Turning CO2 into fuel

[Cow Poke]

Calling something simply false without a coherent response is an emotional response.

Meh... I think you're being too sensitive.

Carry on!

That would be Hydrogen DIoxide.

That's what I said

[Cow Poke]

That's what I said

Yup, I saw it! That's what he sad, alright, right after he said that other thing!

You never saw any "other thing"

[Sparko]

That's what I said

Actually I told you wrong, on purpose. It is really dihydrogen monoxide.

That's wha... oh, never mind. Too much effort.

No, it's a short response. Not inherently emotional.

Yes , anything we do will have a positive effect, but that does not mean it will resolve the problem. I did remotely propose that we should not do everything possible to reduce our carbon imprint and reduce the impact of increasing CO2 output from human sources.

? Is there something missing here? Seriously, I'm not clear what you mean and wonder if a contraction got left out.

Hydrogen dioxide has killed waaaaay more people ...

The subscript is on the H, not the O...

Your response is a bit emotional and over reacting. I will post references. I believe the 2019 UN report came to these conclusions.

Using CO2 in a process to produce energy requires an energy source, and heads up the only practical energy source is the sun.

It's based on having interviewed multiple climate scientists over the past decade, and having read the peer reviewed literature on the topic extensively. I'm not sure why calling something false that runs counter to all that qualifies as "emotional".

I have no doubt that you can find some quotes from people who will support your claim. I'm just pointing out that your claim is that they represent the majority of scientists; they simply don't. Look up scientists like Katharine Hayhoe, Gavin Schmidt, Andy Dessler, etc. and see what they're saying about mitigation.

We've got multiple practical energy sources. Geothermal, wind, nuclear, solar (both PV and concentrating), and hydro are all largely carbon neutral, and at least two of those are not dependent on the sun. If we end up building those in excess to our needs, then processes that remove CO2 from the atmosphere could potentially be economically viable.

As for this particular process, i'm not overly excited. Carbon monoxide isn't especially useful for producing fuel. It is, however, an important chemical feedstock that can be used in a huge range of processes, so this catalyst is potentially valuable. For fuel production, copper is a much better catalyst, as it can take CO2 directly to methanol or even ethylene. The issue is that the catalysts are relatively short lived before they get fouled by reaction byproducts, so most of the work has gone into trying to structure copper-continuing surfaces so that this is less of an issue.

There's a rather extensive body of literature on it.

Looking up one reference shows that copper and cerium oxide may make the best of both worlds...

Like the Lurch not a coherent response with references. The UN report was pessimistic as to what we are capable of and what is needed to turn global warming around



More to follow . . .

Wait, did you mean H2O2? I keep telling you, stop drinking stuff on the pharmacy aisle - hydrogen peroxide ain't good for ya like that!

Better than H2SO4

Which you tried to talk CP into chugging! You'd think the label screaming acid or the sulfur smell would clue him in, but nooooo...

Good thing he dumped it in that solo cup first...
