I guess in that future we're getting power mainly from renewables and using hydrocarbons as power storage? We'd probably be using those same hydrocarbons to make plastics and the like as well.
Still, halting new fossil fuel extraction would be an excellent first step, even though the energy costs don't make much sense to me.
But I'm not clear on wether their price point includes the revenue they get from selling the carbon (in the form of fuels or plastic)?
I.e, does it cost them 36 USD, or 351 USD? [0]
[0]: 36 USD + (1 tonne of Co2 / 19 lbs of Co2 per gallon of fuel) * 3 USD / gallon of fuel ≈ 36 + 105*3 = 351 USD. Makes a huge difference...
That's so much better than what I could have thought!
Even though my skeptical self almost falls in the "too god to be true" category I see you mention on Twitter, I'm very excited about following Prometheus' progress :-)
BTW: Make sure to let people know when/if human-drinkable ethanol "fuels" from Co2 are available for order! ;-)
