What would be interesting to know is how much electrical energy it took to produce those lettuces in the Antarctic. Actually that equates to how many litres of distillate for the generators.
I believe your focus on energy requirements is not the most important issue here. The reason for that is that wind energy in Antarctica is off the charts high, as well as being nearly constant. They will always have plenty of energy to grow these veggies. The issue is whether this technique provides adequate nutrition for people and animals that will consume it. I am not convinced that it will.
One of the reasons I get tired of posting at the Doomstead Diner is your misguided fixation with energy issues. The problem is pollution, not energy. I will never convince you of that. That's regretable but I can deal with that as long as you stop using my channel to voice your erroneous world view that lack of energy instead of massive pollution from greenhouse gases is what will cause the collapse of human civilization. If your purpose is to "teach" me about what a "tough world" it is out there, you are wasting your time. I knew about that long before you did. If your purpose is to make me stop posting about the
sine qua non benefits to mankind of Renewable Energy, you are succeeding. Keep it up and I will stop posting completely. Congratulations, fossil fueler.
Boy oh Boy, That Eden Project certainly looks inviting.
What a gorgeous looking vegetation endowed spot on our marvelous planet. :emthup: :icon_sunny:
Yes, it is quite impressive. Did you see the large greenhouse in Iceland used for starting their tree saplings in the posted Iceland video? It wasn't that big but it wasn't small either. The Icelanders get it. Climate Change caused by greenhouse gases is THE issue of our time, not lack of energy.
For some really BIG greenhouses, though not in the attractive dome shape of the Eden Project, check out Denmark's massively huge greenhouses. I posted on it a while back. You can find it if you do a search.
