Ceramic Tubes Promise Cleaner Energy

So the obvious question is, "what is the waste generated in the creation of Lanthanum-Strontium-Cobalt-Ferric Oxide?"

And I thought that the thing to do now is to stop producing so much CO2... Isn't CO2 a "greenhouse gas"?

If carbon dioxide has commercial potential for reprocessing into useful chemicals, why not just filter it out of the air? It may be more costly, but it may also help offset "global climate change" (giggle).

It's not so much the CO2, but where the CO2 is that has the potential for global warming. We need enough CO2 in the air to support plant life. I know we all know this; I just had to stick my 2 cents in. Sorry.

A factory that produces pure CO₂ is better than a plant that produces CO₂ plus a lot of other crap. And if your output is already pure, then you don't need energy to suck it out of the air - see?
