Emissions Control

Calcium carbonate in powder form

Expensive carbon capture and storage (CCS) projects are gaining momentum around the world as a way to combat greenhouse gas emissions (or is that sweep them under the carpet?), India’s Economic Times has reported that a team of Indian scientists have discovered a naturally occurring bacteria that could help fight global warming by converting CO2 into calcium carbonate (CaCO3) - a common compound found as rock all the world over.  Read More

The Waste2tricity process

It’s common knowledge that the majority of electricity generation and waste disposal methods currently in widespread use are not very environmentally friendly. New British venture Waste2tricity aims to kill two environmentally damaging birds with one stone by taking carbon based waste, either municipal solid waste (MSW) or waste from business and industry, and converting it into clean electricity, thereby reducing the amount of rubbish going to landfill and potentially making a significant contribution to the UK electricity supply.  Read More

Less waste = reduced construction costs

When we think green house emissions, fume spewing factories and highways choked with gas guzzling vehicles are usually the first images that spring to mind, but it may surprise some readers to learn that buildings represent a sizeable chunk of our collective carbon footprint. In America, it's estimated that buildings contribute to 36% of energy consumption and 30% of green house gas emissions and it's an area that's ripe for improvement. Innovative American building company Vitruvian is doing just that by offering a full service green building system that utilizes pre-engineered modular construction consisting of inter lockable panels to form a complete, weather tight building shell. As well as delivering extremely low energy bills, Vitruvian has calculated that if its process was used for all building replacement and construction in America between now and the year 2030, its environmental impact would be the equivalent of removing more than 80 million cars from the road.  Read More

Australian Scientists developing spray on solar panels

Researchers in Australia have started a three-year project to develop a spray-on coating for solar panels and more efficient cells that are less costly than today's PV. Australian National University (ANU) is working with new Australian solar company Spark Solar and Finnish materials company Braggone Oy on the method, which could be commercially available by 2011.  Read More

NASA’s Orbiting Carbon Observatory spacecraft and its Taurus XL launch vehicle are undergoing preparations for liftoff on February 23. The Orbiting Carbon Observatory’s mission is to collect precise global measurements of carbon dioxide (CO2) in the Earth's atmosphere to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas - important because its the leading human-produced greenhouse gas driving changes in Earth's climate. This improved understanding will enable more reliable forecasts of future changes in the abundance and distribution of CO2 in the atmosphere and the effect that these changes may have on the Earth's climate.  Read More

The Windspire

While wind turbines are a clean, green way to generate power, they can be a bit of an eyesore and require quite a bit of room meaning, more often than not, they need to be located in sparsely populated areas far from where the generated power is actually needed. We’ve looked at AeroVironment’s innovative urban solution as well as StatoilHydro’s HyWind. Now a look at another innovative product - Windspire. The Windspire, from Reno, Nevada based Mariah Power, combats the large footprint problem by employing a propeller-free design that makes it ideal for rural, suburban, and even some urban residential environments.  Read More

Ferrari goes solar

When you think Ferrari you think fire breathing supercars and F1 racing, not environmental consciousness, but the renowned marque is looking to boost its green credentials with the unveiling of a new photovoltaic system at its Engine Mechanical Machining facility in Maranello, Italy. The 210,000 kWh photovoltaic system is part of an ongoing sustainability program which also includes plans for a new tri-generation plant which the company says will cover "virtually all" of its electricity requirements and cut its annual CO2 emissions by 25-30% compared to the present levels when it becomes operational mid-year.  Read More

Audi's Sportback concept

January 13, 2009 While the firebreathing 5.2-litre V10 R8 supercar is clearly the performance king of Audi's Detroit NAIAS lineup, the Sportback concept unveiled does an excellent job of marrying performance, economy, stunning looks and practicality. Its 3-litre, 6-cylinder direct-injection turbo 'clean diesel' engine puts out 225 horsepower and 550 Nm, for a top speed over 150mph - and yet its average fuel economy nearly tips 40mpg. Ultra-low CO2 emissions are the result of smart decisions throughout the car, from the advanced exhaust emissions control, to electric systems like the power steering that consume no energy when they're not immediately in use, to automatic engine stop-start at the traffic lights and power-smart sunlight-white LED headlights. The Sportback's ultra-clean lines and fastback hatch somehow make this four-door coupe look sportier than some of its two-door contemporaries. Beautiful.  Read More

The Lexus HS 250h luxury hybrid

January 13, 2009 In keeping with the strong theme of efficiency over gas-guzzling muscle at this year's Detroit NAIAS auto show, Lexus has introduced a new hybrid sedan to its lineup, slated to go on sale in Q3 2009. 30% more fuel-efficient than anything else in the Lexus range, the 187-horsepower, 4-cylinder HS 250h is an acknowledgement by the biggest-selling luxury car brand in the USA that even the cashed-up luxury market wants to control its use of fossil fuels. While the HS 250h is miserly on fuel (Lexus claim it will drink less per mile than the tiny Smart Fortwo) it's still a big spender on the interior, with some serious driver assist features, heads-up display, radar-governed cruise control, parking cameras and a voice-controlled nav/premium audio system.  Read More

nPower PEG

Battery running low on you're mobile phone? Sounds like it's time for a walk. That's the reality of the nPower PEG, a personal energy generator that, like battery-less flashlights which require shaking to produce energy, puts Faraday's Principle of Electromagnetic Induction to work to create a totally renewable energy source for charging your handheld electronic devices.  Read More
