Firm develops jet fuel made entirely from human poo
Scientists have found a way to make jet fuel from human sewage and cut carbon emissions.

Will this require a special stool for fuelers to stand on for pumping excrement?

We are all made of stars. One tidbit I learned recently is that corn (and maybe other agricultural feedstocks) is not regarded as a viable source of SAF by the industry because the fermentation step to turn it into ethanol produces hugely-too much carbon dioxide compared other technologies.
So that is NOT evidence of “no free lunch” with green fuels. There are plenty of viable and scalable options that are carbon neutral; just not corn gas.
And I'm assuming the amount of water needed for either of those would be astronomical, although I'm not sure. It would be interesting to see the real numbers on a big scale. Too many people fall into that "see? Teslas are horrible for the environment!" trope instead of accepting that while something isn't perfect, it can be better than what we have.

That's similar to how ethanol based fuel isn't really any better than straight Dinosaur fuel but the lobbying was so intense for it that here we are.

Little did we know that our awful diets would eventually become key to American energy independence.

In the back of my mind is the White House Vegetable Garden.
There was controversy back in 2009 when elevated levels of lead were found in the soil of the garden; 94 ppm, well below the EPA level where remdiation is required, but above some definitions of hazardout, in a place where food would be grown. The suspected source of the elevated lead level was back when the garden was fertilized with sewage sludge; a practive promoted by the EPA during the Clinton administration as a way to divert mass from landfills (and is still an agricultural practice in parts of the US). The concerns about sluge come from the toxic content that comes from industrial activity, but also directly from human in the form of medication that is passed-through they body or just flushed down a drain. The sludge is effectively a concentrate of all that.
I doubt that will be a big factor for making buttfuel, but I wonder how the process will deal with those ingredients. Possibly either re-invent leaded gas, or maybe produce a "super sludge" as a byproduct.

I guess the future "green (brown) Aéroplane" will be moody, responding to prozac, xanax, ketamine et al...

I guarantee that nobody on this forum, regardless of your access to a not-regularly used fuel dump system, has as much fuel dumped as I do. As far as the spectrum of potential skeletons one might have in their military service closet, that is probably my one. Sorry ocean, you didn't deserve our poor operational planning
A "good" night might only have involved dumping a few thousand lbs

Yeah but didn’t dump it on kids, which is why you’re here and not Delta.

My last fuel dump was 105,000 pounds. The one before that was i think 55,000 pounds.
