Alternatively, develop a reasonably cheap alternative and then release it to the public domain as a service - while you won't make any money that way, you could release the stranglehold that petrochemistry has on the industry - somewhat.
It would be similar to figuring out a cheap and clean way to produce massive amounts of electricity - and then releasing it so that ANYONE could do it. Part of the conflict comes from the fact that fuel/electricity is probably the most profitable industry out there - but if you're not taking away their profits for your own use (just depriving them of a significant portion directly,) they've already lost half of the fight...
