T´asdehe

The problem addressed by T'asdehe is the lack of affordable and sustainable technologies for obtaining and purifying water to combat its scarcity and biological contamination. It is recognized that only 0.01% of the water on earth is potable, so that 884 million people do not have access to it and 2.6 billion individuals do not have access to basic sanitation technologies. In conjunction with this phenomenon, about 36% of the world's population (2.4 billion people) live in areas with water scarcity and it is estimated that 52% will experience extreme scarcity by 2050.  In addition, data presented by the Ecological Threat Register 2020 study indicate that Southeast Asia, the Middle East region, North Africa and Latin America (Chile and Mexico are the most susceptible countries) are exposed to water scarcity. The Global Analysis and Assessment of Sanitation and Drinking Water (GLASS) shows that 45% of the countries worldwide are on track to reach their drinking water coverage goals, however, the remaining percentage stated that they do not have the necessary technological resources to carry out the functions of water collection and purification equitably in rural and urban regions, especially in Latin America and the Caribbean. In the national context, at least 9 million people do not have access to drinking water and it is estimated that at least 13 million receive water contaminated with feces and therefore with a high load of coliform bacteria (disease-producing). Specifically in Puebla there are 31 rural localities, where 47% of the municipalities have drought and 50% or more of the homes do not have drinking water service and there are even communities where 70 or even 100% of the homes do not have the infrastructure for water treatment and collection. In the best of cases, water is supplied by tanker trucks or tanker trucks that do not have the desired microbiological quality. Based on the above, it is emphasized that the traditional methods of water purification, such as reverse osmosis, ultraviolet light and ozone generation, have a high cost and disadvantages; have a high cost and technological disadvantages for their application in rural regions of Puebla such as Eloxochitlán, Ocpaco, San Sebastián Tlacotepec, Tepango de Rodríguez, Coyomeapan, Zoquitlán, Olintla, Chiconcuautla, Huitzilan de Serdán, Teopantlán and Vicente Guerrero. As a result, waterborne diseases such as diarrhea, cholera and other gastrointestinal infections spread rapidly, affecting 75% of the population, especially children, the elderly and pregnant women. 

Without timely intervention, water scarcity will affect all aspects of a society. As agriculture, which relies heavily on water to grow food, is severely affected by its absence, leading to crop failure, rising food prices and, ultimately, hunger and malnutrition. On the other hand, when access to clean water is reduced, it conditions personal hygiene and cleanliness, leading to unsanitary conditions that spread disease and affect the overall well-being of communities.
On a broader level, water scarcity can trigger conflicts and tensions between communities and nations, as limited water resources can become a source of dispute, exacerbating political and social tensions.

T'asdehe, is designed for total elimination of coliform bacteria (it represents indicators of safety as they´re responsible for diseases) and for obtaining water. For the potabilization of the water, a sensor was integrated (that´s activated on contact with water) and emitter of high frequency waves of acoustic energy at 50,000 Hz to induce the phenomenon of cavitation on microorganisms and induce their death. They were introduced in a polyvinyl chloride tubing highly resistant to corrosion, abrasion and chemical degradation, which prolongs its lifetime and reduces the need for frequent replacement, is fully recyclable and can be reused in the manufacture of products to reduce the amount of plastic waste in landfills and contributes to the circular economy. In addition, it includes 1 lithium-ion battery with high energy density and a low carbon footprint compared to other battery technologies such as lead-acid and nickel-metal hydride. On the other hand, for obtaining a water flow through laser cooling of water vapor present in the atmosphere, it was based theoretically on the Doppler effect. That means, a stream of photons was implemented (6 pulsed lasers with a wavelength of 520 nm and power of 5000 mW), which transfers momentum to a water molecule (vapor) efficiently when it´s at the resonance frequency of the water molecule (vapor). The molecule absorbs the photon and receives a momentum proportional to the frequency. When an atom or molecule emits light, it does so in a symmetric pattern in random directions, so on average, the recoil is in the direction of the laser beam. By tuning the lasers slightly below the resonance frequency of the water molecule (vapor) and illuminating the molecule from multiple directions, the moving molecule will experience a Doppler effect that will change the apparent frequency seen by the molecule to favor the absorption of light from those rays that oppose its movement. If the moving water molecule is excited by resonance with a lower frequency than its resonance, the molecule will emit light on average with its resonance. Based on this analysis, in the capital city of Puebla, the relative humidity is approximately 40%. This is a percentage expression of the amount of water vapor present in the air relative to the maximum possible for given conditions of pressure and temperature. This means that in 10 cubic meters of air, we have 4000 liters of condensable water.  

