either wait for bigger batteries, hydrogen or some super efficient material to create the fuselage.

biofuels won't work. they take too much land and are inefficient in terms of producing.

The issue with bio fuel is the following: Due to climate change the overall area for food production in the world is shrinking. Bio fuel is directly competing with food.

The solution: Ditch carbon based fuels as much as possible and replace it with electric transport.

I know that it's currently unviable to use electric aircraft in almost all use cases except short range drones. But then the solution to that problem is to rely less on air travel and transport and use land based alternatives.

This is about vectors and incentives. Investing in bio fuels to get a 100% replacement for fossil fuels is not going to work and it only stalls what actually needs to happen which is a radical transport system change.

Will this produce better smells?

Aviation uses around a million metric tons of jet fuel per day.

If you thought habitat destruction from palm oil was bad, that would be nothing compared to coconut oil making up any significant fraction of jet fuel.

The question is which habitat destruction is worse? That which is already happening at scale for oil, versus what would happen if we lean into this in any meaningful way.

I don't think the answer is obvious. And I think many of us are blind or numb to environmental harms of oil outside of carbon exhaust and the occasional spill, simply because we've accepted it as status quo.

An oil well is quite small Area wise compared to the amount of acreage you would need for a coconut plantations to replace the same amount of energy output.

The issue with oil is CO2 and other green house gases and then the occasional oil spill or leak. Land area wise they don’t take up much space

Ah, the modern debacle, shall we choose this kind of shit or that?

we've been working on biofuel to replace fossils forever, hopefully it leads to something if not jet fuel specifically.

Yeah, but until it matches kerosene in price and availability (how many coconuts per aeronautical mile?) it won't actually be an alternative

Just intuitively I doubt there's nearly enough coconut oil produced to replace any meaningful amount of jet fuel. I scanned the article and didn't see this addressed, but may have missed it.

Various other bio-fuel and synthesized replacements for petroleum-based jet fuel have been tried and are in development. The aviation industry is very slow to approve and adopt changes.

The point isn't to make cheap jet fuel. The point is that to the coconut processor (someone who makes food or whatever) your "coconut tailings" pile is a big liability. The environmentalists could start screeching any day without warning, that's a big risk to your business. Waste that costs you nothing could cost a lot. You might be able to sell it as loam or fertilizer or whatever. But then they'll screech that you need to buy somme compliance solution. Just shipping the damn thing off to the next guy who'll squeeze some jet fuel out of it is real attractive because then the rest of the tailings become his problem. Maybe he's in a better jurisdiction. Maybe it's more inert at that point. In any case it's a liability off your books. The jet fuel just needs to be cheap enough to make this whole process cheaper than whatever way you were dealing with it before. It's like this the world over. Whether you're selling coconut scraps to the people who'll squeeze the oil out of them or strawberry waste to the people who'll make dyes and fragrances it's all the same.
