砂を液状に…カヌーもこげちゃう? 流動床、応用に期待

角拓哉 2017年5月16日08時50分

砂を液状にするという、ものつくり大学(埼玉県行田市非常勤講師の的場やすしさん(53)と、同大教授の菅谷諭さん(56)の研究が関心を集めている。砂の中に空気を送り込み、液体のような状態にする「流動床(りゅうどうしょう)」と呼ばれるもので、アトラクションやトレーニング分野への応用が期待されている。

 流動床は、砂を入れた容器の底から空気を送る。砂にかかる重力と空気で浮かせる力が釣り合ったときに液体のような状態になる。

 研究室では、縦1・7メートル、横1・1メートル、高さ60センチの大型水槽に1トンの砂を入れて送風。手をいれれば水の中と同じような感触に変わり、底に沈めたボールも浮かび出る状態になった。川下りの映像を見る「ヘッド・マウント・ディスプレー」を頭部に装着し、船に見立てた小さな水槽も浮かびあがり、カヌーの疑似体験もできた。

What the fuck is happening

To all those who are wondering, while I don’t speak the language I do understand the science behind this video.
Basically what is happening is they’re blowing a bunch of tiny bubbles into the dry sand, what this does is make all the particles move around each other actively making the sand act as a fluid.
So while the sand is aerated you can easily move things around in it, but when it’s not, it settles and returns to a more solid mass.
It’s the same idea of how real life quick sand works, just substituting water for air.

what the fuck. what the fuck how. how the hell.

“how the hell” is the fact that flight paths are ENTIRELY PRE-PROGRAMMED AND SCHEDULED. This is trivial.

“Technology has gotten so precise that it is possible to sync the image on an enormous video screen with the movements of an actual, real life, giant flying machine carrying hundreds of human beings thousands of meters up into the air. This is trivial.”

It’s absolutely not trivial, because it means that a flight somehow took off when scheduled.

FARMBOT GENESIS: This robot is changing farming as we know it

And the best part about this technology is that it’s open source, meaning you can build one yourself from the blueprints that are available for anyone to download. 

Check out the full video to find out more about Farmbot Genesis.

This is so neat.

THE FUTURE IS NOW, PEOPLE

Does it…is it killing the weeds by STABBING THEM?