Its application and maintenance doesn´t require trained personnel, ensuring that users can handle it themselves. Additionally, among its characteristics that differentiate it from other technologies is its easy transportation, low cost of $200, maintains the organoleptic characteristics of water (tasteless, colorless, and odorless), and doesn´t require the addition of chemicals to achieve safety and obtain a flow rate of 6,000 liters per hour. Therefore, our objective is to establish its application distributed by zones delimited by the deposits in each municipality with scarce infrastructure, by establishing governmental agreements for its access, thanks to the optimization of our model for widespread application where other technologies are limited.

The solution provided by the "T´asdehe" device represents a significant advancement in the search for sustainable access to clean water, especially in marginalized communities in Puebla, which represent 27% of its population (1,777,485 affected inhabitants) in 6,223 localities, where the availability of safe water is limited such as Eloxochitlán, Ocpaco, San Sebastián Tlacotepec, Tepango de Rodríguez, Coyomeapan, Zoquitlán, Olintla, Chiconcuautla, Huitzilan de Serdán, Teopantlán, and Vicente Guerrero. The target population of this project is composed of people facing daily challenges to obtain clean water, such as those living in rural regions, areas affected by natural disasters, or communities in developing countries.

These communities are currently underserved due to the lack of adequate infrastructure for the supply of clean water and the shortage of resources to implement conventional solutions. Many rely on contaminated water sources, resulting in water-related diseases such as diarrhea, cholera, and vector-borne diseases; posing economic, health system, and psychosocial challenges. The solution provided by T´asdehe addresses these needs as communities would no longer have to depend on contaminated water sources or travel long distances to access safe water. 

The potential impact of T´asdehe on the lives of target communities is significant and multifaceted. Firstly, it improves health and well-being by reducing the incidence of water-related diseases, allowing people to live healthier and more productive lives. By freeing up time and resources that communities can dedicate to other activities such as education and long-term economic development.
On a commercial level, several entities may be interested in the T´asdehe project due to its innovative features and potential to address challenges related to access to clean water. Some of the interested parties may include:
Technology companies and food and beverage manufacturers: Companies dedicated to developing food products that require water sourcing and purification systems could benefit from reducing their production costs and improving efficiency.

Water and sanitation companies: Companies that provide water and sanitation services could see T'asdehe as an opportunity to improve their service offerings and reach areas where they currently have difficulties providing clean water in a cost-effective manner.
Project development companies: Companies specialized in community development projects could be interested in integrating T'asdehe technology into larger projects aimed at improving access to clean water in underserved areas.
NGOs and non-profit organizations: Organizations working in the field of international development and humanitarian aid could consider implementing T'asdehe in their projects to provide clean water to communities in emergency situations or remote areas.
Governments and development agencies: Local, regional, or national governments, as well as international development agencies, may be interested in funding or supporting the implementation of T'asdehe as part of their efforts to improve access to clean water and promote sustainable development.

Our team represents a diversity of talents and experiences that allow us to address the most pressing challenges with a holistic perspective. From engineers, researchers to community development specialists, each member brings unique skills that strengthen our ability to successfully implement this project.

What sets us apart is our deep commitment to the communities we serve. Through years of community work for health and nutrition assessment, we have built strong and trusting relationships with the people to whom we hope to offer this solution. We know their needs, understand their challenges, and value their contributions.

That is why the design and implementation of the T'asdehe project are guided by the direct input of these communities. From the initial planning stages to execution and evaluation, we are committed to working closely with them to ensure that the solution is truly relevant and effective. We are committed to listening and learning from the voices of the communities, recognizing that they are the experts in their own realities. We strive to adopt a participatory approach that allows communities to actively contribute to decision-making and project implementation.

In addition, our team is supported by a monthly board of representatives from various communities in the State of Puebla, such as Ocpaco, Cuautotola, Amixtlán, Miahuatlán, Ajalpan, Cuanalá, Tepanco de López, Zapotitlan Salinas, Zoquitlán, and Huachinango, who share our commitment to sustainable development and community empowerment. We continue to work on involving more representative residents from additional communities. Together, we can leverage additional resources and knowledge to maximize the impact of our work. From a commercial perspective, we have been working for over a year with the local cider company Soamy located in the city of Puebla, implementing T´asdehe in their manufacturing center and conducting a study on the economic and productive impact in this distribution chain.
By offering the T´asdehe project, we are not only providing an innovative technological solution, but also building capacities and fostering human development in the communities we serve. We firmly believe that by empowering people with access to safe drinking water, we are laying the foundation for a more prosperous and equitable future for all.

