuel bills and regulators who want lower emissions from aircraft. Airbus Group CEO Tom Enders spoke last month to an aviation conference in Dallas and urged the industry to put more ...

  • Rise in flights will outweigh carbon cuts

    The aviation industry insists that it is making only a tiny contribution to global warming, with just 2% of global carbon dioxide emissions coming from its aircraft. The problem is the speed at which aviation itself is growing. One aircraft builder believes the number of planes in service in 2011 will have doubled by 2031. Whatever ...

  • 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 ...

  • Aircraft CO2 Standards – One Step Closer But No Take Off Yet!

    The long awaited standard for aircraft CO2 emissions made further headway at a recent meeting of the UN’s International Civil Aviation Organization (ICAO). The new environmental measure was unanimously recommended by the 170 international experts on ICAO’s Committee on Aviation Environmental Protection (CAEP), paving the way for its ultimate adoption by the UN ...

  • Enhanced acoustic material testing in a tube

    Demands from the Industry   A growing number of customers demand quieter vehicle cabins, and cabin acoustic comfort has become a major concern for the automotive industry. Optimization of the acoustic insulation performance has, therefore, been given a more prevalent role in the design process. In the aircraft industry, acoustic comfort for customers and the use of new, lighter ...

  • Time to stop subsidising the most polluting form of transport

    Late last month, the World Trade Organisation told the USA and the EU what it thinks of US subsidies to Boeing (story, page 2). Last June, the WTO delivered a similar verdict on EU subsidies to Airbus. Of course both sides claim that the other’s subsidies are worse – we can’t yet check these claims because the WTO report won’t be published for another few weeks, but it is ...

  • Three models of social change

    Can we change fast enough? When thinking about the enormous need for social change as we attempt to move the world economy onto a sustainable path, I find it useful to look at various models of change. Three stand out. One is the catastrophic event model, which I call the Pearl Harbor model, where a dramatic event fundamentally changes how we think and behave. The second model is one where a ...

  • 4 Steps to Reducing Aviation’s Carbon Footprint

    We live in an increasingly hyper-mobile society with over three billion passengers being carried by the world’s airlines in 2013, and an estimated 31% growth in passenger demand by 2017.  This accounts for hundreds of millions of tonnes in greenhouse gas emissions worldwide, greatly impacting global warming, climate change, and ultimately the sustainability of life on this wonderful ...

  • Taxpayer dollars subsidizing destruction

    One way to correct market failures is tax shifting—raising taxes on activities that harm the environment so that their prices begin to reflect their true cost and offsetting this with a reduction in income taxes. A complimentary way to achieve this goal is subsidy shifting. Each year the world's taxpayers provide at least $700 billion in subsidies for environmentally destructive activities, such ...

  • The oil intensity of food

    Today we are an oil-based civilization, one that is totally dependent on a resource whose production will soon be falling. Since 1981, the quantity of oil extracted has exceeded new discoveries by an ever-widening margin. In 2008, the world pumped 31 billion barrels of oil but discovered fewer than 9 billion barrels of new oil. World reserves of conventional oil are in a free fall, dropping every ...

  • 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 ...
