00:00Continuing the topic of child inventors, let's now look at ours.
00:04For example, in 2020, schoolchildren from the city of Tiumen set out to address the lack of speed bumps for
00:11cyclists.
00:12Reaching rather high speeds, they often cause injuries to pedestrians and even more serious accidents.
00:18The city has 60 kilometers of bike lanes.
00:22That's why the idea of 14-year-old Diana Martinkovich turned out to be very timely.
00:26The main feature of such a speed bump is that it's made of a non-Newtonian fluid.
00:32It sounds scientific, but anyone can make a similar fluid in their own kitchen.
00:36Just 4 kilograms of potato starch mixed with water and placed in a vacuum.
00:41And a speed bump for the bike path is ready.
00:44The viscosity of a non-Newtonian fluid depends on the speed of the impacting object.
00:49If a cyclist is riding slowly, the speed bump won't pose a serious obstacle.
00:54But if the cyclist decides to ride fast, such an obstacle will slow him down.
01:00Diana, along with her young colleagues, is also developing a smartphone app where locations for speed bumps will be marked
01:07on the bike lane map.
01:08The girl really hopes that the city authorities will approve the installation of her invention.
01:12After all, it does not require any major expenses.
01:15Her friend, often behind the inventions of people, including children, is a sincere desire to help a loved one.
01:21This is precisely what happened with schoolgirl Arina Filimonova from Nizhny Novgorod.
01:26Her close friend fell from a tree, injured his spine, and spent almost a year in bed.
01:32Arina had been interested in studying muscle stimulators for quite some time.
01:35Devices designed to stimulate the body's muscles.
01:38The accident with her friend compelled Arina to get serious about developing her device.
01:43And in 2020, she presented her project, a specialized suit equipped with sensors to track the patient's condition and stimulate
01:51the muscles.
01:52The suit is made of several layers of fabric that do not restrict movement.
01:57This kind of fabric is commonly used in sportswear manufacturing.
02:01Inside the suit, there's a membrane that protects against bacteria and is waterproof.
02:05The suit is equipped with sensors for temperature, pressure, and blood oxygen levels.
02:10Additionally, it can track body position in space, allowing doctors or relatives to know if the person has fallen.
02:18Arina's younger brother helped her test the suit.
02:20He wore this suit non-stop for three days, which resulted in denser muscles and improved muscle fiber elasticity.
02:27If the experiment had lasted longer, say 30 or 45 days, the results would have been even more noticeable.
02:33Arina is certain.
02:35The suit was also tested on rowers during training.
02:39The device tracked blood oxygen levels, EMG, and ECG data.
02:43This helped the coach better understand the athlete's capabilities.
02:47Young inventors haven't overlooked IT technologies either.
02:51In 2013, school students from the same city of Nizhny Novgorod became finalists in the Google Science Fair.
02:58Anton Zerubin, Nikita Chernyadev, and Ilya Danilov invented a new digital data storage medium that had no counterparts in the
03:06world.
03:06The boys called it Digital Sandwich.
03:09A medium the size of an A4 sheet and one millimeter thick can store 28 terabytes of data.
03:14The storage medium works like this.
03:17A laser burns structures of varying heights into the surface of plexiglass, looking somewhat like icicles.
03:24As a result, a diffraction pattern appears on the screen.
03:27Then, using a sensor array connected to a processor, the data can be read.
03:32It is encoded in binary, ensuring its preservation.
03:36The main advantage of this invention is the availability and low cost of materials.
03:41Moreover, such a device won't get demagnetized.
03:45Another IT-related invention will surely delight those who constantly forget or lose their laptop chargers.
03:52Guys, from Stavropol, Ilya Sukarev, Emilia Zabrailova, and Emilia Ville came up with a special supplementary laptop charger that runs
03:59on hydrogen batteries.
