What we're discussing is people using search engines to identify mechanics. This is not a thing that has been built.
This is an idea, not a real thing.
You haven't shown any actual examples of this having been built.
We can see that Wikipedia page, sure, but there are lots of Wikipedia pages for things that were never built. Those are not real things. It has to have existed to be real.
It's kind of wild having to explain what the word "real" means.
If these devices are real, can you show me one that actually exists or existed, instead of Wikipedia pages talking about what they would be?
The page referenced does not mention any real ones.
It seems like you're making claims that they are real, to respond to someone asking for examples, and didn't give any examples
I have to admit, it's pretty exhausting how solar fans always end up relying on devices that have never been built to explain why they're the right choice
Until 10 years ago, the cheapest primary fuel was all fossil fuel based, so making synthetic fuels from fossil fuels is simply a loss in efficiency.
Only in the last decade, for the first time, renewables are a cheaper form of primary energy, creating motivation for a fuel producing energy plant R&D.
BTW: instead of raging at people with your own definition of "real" and "not real" it may help to talk in terms of Technology Readiness Level as used by eg NASA. I can see why you say electricity to synthetic fuel "isn't real" but its not "not real" in the same way perpetual motion is not real.
There sure are. Zero of them, however, produce gasoline or kerosene from air.
Many, many substances cannot be produced in chemical plants currently.

It still is, by leagues. The only reason that isn't showing up in the market is a blend of tax and subsidy (which I agree with.)
Notice what they use on the ocean, where there aren't laws.

This would be true if anyone had ever actually made it work at scale.
We're much earlier in that process than you seem to believe. The processes that people are talking about are things you can demonstrate in a beaker. These are not things that have even been industrialized at small scale, let alone at large scale.
There's decades of work involved in figuring something like that out. You don't just go "here's the money, build one."
It might be a good idea to watch some of those old Nova specials about Percy Lavon Julian, one of the greatest American chemists in history. Not only are the social angles interesting - he was a black man in the 1950s, but also a source of great wealth to an American dynasty, so you had various factions of old white people fighting over whether or not to be racist - but also his story is crucially informative here.
Mr Julian did invent and discover some plastics and other synthetics, yes, but that wasn't his important work.
His important work was taking "yeah this should be possible" and turning into "yes, we can do this cheaply at scale."
The reason he was so valuable is that that is much, much more difficult than the primary research.
I agree, the primary research has been done.
The things that people are bringing up aren't even the best examples; MIT's solar trees from 2002 do rings around this stuff in efficiency and productivity both per pound construction and per acre construction, and can be built relatively easily from already commercialized parts.
The problem is, once we're done being Cory Doctorow and being blown away by what should be possible, someone has to actually sit down and do the hard work of figuring out how to do it at scale, and then raising the money to do so, and then building several generations of factory until they get it right.
And yes, this will get done, sure.
But there's a /time/ /limit/ here.
Climate change is already putting island nations underwater, putting salt into major city aquifers, has been forcing the Army to relocate Louisianans for 30 years and now it's four states. Our water situation is getting to states suing each other and talking about piping seawater into Middle America to keep lakes wet.
I love the process you're describing, and I agree that it will eventually succeed, but I do not believe there is any realistic chance it will succeed in time for this specific challenge.

> your own definition of "real"
"Has existed" is the common, dictionary definiton of real.
Why aren't vampires real? They haven't existed yet.
Why isn't strong AI real, even though it seems like it should be possible given the simulation argument? It hasn't existed yet.
Why aren't consumer jetpacks real, even though working jetpacks have been on demo for 100 years? Nobody's made them yet.
You know that 30 foot tall robot that some guy in Japan made for a TV show? Why isn't the American response to it real, even though we have all the same technology that one guy in a garage has? Because nobody's made it yet.
Why isn't a man with one son's daughter real, even though he can have children? Because knowing that something is possible doesn't make it real.
It's very strange to me that you think this is somehow "my definition."
.
> its not "not real" in the same way perpetual motion is not real.
I never said anything about perpetual motion.
You said "isn't real", that's literally all you said. It's good that you have since clarified what you meant, but next time define what you mean from the start.
Either way the plant in Germany is still operational, the one Audi had. It's operated by Kiwi AG and it's located in Werlte.
> I have to to admit, it's pretty exhausting how solar fans always end up relying on devices that have never been built to explain why they're the right choice
Don't make so many assumptions. Pointing out something exists doesn't really give you any info on whether I am a solar fan or not. It also doesn't mean I believe it is the right choice.
Until you can show me one that's been built, that remains correct.

That's a different plant doing different work in a different city, which was built by different people and never owned by Audi. That plant produces hydrogen from water, not gasoline from air. That plant could never do either half of the work (1. from air, 2. to gasoline) that was being discussed in this thread.
The Audi plant I brought up was in Dresden, on the other side of the country, 350 miles / 550 kilometers away.

Uh.

That wasn't about you. That was about the ancestor posts I was talking to originally.
