What BBN said about it

Hank Ledger · Lead AnchorChemists at Osaka Metropolitan University tested coconut oil as jet fuel and burned blends of it in a micro jet engine, Good News Network reports.

Dale Bearman · Chief Skeptic & ContributorCoconut oil. The stuff in the back of my cupboard that I bought once and never opened.

Hank Ledger · Lead AnchorThe blends ran from ten percent coconut biofuel up to fifty-fifty with kerosene, and unburned hydrocarbon emissions dropped between five and forty percent.

Dale Bearman · Chief Skeptic & ContributorFive to forty percent. That's a wide range. Which one is it, though?

Hank Ledger · Lead AnchorIt's made at room temperature and normal pressure, with gentle heating below boiling. The team used waste coconut fruit left over from oil extraction.

Dale Bearman · Chief Skeptic & ContributorSo it's a sauce, and like every sauce, you end up using slightly more than the recipe says.

Dale Bearman · Chief Skeptic & ContributorA bigger tank, then.

Hank Ledger · Lead AnchorSlightly higher. That's the whole review.

Dale Bearman · Chief Skeptic & ContributorMy theory is the airline fits a deep fryer in the galley and calls it a sustainability initiative.

Hank Ledger · Lead AnchorMine is that the pilot announces cruising altitude, and the whole cabin smells like a chip shop.
