#2Their technology aside, I don't think it's a good idea to put 7% of their vehicle payload on the roof. That would measurably elevate the center of gravity, which is not ideal for any vehicle that turns.

#3>Just convert the CO2 to fuel using renewable energy
That’s a nice idea but I haven’t seen a reaction that reduces CO2 anywhere, I’m not a professional chemist though so maybe I’m missing something?
EDIT: lol, yes I am [1]. I should just stick to software since I only mildly suck at that.
Also all that crazy tech sounds a bit like overkill; alkali hydroxides absorb CO2 and are pretty cheap to produce.

#4Brilliant. Now let's force the governments to put in place the right incentives. How do we do that?

#5This is too complicated and I'm not convinced, but the research paper has more details that make more sense that the short press release https://www.frontiersin.org/articles/10.3389/fenrg.2019.0014...
They don't use the collected CO2 to make diesel fuel, they make methane. Some trucks may use methane as fuel.
IIUC they don't expect every gas station to have a converted from CO2 to fuel, but to have the conversion in the operational bases of the trucks, or collect it and send it to a specialized facility.
They use the heat from the exhaust gases to power the device, the calculations are in the paper.
They say that in other projects, they use the same heat of the exhaust gases to improve the efficiency of the fuel in a 10%. So this is not totally "free".
How does this compare to releasing the CO2 (and getting a 10% of efficiency) and collecting the CO2 from the air in a central location?
How does this compare to using Hydrogen as fuel? I guess the difference is that most of this technology is buildable now, but Hydrogen storage is too difficult for now.
How does this compare with a electric truck? I guess this system gives more autonomy, but all the chemical reactions to convert the CO2 to methane are less efficient that good batteries.

Let’s wait to see if it actually works before we start threatening to put people in prison for not using it.

It is possible to convert the CO2 to methane https://en.wikipedia.org/wiki/Sabatier_reaction
but it is not as efficient as portrayed in the media. Conversion to gasoline or diesel fuel is much more difficult and inefficient.

Well that only makes methane so you need an extra step (like Fischer topsch) to get longer hydrocarbons. So it makes sense that using it that way would be way less efficient.

Start by proposing it to a goverment who is actually interested in facing cimate change
