I don't know, I still don't get those things.. There's enough vacant land in that picture that if you planted up 50% of that vacant land with high intensity growing at ground level you would produce the same amount of food without having to build a giant glass dome with rotating internals.

Why is it that we always assume that a more high tech approach will be a solution to things like food production. The levels of embodied energy going into producing something like that, along with the constant energy costs of having all the internal plant growing areas rotating, are never going to offset the food produced..

The concept drawing seems to have a DNA helix type "extensive internal conveyor belt-style system to move potted plants from seeding, growing and harvesting stations"

But how the hell do they actually get the harvested, empty grow space back down to the bottom again...

And even if the desgin allows for that... what 50% of the grow area remains empty until it gets to the bottom????

I don't get it... and I certainly don't get the supposed environmental benefits...

And Hoeve... you guys are the masters of greenhouse design and hydroponic growing... how come in all the long years of dedicated research and development... the Dutch have never seen, or had the foresight.. to develop a model like this...????
