- Virgin Earth Challenge
The Virgin Earth Challenge is a competition offering a $25 million prize for the first person or organization to come up with a way of scrubbing
greenhouse gases out of the Earth's atmosphereto avoid global warming. The prize was conceived and financed by Sir Richard Branson, a successful British entrepreneur, and was announced in Londonon 9 February 2007by Branson and former US Vice Presidentand 2007 Nobel Prizewinner Al Gore, creator of the 2006 film " An Inconvenient Truth" on climate change.cite web| url =http://news.bbc.co.uk/1/hi/sci/tech/6345557.stm| title = Branson launches $25m climate bid| publisher =BBC.co.uk| accessdate =2008-04-30]
The Virgin Earth Challenge is similar in concept to other high technology competitions, such as the
Orteig Prizefor flying across the Atlantic, and the Ansari X Prizefor spaceflight. The prize will be awarded to the first scheme that is capable of removing one billion metric tons (= 1 gigaton) of carbon dioxidefrom the atmosphere per year for 10 years (at present, fossil fuelemissions are around 6.3 gigatons per year [cite web|url= http://www.eia.doe.gov/oiaf/1605/ggccebro/chapter1.html|title=US Department of Energy on greenhouse gases|accessdate=2007-10-04] ). $5 million of the prize will be paid at the start of removal operations, with the remaining $20 million paid after the successful completion of the scheme at the end of the 10 year period.
The prize will initially only be open for five years, with ideas assessed by a panel of judges including Richard Branson, Al Gore and
Crispin Tickell(British Diplomat), as well as climate scientists James Hansen, James Lovelockand Tim Flannery. If the prize remains unclaimed at the end of five years the panel may elect to extend the period.
Around two hundred billion metric tons of carbon dioxide have accumulated in the atmosphere since the beginning of the
industrial revolution, raising concentrations by more than 100 parts per million (ppm), from 280 to more than 380 ppm. The Virgin Earth Challenge is intended to inspire inventorsto find ways of bringing that back down again to avoid the dangerous levels of global warmingand sea level risepredicted by scientific organisations such as the Intergovernmental Panel on Climate Change.
"Entrants must submit a commercially viable design (the “Design”) to achieve the net removal of significant volumes of anthropogenic, atmospheric greenhouse gases each year for at least 10 years without countervailing harmful effects (the “Removal Target”). The removal achieved by the Design must have long term benefits (measured over say 1,000 years) and must contribute materially to the stability of the Earth’s climate."
A Possible Contender: GRT Air Capture Device
According to the Earth Institute at Columbia University, [http://www.grestech.com/ Global Research Technologies, LLC] has demonstrated a
prototypedevice capable of capturing 10 tons of carbon dioxideper square meter per year; a device of 10 meters by 10 meters would be able to capture 1,000 tons per year. It is estimated that 1 million such devices would be needed to capture the 1 billion tons per year stipulated in the conditions of the prize offered by Mr. Branson. The process uses proprietary sorbents to capture carbon dioxide molecules from free-flowing air and release those molecules as a pure stream of carbon dioxide for sequestration. According to GRT, one major advantage of this new technology is that it is not necessary to site the devices in immediate proximity to a major carbon source (such as a power station); for example, the CO2 emitted by traffic in Bangkokcould be sequestered in Icelandby CO2 towers running on geothermal energy. Of course, the power source for the towers must not be a net CO2 producer, as this would partially offset the beneficial effects of the device.
