### Richard Branson's carbon dioxide competition

Vacuum cleaner for \$25 million Design a vacuum cleaner and Richard Branson will give you 25 million USD. Figure 1: A large, floor-mounted "zero emission" or "low emission" system is going to cost about \$250,000. These systems are popular in Southern California. This is a three-cycle vacuum vapor degreaser system from Branson Ultrasonics. These systems are often purchased where air quality regulations make the use of traditional, open-top cleaning systems impractical.

The only subtlety - one that makes the previous paragraph and the picture useless - is that the vacuum cleaner must suck greenhouse gases from the atmosphere. As you know, the planet is facing emergency called the global warming. For example, New York state is under 100 inches of snow only, Arizona had its coldest January in 28 years, and Colorado had the coldest January ever. I hope that the wise reader who wins Branson's contest will dedicate 1% of her award to the blog. ;-)

For example, you can try to create a working model of a synthetic tree by Klaus Lackner (click):

To win the award, your device must absorb one billion tons of carbon per year. One billion tons of wood is slightly above a cubed kilometer. The total carbon emissions are just 6.5 times this - 6.5 billion tons a year (or 20+ billion tons of CO2).

Many people are already trying to solve the homework problem. How do I know? Well, many of them Google for is there a way to extract carbon dioxide. ;-)

A postdoctoral guest blogger of politically correct sex at RealClimate uses the contest to attack Paul Crutzen, a Nobel prize winner, because his proposal is not about removing the dirty species called homo sapiens and his dirty creation from the face of Gaia but instead about adding something. ;-) Well, this is how the environmentalist radicals think.

1. Sir Richard Branson wants to give a person 25 million dollars to produce a device which will eliminate 1 billion tonnes of CO2 per year? Well, if a brilliant individual finds a way to convert CO2 into it's basic ingredients of carbon and oxygen or scrub it out of the ambient air, then how are they going to dispose of a cubic kilometer of carbon? By definition, a cubic kilmeter is 10 to the 9th power or simply put, the size of a mountain.

2. If the ocean were seeded with iron powder by planes, that would cause seaweed to grow like crazy. Seaweed consumes a lot of greenhouse gases and renews most of earth's oxygen already. A bit of iron and fertilizers in the right places could help.
