UK firm develops jet fuel made from human poo | The starting material is generated in excess and available in plenty. It is a win-win for everyone that the waste is repurposed.::undefined

Another stupid fuel idea. How many #2s do you need to fly from New York to Los Angeles? Probably a shitload...

But seriously, this is just another idiotic Idea. Yes, you can make fuel from a lot of sources, but neither the quantity is there, nor is this in any way efficient or cost-covering.

I once calculated that we would need to cover each and every square centimeter of agricultural area in my country with rapeseed plants without crop rotation to produce the bio-fuel that the jets in my country burn. And that does not even include the energy needed to plant it, harvest it, and process it.

Fun thing about calculations is that if you write them down you can pull them out and show it to people who are skeptic about your claims, like I am being right now of your claims.

I actually would if it had not been on the site that should not be named, and which has the most shitty search engine. Maybe I'll try Google, if my posts are still there.

That's a lot of Canola oil!

I mean I'm pretty sure a water treatment center can spare some shit for this test

This might actally power a few dozen flights a day nationwide. All the other ones will still have to rely on dead dinosaurs.

Your claimed calculation is very vague, I have to say I don't believe for a second you actually did that and it's laughable you're claiming you did

When someone tells me that they've noticed a fundamental flaw that all the leading minds in the field have not it does not lead me to think that the field itself is flawed rather the person I'm speaking to's understanding of it.

Of course we understand that it's not all going to come from one source but where there are waste products like stalks and leaves left over from food production, poo, algae, and etc it makes sense to work towards using all of those so we can transition away from the extracting oil and gas.

Yeah, screw every effort to get us away from dependency on fossil fuels, am I right?

[–] Treczoks@lemmy.world 1 points 8 months ago

No. I just expose that aviation at the current level simply is not sustainable in any way.

They’re going to install more bathrooms on the planes and serve mexican bean salsa at boarding. That way the fuel can be made in flight.
