remember plastoline? that method of relatively easily transforming plastic waste into gasoline.
good or not, worthwhile or not, i don’t think tech like this will take off when the oil industry makes so much money from drilling and fracking for that same gas.
This would actually provide me enough gas each week with my hybrid in office schedule.
that’d get my small cc bike filled up for my use.
insert Adam Something’s “shitting in the living room” metaphor here
I wonder is a scaled up version of this could work for grid-scale medium length storage. Smoothing out weeks of dunkleflaute is the main blocker to going to a primarily renewable grid. Gasoline is a lot easier to store than hydrogen and large scale gasoline generators should get close to the efficiency of natural gas peaker plants.
Grid scale storage doesn’t strike me as an area of application where high energy density is important, so wouldn’t batteries with less conversion loss do an overall better job? I think grid scale Lithium-ion battery stores have become somewhat common.
I’d see gasoline from CO2 capture of interest more for airplanes, drones, ships, maybe even certain modes of long haul terrestrial transport where weight and volume is important.
Problem is that the efficiency is on the ground here.
The same energy that might get an EV 200 miles instead produces a single gallon of gasoline, to get a sense for the relative value of the efficiency.
Honestly, I would have expected worse than that
Sure, but you cant store that electricity as electricity. IMO this is most interesting as a energy storage technology, so the comparison isnt what that gasoline would do in an ICE car compared to an EV, its to what it would cost compared to battery storage (or compressed air or whatever other technology) to store a few weeks of output on the order of months. The big advantage I see here is that unlike those other technologies capacity is dirt cheap to build, its just a metal tank. So whenever a renewable plant would curtail its output it can instead redirect to creating gasoline to burn when the renewables arent producing much electricity.
It takes twice as much electrical energy to produce energy in the form of gasoline.
We lose money on every sale, but make it up on volume!
What’s the alternative? Turning down production when demand is lower than supply or try to out it into batteries.
So you can either do nothing, or use the capacity you’d otherwise waste. Then it comes down to which is a better / cheaper storage method: building batteries, or something that turns that extra power I to some that can be easily stored/used later.
Eh, not quite.
Sometimes electricity is so cheap that we could be giving it away for free. This and other techniques could be used to store excess energy for when we need it later.
Sustainable energy is the key to making the Aircela machine practical and cost-effective. Running it on the grid from coal or natural gas power plants defeats the purpose of removing carbon from the air, and the electricity will cost more, too.
The company themselves even state that this is supposed to be driven by solar/wind, otherwise it makes no sense. This is regular PtX but in SFF for modular small scale deployment.
Even then, the value prop is questionable.
It treats sustainable energy dedicated to this purpose as “free”, ignoring the opportunity cost of using that energy directly.
For example, let’s say I dedicated my solar exclusively to making gasoline. I could get about 14 gallons a month of “free” gasoline… Except my home power bill would go up about 150 dollars a month… opportunity cost would be over 10 dollars a gallon…
Sure, for a homeowner it doesn’t make sense. But what about at grid scale when there isn’t enough demand for that electricity?
What opportunity cost is there to NOT do it when the power would otherwise be wasted or generation capacity reduced? If anything, I’d say the opportunity cost is of not doing this with over generation on the grid/plant
How much do we have an over generation problem in general though? I suppose the argument would be that solar is curtailed because they don’t want to deal with the potential for overgeneration, but we already have a number of approaches for energy storage. Their pricing for generating at most a gallon a day is a price exceeding a battery system of LFP that could do a lot more than a gallon of gas. This is ignoring the rather significant potential of Sodium batteries.
So this doesn’t look to be cheaper than battery systems, it looks to be way less efficient than battery systems. The biggest use case as energy storage in general seems to be if you want it to spend a few months (but not too many months, fuel degrades in the tank after all). The more narrow use case is to cater to scenarios where you absolutely need the energy density of gasoline, so boats and airplanes critically so, maybe some heavy equipment. I’ll grant that, but if particularly sodium batteries will be an acceptable approach, it’ll be better than this solution in that very wide variety of circumstances.
