Arctic ice set for another all-time low

August 30, 2008 The global warming debate will get even hotter in the near future with the news that current observations from ESA's Envisat satellite suggest that the extent of Arctic polar sea-ice may this year shrink to a level very close to that of last year's record minimum ice cover. Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. This animation is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced Synthetic Aperture Radar (ASAR) instrument aboard Envisat. The dark grey colour represents ice-free areas while blue represents areas covered with sea ice. The image at right shows sea-ice coverage as of mid-August 2008 with the red line indicating the all-time minimum Arctic sea-ice coverage in September 2007. Anyone know of any DIY Ark-building courses? Read More

Greencore's solar powered air conditioner

It's an idea that makes perfect sense - when it's hot, the sun is out, so why not utilize that energy to help cool down. Californian based Greencore has developed a hybrid solar-powered air conditioning system for both fixed and mobile applications which can cool a room up to 600 square feet in size using a single 170 watt solar panel, or switch to using power from the grid when necessary.

Clinton Foundation considers 5,000MW solar station in India

August 14, 2008 According to Treehugger and The Business Standard, the US-based Clinton Foundation is currently in talks with the Indian government to undertake the world’s largest single location solar project. Costing around US$475 million and with an estimated output of 5,000MW (5 gigawatts), the Gujurat-based “Integrated Solar City” would rival even the biggest coal-fired power stations. Read More

Carbon Capture: a bridging technology too far?

Carbon capture and storage is a climate change mitigation technology characterized by sporadic and unreliable government support and plagued with accusations that it will worsen the environmental disaster it seeks to address. Yet, despite the negative stigma, CCS has been labeled by the IPCC and the Stern Report as an essential measure in reducing the impact of fossil fuels. Gizmag's Kyle Sherer takes a closer look.

London's famous coal power station about to get new, green lease on life

June 25, 2008 A controversial development proposal now under consideration aims to turn London's iconic but defunct Battersea Power Station into a carbon-neutral biofuel power plant. The proposal also includes a 300 meter-tall residential tower featuring solar powered climate control and a glass 'eco-dome' that would allow residents to grow tropical roof gardens even in London's distinctly non-tropical weather. But is it a revolutionary plan to revitalize an old collapsing fossil fuel plant with a new green lease of life, or simply a grandstanding attempt by a property developer to build an ultramodern skyscaper in old London town?

The TTxGP - the first clean emissions Grand Prix

June 25, 2008 The world’s oldest racing venue, the Isle of Man, is set to reinvent itself by holding the world’s first clean emissions Grand Prix. This new and very exciting chapter in auto racing history is set to begin next June (2009) when the, the TTxGP, will be held over just one 37.7 mile (60.7 km) lap of the famous Isle of Man TT circuit. The traditional world of motorsport has been slow to grasp the urgency with which the world needs to clean up its petroleum-burning act, so a new group is planning the world’s first Clean Emissions Grand Prix race. Regulations are due in about a fortnight from now, with the intention of showcasing a diverse range of clean emission two and three wheeled vehicles capable of reaching Grand Prix race speeds. The event will be staged during the traditional TT motorcycle races and there are plans to offer the event internationally as part of a series.

Quantifying the benefits of biofuels

A team of researchers from the University of Washington researched the impact on soil fertility and effects on food supply when fuels based on crops such as corn and soybeans are mixed with fossil fuels. They discovered that the large amounts of energy required to grow corn and then convert it to produce ethanol had a net energy gain that was modest and that corn-based ethanol was the worst offender amongst the alternative energy fuels.

Designer fuel offers more mpg, less emissions, less cost

Now here’s an interesting solution to the problem of reducing emissions using the same fleet of cars we have, but by using different fuel. Airplanes need high octane fuel and the octane rating has until now been achieved by adding tetraethyl lead, but that will be outlawed from 2010. Ethanol achieves the same octane rating boost but is unsuitable for use in aircraft. To solve the riddle, the newly announced SwiftFuel© uses ethanol to produce a designer fuel with a 104 octane rating that has no ethanol in it. It runs fine in any existing plane (or car), and is a low emission, alternative made entirely from biomass that has 15-20% more energy per litre than petrol, so your plane (or car) will get better mpg too. And it costs half as much to make as current petroleum manufacturing cost. What’s the catch? Read More

"Avalanche effect" research promises greater solar cell efficiency

Research continues to improve efficiency in solar cells, whilst simultaneously finding ways to lower the costs of module production. The latest research from TU Delft and the FOM Foundation for Fundamental Research on Matter surrounds the use of semiconducting nanocrystals (crystals with dimensions in the nanometer size range) to demonstrate a phenomenon called the “avalanche effect” which has the potential to significantly boost solar cell efficiency.

StatoilHydro to build 2.3MW offshore floating wind turbine

The world desperately needs viable sources of renewable energy and wind power is among the most promising solutions, but one downside is that turbines can be considered a blight on otherwise picturesque landscapes. The solution seems obvious enough - move the towers far out to sea where not only are they out of sight, but where the wind is at its strongest and most consistent. We first encountered this idea back in 2006 when we examined the efforts of MIT researchers to integrate a turbine with a floating platform similar to those used by offshore oil rigs. Now news that Norwegian oil and gas company StatoilHydro plans to invest around US$80 million to build a full scale offshore floating wind turbine. Read More

Thin film solar manufacturing breakthrough

Thin film solar cell production breakthrough

May 15, 2008 Advancing a viable market for photovoltaic solar energy involves a balancing act between creating efficient solar cells and at the same time reducing the cost of the manufacturing process. Solar efficiency has been demonstrated to levels as high as 22% (a record set by SANYO last year), and although HelioVolt Corporation's latest announcements concern technology that is only delivering 12.2% conversion, the company has made great strides on the other side of the equation. Its proprietary FASST reactive transfer printing process has produced solar cells in a record setting six minutes, according to HelioVolt that's 10 to 100 times faster than current production of thin-film photovoltaics and could lead to manufacturing costs of less than $1 per watt.

Giant solar lily pads

May 13, 2008 Peter Richardson from Scottish architecture firm ZM Architecture has proposed using Solar Lily Pads on Glasgow’s River Clyde to harness the sun’s rays and send electricity to the city's grid. The concept has taken first place in the International Design Awards, (IDA), ‘Land and Sea’ competition. The lilypads are designed to be moved and dismantled easily as they are simply tethered to the river bed, with integrated motors used to rotate the discs for maximum exposure to sunlight throughout the day.
