discounted michael kors handbags discounted michael kors handbags ´╗┐Advocates pump up greenhouse storage

The nightmare scenario for geosequestration also known as geostorage occurred in Africa in 1986. In the dark of night, Lake Nyos in Cameroon emitted a huge cloud of carbon dioxide. The gas, which is heavier than air, settled in a thick layer over the surrounding area, asphyxiating 1800 people and countless animals.

Geostorage is a seemingly sensible idea trap polluting gases from power plants, compress them until they are liquid and pump them underground. No more greenhouse gases trapping heat in the atmosphere and, therefore, no global warming.

The socalled catastrophic release is one reason why many groups, including Environment Victoria, are nervous about geostorage. But defenders of the process point out a couple of things. The Lake Nyos disaster was a natural disaster the lake is in a volcanic basin where carbon dioxide occurs naturally on the lake discounted michael kors handbags floor. No sane power producer would pump carbon dioxide and other waste gases into a lake ocean geostorage is possible but not popular. It would be pumped hundreds of metres underground into porous rock.

The rock must be sandstone or a similar bedrock solid and large enough to lock in the waste, yet porous enough to accept thousands of tonnes of liquid carbon dioxide being pumped into it daily.

Geostorage defenders say a release would be unlikely, and would not be a catastrophic release but a leak through, say, groundwater that could be plugged.

There are a number of sites in Australia where geostorage is possible, one of them in Gippsland. They could absorb Australias greenhouse gas emissions, at current rates of production, for 1600 years.

Peter Cook, the chief executive of the Cooperative Research Centre for greenhouse gas technologies, said yesterday that only the United States and Canada had implemented geost discounted michael kors handbags orage on land. Australia would be the third if it goes ahead. Norway pumps gases below the seabed of the North Sea. No existing geostorage scheme has leaked, he said.

He admitted he could not offer a 100 per cent guarantee that geostorage would not leak, but was nevertheless confident of its safety. Weve got to talk to the community about this, add discounted michael kors handbags ress their concerns, tell them what were doing and why were doing it. discounted michael kors handbags
