That's fab. I like too, that it's two local companies doing it together, bypassing feeding the megacorporation of Xcel (I presume Xcel since Denver) and buying CO2 from them (and who knows what their source is].
We really need more local interdependence and less reliance on megacorps if we're going to survive, let alone change the world.
I mean, I'm sure for both companies it was a great PR move, but hey, whatever pushes things in the right direction!
