It would be hard to overestimate the ignorance embodied in this remark, which seems to be an extension of the "CO2 is pollution" rhetoric: If CO2 is pollution and pollution is dirt, then all we have to do is make clean fuel.
Obviously, these are a bunch of guys that are used to getting their way, but if you can't fool Mother Nature, much less can you bully Father Thermodynamics.
If these people really believed that CO2 is killing the planet, they would hop on the nuclear bandwagon.
