| 00:00 | the subject of the final installment in our trio of truly tiny things is also measured in nanometers it's not a microbe or a machine it's just a little air bubble you might be asking other than spritzing up a champagne what possible use could we have for nano bubbles well let's find out here eight meters under the sea we found something out of the ordinary what looks like white liquid is actually seawater that contains small air bubbles which in turn produce even smaller bubbles these so-called nano bubbles are the focus of |
| 00:36 | a lot of attention as they are part of a new system that can help restore aquatic life to a healthier state let's see how the nano bubbles are produced in a small water tank a jet of water is coming out from the pump on the left once it's plunged into the water this small nozzle produces micron sized bubbles that further shrink as they travel through the water turning into nano bubbles using a microscope let's take a closer look at how the bubbles shrink down to nano size after a few minutes the bubbles have gone from tens of microns |
| 01:16 | to tens of nanometers this is the carbon ceramic nozzle we saw earlier the porous nature of the ceramic allows air to flow through apparently it was impossible to produce animals with non-carbon-based ceramic this system was developed not by a major company but rather by a small factory run by ins I hunted their original technology has baffled many experts there already existed several types of nano bubble systems but all were complex and very costly it wasn't too surprising that researchers were skeptical when they were first told that |
| 01:58 | nano bubbles could be produced simply by sending air through a small ceramic nozzle they never imagined it can be so easy but demonstrations show that nano bubbles remained in the water after the nozzle was taken out the bubbles which normally can't be seen with the naked eye reflect light as they pass through a laser a regular bubbles normally disappear quickly but nano bubbles last for a long time which is why they were detected by the laser the researchers were convinced and anxiety on sensors discovery was put under the spotlight |
| 02:38 | according to developers Satoshi enzyme their invention was the product of chance I took smacking oh dr. Soto danger Oh disaster my states on average yes I open-source a side project on the Nautilus I also sent a mini a norm todo missing Honda's waha totally no ceramic so Sebastopol ceramics is nano bubbles make my own his own you wanna go to hockey semester the bio knew karate katoa Mosca saleh Eamon de Valera Khatta meetha schmatta head rotary masculine high scope authority given tonight you have so little is from a stair the |
| 03:24 | nozzle can be easily made in a multitude of sizes and shapes this is particularly useful for adapting the technology for large scale applications such as the diffusion of nano bubbles at the bottom of the sea Pablo has a so jealous what a house ricotta universe machine is walking our kites to car honking ah I said there a hustle sudeerneer tyree Oh No Oh sky still not dismiss and awoken our energy used co2 snow Sunday a motorboat I think inevitably Sharda Thapa yoga concert a mean motor Delta te amo no hace una mezcla y ou are a no |
| 04:02 | ceramic Kuchiki no ma no Alice nay a Sachi hodo is old imitated I tell you he Tony G Sonakshi holiday our hostage super taught a class word Sao Paolo get see I got in 2011 an experiment was conducted at a seaside park near central Yokohama the effects of nano bombs were tested in the sea water beneath an egg dunk the device consisted of propeller shaped stirrups and a bubble defusing nozzle it was small enough to be carried by truck and can be easily moved without the need for complex heavy machinery device was installed in only half a day |
| 04:40 | with the work of three divers the machine was set up at the bottom 10 meters below the surface although the water looked quite clean from above the seabed was covered with about a meter thick layer of sludge the water was murky and there was very little sign of aquatic life so whatever our to you know it has a static or Okada swimming in Catalunya not this man deskah it's possible a Sunday no SoCo photo moon Alice so no boat a mini cookie o coup d'etat mean you are given no chikara the cheese in decimal I was there there's so much |
| 05:20 | Isandlwana kind union up the a header on its my context oh you waited a joke a solitary joka to amass kizuita save since also todo que Taggart on Youku dato a series of experiments took place in the sea near an aquarium also in Yokohama in 2013 this is a hundred square meter area near the mouth of Tokyo Bay with sludge piled up 50 centimeters thick at the bottom the nano bubble device was installed on the seabed eight meters below the surface with a long tube to supply air from above the system is very energy |
| 06:08 | efficient working on twenty-two hundred watt current the white jet of bubbles coming out of the nozzle turns into smaller bubbles that instead of going up are dispersed around the bottom samples collected in February contains sand worms and small clams two organisms commonly found in polluted waters but in July there were fewer shellfish and some species of small shrimp were found in larger numbers arthropods like shrimp cannot survive in environments that are poor in oxygen in half a year the system had begun to show positive results at the |
| 06:53 | end of the experiment in January 2014 the aquatic life of the area had significantly changed various types of fish were observed near the reef and seaweed had grown around the device the sludges thickness hadn't changed but its content was different its surface had become coarse like a sponge and various organisms were found living inside the nano bubbles had changed the ecosystem near the seabed Thank You Altiris karna Stano each could the others lay oh she had soon or Okara juvett una de Manila seems casa minha |
| 07:34 | una geo tiny Cochiti know again joyously whatever I know dusted cometo you are at a terminal and sua sono disables no sekai daddy so Tony you go there too you know show me the key Reba whatever it is indeed more she then no naka de The Kills on stage ticketed shall dine are they giving you like a tortoise bubbles that shrink and remain underwater for a long time nano bubble technology is quite intriguing the company's original and simple ceramic nozzle system can be adapted to a variety of situations and there are plenty of sea regions around |
| 08:10 | the world that can benefit from their invention which can help bring back abundance and diversity to aquatic life across the globe this simple little piece of ceramic could end up having a big impact on our oceans as scientists learn more about the complex dynamics of climate change declining oxygen levels and sea water are becoming more of concern nano bubbles might be one way to blow some life back into the world's largest ecosystem that's all for today thanks for joining us tune in again next time when we'll introduce you |
| 08:42 | to even more great gear until then I'm Matthew Masato Barron do |
