Life saver water multi functional tank | Luz Miaina RAFALIMANANA | TEDxYouth@Antananarivo
A speaker argues that clean water is a limited global resource, citing that over 1 billion people lack access to safe drinking water, and introduces a novel, self-contained filtration system that collects rainwater, digs groundwater, and filters water automatically using only solar power. The speaker illustrates the necessity by observing pollution in a Malagasy river, prompting the creation of a five-in-one solution designed to provide clean water effortlessly.
## Speakers & Context
- Speaker advocating for clean water access and presenting an invention.
- Context involves highlighting the global scarcity and pollution of clean water, specifically in Madagascar.
- The speaker frames the act of presenting the invention as a commitment to making a difference, comparing it to *"moving mountains."*
## Theses & Positions
- Water is the most basic of all needs, and clean water is a very limited resource.
- Many people take clean water for granted, leading to needless waste and lack of sanitation.
- The core problem is limited access to both the *quantity* and *quality* of necessary water for living.
- The speaker’s invention offers a unique solution that is "five in one" and "effortless."
- Change requires taking action, and the speaker feels compelled to help because they "hate seeing them suffer."
## Concepts & Definitions
- **Safe clean drinking water:** A necessary resource that more than 1 billion people globally lack access to.
- **Adequate sanitation service:** Lacking this service impacts over 2.5 billion people globally.
- **Five-in-one:** The description of the invention's primary functions: 1) collect rain, 2) dig in groundwater, 3) clean the water, and 4) function automatically, plus a fifth element contributing to its function (implicitly solar power/effortlessness).
- **Effortless:** Described as a contrast to modern life, where people often require effort just to walk to fetch water.
## Mechanisms & Processes
- **Personal Problem Analysis:** The process involves analyzing a situation, researching, and then solving the identified problem.
- **Pollution Observation:** Witnessing individuals using a river polluted by defecation and laundry washing.
- **Invention Functionality (Filtering System):**
- **Input Collection:** Can collect rainwater and dig for groundwater.
- **Filtration Steps (Sequential):** Sandstone $\rightarrow$ coarse sand $\rightarrow$ charcoal $\rightarrow$ fine sand $\rightarrow$ net.
- **Groundwater Adaptation:** A tube that can stretch long and adapt to any soil type (rocky, fine sand).
- **Energy Source:** Powered by a solar panel charging a battery; includes automatic operation and a water detector.
- **Purification:** Can include an optional fast boiling system under the net, in addition to filtering.
## Timeline & Sequence
- Past observation of pollution: The speaker recalls seeing a man peeing in the river, followed by ladies washing clothes in the same source.
- Realization: The observation leads to the realization of the danger, as two men were observed bathing and one drinking from the polluted river.
- Solution Development: Meeting someone who already had an advanced water purification way, inspiring the speaker's own, distinct design.
- Demonstration: Showing the working prototype (though the dirty water was forgotten).
- Future/Goal: The system *can* eventually be upgraded to include a fast boiling system.
## Named Entities
- **Madagascar:** The geographical location where the polluting and subsequent solution observation took place.
## Numbers & Data
- **1 billion+:** People lacking access to safe, clean drinking water.
- **2.5 billion+:** People lacking adequate sanitation services.
- **Over 2 million:** People who die each year due to unsafe water.
- **Ten thousand liters:** The capacity of the main water tank.
## Examples & Cases
- **Pollution Example (River):** A river in Madagascar where the speaker observed a man urinating, followed by women washing clothes there, and subsequently seeing two men washing and one drinking from the same polluted source.
- **System Adaptation Example:** The grounding tube can adapt to soil types that are "very rocky or fine sand or anything."
## Tools, Tech & Products
- **The Water Filtration System:**
- **Components:** Tank, sandstone, coarse sand, charcoal, fine sand, net, groundwater drilling tube, solar panel, battery, water detector.
- **Function:** 5-in-one system for rainwater collection, groundwater digging, water cleaning, automatic operation, and being effortless.
- **Prototype:** The visible filtering steps displayed (sandstone, coarse sand, charcoal, fine sand, net).
- **Solar Panel:** Powers the battery; powers the automatic functions.
- **Water Detector:** A feature on the water driller bit that stops the system when water is detected.
## References Cited
- **Robert Unearther:** Source of the statistic: "more than 2 million people die each year because of unsafe water."
## Trade-offs & Alternatives
- **Alternative/Current Methods:** Boiling water after filtration, which the speaker notes some people do, but seeks to make the process effortless.
- **Existing Tech:** Acknowledges that "a lot of people indeed already has inventions to clean water."
## Counterarguments & Caveats
- **Power/Electricity:** Anticipates the question about wasting electricity but counters with the use of renewable energy (solar panel).
- **Detail Limitations:** States clearly that they will not go into details because they will "waste my time."
- **Prototype Status:** Acknowledges that the currently displayed prototype is *not* tested with dirty water, and the speaker will guarantee a demonstration later.
## Methodology
- **Problem Identification:** Direct observation of environmental and health crises (pollution in Madagascar river).
- **Solution Design:** Developing a multi-stage, low-energy mechanical filtration system.
- **Sustainability Focus:** Utilizing entirely renewable energy (solar power) to address unreliable local electricity grids.
## Conclusions & Recommendations
- Everyone has the right to live healthily, particularly those suffering in Madagascar.
- The speaker's invention is presented as the first vital step toward saving the world.
- Call to action: People are encouraged to "share it" (their opinion/effort) because "everyone suffers nowadays."
## Implications & Consequences
- Successfully implementing the invention could provide sustainable, decentralized clean water sources in underserved communities.
- The success of the model could inspire larger-scale efforts, as the speaker anticipates the invention "maybe may lead me somewhere far."
## Verbatim Moments
- *"greetings nowadays a lot of people suffer due to the use of unsafe water"*
- *"more than 1 billion people around the world have no access to safe clean drinking water"*
- *"over 2 million people die each year because of unsafe water"*
- *"i was like let them be that's the only thing people does to that river anyways"*
- *"they're basically washing their clothes with pee"*
- *"i'm not a lifesaver and that was my mistake"*
- *"Mine is different why because mine is five in one"*
- *"it's effortless"*
- *"i will not go deep about it i'll not go back to in details because i will not have enough time"*
