No, really, there is no such thing as "Clean Coal." The technology, otherwise known as carbon capture and storage (CCS) has NEVER been done on an industrial scale and would take many years to develop and implement...assuming it's even possible. It's ridiculous to think clean coal technology is even a remotely feasible solution to our energy and global warming problems when we have far better choices available for implementation now such as wind, solar, geothermal, etc.
Get off the clean coal bandwagon for pete's sake. Give it up. Seriously.
