A solar powered device that transports safe water to villages for drinking and basic sanitation would represent a global socioeconomic transformation for literally millions of women and female children who spend hours every day fetching enough water to survive. MRT plans to commercialize Thermal Simplex Fluidic Pump (TSFP) technology for irrigation, municipal potable & waste water pumping, and long distance aqueducts and pipelines. Once commercially viable, proceeds will be used to make low cost, highly reliable, long service life models for service in underdeveloped regions of the world where women and children are suffered by manual labor for water transport. MRT will offering TSFP technology to governments and NGO’s such as UNICEF, WHO, etc., who currently spend large amounts of money on less dependable technologies. MRT will also work with local non-profits and community organizers to foster implementation directly to communities that can afford such systems, cultivating micro-financing infrastructure for less capable populations, and grant systems to the destitute.
In tens of thousands of communities and villages around the world, the task of gathering water falls on women and female children, who in many cases, must travel over dangerous terrain to reach the nearest supply. Women and children are especially vulnerable on these long daily journeys over predictable routes. The UN estimates that women and girls spend more than 87 billion women-hours per year collecting and transporting water. The round trip distance suffered by the average women living in rural India is six kilometers per day. Pregnancy or illness does not excuse a woman from this duty. Female children are in many cases preempted from attending classes because of the time it takes to gather water.
Maintenance in underdeveloped countries is extremely difficult due to the lack of infrastructure, trained personnel, and money. Solid state design is imperative for reliable operation of any system. In many regions, the level of education is so profoundly deficient, that replacing or cleaning a common filter element presents a challenge. This is often true even when persons within the served community have been trained for that very task. In underdeveloped communities, high technology solutions to health and welfare problems will fail if they require a level of maintenance that exceeds the expertise and education of the general population being served. They will also fail if the cost of maintenance exceeds a community’s economic resources.
The use of conventional pumping technology to provide water collection and transportation to rural, First Nation, and underdeveloped communities is plagued by the following problems:
1. the capital cost of mechanical pumps is high
2. moving parts ultimately require replacement
3. electricity and fuel are expensive, unreliable, and often unavailable
4. high discharge pressure and flow rates require high power motors or engines
5. due to high power requirements, solar PV electric supply is not economically feasible
6. filters are often required to protect pump components from muddy or turbid water
7. traditional pumping system have short service life (major overhaul every ~5 years)
8. installation of traditional pumping systems require highly trained personnel
9. maintenance of traditional pumping system require highly trained personnel
A water transportation system that fails to address any of these critically important metrics is doomed to failure. Accordingly, any viable solution set must include the following operational imperatives:
1. solid state construction, i.e. no moving parts
2. powered by low grade thermal energy (such as solar)
3. require no electricity or fuel
4. comprise high power density (power versus size)
5. produce suction pressure (gravity feed not feasible)
6. have no discharge elevation limit
7. have no discharge distance limit
8. immune to highly turbid water and debris
9. maintenance free
10. scale over a broad range of pressure and flow rate capacities
11. easily manufactured
12. low capital cost
13. zero operational cost
14. service life of +20 years
In response to this need, May-Ruben Technologies has designed a Thermal Simplex Fluidic Pump (TSFP). This innovative pump satisfies all fourteen objectives listed above.