The T´asdehe project is presented as a prototype due to its innovative nature and its potential to address a pressing global issue: limited access to clean water in marginalized communities. This device represents a unique technological solution that combines high-frequency waves and laser cooling to purify and obtain water efficiently and sustainably.

The innovation behind the T´asdehe prototype lies in its ability to provide a reliable source of clean water anywhere, overcoming limitations associated with conventional purification technologies. Furthermore, its environmentally friendly design and community-centered approach make it an attractive and promising proposition for addressing challenges related to water security and sustainable development.

Being a prototype, the T´asdehe project offers the opportunity to conduct pilot tests in different contexts and communities to assess its effectiveness and viability on a large scale. These pilot tests will allow for adjustments and optimization of the device's design and operation according to the specific needs and realities of each community, ensuring its relevance and effectiveness in the field.

Therefore, I have started with the implementation of Phase 1 (high-frequency water purification) of T´asdehe for 6 months in the community of Ocpaco, Huachinango, within the northern sierra of the state of Puebla. It has around 1500 inhabitants, with a 98% indigenous population, comprising 60% women and 40% men. According to the socioeconomic classification established under the criteria stipulated in my country, they belong to the categories of high and very high marginalization. In Ocpaco, there are a total of 149 households. Of these, 76 have earthen floors, and about 17 consist of only one room. 124 of all the houses have sanitary facilities, 133 are connected to public services, and 146 have access to electricity. The economic structure allows 0 households to have a computer, 0 to have a washing machine, and 85 to have only one computer. The community has water distribution through rivers that accumulate in 4 central community reservoirs. Of the 4 reservoirs, 2 have chlorine disinfection carried out by residents, without government support or financing. In these 4 reservoirs, 50 water samples were taken, all of which contained E. coli, C. freundii, Klebsiella, Salmonella, mainly, justifying the high incidence of gastrointestinal diseases that predominantly affect children and the elderly. There are no official records, as this community does not have hospital services. At the end, a 70% reduction in the incidence of gastrointestinal diseases was observed.

Likewise, we worked with Soamy cider, located in the city of Puebla, by introducing T´asdehe in the water purification part for cider production on a commercial level for 1 year, where the owner obtained various economic benefits and improvements in water quality and safety for consumption through a 69% reduction in production costs, complying with national safety regulations. Based on its implementation, an average reduction of 71% in costs directed towards microbiological elimination treatment, a 51% reduction in energy consumption for its operation, and a general acceptance rate of 98% of the users who used it were observed.

Subsequently, for Phase 2, a laboratory-level prototype of the water vapor condensation cooling laser was designed and developed. Determinations of dew point for the Puebla region (temperature at which water vapor condenses), resonance frequency of water vapor, wavelength, and pulsation frequency of the laser were made to obtain it. The laboratory prototype was intended to mimic the environmental conditions of water vapor present in the air, and through a connecting tube, the laser was introduced to cause the condensation of the molecules for their transition to the liquid state, thus confirming the effectiveness of its use to extrapolate it to a larger scale in the development of the next prototype for commercial use.

For all these reasons, the T´asdehe project represents the starting point for future research and development in the field of water purification and environmental technology. Its potential to transform lives and improve access to clean water makes this prototype an important step towards a healthier, more sustainable, and equitable future for all.

Given the technological innovation that T'asdehe represents, we face several challenges that through the support and experience with specialized knowledge that Solve's experts could provide, would be fundamental to guarantee the success and sustainability of the project in the long term. Such as the following:
-A project finance expert could help identify appropriate funding sources, such as government grants, social impact investors or financing programs for sustainable development initiatives. In addition, he or she could advise on financial management strategies and development of sustainable business models.
-Market barriers: A marketing and business strategy expert could help identify market opportunities and develop effective strategies for marketing and distribution of the T'asdehe device. This could include market segmentation, development of persuasive brand messages, and identification of appropriate distribution channels.

My vision was to address the shortcomings of current methods including reverse osmosis, ultraviolet light, ozone generation, and chlorine use. All but chlorine, need high-cost machinery and constant maintenance by trained personnel for effective operation, making them unaffordable in various areas.

Regarding reverse osmosis, one of its disadvantages is the excessive loss of water due to the separation of two water flows (concentrate and permeate) through a semipermeable membrane. There´s a 2 to 1 ratio (2 liters of concentrated water are discarded for every 1 liter of filtered water obtained). Additionally, it requires an annex system to use this water, may experience filter clogs if not maintained by trained personnel, posing a risk of contamination from leaks or deteriorated filter parts.

