Hi Folks - as many of you have pointed out, I made a mistake when I said that Ultraviolet lights are used in vertical farms. In fact, it is not ultraviolet light - that would burn the plant. It's a mix of red and blue light, which is the part of the light spectrum that the plant absorbs. My apologies for this error.

This is why the light emitting diodes used to provide light for these plants do not include the green wavelength.

I was obsessed with the idea of vertical farming a few years back. There are some serious benefits ranging from land use, localised production leading to decreased transportation and packaging requirements, the efficiency of water and nutrient consumption, the lack of need for spreading pesticides and herbicides out in the wild effecting all the ecosystems surrounding farming (although i will say that pesticides do still have their place in indoor horticulture sometimes because of the lack of natural predators for things like aphids, white fly, spider mite etc) But the energy use is the real kicker. Hydroponic LED lights use specific wavelengths used for photosynthesis, mostly red and blue, which makes them about as efficient as you could possibly get for the purpose and yet you still need about 300 watts per square metre. Lettuce in a greenhouse can be grown using 250kWh/year/square m but for hydroponics that's more like 2,000kWh/year/square metre just from the lights assuming an 18 hour photoperiod is used (that's part of how you get such high yields with hydroponics) So once you factor in climate control etc it's probably about 10x as power hungry as a greenhouse per square metre and if you used natural gas power for this at 400gCO2eq/kWh then that's 800kgCO2/square metre/year This is why alternative energy is so god damn important but for the time being we already have to electrify transportation, heating, cooling, industry etc etc and we're only about 11% electrified. Adding another huge power hog onto the grid to do a job that the sun was already doing is nuts. All the extra clean energy we can get our hands on is already needed to displace fossil fuels. One day... Maybe... We might have enough nuclear to get that 800kgCO2/square metre/year down to 24kgCO2/square metre and then it might be worth it. But we aint there yet

Insects would lay eggs in the rotting food scraps, but the larva would tend to fall betwwen the screen's mesh into the water as fish food. The fish water would be taken from the bottom of the tank, circulated to the plant roots and also to a ping pong ball filled clear chamber in which algae would grow on the balls surfaces (not sure which got the water first, the plants or the algae, the algae was to remove any excess ammonia), last step was a spray of water onto a plastic wall, down pebbles. Counting you dining table, it was meant as a near closed loop system.

We love the idea of vertical farming, for a variety of reasons, but we have some questions about the nutritional value of plants grown with only the bare essentials of their required nutrients. What about the many trace elements and organic compounds that are typically found in healthy soils and get taken up by growing plants? Also, what about the many complex plant exudates that are excreted by diverse plant communities thru their roots and are made available by water transport to neighboring plants? Will vertical farming create edible crops that look healthy (buffed in fact) but will be lacking in all sorts of micronutrients, plant hormones & trace mineral compounds that might be necessary, in the long-term, for robust human health? (The reason that these questions might be important is because science & technology have been largely co-opted by business & finance, and not telling the whole story of products & services that are for sale has become the norm in sales & marketing. In the 21st century many things high tech are "cool" right up until we find out that they weren't and now there's a class action settlement of some sort. "Round Up Ready" comes to mind almost immediately as a cautionary tale of an FDA-approved high tech farming solution that turned out to cause cancer, remain persistent in animal manures, and, eventually, make their way into living human cells. Being in high tech my whole adult life, I have learned by experience to be cautious & suspicious.)

When Epcot Center (Disney World) opened in 1982 I made a visit. One of the displays they had was a system of growing tomatoes where the plants were suspended in air and their roots were periodically sprayed with nutrient rich water. The yields were very high. They were growing in a greenhouse so they were using natural light. But artificial light would do the job as well. Plus temperatures can be controlled to maximize flavor. Tomatoes seem to need some heat to encourage the chemical reaction that boosts their flavor but if the temperature gets too hot the plant ceases forming fruit. You've probably had first hand experience with the "too cool" lack of flavor from tomatoes grown in greenhouses in the winter.

One way to lower the electrical consumption could be the use of daylight harvesting/solar harvesting in a hybrid set up. Whereby natural daylight is brought in through a series of mirrors or fibre optic cables. Used next to the growth lights so they don't have to be fully turned on all the time (only night time/ rainy days). I reckon the cost of the system might not make it worthwhile to grow the crops but the technology has been there for a while. Perhaps when prices of such systems drop till a level which makes it possible for growers to still make their profit we may see such hybrid systems in place

