Points for mentioning one of the few videos that actually work out the cost of growing things without the sun -<p><a href="https://blogs.cornell.edu/hort/2014/02/15/seminar-video-skyscraper-farms-and-abandoned-warehouses/" rel="nofollow">https://blogs.cornell.edu/hort/2014/02/15/seminar-video-skys...</a><p>The largest human made solar collectors in the world are agricultural fields and clear glasshouses.
It is always good to have backup plans, even if they aren't practical now, they might do in a pinch. (Or in extreme environments). It is amazing that food and fuel are as cheap as they are right now. All sorts of things can go wrong on a global scale, it has happened more than once before. The best way to have a backup is one that has already been tested, even if its on a small scale.<p>Thanks for posting this. I'm done with having my examples picked apart, so I'm not going to do it with him. The fact is that it's less crazy than it used to be, which is a good trend.<p>I subscribe to many channels like this on youtube, and sometimes interesting things show up years later. I expect at some point I'll need to weld 2 incompatible things together, but by then the folks at "Impulse Manufacturing Laboratory at Ohio State" will have figured out how to do it, for example.
Whenever I read about container/underground growing with LEDs, I can't help but think of someone growing weed in their closet during college and thinking "how can I legally make money off this niche skill?"
There are hundreds of millions of acres of food production in the USA and we are to move it to Boring Company tunnels...?<p>Edit; I guess the video says most countries, but this idea still seems ridiculous for so many reasons.
I don't understand why? Build above ground solar grids and LED lights to transfer the light underground... For what purpose? The light is on the surface...
Having looked at the cost of growing crops with LEDs in containers... Its not cheap. The cost of the tunnels is also not cheap. Whilst we might survive underground we will also need people underground, industry underground...