Another method is ultraviolet light, which is considered the most effective technology without altering its quality due to the lack of chemical agents. However, the required lamps for its emission are expensive and have a short lifespan, getting unfeasible in various areas. Additionally, while the basis of this technology is the inactivation of microorganisms by damaging their DNA based on the emitted wavelength, it can be interfered with by the presence of colored particles in water.

On the other hand, ozonation also requires high treatment costs, both for installation and its maintenance, as it requires high levels of energy for its operation. Its principle is the dissociation of oxygen molecules through energy discharges to form ozone on-site. While its effectiveness is high and it doesn´t leave any residue, it´s an even more complex technology than ultraviolet light, so its handling and maintenance by trained personnel are indispensable. Additionally, ozone itself is highly oxidizing (requiring contact only with stainless materials).

Finally, the most economical method is the use of chlorine. However, it can interfere with color and taste. Additionally, since its principle is chemical interactions with microorganisms by forming free radicals that cause the breakdown of their molecules, there´s also a risk that, when interacting with nitrogen present in the water, chloramines may form, which are carcinogenic.

For all that, the innovation lies in T´asdehe ability to offer a comprehensive solution that not only purifies water but also obtains it from unconventional sources, such as ambient air, through laser cooling methods. This allows communities facing water scarcity or contamination of the supply, thus significantly improving their health and quality of life. 

Furthermore, our solution not only addresses the problem of water scarcity in a localized manner but also has the potential to catalyze broader positive impacts in this space. By providing sustainable access to water,  T´asdehe can help reduce the incidence of waterborne diseases, improve food security, and promote socio-economic development in vulnerable communities. 

In terms of market and landscape impact, our solution has the potential to change how challenges related to access to safe water are addressed worldwide. By offering an innovative and effective alternative to traditional water purification methods, T´asdehe can influence the adoption of more advanced and sustainable technologies in the field of water security.

Our solution, the T´asdehe project, aims to address the problem of limited access to safe drinking water in rural and peri-urban communities through an innovative and sustainable approach. Our theory of change is based on a series of activities and products that translate into short, medium, and long-term outcomes for our target population.

Firstly, our activities include the development and production of the T´asdehe device, which utilizes advanced water purification technology using high-frequency waves and laser cooling. This device provides immediate access to safe drinking water, without relying on costly infrastructure or constant maintenance.

In the short term, we expect the implementation of our T´asdehe device to have a direct impact on improving the health and quality of life of the target communities by providing them with access to safe and reliable drinking water. This will be reflected in an immediate reduction in waterborne diseases and increased satisfaction of basic needs among the population.

As our project expands and is adopted in more communities, we anticipate seeing medium-term outcomes in terms of improved food security and socio-economic development. Sustainable access to safe drinking water will enable communities to dedicate more time and resources to productive activities and enhance their resilience to water scarcity-related crises.

Finally, in the long term, our theory of change foresees a significant impact on improving the quality of life and overall well-being of communities, as well as promoting autonomy and self-sufficiency. By providing a sustainable and accessible solution for access to safe drinking water, we aim to catalyze positive change in the global landscape, promoting more efficient and environmentally-friendly practices in the water and water security field.

This theory of change is based on evidence collected through third-party research, impact evaluation data and interviews with the target population through the monthly meeting with representatives of various communities in the State of Puebla that is based in Ocpaco Huachinango, which They support the effectiveness and strength of our logical links between activities, products and results.

The impact objectives of our T´asdehe project are as follows:

Improved community health: Our goal is to significantly reduce the incidence of waterborne diseases in target communities. We measure our progress through indicators such as the rate of gastrointestinal diseases related to the consumption of contaminated water, which we aim to steadily decrease as our solution is implemented.

Equitable access to safe drinking water: We seek to ensure that all people, regardless of their geographical location or economic resources, have access to safe and reliable drinking water. We measure this objective through indicators such as the coverage of the T´asdehe device in rural and peri-urban communities, ensuring it reaches the most needy areas.

Environmental sustainability: We are committed to reducing the negative environmental impact associated with water sourcing and purification. We measure our progress through indicators such as the amount of water purified using our device compared to conventional methods, as well as the reduction of waste and energy consumption.

Community empowerment: We aim to strengthen communities' capacity to manage and maintain their own drinking water systems. We measure this objective through indicators such as the number of people trained in the installation and maintenance of the T´asdehe device, as well as the level of community participation in water-related decision-making.

