Sorry if I offended, I didn't mean to. What I mean by hand-waving (though this definition is a bit rough): www.lexico.com/en/definition/hand_waving > biofuel production cycle is also still a carbon intensive operation, > but this can be fixed over time. I'm not an expert on these matters, so please forgive my skepticism, but I just don't see a clear path yet to a solution. Please don't take offense, but that's why I think it's hand-waving to say that with such confidence. I may have missed something, but the biofuels energy input problem doesn't seem to be as tractable as the EV battery problem has been. Back in the 1980s we could say with some certainty that the battery problem would be solved in time. Nickel-hydrogen batteries, NiMH forerunners, were used in satellites in the late 1970s. The first lithium ion prototype landed in 1985. By 1989 or 1990, I was hearing of lithium batteries as the probable future of EVs. Is there a comparable route to making biofuels with sustainable energy input? Considering how much more efficient it is already to make electricity with PV, store it in batteries, and run EVs on it directly, do you really think that biofuels have a bright future for transportation use? I mean barring blatant political intervention of course. David Roden, EVDL moderator & general lackey To reach me, don't reply to this message; I won't get it.