You completely missed the bigger point against the need of vertical farming. The problem in most of the world is the "quality" of the farming done. I come from the Netherlands. We export more foodstuff than America does on a fraction of its size. We can do this, because for more than half a century we have already been using hydroponics in green houses. We already have vertical farming in widespread use. (www.meteorsystems.nl/en/growing-systems). Though not as high density as your examples as there is no need for that. Our water management even on "normal" farms is second to none. When looking at other countries. You get the situation that the water used for 1 crop of Egyptian tomato's can do a year of many crops in our greenhouses. Even most American farms are old fashioned by our standards. When Americans want more crops, like many out there, they just take more land, use more water. Simply because it's easy. We are a small country and had to feed our selves. So we needed advanced farming solutions that use little water and no pesticides and other bad things. Now we feed the world. If everyone farmed as the Dutch do now. The problem of feeding the world is gone. We would have severe overproduction and no need for vertical farms. That said, there could be some use to them in city area's to keep distribution lines short. Flying food all over the world also has an environmental impact. And with climate change reducing the water and pesticide use even further down is a good thing. But as I said, the technique is not a problem, we have been able to do this for years. The problem is getting countries and their farmers to accept this new model of growing food. If governments don't incentivize moving to new techniques by making strict environmental rules, its not going to happen. Simple rules like banning pesticides. Subsidizing greenhouses over traditional farming. Increase water cost for industrial use. (if your Spain, ban illegal water wells and make an effort to police that).

Oh, vertical farming! This is one of my favorite subjects, because it's a necessity if humans are ever going to live in space. And it's also a natural extension of the idea of agriculture. Thousands of years ago the first proto-farmers discovered they could get more edible plants if they took control of seeding and watering them, instead of letting nature do all the work. Vertical farming today is taking control of everything else and removing all the randomness of nature from agriculture. It's an extremely human thing to do. But there are problems, and you pointed them out really well in the video. The biggest problem is trying to replace the sun with artificial light. The sun shines for free, so it's always going to be difficult to beat that with electrical power. Of course the idea is to maximize the advantages of vertical farming (water and land conservation, no diseases, pests or destructive weather and the ability to push agriculture to its theoretical maximum of production) to the point where it becomes cost competitive with growing plants outside. We're not quite there yet, but as you said the engineers are finding greater mechanical and electrical efficiencies all the time, particularly with the technology of LEDs, so it's possible that point might be reached in the near future, _especially_ when teamed up with renewable energy sources. But right now the biggest problem with vertical farming is what they're actually growing in those food factories, and you pointed this out as well. The vast majority of real world agriculture is devoted to cereal crops, with leafy greens just a subset of the subset of vegetables. To truly change the world and eliminate food security, we'd need to invest in vertical farming the same way we invest in computers or automobiles today, pouring hundreds of billions of dollars into building the infrastructure and then devoting it to crops that aren't that profitable. In my own country I can tell you that (pre-pandemic) wheat wasn't that profitable. Farmers were already turning away from it in favor of other crops like barley and canola. It's really hard to imagine how a vertical farming industry could make a profit if they had to compete with that. But the future is bright when it comes to vegetables and fruit. Fruit in particular is vulnerable to weather damage, so it could be a potential area of expansion for vertical farming if they can figure out the challenges of growing bushes and trees in a vertical environment. At the moment vegetables are the easy target for expansion, and that's probably what the researchers will focus on next. Anyway, thanks for the video! (Sorry, I should have said that first.) This is a fascinating topic that I think will become more and more important as the years go by.

One thing that is too often left out in the discussion of combatting climate change is examining how we allow our urban environments to grow. Instead of continuing to allow massive sprawl, we should look to eliminate euclidean single-family zoning and parking minimums as well as enacting urban growth boundaries. This will allow us to upzone our cities, creating better density and therefore more effective transit systems, and it’ll wean us off of car dependency. We’ll also be able to have farms closer to our urban environments, requiring less transportation, and it’s not even reliant on not-yet-fully-actualized technology.

There is a huge issue with vertical farming that makes it a non viable option. You have to look at calorie production. These farms are being used to produce very calorie-empty foods (leafy greens), at the cost of a huge amount of energy going into the system. Growing fruits and vegetables is what they need to be doing to have any hopes of this being an actual solution and not just an elitist jerk-off fest where people see how much money they can spend to 'save the world'. The further you get from nature, the harder and more wasteful things get.

But even that is like 90% less water than what we currently use. Other than that the only thing it requires is a whole lot of power. Now if that comes from fossil fuels, than yes, it's going to be dirty. But fossil fuels are done, they are going away fast.

8:15 Excellent idea. On an earlier topic, I was thinking that similar synergies could be used in the renewable energy space by building molten salt thermal solar plants next to liquid air plants and utilising some of the heat for recondensing the steam for expanding liquid air and driving the turbines. Once the steam has been produced by the turbine from the molten salt and driven the turbine, the steam could then be recondensed by passing it through a heat exchanger in the liquid air plant, in turn driving the liquid air expansion process. Once the superheated steam was cooled back to close to below 100C, the water would flow back to the solar thermal plant turbine, ready to be re-heated by the molten salt at 500+C. This would be an ongoing mutually symbiotic process, since the inefficiencies of both molten salt and liquid air both arise from the recooling for molten salt and reheating for liquid air processes. In the event that more than enough renewable energy (from local wind or local solar PV) was being produced, this could be stored in both liquid air form and/or heat capacitors for molten salt, again acting as a battery or energy storage device. The two would be balanced constantly by an algorithm, so that there was always enough heat to regas the liquid air and drive the steam turbine, and always enough liquid air stored ready to condense the steam turbine's steam back into water. So you would always have additional molten salt capacitors and liquid air vessels, which would fill and empty depending on demand. If there was low demand, then solar PV and/or wind would continue to make liquified air and store it, and thermal solar would continue to heat molten salt in heat capacitors and store that in storage tanks. In the event that energy was demanded, then stored molten salt would be brought into play at driving turbines and heating liquid air. During the day, solar PV would drive liquid air collection and solar PV would drive molten salt collection in heat capacitors (as well as generating any electricity needed during the day.) At night, when both solar PV and solar thermal closed down, molten salt from the capacitors would be released into the system to continue to drive steam turbines and heat liquid air to drive liquid air turbines. This means 24/7 production of electricity. Probably best suited for sunny climates that supports solar thermal, although you could do the same with wind, but less efficiently since you'd need to use the wind energy to heat the salt electrically (similarly to how liquid metal batteries are heated I would guess.)