To measure our progress towards these impact objectives, we regularly collect data on the aforementioned indicators and analyze them in comparison to our established goals. Additionally, we maintain direct contact with beneficiary communities to gather qualitative feedback on the perceived impact of our solution on their lives and environments. This combination of quantitative and qualitative data allows us to continuously assess our progress and make adjustments as needed to achieve our impact objectives.

The physical principle on which the project's operation is based takes the sound wave as the basic unit, which is defined as an elastic wave that requires a medium to cause vibration, in this case water, and it is the medium itself that produces the propagation of these waves with its compression and expansion. It is also transferred to the structure of the microorganisms present in the water, causing the destabilization of their morphology and, consequently, death.

On the other hand, the second principle of functionality is based on temperature, which is a measure of the energy of the random movement of the atoms and molecules that compose a substance. Cooling a gas involves decreasing the random velocity of its constituent atoms and molecules.

To stop an object in motion, a force must be applied, i.e., the transfer of momentum. In this sense, the average velocity of a water molecule is 450 m/s at room temperature, and the distribution of its velocities is narrow. If the goal is to reduce velocity, a way to transfer enough momentum to slow it down must be found, inducing cooling.

Chu et al. (1997) first defined laser cooling as the process by which a physical system loses thermal energy through the transfer and annulment of the linear momentum of the atoms with collisions and photon emissions from a laser source. By using photons produced by lasers, resonant or quasi-resonant energy exchanges are induced by transferring linear momentum between atoms and light. In this regard, a beam of light transfers momentum to a molecule efficiently when it is at the resonance frequency of that molecule.

Regarding laser cooling, it is a beam of light or a stream of photons that transfers momentum to a water (vapor) molecule efficiently when it is at the resonance frequency of the water (vapor) molecule. The molecule absorbs the photon and receives a momentum proportional to the frequency. When an atom or molecule emits light, it does so in a symmetrical pattern in random directions, so on average, the recoil is in the direction of the laser beam.

By tuning the laser beams slightly below the resonance frequency of the water (vapor) molecule and illuminating the molecule from multiple directions with them, the moving molecule will experience a Doppler Effect that will change the apparent frequency seen by the molecule to favor the absorption of light from those rays opposing its movement.

If a moving water (vapor) molecule is excited by resonance with a frequency lower than its resonance, the molecule will emit light on average with its resonance. In this sense, energy conservation implies that the extra energy of the light comes from the kinetic energy of the molecule, so the water (vapor) molecule cools down to the dew point as it disperses the light, thus achieving the condensation of water vapor.

As developers of the T´asdehe project, we have conducted exhaustive testing and validation to ensure the effectiveness and reliability of our technology. Our approach includes laboratory testing and field trials to assess the performance of the T´asdehe device in purifying and obtaining drinking water. An experimental study was conducted involving the development and implementation of a controlled intervention to verify the effectiveness of microorganism removal and water extraction through laser cooling of the vapor present in the air.

Laboratory tests involved simulating various water quality conditions to evaluate the efficacy of our purification methods. We tested the device's ability to remove coliform microorganisms (phase 1) by seeding samples of water (50 ml) collected from the toilet and kitchen area of ISU University on nutrient agar, EMB agar, and MacConckey agar culture media. Bacteria quantification was performed in triplicate using the serial dilution technique (base 10) of the original liquid samples. These tests provided valuable data on the device's purification efficiency and its compliance with safety and quality standards until achieving 0 CFU. For phase 2, the laser cooling device for condensation of water vapor from the air was designed and implemented. Determinations of dew point for the Puebla region (temperature at which water vapor condenses), resonance frequency of water vapor, wavelength and pulse frequency of laser, and other physical, mathematical, and engineering determinations were made to meet the conditions for its effective application.

Additionally, we conducted field tests with phase 1 in the Ocpaco and Soamy communities, as well as partnered with representatives from communities facing water scarcity or contamination issues. These tests allowed us to evaluate the performance, effectiveness, monetary, and energy costs of the device under various environmental conditions and usage scenarios. Water samples were collected before and after purification to analyze the reduction of contaminants and ensure that the quality of the purified water complied with regulatory standards. We are finalizing the adaptation of the phase 2 prototype for implementation in the Ocpaco community.

To provide evidence of the effectiveness of our technology, we can share links to these articles and academic publications, which are publicly available and demonstrate the robustness and reliability of the technological and theoretical foundation considered in our approach. These scientific validations serve as the basis for the effectiveness of the T´asdehe technology in addressing water purification challenges and improving access to safe drinking water for communities in need.
