September 14, 2007 General Motors have released details on stage four of their HydroGen fuel cell vehicle development program. Over the next 18 months, over 100 fuel-cell powered HydroGen4 vehicles will be tested internationally in a range of driving environments and conditions. The question remains though, is Hydrogen likely to become a viable alternative to petrol? Read More

Turning beer into biofuel: researchers examine alcohol by-products as a source of alternative energy

August 28, 2007 The debate surrounding the benefits and perils of biofuels continues with by-products from the alcohol manufacturing process offered as the latest solution in the search for alternatives to fossil fuel. A proposal for a new research project to be completed at the University of Abertay Dundee in the UK has outlined a concept for cars to run on residues from beer and whisky production. Read More

U.K. team researches thinner, cheaper solar cells

August 24, 2007 Enough solar energy falls on U.S. soil to provide 500 times the country's energy needs – but the cost of harvesting this free and sustainable resource is preventing people from using it to power their homes. That’s why scientists in the sunny U.K. are excited about the possibility of thin-layer photovoltaic cells that could bring the price of solar energy down and make solar cells a viable addition to the average home.

August 21, 2007 In an effort to prevent an impending energy crisis, industries are considering various alternative energy sources with which to continue generating power whilst reducing environmental impacts. Biofuels are one alternative being adopted within the transport sector, but some experts are warning that biofuels may do more harm than good. Read More

Bioengineers rebuilding bacteria to produce crude oil

August 2, 2007 If you ever doubt the creativity of modern science, just throw a serious challenge at it and watch the myriad responses you receive. Rising oil prices and historical data are signifying that Hubbert’s “peak oil” may be upon us, and the rush is on all over the world to find viable alternative energy sources to replace the dwindling crude that’s powered us into the technology age. But what if we could just ‘grow’ more oil? The deadly bacteria E. coli, might seem like an unlikely ally, but scientists in California are claiming they have successfully genetically manipulated the deadly bug and a host of other bacteria to produce pure hydrocarbon chains that can be processed into biofuels. In fact, they’re getting so good at it that they can coax the bacteria into producing a substance that’s exceptionally close to crude oil – minus the sulfur impurities that taint the oil we pump out of the ground - and ready to be put through a standard refinery to produce petrol, diesel, jet fuel or any other petroleum product. There’s also talk of other, far more pure and powerful fuels that need no further refinement before they go to the pump. Could the next great oil barons be bug farmers? Read More

Magnetic levitation promises huge efficiency gains in wind power generation

July 31, 2007 Sustainable generation of electric power is the key to realizing the vision of a world free from dependency on fossil fuels – the challenge is to ramp up the production of electricity to a level that can begin to approach the energy we get from burning coal and oil, without the perceived dangers of going nuclear. The combined threats of Peak Oil and global warming are spurring science into a furious new age of innovation. With almost daily breakthroughs in solar energy capture, battery technology and tidal energy harvesting, but the biggest contribution to green power thus far is coming from wind farming. The common windmill design used to capitalize on air currents, while centuries old, operates at around 1% efficiency in terms of the power it harvests from the wind, due to the deflective blade design and friction losses. But a new technology unveiled last year in China seeks to dramatically boost the output of wind-driven generators by using the virtually frictionless advantages of magnetically levitated turbines. Since there’s virtually no touching of moving parts, the Maglev wind turbine requires far less servicing than a traditional windmill – which dramatically lowers the operating costs to under five U.S. cents per kilowatt-hour. If projections are accurate, giant 1-gigawatt versions of these machines could have a 12-month ROI - a scenario sure to catch the eye of investors worldwide. Read More

Tidal energy generator to be built in Northern Ireland

By Loz Blain

June 28, 2007 The tidal motion of water offers us an amazing source of energy - it's immensely powerful, predictable, reliable and can be harvested with no emissions and very little impact on the environment. Following successful testing off the coast of Devon, Marine Currrent Turbines is set to begin construction of the world's largest ever tidal turbine system off the coast of Northern Ireland - kind of like a wind farm that sits underwater. The 1.2MW generator will push enough power back into the commercial grid to supply 1000 homes, and will serve as a prototype commercial test of this clean, sustainable energy source. Read More