04:02The core idea is to create a device where four hydrogen fuel cells can be connected in series to achieve
04:08an optimal voltage sufficient to fully recharge one laptop and one smartphone simultaneously.
04:16Hydrogen fuel cells are already actively used in transportation, in stationary power sources for homes, and in small portable devices
04:23for generating electricity.
04:25However, there haven't previously been devices capable of simultaneously charging both a laptop and a cell phone.
04:31The head of the research group, 17-year-old Ilya Sukarev, handled the technical side and designed the charger casing,
04:38which was later 3D printed.
04:41The girls, 16-year-old Emilia Zabrailova and 13-year-old Emilia Ville, wrote up how the project would be
04:47carried out.
04:49The creators are confident that their chargers can easily be used both by tourists on long trips and by people
04:56working in remote areas with power outages.
04:59And this project by 12-year-old Kaliningrad schoolboy Vladimir Dorofov can't be called a full-fledged invention.
05:06But what this boy is doing is no less important.
05:09Vova got into history at the age of 8, when he accidentally found a gas mask pouch from the Great
05:15Patriotic War.
05:15It became the very first exhibit of the museum called Basement with Stories, which is popular in the city today.
05:22Together with his parents, Vova began searching for wartime relics in antique shops, junk shops, and flea markets.
05:30Initially, there were no plans for the museum to expand beyond their apartment.
05:34But gradually, they started running out of space for gas masks, shell casings, and bottles.
05:38That's when his parents suggested moving the collection into the basement right under their apartment.
05:43Vova helped with everything.
05:45Wiring the lights, sweeping the chimney, sorting out the items.
05:49In the end, they put together an exhibition of a thousand artifacts.
05:53And none of them are trivial, says Vova.
05:55Both locals and tourists came to love the museum.
05:58And Vova even created his own signature tour, which attracts plenty of eager visitors.
06:04Here is another impressive invention by schoolchildren, this time from Tomsk.
06:09With their project, Danila Kopsev, Artem Bakshiv, and Daniel Kabanov made the top 5 breakthrough inventions by Russian schoolchildren in
06:17December 2020.
06:18The guys invented the Bat Earth bioreactor.
06:21The plan is to grow cyanobacteria inside this bioreactor, which can release oxygen in volumes several times greater than those
06:29released by plants.
06:31This bioreactor is part of another project called BET, which stands for Bioelectric Tree.
06:38Four years prior, it was created by the current project lead.
06:4111th grader Danila Kopsev, BT Earth, is the first of two reactors the guys are working on.
06:46The second one, BET, a space, is designed to generate oxygen using cyanobacteria on a space station in zero-gravity
06:53conditions.
06:55Initially, the guys wanted to create an electronic tree that would effectively absorb carbon dioxide and convert it into oxygen.
07:01But then, the young geniuses came up with an idea involving bacteria.
07:06In the end, it all led to the creation of a reactor.
07:09Young inventors are also working in the field of artificial intelligence development.
07:13These technologies have been used especially widely in medicine in recent years.
07:17So, a group of schoolchildren from different cities across Russia who took part in the Big Challenges program didn't stay
07:23on the sidelines either,
07:24and adapted AI to assist radiologists.
07:27Now, guided by these student inventors, artificial intelligence has learned to identify specific lung segments where anomalies are present and
07:35can alert the physician about it.
07:37Based on their findings, the students developed a graphical user interface to visualize how their models and algorithms work.
07:44The students are also building an open-source library so that developers worldwide can test and use their product.
07:50This kind of automated analysis of chest cavity scans will make diagnostics more accurate and efficient.
07:56It will also help process screening results faster, filter out healthy individuals, and, most importantly, identify patients with complications and
08:04those in need of emergency care.
08:06It's a great solution for hard-to-reach and remote areas that often lack highly qualified specialists.
08:12So, impressed we definitely are!
08:15Let us know in the comments which project you liked the most, and we're off to prepare new episodes.
08:22Stay tuned!
