Soil-free agriculture | Yuichi Mori | TEDxTokyo

This talk was given at a local TEDx event, produced independently of the TED Conferences.
Yuichi Mori talks about the world’s first agricultural technology based on a hydrogel film, created to address some of the serious issues that many communities in the world are struggling with, regarding food shortage, water scarcity and soil contamination.

2015/7/8 日テレの『笑ってこらえて』を観て感動しました。 森先生の発明は、地球温暖化に伴う干ばつや、人口増加に伴う食糧不足など・・・ 将来の人類の存続の危機回避に、必ずや貢献する偉業だと思います！ 個人的意見ですが、ノーベル賞に値する発明だと思います。

water, sunlight, air, and most importantly innovation. what a great job

森有一博士のような方がいること、研究に本当に感謝します。すばらしいですね。

What is great about this set up is that the plants that grow on top of the sheet are completely separated from the ground and its condition does not affect the plants (although I’d think some sorts of radiation will still penetrate). So it works even when the soil is otherwise considered unfit for normal way of agriculture.

すごいっ。人類に貢献していく技術ですね。

奇跡のリンゴの木村さんも凄いですが、この動画も世界から飢餓を根絶できるかもしれません。素晴らしい日本人。

土、植物、水、自然と人の関わり方に対するメッセージを感じます。

.In real-life application, you first cover the ground with a sheet (black in the clip) that is study and not penetrable. Then you lay a web of tubes on top that slowly disperses liquid fertilizer. This is then covered by a sheet of felt so the liquid fertilizer spreads evenly. Now you put on this magic film and then plant seeds on top of it.

I might try to add subtitles, but for now, here’s the gist of the story. ----- Dr. Mori developed a saran-wrap-lookalike film which could revolutionalize agriculture. It is made of hydrogel, the ultra-absorbing material used in diapers. He carefully calibrated the size of the holes in it; it lets water and nutrients go through but not bacterias or viruses because they are bigger in size

[@GenuineMind]

This means you can grow plants this way in the regions that were hit by the 3/11 disaster in Japan, even if the ground contains debris, was soaked in salt water by tsunami, or has harmful bacteria. They have successfully executed this method in Oman and also in space.

素晴らしい技術 できれば従来の水耕栽培との違いも知りたかった

[@litoboy5]

amazing

Est es technorogia japones,maravilla.

すばらしい。

Why there is no translate subtitle? It.s important if all important information from Sensei able to understand with broad spectrum

[@minasugimoto2821]

ブラジル🇧🇷でも、買えますか？

Where does the plant get its minerals?
