If you think that we can eliminate or reduce CO2 emissions by "splitting" 
CO2 molecules into Carbon and Oxygen, you are simply demonstrating ignorance 
of the law of conservation of energy.

The energy produced by burning fossil fuels is released when Carbon and 
Hydrogen joint with Oxygen in the air to produce CO2 and H2O. The only way 
that you can split these molecules apart again is by supplying more energy 
than was released when they were created, meaning fossil fuel plants would 
consume more energy than they produce, rendering them useless.

If you are really unfamiliar with the law of conservation of energy - which 
is primary school science - you are probably better off not posting your 
ideas to science newsgroups.
