Good points jh, we have to be more sustainable and stop flying over the world for one. If we don’t reverse these trends quickly we might not be even able to live like the Armish.

Given that so many ways people earn their living/(economic activities) are bad, what are we going to do? It seems that only people like the Amish live well from generation to generation without disrupting the environment much. It also seems that the world population is far far too big:

Did you know that during the 20th century, human population multiplied from 1.6 billion to 6.1 billion people, and that heat trapping carbon-dioxide (CO2) emissions grew twelve fold? Sierra Club.

I’m not meaning to highjack the thread but introducing a reality check.

Depending on what they use for fuel for the ovens they COULD make this a lot more environmentally friendly. Nothing wrong with big!

I wonder about the economics though, and the business case is not clear to me… at all. How much cement do WE need, how much is for export… like Al, this is an “energy” export, less a water export.

Is there a case to be made that we can consume its product internally? That’s the question I’d have. Concrete is currently around $225/M3 delivered. It seems a bit expensive already… demand here is high enough to justify that.

Let me guess – we’re exporting the concrete to China?

This looks even more retrograde than re-starting a coal-fired power station in Whangarei. I can hear the evil chuckles of Muldoon’s ghost – even “Think Big” projects didn’t rampantly fly in the face of contemporary research like this does!
(although, maybe… Manapouri Dam was pretty universally loathed for a while, I recall… of course, I was only a toddler, so my recall ain’t that good )
