Sorry to sorta necro this but I had a couple of his numbers floating in my head and I had to do the math.

He suggested that you could feed a city block with only 2 floors of a skyscraper which is already an insane ask but whatever.

But that means for a city like Philadelphia, you would need a total of around 16,000 buildings with 2 floors each dedicated to farming which widespreads your farmers. Or if you decide to dedicate each building to farming only you still need 322 skyscrapers each 100 floors high to feed the city.

Which means water pumps and infrastructure to support all that water for 322 buildings which is about the current number of high rises and skyscrapers in Philadelphia combined.

You need to convert your entire city to food production just to feed the city that is just existing to feed itself.

My God this really isn’t the win they think it is. Technology will certainly save us but man I don’t see it in the pie in the sky scifi answers but something boring like protein manipulation in yeast cultures.

Not surprised at all. Beyond that, I suspect even two floors is already too many to effectively power the thing with solar on the roof of the same building. Even converting solar to electricity to a narrow spectrum of light at 100% efficiency for the entire thing wouldn’t get you there.

Welcome to the discussion of US Politics!

Rules:

  1. Post only links to articles, Title must fairly describe link contents. If your title differs from the site’s, it should only be to add context or be more descriptive. Do not post entire articles in the body or in the comments.

Links must be to the original source, not an aggregator like Google Amp, MSN, or Yahoo.

Example:

  1. Articles must be relevant to politics. Links must be to quality and original content. Articles should be worth reading. Clickbait, stub articles, and rehosted or stolen content are not allowed. Check your source for Reliability and Bias here.
  2. Be civil, No violations of TOS. It’s OK to say the subject of an article is behaving like a (pejorative, pejorative). It’s NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
  3. No memes, trolling, or low-effort comments. Reposts, misinformation, off-topic, trolling, or offensive. Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to “Mom! He’s bugging me!” and “I’m not touching you!” Going forward, slapfights will result in removed comments and temp bans to cool off.
  4. Vote based on comment quality, not agreement. This community aims to foster discussion; please reward people for putting effort into articulating their viewpoint, even if you disagree with it.
  5. No hate speech, slurs, celebrating death, advocating violence, or abusive language. This will result in a ban. Usernames containing racist, or inappropriate slurs will be banned without warning

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

That’s all the rules!
