vue - Why Vertical Farming Won't Save the Planet

1. This guy has no idea what indoor farming is about. He has a good point regarding the electricity needed for lights the rest of his talk shows that he doesn't understand that crops grown by these methods grow 3 times as fast and so produce much more in the time, the water is REUSED again and again that is how it is saved and that has nothing to do with where it comes from originally. Of course it will come from the grid. Fertilizer is organic and usually comes from fish which are grown at the same time and add a crop to the system. There is no cost for fertilizer at all and it is renewable and sustainable in the systems that are being used. Seems this guy just wanted to make a big list of the reasons it won't work. It is working and will continue to work in more and more efficient ways.
2. i SAW ON A RECENT DEPICTION THAT THEY PROPOSE TO GRAZE CATTLE UP IN THESE HIDEOUS BUILDINGS ALSO; HEAVEN FORBID :(
3. Vertical Farming are good... for deep space structures, maybe.
4. Far too long winded, but the man does have a point. These vertical farms are set up as huge industrial complexes, and they make claims that no one can confirm as they get no actual insight into what they consume, but at the very least we are talking factory levels of electricity with highly labour intensive daily management.
   This sure as hell will not be usable anywhere but the richest parts of the world, parts where food is already being thrown away due to excess of everything.
5. If we had any chance of colonizing mars, it would be through the implementation of vertical farming. Just think about it... It is a paradigm shift. Where you have inefficiency is in energy production. Vertical Farming abstracts the farmer of needing space and land. Which has more footprint? We need to just solve the problem of energy production. I liked professor Bugbee's point that to have a vertical farm you still have to sacrifice a lot of land in order to obtain solar energy. Yet, the approach of vertical farming is simply more efficient: No need for pesticides with vertical farming! Sorry doctor Bruce but Aerofarm is KILLING IT
6. Vertical farming isn't a single solution to resolve the problem of population and food resources. It is a specific niche based approach to producing food in areas where renewable energy is the primary energy source (think Iceland), that typically don't have access to food production and typically import food.
   
   The title of the video is correct but it also doesn't make sense because I don't believe anyone is calling for a total shift to vertical farming. It is simply one of many solutions.
   
   Another niche based solution is Food forest gardening in the suburbs, where people build a small personal food system for themselves meeting some of their dietary needs from outside of their back door.
   
   Beyond the suburbs you move into integrated farming systems, like Sepp Holtzer's farm, and then maintain the industrial food system to make up the difference.
   
   The idea that any one system will solve the problem is ridiculous, because it isn't a simple problem. But the problem is the solution, and in the case of available farming land being on the decline, vertical farming does resolve that issue in a specific use case.
7. Vertical Farming is ONLY an ALTERNATIVE for people to grow food. It lessen the abuse on traditional farming using GMO's and forced Farming thru fertilizers.. It isnt effecient as traditional but it serves the purpose on feeding people without abusing mother earth directly.. Technology now contributes many facts like LED lights..
8. I like some of the others found the presentation could have been shorter. The biggest issue I have is that he keeps talking about photovoltaic panels. This is the least efficient way of capturing solar energy. I also think his vision is skewed against vertical farming for whatever reason. One of the biggest reasons for vertical farming is water reduction. I heard no reasonable arguments for traditional farming as opposed to vertical that held water.
9. name checks out
10. Mirrors, bro. We can use mirrors during the day time to provide solar energy for plants depending on the reflexive capabilities of the mirrors you're using. We can also use solar panels atop and on the sides of the building to maintain energy for the night, and panels on the E/W to get maximum input.
11. 3:42 "he was terminated" lol
12. It is a long lecture. A15% efficiency in for photovoltaic solar panels sounds about right, but will the efficiency and the cost of solar energy improve in the foreseeable future? Also, solar panels could be built on irrigable/undevelopable land, where other usages of the land are limited. The production of CO2 could decline in the near future as electric transportation technology becomes viable.
13. I am not an agricultural scientist (I am an engineer/attorney) but thinking about investing in hydroponics. After watching this presentation I have some concerns about the potential bias of Professor Bugbee. My first impression was that he exhibits all the signs and verbal cues of a witness that is being less than truthful on the stand. For example: at the end he made comparisons of soil growing using the "best" for high value crops as the comparison to the worst in vertical farming.
    
    His claim about conventional soil water lose seems at best disingenuous, because reaching 95% efficiency in conventional farming is rarely done and would be extremely labor intensive. Also his initial "math" analysis appears to use the full spectrum of solar radiation from the sun, while plants use only a small portion around 450 and 600 nm. LED lights can be constructed to emit in these narrow bands and therefore are very efficient.
    
    Logan UT, where Utah State is located, is a primarily agriculture based economy, I wonder if there is an undisclosed agenda at play here. Finally, It would be nice to have a realistic comparison of conventional verses vertical hydroponic farming, instead of this apples to oranges comparison.
14. this guy is a professor? Bruce has clearly missed the new technology replacing the book he was waving around. what a tool. His next video will probably be how solar panels wont work and they offer no value. Sorry if you paid to watch this ghastly lecture.
15. but what percent of the sun light is needed for plant growth compared to specific wavelengths used by LED's?
16. Boo.... Their are so many forms of vertical growing that are extremely efficient, even vertical growers are moving away from this skyscraper model!
17. to long video, in 10 minutes you could tell the same message.
18. Yeah but can't you use lights that emit only in the spectrum that plants like to utilise the solar energy more effectively?
19. the market will decide
