In the unlikely event that emitting CO2 doesn't cause global warning, what would be left with ?
We'd be left with an energy system that produces very little pollution of any kind. That energy will also be cheaper than fossil fuel and be more flexible and more abundant forever. No more open cut coal mines that we have to repair. No more Macondo oil spills.
At the same time, instead of burning coal, oil and gas and only getting one use out of it, we will be able to use it over and over again in other products thus making those products very cheap and very plentiful for everyone.
So, what will be left with ? A whole better power system that will benefit all of mankind. And , we will preserve a precious resource to boot.
