There is more than one kind, but yes. They are ~80% "Bio-oil". More oil
than any other plant. And they grow like an aggressive virus in a
susceptible sick host.
Basically there is about a 5-7 month ramp up. By the time you harvest
all of the area, you should probably should have started 6 months ago.
We are talking an HUGE up-front cost... and lots of lobbying from Big
Oil and conservationists and so on. If big oil were to realize the
payback and how quickly it would work. The conservationist should have
bigger fish to fry, but they won't.
