I wonder how long it will take for stories to start appearing about these ships suddenly needing emergency engine overhauls?
Not sure, biodiesel from soybeans has good lubricity, and works really well. It’s not cost effective though.
More than just the cost of the fuel (which is totally stupid) I worry more about some of the biofuel reaching its cloud point in a jet fighter at 40,000 feet and turning the thing into a lawn dart!
They probably won't; Diesel engines are pretty dang robust. So much so that I am somewhat confused as to why these are costing so much... especially when you can look up on the internet people making their own.
