However these guys are on to something.
Using it as a supplemental fuel ( 5 % ) via direct injection to Increase Octane Ratings to 150 range. It allows you to turbocharge the snaught out of an engine and could make a V6 act like a diesel it has so much torque. That is a game changer. Smaller engines, less weight, it is a positive vortex at that point, everything gets better. IMHO they are dovetailing off ADI used by our Fighter Aircraft in WWII, now with computer chip control and direct injection instead of in the carburetor airstream.
But...
1.) No one has adopted it yet.
2.) No national will to embrace it
3.) If we did, could we derive the Ethanol from Waste ( of all different sources ) rather than using Corn. That is the Million dollar question in itself.
Ethanol’s own octane number is 129 by the most optimistic measure (research octane) and this stuff about just a little bit of it, however fancily introduced, being able to boost a gasoline to 150 sounds like so much snake oil on the surface. To quote Scotty, “You canna’ change the laws of physics!”
Biowaste derived fuels are a fascinating topic, but so far it seems that such a process would need far more pure water than the world’s known resources can supply if it were to push petroleum out of contention as a fuel. Now if a microbe could be made that would do the job with seawater, the picture would change. I’d also hate to see that germ ever get loose into the oceans because it would rot all comers.
