water so i'm here today because i want to help those people and make a difference in this world water is the most basic of all needs we cannot live for more than a few days without it and yet most people take water for granted we waste water needlessly and don't realize that clean water is a very limited resource more than 1 billion people around the world have no access to safe clean drinking water and over 2.5 billion do not have adequate sanitation service over 2 million people die each year because of unsafe water and most of them are children this quote is by robert unearther and it fits perfectly in my topic now some of you might wonder what is the actual problem well the problem as i said before is the fact that a lot of people struggles to access the quantity and quality of water they need for living that is why i came up with a solution so first how does my brain work i analyze things and then i research and then i solve i'll tell you a story so you see one time i was on the way we were on the way to my grandmother's house and by the side there was a river in the river i saw a guy he was peeing in the water and i was like let them be that's the only thing people does to that river anyways here in madagascar so i continued the way continued and i saw a bunch of ladies washing their clothes on the same source of river and i was like so they're basically washing their clothes with pee and i was like ew don't you all aren't you all disgusted about that would you wear a clothes if it was washed by pee would you exactly so i didn't do anything yet i continued saying let them be because i was not a life saver i'm not a lifesaver and that was my mistake i cannot stay here and say let them be because as me i like helping people and i hate seeing them suffer as the road went on i saw two guys they were sort of washing their faces taking a shower on the river on the same river that was polluted by the guy the other guy was drinking that water that's even worse than washing your clothes with pee and then i was sad why because they do not know that they can get sick because of that or even die they also don't know that it's not clean so i had to come up with a solution and just yesterday i met i met someone who also already had his a nice way to clean water he's already very advanced but i'm still a child so i'm still doing my own way and um yes a lot of people indeed already has inventions to clean water and so on but mine is different why because mine is five in one what do i mean with that well this tank can one clean water collect rain to dig in ground water three clean the water and for four it functions automatically and five it's effortless what do i mean with effortless nowadays a lot of people actually need efforts to go walk so far and get water well this is my invention i will not go deep about it i'll not go back to in details because i will not have enough time but you if you want more details you can come to me so there are all filtering steps on the side which you can see there's sandstone coarse sand charcoal fine sand and the net these each have their functions which i'm not going to be explaining their use because i'll waste my time and so why do we have to clean the water before using it because it's dirty due to that guy polluting the water or every other people who pollutes the water and the other side there is the tube it can stretch very long i'm still not going to go into details but this can adapt to any type of soil so you do not need to mind if for example your soil is very rocky or fine sand or anything and yes some of you around here might ask i'm gonna be wasting electricity but no since i know that here in madagascar the electricity is kind of a bit of a problem so i had to find an idea which was renewable energy and so this is everything that is automatic in here is powered by a battery which is powered by a solar panel and it works by the sunlight so yes there's a water detector on that water driller bit over there and yes since it's automatic it's going to immediately stop when it detects water and soak it and clean it i have one more question but before that i want to show you a little prototype i made this is just the filtering steps which exactly it works but i just forgot to bring the dirty water and show you all but yes in the future you can guarantee i can guarantee that i'm gonna show you that it works i can also drink it if you want to see me drink it and so in this water in this about this tank this can hold ten thousand liters of water and some people boils to all of you has filtering filter water filters at home some of you boils them like me sometimes we boil the water after it's filtered but since it's still a sketch i can think of adding a fast boiling system under the net so it will be effortless as i said one more question do you all realize that we should help those people who suffers nowadays especi especially in madagascar because they also deserve to live healthy do you so moving mountains is pretty hard but once you start you cannot go back anymore i already did my first step which is this invention over here it might help some people and it might not help some people maybe because of how they think but everyone has their opinion this invention maybe may lead me somewhere far and i decided to take a shot so feel free to come along with me because i want to save the world and together we can all do it but remember everyone's lives matter so if you want to change someone's lives do it if you have an opinion share it because everyone suffers nowadays thank you ladies and gentlemen i hope you learned a thing or two that can help you anywhere and anytime [Music]
