Ah..Soylent Green. If they can hook up with G-Oil rendering plants ..we could be on to something.
No, seriously, I hope that this proves to be a decent "net gain" enterprise. It's extremely hard to "manufacture" energy cheaply.
Now just produce 20M barrels a day of it ..there's enough ocean, I guess ..but what do you have to do to it to get that level of yield. What other life form is going to step aside to enable this?
Looks like China is way ahead of us.
