Okay, Here's my crazy idea for 25 million
Edited on Sun Feb-11-07 12:54 PM by MissWaverly
They are offering 25 million for anyone who can substantially reduce greenhouse gases,
see post below. My idea is that the only way to really deal with CO2, is at the source
the point where it enters the atmosphere, well, duh, where have we heard that before. Yeah,
I know but it would have to be an efficient process to trap the CO2 at that point, most
people would buy a chimney cap, or a cap for their factories smoke stacks, if it was
easy to install and efficient, anyone else have any ideas on this?

Tycoon Hopes to Spur Milestone Research
By Kevin SullivanWashington Post Foreign Service
Saturday, February 10, 2007; Page A13
LONDON, Feb. 9 -- British billionaire entrepreneur Richard Branson, with former vice president Al Gore at his side, offered a $25 million prize Friday to anyone who can come up with a way to blunt global climate change by removing at least a billion tons of carbon dioxide a year from the Earth's atmosphere.
Branson, saying that the "survival of our species" is imperiled by current environmental trends, said the prize was similar to cash inducements that led to some of history's most notable achievements in navigation, exploration and industry. A competition launched in the 17th century, he said, resulted in the creation of a method to accurately estimate longitude.

1. Well you can't just cap it you have to treat the CO2 convert it into something else
I worked at a CO2 plant a few years ago we took the waste CO2 from the refinery Hydrogen cracker and cleaned it up and sold it as Beverage grade CO2! They then sell it to all sorts of places like Budweiser, Coke and Pepsi bottlers Did you know you were drinking Oil with every swig of that drink? Other places use it also like for Dry Ice, Disneyland uses that to keep their Ice Cream vendors carts cold -15Deg F. Then one of the unique uses I know of is they sell it to Tomato Farms that flood the green houses with it to super charge the tomatoes they get real big quickly that way, Other uses were to quick freeze food products like strawberry's burritos etc those must be one of the worst things done with it as it goes straight to the atmosphere from the packaging plant.

2. yes, the best way to deal is to make it a sought after commodity
instead of a sludge, something that has to be stored underground, etc. What about the possibility of having a type of biocell, that could digest it.

3. bacteria eats up pollutants from coal
ORNL uses bacteria to turn coal pollution into useful product

OAK RIDGE, Tenn., June 21, 1995 — Researchers at the Department of Energy's (DOE) Oak Ridge National Laboratory (ORNL) have developed a technique to convert sulfur dioxide - a pollutant from coal-fired steam plants that causes acid rain - into a useful product - sulfur. Their biological process could save energy while reducing pollution and waste.
Eric Kaufman, a researcher at the Bioprocessing Research and Development Center in ORNL's Chemical Technology Division, and P. T. Selvaraj, a postdoctoral scientist at the center, have shown that certain bacteria can convert sulfur dioxide and other sulfur oxide products into hydrogen sulfide, which can be chemically or biologically converted to elemental sulfur. They have found that these bacteria can be maintained economically because they can live off sewage.

Sulfur, a natural component of coal that is released to the air as sulfur dioxide when coal is burned, is the largest selling element in the United States. It is used to make the largest selling commodity chemical-sulfuric acid, which is essential to the manufacture of plastics, fertilizers, and other products.

4. slime eats CO2, can it live in smokestacks???
Feb. 15 An innovative project that could lead to cleaner air for all of us proves once again that to find the answer to the really big questions, scientists sometimes have to think small. Very small.

It turns out that the best candidate isn't some exotic, genetically engineered beast that loves to dine on carbon dioxide. It's just cyanobacteria, tiny micro-organisms commonly known as green slime. Cyanobacteria does, indeed, have a passion for CO2, and what's more important it can survive in the blistering temperatures of gases streaming out of a coal-fired furnace.

5. All you have to do then is reroute the exhaust
I worked at a biomass plant and to keep down the pollution we had the soot caught in the bag house it would trap the soot in bags then a pulse of air would knock down the soot to a conveyor system we would then give it to the farmers who put it in their fields as organic fertilizer.

6. that works for me
we have to do it in a way that will be easy, and doable, we can't get caught up into
some mumbo jumbo that will not work, all this talk of credits for polluting scares
me, we have to reduce pollutants not do a pr job on it.

7. or we could bury it like they are doing in Canada
put in it in something that would break it down over time????

An international research team is heading to the southeast corner of Saskatchewan to check on millions of tonnes of carbon dioxide buried beneath the frozen fi elds. They want to ensure the notorious greenhouse gas stays more than a kilometre underground in perpetuity and doesn't leak out of oil wells that have turned the Canadian Prairies into a geological pincushion.

Since 2000, more than seven million tonnes of carbon dioxide that would otherwise have risen into the atmosphere have been injected into the porous rock far beneath the farmers' fi elds just south of Weyburn. The fi rst $42-million phase of the project showed underground CO2 storage holds much promise. The next phase aims to devise the monitoring tools needed to assure the public CO2 storage can be safely managed.

Proponents of the technology say capturing and burying CO2, if used worldwide, could eliminate between one-third to onehalf of the CO2 emissions linked to climate change. Politicians and many researchers also see it as a key part of a made-in-Canada solution to the country's soaring greenhouse gas emissions.
