> This study used oil from material the researchers describe as discarded and non-edible, including the large seeds and leftover flesh, so the fuel draws on parts of the crop that would otherwise go to waste.

This statement seems disingenuous. Surely they did not invent a novel way to extract coconut oil as part of this study and not choose to publish it. Surely this is just existing byproduct that already has plenty of commercial use.

If you look at how many coconut plantations you would need to make even a measurable dent in jet fuel demand, this would be an unmitigated environmental disaster.

I want to solve climate change as much as the next guy, but chopping down all our tropical rainforests to make it happen sacrifices exactly what we're trying to save.

Yep, we've seen this sobering reality ignored in previously-hyped "biofuel" aviation stories.

Not to mention another glaring omission here: "By adding acetone to a mixture of alcohol and coconut oil"

How much energy is needed to produce those two ingredients, and the things THEY are made from?

If I were a junior-high teacher, I'd probably give this paper a C.
