00:00hello viewers I am president right here at IIT Delhi and here's a lot of students all
00:08over from all over the country has you know exhibited a lot of projects on
00:13environment now we'll talk to the project revolt right how they are making
00:19change into the you know climate crisis and all so tell me your name from which
00:25my name is Divesh I am from Gurgaon Amity International School sector 46 I am Arush
00:32from Prometheus school in Noida hello I am Amog and I am from Lucknow city
00:38monastery school I'm Ronak and I'm from Heritage International in Gurugram so
00:44what you guys have developed and you were telling me that cycles will produce
00:48electricity while you ride it from the problem we identified was that there are
00:53so many students who use charger electrical appliances so that elect those
00:57electrical appliances produce 1.5 thousand CO2 emissions per year we
01:02wanted to reduce the number and provide an alternative to the students so we made
01:06this first prototype so how this works is basically when you cycle it attaches
01:11somewhere over here so thank you so when you rotate the cycle rotate ora so through
01:18this the the dynamo motor rotates which generates AC current now we are converting
01:23that AC current into DC through bridge rectifier so that we can then charge them
01:28you can charge your phone batteries power bank cycle flashes you can use it for
01:34multiple purposes so right now there is this prototype this is a first one and we
01:39are already generating two to three volt of current right now so it is enough so you
01:44would have seen that like LEDs of the cycle so we are able to generate much power so
01:52that we can just light it up so as we know 46 percent of students cycle and have average
02:04distance traveled by a student 2.5 km right so we can actually we thought we can use this for good of
02:14the environment so we just build this prototype and from this we can prevent
02:18that 1.5 k CO2 emissions per year by each student so rather than yes rather than using it
02:27rather than using charges from directly like these ports right there we can just charge it from
02:35there and save our time as well we had two aims with this project first was to
02:41obviously the environmental benefit because instead of charging from coal based energy
02:46now we use now we just convert the kinetic motion into electrical energy but the second
02:51very important aim was also to promote cycling as a whole because of all the
02:54physical and health it's good for your health that's why we promote cycling through our campaign
03:00which you can subscribe to on our instagram we have an instagram page as well so actually we
03:05have two projects one is the piece electric tile one is this so the name is urja loom x revolt ride
03:10revolt ride is the name of this and urja loom is basically the other prototype you guys are planning to do
03:17some engineering in the future yes ma'am most of us are studying abroad and b-tech while he is pursuing
03:26like we are in 11th grade and most of us wanted to pursue engineering he is a commerce i'm a commerce
03:36student because this is a great opportunity for even a commerce room to learn a lot of new skills
03:43they all handle all the electrical aspects but there was also a lot of stuff for me to do and learn
03:49and this was a very good learning opportunity even though i did not focus a lot on you tell me your
03:54name and your college so i am manshrika bhat from dr rajendra prasad kendra vidyalay so as we see food
04:02wastage is one of the most serious issues throughout the globe so what happens is we cook the food and we
04:09forget about it so humne kya kya hai we have created a khana clock which we will stick on our fridge
04:15so if you guys uh if you imagine that you have cooked rice today so if you are not able to finish
04:23the rice on that day so you can place the token on the fresh zone but later on one day older if the food
04:29gets then you will ship the token on you soon that you can use it soon but if uh later on you are not
04:36able to use the food after this position or even after this position then you will ship the token on
04:43use now that means you have to use the food now only otherwise it will get wasted and ends up in a
04:49landfill so we also have a qr code here which leads to our website so here is our website yeah so yeah
04:59thank you so building on what she said we have a website where we're giving you different categories
05:04right if you want to repurpose the leftover food because we don't want the same taste again and
05:08again isn't it so we're giving you different categories and you can choose a category in which
05:13you'll get get different recipes to repurpose that food supposedly if you have an ingredient that
05:19doesn't match these categories we have also integrated an ai chatbot into it where you can
05:24just simply give the ingredients and it'll give you a recipe in behind okay so there's also this concept
05:28that maybe you don't want to eat the food that was left behind right that's a day old or maybe like that
05:34so what you can do is we can also connect you to an ngo so that it can collect the food from you and
05:39give it to somebody who's in need of it that is the basic concept of the khana clock and that is how
05:44we've tried to work this basically we're trying to make a change in the habit of people even in kids
05:49and if possible in adults also now we'll move forward to the next project these people are doing but let me
05:55tell you in between that these students are mentored by iit professors and these students are from all over the
06:03country they are 12th grade students 10th grade students and first year and second year students
