New jet fuel concept scrubs CO2 from the atmosphere

From one of the authors: "It should also remove SO₂ and chlorides from the atmosphere, and may reduce residence time of CFCs HFCs and PFCs. As far as I know, this is the only proposed alternative net-zero GHG fuel with aircraft range similar to or longer than plain hydrocarbons. (NH₃, H₂, even synthetic liquid CH₄ all have 55-90% lower energy density and require pressurization or cryogenic cooling.) The combustion product magnesia (~100 nm MgO particles) is a bodily nutrient which dissolves in lung fluids, we drink it for upset stomach and add it to drinking water to reduce acidity."

Does this work for terrestrial engines?

I suppose jet engines don't need to be restricted to airplanes, although I'm reminded of a long-ago Darwin Death Award involving such an attempt:

About a third of the way down the page is an explanation that this was a myth.

But frankly that was obvious from the story, and I have a hard time believing it was anything but a joke to begin with. I hypothesize that the Darwin Award folks got tired of people asking about the story and decided to let their readers down easy by claiming to have been fooled by the hoax as well.

There are gas turbine engines for terrestrial vehicles, there is one in the M-1A1 tank.

I can picture the chemistry working out for a diesel engine, which burn a fuel which isn't too different from jet fuel.
