What would John Lennon have said? Given that the pro-peace and flower-power Beatles band member was highly partial to experimentation, he would doubtlessly have approved of the 'Eco-box'. Developed by Origo Industries, a British research and development startup devoted to curbing and recycling carbon dioxide, the Eco-box was originally designed to suck up waste emissions from vehicles and convert them into bio-fuel. But, in a classic eureka moment, Origo founder Ian Houston realised the potential of switching the focus of the technology from vehicles to people. The Eco-box has been redesigned to perform a task that, until now, would have only been found in the realms of science fiction. The technology uses an intricate process to capture CO2 emissions - including the breath exhaled by a building's occupants - for recycling into bio-fuel that can be used to generate electricity. Origo has secured a deal for a pilot implementation of its Eco-box at Liverpool John Lennon Airport, in northwest England. Installation in the terminal building started in January and operations are slated to commence in the summer. CO2 emissions from within the airport terminal will be extracted from the building's air-handling units by a photo-bioreactor, an artificial environment that houses and cultivates algae. Emissions will then be absorbed by the algae in the device, which accelerates their development into biomass, a renewable organic matter that can be used as fuel. It is predicted that 250 litres of bio-fuel a day will be collected through the pilot programme. That fuel will be used for the airport's heating system and to help power its diesel vehicles. If the Eco-box system runs smoothly, a larger installation could be set up, eventually yielding up to 3,000 litres of bio-fuel daily. The resulting fuel may seem uncomfortably like 'poo power' - the recycling of cow dung and gas into energy - but the Eco-box is good news for travellers who feel guilty about their carbon footprint. Up to 9 per cent of the greenhouse gases attributed to climate change comes from aeroplanes, which dump pollutants directly into the high atmosphere. In time, Origo wants to harness the power of the Eco-box to produce aviation-grade bio-fuel, fitting in nicely with a long-held goal of the aviation industry, which is pumping money into an array of initiatives in the hope of generating more eco-friendly jet juice. The oil industry continues to tell us that people will not become completely wedded to alternative fuels any time soon but globalisation analyst Tom Friedman says we should try to speed up the process all the same. 'We would never have got to the moon without daring to dream and taking extravagant risks,' Friedman says. Origo's clammy innovation could well represent progress. And let's face it, nobody said the green revolution had to be pretty.
