Remember this from Freedom TM?

A few days ago a fan of my DAEMON books reached out to let me know that a technology he first learned about in my 2010 novel, *FREEDOM TM (the sequel to Daemon), is now showing up on *roof tops*. A tech startup named Aircela is building direct-air-capture reactors to generate liquid fuel from solar energy, water, and ambient air. The machine is about the size of a refrigerator, and they're deploying units on rooftops in New York City.

*DARKNET German edition

Some of you may recall this technology from Chapter 6 of FreedomTM. Back then the tech was still being researched by Sandia National Laboratory, which gave it the unwieldy name 'Counter Rotating Ring Receiver Reactor Recuperator' (or CR5 for short).Aircela appears to have commercialized the technology, and it's worth noting that Sandia Lab's article predicted in 2007 that "this invention is probably 15 to 20 years away from being on the market." Well, it looks like they're right on target!

I firmly believe solar power satellites (SPS's) will be the best path to abundant, clean energy here on Earth, however, there will always be a need for energy-dense, liquid fuels in certain applications. Carbon-neutral, solar-to-petrol technology fits that bill, and I can envision a time when most gasoline and diesel is derived using this method, with the cost of removing the carbon from burning this fuel being factored-in to its sale price.

Aircela

@DanielSuarez This is impressive. I would have thought that managing the reaction products would have been too risky to commercialize. As a political aside and having worked in government research labs, people who criticize the money spent on primary research on peaceful technologies really do not understand that so many of the technologies we use went from pipe dream to "magic" to taken for granted, purely because of government R&D funding. I would expect that Aircela was a STTR (small business tech transfer) out of SNL. (I had that specific mention of peaceful technologies given my background in military labs. Nearly all my work was dual-use. There's a lot of money that goes into things that will benefit society, but there is a lot of money that goes into weapons systems too.)
@DanielSuarez Unfortunately, I never finished the sequel (Darknet). The torture and mutilation of the main character was too much.

@DanielSuarez They say 75kWh per gallon. That's pretty impressive: That much gasoline has about 35kWh. Of course, you cannot extract that much as work, thanks to Carnot.

That said, putting 75kWh into an EV will give you about 180 miles...

But as you said, sometimes you need liquid fuel.

@ascii158 @DanielSuarez burning this fuel in cars is completely inefficient and will always be expensive. You need these eFuels for airplanes, chemical and steel industries. It is a solution, but not for cars. There you can use the solar power directly with something like 95% efficiency from well to wheel. I mean solar panel to wheel.
@DanielSuarez I don't like what that portends... considering many of your other predictions 😬
