Welcome to the discussion of US Politics!
Rules:
- 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:
- 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.
- 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.
- 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.
- 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.
- 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!

No I know all about how incredibly efficient hydroponics can be and even deeply loved reading a research paper on using just nutrient enriched water for roots systems without the need for soil. Super cool stuff.
But still doesn't take into account electricity use is way more power than just using the sun. There is a reason greenhouses are standard still in that they are cheap and only require basic maintenance but still let you harvest the sun as an energy source.
But scaling that to feed an entire country is basically impossible. Power use becomes outrageous and you get limited by size. You need a skyscraper to feed a city and nearly as much energy.
It works on small scale and can be much more efficient than local wild growing for small scale productions but that's about it.
The math for how much energy we take from the sun and how much of it is absorbed by plants is not negligible. And it will not work for all crops in our current energy needs to run it. Especially with our current production rate and system.
Sorry but it's the truth. It's just not there and won't be for a while.
You really need to argue don't you?
This problem you are stuck on isn't actually a problem. Why? Because of how much more efficient it is. No one is saying that one vertical farm will feed the entire country. We will still have local farms, home gardens, etc. This is the future of growing food both produce now and meat in the coming decades.
Yes, the solar panels only convert like 18% of the incoming light, but, again, $ for $ growing things with solar and aero/hydro is way way cheaper than dirt, relying on the sun, seasons, etc.
Seriously. Maybe stop focusing on what you think is wrong and work to improve things.
Vertical farming is the only way we will feed people in the coming decades.