06:07also so uh what i what is your name and from which school or college okay so my name is nishta i'm in
06:14first year from i'm pursuing psychology honors from delhi university so what your project is on can you explain
06:21me something okay so our project so our broad topic was what is scarcity us may households may we took
06:28and we noticed that out of all the waste water that we generate 68 percent of it is gray water so and
06:36gray water is or pura paani apart from toilet wala and so we thought if we could reuse that water
06:44so we will reduce the bought sara paani joe waste hotel usse come kar payenge to us may we made this
06:51filtration system iit has mentored this boot camp from 9th june to 27 june today is the last day and
06:58these mentors have given the students opportunity to uh you know put the their projects into
07:03exhibition now we'll move forward to next project of the students uh hi your name first and from
07:10which college and i'm from amity international school so we are the drinking water contamination team
07:16and we are working on the project of providing clean drinking water to rural areas our target audience
07:22is the low-income families and for that we have created this prototype in which there are many layers
07:27about so that we can purify the water so for the primary research we checked water in eight areas
07:34and we collected the data from these eight areas and we checked for 16 contaminants in the water
07:38so out of all these eight areas we checked that two areas noida sector 78 and kishin girl there were a lot
07:44of contaminants these were our statistics this is uh these were the contaminants before filtration so
07:51it uh it went around 15 to 1600 ppm but after filtration which we did with this it went to
07:58almost 300 to 400 ppm so i think we have achieved the greater and this is also portable because if we
08:05are going for camping or trekking right they're not going to carry a five liter bisleri bottle just to
08:10you know just for drinking water but they can use this and if there's any water source like a pond or
08:16a lake so they can use this to filter their water and purify it move to the last project students are
08:21showcasing so what's your name and from which uh school or college so hi i'm ayushi kapoor i'm a grade
08:2911 i'm a grade 11 student and i'm from arvachin bharti bhavan senior secondary school vivekviha delhi
08:36anything you want to elaborate on your project yeah so we are team neer veer we are working on the problem
08:42of water scarcity due to over irrigation hi i'm anj and i am a cac major first year at uh vit wellor
08:51so i'll i'll explain it in a very playful way so consider her a farmer okay hi farmer so what she does
09:04is she grows rice okay and i love my crops yes and uh she lives in gaziabad yeah so when you love your
09:16yields you rely on guesswork you're like it it shouldn't be less but it could be more right now
09:26this makes them think that this is not even a problem to be addressed
09:31but it is because it leads to over irrigation and over irrigation leads to wastage of energy
09:39it uh you know it uh brings out bad yields which can which has a food security concern itself right
09:50so we decided to counter this problem how did we do it we made ramban ramban is an all-in-one solution
10:01so which which introduces farming and data so this is part one soil node it is powered by solar energy
10:11it has an esp32 microcontroller inside it what the esp32 does is very exciting which i'll convey later
10:19now introducing the sensors we have a soil temperature sensor here we have a soil moisture
10:25sensor sensor here and we have one such contraption here which will show you a live test of
10:34moving to part two this is a small box but it has a big role so she lives in gaziabad right so when you
10:43open your forecast app you'll you'll get weather data for all of gaziabad you won't get it for your
10:50own farm right this does that you have a rain sensor here you have a bme 280 sensor here which gets your
11:00temperature and humidity based on this it collects data this collects data this also has an esp32 sensor
11:07inside it and using that what an esp32 does is it hosts wi-fi locally so they start talking to
11:16each other yeah i have rain data i have soil data cool let's convey to our senior who's the senior the
11:22farmer so the so the farmer can host a website and it shows all the data here for example let's open the
11:31soil moisture data and as you can see two nodes will have similar values because they're suspended in
11:38the air but one node will have a value which is different because it is in the soil based on this
11:47the farmer can take calculated decisions or related to fertilize the you know manners and all
11:55now you have it conveyed to your senior right but how does it fix the water problem it fixes it using
12:03this this is a water pump it's small for now but when we scale it it will be bigger so you attach it
12:09to your tube well and magic happens the tube will gets automated the farmer doesn't even have to water
12:16his crops so it not only saves water it also saves on energy and it's all that food security
12:25issue which is why it is named ramban
12:32now a major question could be don't such systems already exist similar system do exist but they
12:42work on cloud networks cloud networks are online our solution is offline so it is also compatible for
12:52hilly areas my name is samvit so what you guys are like um doing on this environment thing what your
13:00project is our project is on micro plastics so microplastics is a really big issue right plastic is
13:05used everywhere it's used in pen caps bottle caps is used in pet drinking bottles it's used everywhere and
13:12the statistics are pretty significant because 210 000 microplastics go in our environment and 210