@@pietersteenkamp5241 My dad was involved with a British climate change science team way back when I was a schoolkid (over 40 years ago). His job was to create computer programs to measure scientific data, thus allowing the 'experts' to make the necessary predictions. Although climate change science wasn't his particular field, he was interested in what these scientists were doing and asked them if there really was something to be concerned about. The answer was yes. They then gave him a list of expected effects and roughly when they would occur. Once this contract was completed and he returned home, he told me what these scientists had said would happen over the decades - and they have proved right in every single instance. The problem with the media is they are always after ratings first - truth second. If that means getting their story from a less reliable source or quoting people out of context, they are quite prepared to do so (I know only too well what it's like to be quoted out of context in a national paper, it nearly cost me very, very dearly.

I think that focusing on fruit, vegetables and greens, as well as herbs, spices and medicinal plants for urban farming is a better priority. Grain is a concentrated dry seed grown on a big stalk, so most of the plant isn't edible, growing wheat in a city means figuring out what to do with all the hulls and straw, whereas lettuce, carrots, radishes, apples, you just pluck them off a plant and walk them to the shelf at the farmer's market, minimal processing and waste. Grain is the most shippable food in the world, it's dry, keeps well at room temperature and you can handle it with a shovel and not damage it. Since it's dry, you aren't effectively shipping tons of clean drinking water from the place where it's grown to the city either. If you have water reclamation as part of your city's sewage system, the water used to grow an urban strawberry can stay in circulation within that city instead of being shipped half a continent away. TLDR, grain is already the most efficient food to transport so it should be a low priority for reducing that shipping distance, there's more benefit to be had changing the way we get more perishable and delicate crops. Besides, the reason grain accounts for so much of our diet is a consequence of it being so portable and storable, who's to say that grain's share of the demand wouldn't drop off a lot if we could get access to better calories year-round close to home.

I have grown vegetables hydroponically for over 50 years. It works, but it's not all a bed of roses. There are several problems as there are with soil farming, just not the same ones. For anybody starting out, the simplest and most productive system is the Kratky system developed by dr. Bernard Kratky of the University of Hawaii.

Only some plants can handle 24/7 light. Many plants need off time to rest. Some plants rely on light times to determine when to fruit. Something to keep in mind when you try growing plants at home, indoors for food.

Although vertical farming may be technologically efficient the end product is food made without soil, but also soul. Humans developed in equilibrium with soil, bacteria, fungi, viruses etc. Regenerative farming has shown the way to produce food with maximized nutrient density; which is said to be essential to produce healthy human beings. Having said this may I applaud you for producing such interesting and well presented videos.

Definitely one of the most interesting techniques for food production, can't wait to see how it will improve. Not sure how feasible it will be for a massive population, but it will definitely pave the way to the whole localized way of supplying our basic needs we will be presented with in the future (energy/food production f.e.). Great work as always!

you can have 100x Yield in a Rail Car or Shipping Container , than a Backyard Garden.

I've tried aquaponics in a limited domestic setting, with ornamental fish while growing herbs and greens on damp gravel beds. The green yields are impressive, but my fish aren't destined for the table. Anybody looking into a small setup should accept that the output if majority vegetable, with the bonus of a few fish now and again.

3 dimension aquaculture in a shipping container based greenhouse is particularly intreging to me. This is mainly because your growing more than one valuable resource locally. You also get a climate controlled year round environment growing and it's a technologically supported organic ecosystem.

@@markplott4820 I know, that's the idea! You can maneuver aquaculture based hydroponics to work in a shipping container. It's a shipping container and a veg garden.

We could also have floating multistories high griw houses on the sea, using sunlight to condensate, as well as other types of desalination using wave power

I got late to this video but my wife and me we do aquaponics at home and we run a led light that is on 8h a day and it cost 20$ a year to run it. We get a lot of our herbs out of it as well as greens. We are planning to expand and get tomatoes and things like that

Thank you for including Aquaponics, I think it has a lot of potential. Their are lots of people doing DIY projects of this. And also students in the US. When we are on the topic of local production, maybe check out the old: Sahara Forest Project