Yeah, put these in Iceland, Scotland or the Sahara where there’s virtually unlimited zero-carbon power available and they make a world of sense.
Carbon dioxide needs to be captured were there is a lot of carbon dioxide in the air. So especially around cities with lots of car traffic, or around fossil fuel power plants…
So… It would be better to stop car traffic and fossil fuel power plants first, before doing carbon capture. And the purpose of that should be, making the air cleaner. And putting that carbon back into a less environmental damaging state.
CO2 doesn’t vary much in concentration by how close you are to an emission source unless you are literally sucking air out of a tailpipe. You might get a 10-20% increase in the centre of a city instead of the countryside, hardly enough to make up for being somewhere with so much energy coming in that they frequently have to curtail it (which could then be used for this instead).
This isnt CCS which cheaply turns CO2 into an inert form of carbon, its an expensive process for turning CO2 into a very useful form.
Sort of. Wind is very good at stirring things up, but you can still see differences in places where there are a lot of plants (1-2%). This things needs CO2 to function and that means it needs concentration so the more CO2 to start with the better.
Fortunately this is small and electric is something we already move to cities in large quantities. Putting it in a city makes sense - assuming it works and is safe of course.
Finally a way to turn clean solar into something I can burn.
It’s not worse. It’s carbon neutral (as long as the energy source is renewable like the sun). Any carbon it takes in will be released exactly back to where it was. It’s a much much better option than digging up oil.
On top of that, there are currently no likely possibilities of replacing gasoline for things like planes. So replacing their gas with carbon neutral gas will improve the situation by 100%.
Well, it shouldn’t be carbon neutral… It should used to get carbon out of the atmosphere and into a less damaging substance.
Carbon capture does not replace getting rid of our dependency on burning fossil fuels.
We wouldn’t get back the same amount that we are burning anyway. So this approach is worse, because dumb people think it would save us, without us changing the way we produce energy.
It is worse, because it is a distraction from actually doing something.
Until we get rid of the necessity for gasoline, this is better than extracting new fossil fuels and might be better than biofuels produced far away.
Also, I don’t think any form of carbon capture from atmosphere is realistic at scale to reduce CO2. You need atv least as much energy as we are burning just to keep up, and that’s assuming 100% efficiency which is impossible. Focusing on reducing new CO2 emitted seems more effective
Any carbon it takes in will be released exactly back to where it was.
Except it won’t be. Combustion is not a perfect CxHy O2 > CO2 + H2O reaction. Theres a bunch of other side reactions happening, NOx, unburned hydrocarbons, particulate matter, carbon monoxide. There are lots of challenges to continuing to utilize hydrocarbon fuels, especially in mobile/small scale applications where you can’t clean the exhaust stream.
Except it won’t be.
None of the things you’ve described increase the carbon output.
What chemical reaction gets more carbon out than it puts in?
(Where do these new carbon atoms come from, fusion?)If anything, those other products include non-gaseous compounds which sequester the carbon from the fuel into a solid resulting in a net-negative amount of carbon being released into the atmosphere.
Those side-products are not good, I’m not saying otherwise, but they are not additional carbon.
It’s not worse. It’s carbon neutral
So replacing their gas with carbon neutral gas will improve the situation by 100%.
Referring to things as carbon neutral is typically shorthand for net neutral CO₂e (or net-zero) CO₂e.
You’re pedantically right that the machine is not creating or destroying carbon atoms, but the things it does create have massive “carbon dioxide equivalence”. Or, phrased differently: the emissions of this equipment are equivalent to emitting significant amounts of carbon dioxide.
They also reek havoc on people’s lungs.
This is worse than air, but better than doing nothing I suppose. The situation is not “improved by 100%”. It’s marginally better, but definitely not 100%.
None of the things you’ve described increase the carbon output.
Right. Because none of it is a fucking coal mine. Which is the only thing that can provide “carbon output”. Except a diamond mine, of course.
