CO2 is an oxidation product. It can't be broken down without the use of energy. Plants do it for the carbon content using energy from the sun. The amount of energy used to break it down will always be more than the energy we got from burning the carbon in the first place. This is because heat is always released in both processes.

It doesn't matter what catalyst or process you use, energy is always required and always lost.

BEST SOLUTION - STOP USING SO MUCH ENERGY.

There are hundreds of things that could be done other than Western bashing to solve the problem, Instead of dumping wast water into our rivers ,lakes our drinking water, every drop should be used to grow more trees Scientists have looked carefully at each of these factors. The only one where the data matches up is greenhouse gases -- levels of these gases have risen sharply as we burn more fossil fuels. If liberals were really interested in solving the problem, and not interested only in bashing industrialized nations, They would look for real solutions, The most logical solution is to increase oxygen in the atmosphere, rather than slow industrialization. One average size tree produces enough oxygen for breathing of 25 people. The average new home built would add 5 new trees to the world's best oxygen producers A simple solution in the US Is to force the US Government to release some of the millions an millions of acres, they are holding away from the people to control demographers for political reasons. GB advocates have already starved 100 millions Africans to death with their Western bashing agenda. Trees not only pump oxygen into the atmosphere they also pump moisture into the air. It doesn't rain much any more in Africa because most of the trees have been cut down in Africa and the Mid east.
