Please do not quoteNow, widescale home indoor farming isn't practical. Humanity needs to change that. Many reasons: economics, hunger, climate, etc.
"Possible?" Yes, economical/practical? Not now. Technically hydroponics exist, but aren't affordable/available, and operable by most.
Goals/impediments to actually making it real/feeding people with indoor/at home vertical or hydroponic farming:Materials: Easy recycling plastic would help (water/milk gallon jugs or 3D printing), failing that, something cheap/affordable. Unsure what.
Space/Land: Vertical gardening, but this relies upon materials and engineering/operations knowledge, that ... most don't have.
Climate: Location. Soil quality/artificial plant nutrient supplementation. Temperature, seasons if outdoor. Daylight if through windows...
Electricity/Light: Natural sunlight would require design (greenhouse, architecture). Better solar panels/wind would help. Otherwise....
Labor/Time: See above; lack of skills. Time may potentially be offset by resources, but depends on lots of things. Many unknowns.
Risk: A certain number of plants may simply not take. Bad harvests happen. Not insurmountable, or inconsiderable. Just be aware.
Pests: See "Risk." Sealing everything up reduces this greatly, possibly to 0, but that costs money. What do you do if they show up?
Water: Different methods require different amounts of water. Depending on water availability, may be more or less of an issue.
Social: Even if you get past the economic, material, electric, climate, labor, risk, etc. concerns. Would people want to do it?
Logically, it seems obvious, at first. There are hungry people. Grow more food, or do something. Alternative is malnutrition?
Realistically, we don't have the widespread tech. It shouldn't be impossible but there is a lot standing in the way.
How the hell is Musk or anyone going to Mars if we can't realistically grow indoors on earth? Earth's atmosphere/air works. Mars...?
Maybe somebody has a plan, and I hope so, but I'm not seeing it so far and nobody's showing it.
Proof of concept (not necessarily practical and unfortunately not presently practical really, but ...) : ] Container garden shelf with grow light. A more "high tech" Smartphone enabled routehttps://torontolife.com/shopping/six-indoor-hydroponic-gardens-for-growing-your-own-fruits-and-veggies/ Technically possible and at scale but the enormous price tag puts this right out of reach. If you really want to see scale possibilities but that's commercial and technically possible but incredibly expensive.Basically, I think humanity needs this and I hope we develop it, but we haven't yet. Not affordable or practical. Should it be: yes. Is it: no, not now.
Ideally: There could be a wall of hydroponic vegetables growing in PVC pipes mounted on interior home walls (or fancier setups) with windows letting sun in. Rainwater, and food/plant scraps (or even better
aquaponics for fish too) for fertilizer/plan nutrients. Solar or renewable energy would run pumps/artificial grow lights. The idea would be a home that sustained its occupants by providing food, electricity, etc.
Reality: We are nowhere near this practically at scale in an economical fashion. We need to be. We probably could be if we invested the R&D to actually do it, but .... We aren't.
As food prices rise, the demand (willingness and ability to pay) for this will too. They're not making more land.... There are a lot more people. There's a growing market, but it's mostly at hobby scale for home use, unless you count the commercial sector which is still quite small overall. In a better world than the one we live in, it could almost be an installed utility like a furnace or a hot water heater that produces food and plants instead of heat. Associated repair/maintenance professionals (HVAC/heating repair) could exist if the cost could be made practical. If someone makes this actually affordable then they could be a billionaire.
Sadly, it's now mostly a dream.
Does that mean it's impossible and that supplementation can't be done? No.
There are some alternatives on small scale Again, we aren't where we would need to be for even this to be widespread, practical, adopted/implemented. And even with several containers like this, you're likely looking at dietary supplementation rather than full sufficiency right now. That needs to change, but until then, you could easily argue something would be better than nothing. Somebody out there needs to figure this out, because if somebody can sell Americans a system that would produce food indoors economically comparable to what the grocery store charges (increasingly expensive it seems), then that person would become insanely rich.
Similar vein Agrovoltaics
https://en.wikipedia.org/wiki/Agrivoltaics Uses land, grows crops under solar panels. Let's give something nice to the rural people who can grow food AND power on their land. The power generated would be a cash crop. Someone come up with a modular unit where you put something like this on a 10ft by 10ft section of your lawn.... or whatever. Make a modular greenhouse like plastic sheet (recycled plastic if possible but whatever) that would cover this 10 x 10 unit to keep the birds from eating what you plant. That and/or make a smaller version that can be moved on wheels to move it into or out of the sun. There's another billion dollar idea.
Honestly, is there a youtube channel where somebody has documented trying this and making it really work? There's a content creation angle for somebody. Where's the guy or girl who is a youtube star for making dinner happen from this? I bet you people would watch if it existed.
Could the government do something about this: Yes. Will it...? I'm guessing no.
There could be more R&D dollars and effort put into these technologies. But.... "Spending is bad." It's investing but ok....
Could the economic aspects be dealt with if the technology was dealt with: Yes. Will it.... That's harder.
Ancient Athens once gave interest free loans to establish olive groves and other enterprises (businesses).
Seems like the major beneficiaries of this kind of government thing today are billionaires, so even if you're a normal business: No luck for you.
And if you're the average person.... It would be possible for large scale investment from government at no or low interest loans. But they won't.
Imagine we have someone put in a little home setup like this able to feed themselves and produce power. Veterans perhaps?
Pros/Benefits (assuming tech existed practically): Self sufficiency/saving on social support costs, environmentalism, asset creation.
Cons/Detriments (assuming tech existed practically: Upfront investment cost, politically unpopular that "Someone else" get anything.
My worthless personal take, it would be worth it. For now, it's not a reality. Could it be? Yes. Will it be...? Unlikely, absent large scale change.