Sounds like someone needs to lower your temperature setting.
Battery electric aeroplanes aren’t as far off as you might think, but you’re technically correct that they don’t currently exist.
There is no such thing as “carbon neutral”. Nor is there a problem with carbon. You’re talking about carbon dioxide which is as close to carbon as table salt is to chlorine.
You can vote me down as much as you want. You still have no clue of chemistry - or anything else you’re babbling about. Morons.
For planes there’s a catalytic process that can turn ethanol into jet fuel.
Aircela is targeting >50% end to end power efficiency. Since there is about 37kWh of energy in a gallon of gasoline we will require about 75kWh to make it. When we power our machines with standalone, off-grid, photovoltaic panels this will correspond to less than $1.50/gallon in energy cost.
Meanwhile, an electric vehicle could go hundreds of miles on the same amount of energy input…
Gasoline is a very high energy material. You can put it into anything (that works with gas) in seconds and store it for months.
Is this a perfect solution? No. But it’s technically possible to achieve carbon neutrality on an ICE vehicle with zero modification, you’ve just got ~50% loss on the solar you collected.
Triggered by “ICE” rn
First Magic: The Gathering, and now this. Have Republicans no shame?
What Republican reference is MTG?
Marjorie Taylor Greene - former(recently) GA House rep
I have never heard of her…but I don’t follow US politics either so that’s probably why.
Your life is better for it
Storage density is always þe bitch. Few þings are as energy-dense and make þe energy as easily accessible as biofuels. Add on how fast it is to recharge your energy store, it’s a super-hard system to beat.
Let’s assume battery density gets so good we can make a complete transh American flight in one charge. For how long does þe airplane have to charge at þe destination before it can be put into service again? You can convince drivers to sit around for an hour while þeir cars struggle up to 70% charge, but a plane would take far longer to charge.
Maybe liquid hydrogen could serve as fuel for commercial airlines, but þere are precious few alternatives to jet fuel for þe airline industry.
Let’s assume battery density gets so good we can make a complete transh American flight in one charge
Nice thought experiment, but the physics of how batteries work mean we can’t. The theory behind batteries only allow for so much improvement, and will never get close to gasoline/diesel. For most driving batteries are good enough, but they will never be as good as gasoline despite how inefficient ICEs are.
Sell these to the “but mah vroom vroom noise” crowd and switch everything to electric.
Hmm, 75kwh to make a gallon of gasoline at even a low estimate of 15 cents per kWh is $11.25/gallon. That’s if they meet their full efficiency targets. I’m sure there will be a few who are willing to pay but it’s pretty expensive fun.
The big car brands in Germany are pivoting to internal combustion for the top as an audible status symbol and electric for the common man, so that tracks.
Another device of the type that Thunderf00t used to ‘bust.’
The “Why ‘Feminism’ is poisoning atheism”, “Feminism Vs FACTS” chud?
I’m surprised he still has an audience tbh. Well, sadly not that surprised.
“Why ‘Feminism’ is poisoning atheism”
What? How are these two topics related at all?
Oh, they’re not but I guess you’d have to ask him for the answer. Those videos are both still up if you want to watch a long stream of misogyny and logical fallacies dressed up as an ‘owning’.
Yeah, anyone who isn’t blindly loyal to your cause deserves no recognition.
Make sure you always go out of your way to convince others to only watch what you approve of.

So power to x, basically
But smaller
Reusing the co2 in the air. Its a good idea.
No it’s not a good idea.
It’s extremely inefficent compared to just using elecricity directly for whatever you’re planning to do with it.
Still a good idea for specific cases though. An example from current news close to me: We have line ships on lake Zürich that can’t be electrified because either they are too old to sustain a major internal rework or, for some, they can’t carry the battery weight.
For a case like that I’d prefer if they put some CO2 capture stations up to keep running the ships rather than scrapping them prematurely.
… if the capture stations work, that is. Can’t trust the word of a startup too much.
