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

let poo return to the earth. jets also. we don’t need poo jets adding to the crap in the air.

You're not going to stop people living their lives, visiting friends, family, and having meaningful life experiences. If we can make flying more ecologically sustainable than rail and boats then it would be a hugely positive thing in the fight against climate change.

We can stop them by taking their money away and giving it to those who need it.

No leisurely intercontinental flights until all children are free from starvation!

Stop subsidising air travel and people are gonna prefer trains and boats real fast.

To be even more doomer, people will have to stop living their lives when we run out of everything, so we might as well start winding down now.

I'd argue that private jets would have to be banned before I'd accept any regulation on economy flights to visit my family that I see every two years

Yes I know that's what you want to happen but it's not very likely, we're not really short of anything that we don't have a dozen other options for.

We'll have oceanic floating factories harvesting sunlight and turning sea water into jet fuel and carbon fibre Christmas toys before consumerism gets close to admitting defeat.

If you want to change society I'm afraid you have to do the hard thing of coming up with a better idea and convincing people to try it.

I hope we do pull off a 90th minute 720 backflip into futurist utopia, that would be mega. But until people start doing basic stuff like voting in their interest, I'm going to prepare for the worst.

You certainly can, with proper carbon emissions taxation. But you can't stop said people from voting for parties that advocate unrealistic pipe-dream technological solutions like poop jets and full-scale CCS, rather than parties who make them take the red pill and face reality and the consequences of their actions.

A lot of the time it's just processed in open air tanks to break it down (amoung a lot of other steps before returning it to water ways or used as fertilizer/burnt).

You need a pretty low pop density to have septics work for most people.

When poo is returned to the earth, it's digested by insects and microbes which use it for energy, and then emit CO2. Poo in the dirt puts carbon in the air the same as poo in a jet