13:18plus go in our body and from things like laundry alone right you might think that you just wash
13:23clothes nothing will happen right 1.5 million synthetic fibers go into the uh marine ecosystems from one
13:30wash of ours at home and it contributes to 35 to 40 percent of all marine ecosystem microplastics just our
13:36laundry at home so that's what we aim to target with our prototype what is your name and from which
13:41school yeah i'm prasanna power i'm from pune and my school is snvp international school can you explain
13:47me about this project you are doing with the data you have mentioned in the board yeah so first we worked
13:52on detecting the microplastics through stereo microscopy we found we took samples from the yamuna river
13:58ourselves and samples from yeah and samples from the agricultural soil to detect microplastics
14:03microplastics we even went a step further to divide them by color and by plastic type so first we worked
14:09on a prototype this is what it would look from the inside there's there's muslin cloth of 90 microns
14:17and there's also granulated granular activated carbon so first we yeah first we passed microplastic
14:25contaminated water through this which looked something like this and after filtration it looked like
14:31this which is pretty clean because the microplastics get attached to the muslin cloth and the gse as
14:37we can see over here so actually what we have here is that we are employing a chemical adsorption system
14:44and a physical filtration system because the muslin cloth has a porosity so that it can trap the
14:49microplastics physically but the gse has been proven by studies and literature review which was a key
14:54component of our project that it can efficiently add chemically adsorb and bind the microplastics so
15:00chemical and physical is what makes our thing like more efficient and effective you guys are doing
15:05this uh saving like saving earth from microplastics only on textile like only on clothes on what i'll tell
15:11you uh first we detected after that we have built in a technique which filters out microplastics from water
15:18and that thing can be used further for example this can be used in washing machines to
15:26so if we want to build a circular economy we want to you know upcycle this these microplastics what we
15:31can do is that after this the microplastics are still there so if we want to build a circular economy we
15:37we want to you know upcycle this these microplastics what we can do is that after when we reuse it and
15:58we'll wash this this uh this cranial activated carbon with water that water will contain microplastics and
16:05we were working under a phd student she has already tested and proven this thing so that water when
16:11we use that to form concrete our tiles and all these things these microplastics don't leach out they get
16:19stuck there so they won't affect anything they won't leach out they won't harm people around us so
16:24what we can do when we demolish it so like this what we can do we can keep on upcycling this thing so
16:30microplastics can reduce or upcycle can also be supported in all these things so
16:37the effects of microplastics can tell us please tell me your name and from which college
16:44i'm archisha sharma i'm doing for i'm in p-tech first year doing it from i'm doing it from vips
16:50college ipu university anything you want to elaborate on so actually to understand the problem first tell me
16:57your name and like from which college um i'm vanya rena i'm a 12th grader from dav vbdiv public school
17:03delhi only so actually you see to understand the problem statement we actually fell you know joined
17:10phd scholars in their day-to-day routine and worked with them so we actually went to nram lab of center
17:17for rural development and i uh technology iit delhi and we worked with yamuna water samples which we got from
17:22virgin agar delhi and we like and and we were able to find these structures out like when you order
17:29stuff from blanket the vegetables come in a net now so these are those nets it's kind of harmful
17:35you see all the vegetables that are grown in delhi ncr region now they are actually a part of yamuna
17:42yamuna water gets into them or yamuna water may kaafi textile run-up hota agricultural waste
17:47so that's a pressing concern like and they get into your body then and just out of curiosity we
17:56also worked on the soil samples which we got from jabua delhi soil samples and we were able to see
18:04like some really surprising images like all these stuff are micro microplastics this big structure is
18:10a microplastic this is a microplastic this is a sample actually we worked on what if i tell you
18:18this thing contains all these things we did stereoscopy of this thing and we were able to find out these
18:24microplastics in here and when she was talking about health microplastics they have been studies
18:30it's proven microplastic is there in our blood brain even when a mother breast feeds her child in
18:37that milk also microplastics have been found and tear carcinogenic tear cancer causing thing is
18:42ki microplastics according to a research arthur et al 2009 microplastics are those plastic particles
18:49which are less than five microns in size but when they get into your body they disintegrate and they
18:54are like they then get into the size of less than one micron so then they turn into nanoplastics and
19:00those nanoplastics leach into our bloodstream they get to our brain they get to our human heart and then
19:06they they cause us cancer and all the big health problems that you know and another fun fact all
19:11that you know 35 percent of the cancer deaths are actually because of exposure to those plastic
19:16particles that we have everywhere around us
