Ground-based scientist and unique water pumping system

He claims, only 5,000 VND can own a . energy-saving pump (!). According to him, this initiative is not only good for irrigation but also good regardless of which areas need to pump water with large capacity, including pumping water for high-rise apartments.

Mr. Tong Van Dung at TechMart Technology Market 2005

That is Tong Van Dung - Hanoi's "barefoot" scientist who has just finished grade 7.

To confess, if not for the hand letter of Prof. Nguyen Lan Dung, Chairman of the Program voluntarily brings science and technology advances to farmers, I think, he is a crazy guy. He also admitted that he was not normal because no one like him for three years just "ate meals for prisoners and general goods".

His terrace turned into an experimental workshop, and every day one saw a man in his 40s struggling with the scrap of iron, screws, and wires and then dismantling and disassembling the disorder.

At first, his family and friends supported him tremendously, but after seeing that forever, he did not get anywhere, many people began to feel discouraged. Seeing that he neglected to take care of "rice and rice money" for his family, so did he bring money to the experiments, many people began to think "this is crazy".

Results from sweat, tears

" Because I had no conditions, I had to give up my studies to go to the army. Dismissed, I went to work all kinds of jobs, from workers, motorbikes, electric and water repair workers . Someone once said it straight. In my face: People with this degree, I don't eat anyone, let me know, if I do not run out of secondary school, I can't do anything, but for some reason, the blood of research and research seems to be absorbed so I don't give up. "he said.

His wife was a gentle, quiet person, so she could not bear many times throwing his labware on the road. Even now, just listen to whoever talked about his research on the pump was mad. Perhaps because of that, it was only a matter of time for him to make an appointment to stop me from going to my house.

Promptly questioning, he scratched his head, scratching his ear: " Wait until your wife is not at home, or die immediately". Saying that, his voice suddenly became sad: "Saying that, I also know that she has to endure a crazy guy like me who is very great. Sometimes she loves her very much, but she only eradicates the experiment a few days later. That, itchiness is too much to pull out .

Few people know that, he is the author of the idea of ​​traffic division of Crossroads Department (Hanoi) in SEA Games 23 with a soft separation solution. This idea was introduced by a Ph.D. of the Military Technical Academy in the Transportation newspaper and then applied somewhat to practice.

Or as an idea for oxygen athletes to recover health, the idea of ​​"treating the Red River" by opening up, expanding the flow . However, for him, the idea of ​​the most successful implementation and also It is a lot of effort, money, even sweat and tears are the most energy-efficient water delivery system.

Not for sale - just want to transfer free

At first, when I first heard you present, I did not believe it very much, only when I witnessed the operation of my own system, I was really convinced. Without priming water, just lift the pump lightly, the water has spilled out of the tube itself.

He asked: " Have you ever waved a pen, have you noticed anything? ". Seeing me still surprised, he answered: " Squid shot right? Shoot away or close to depend on your waving force. So why is such a simple thing that we do not apply to produce hand pumps? In fact, there is no need for any advanced knowledge, it is all basic knowledge that we can learn at school, if we know how to apply it, it will be effective when we cannot expect it . "

He said this idea was formed once the family dug a well. Seeing the hands-on workers bump up the pipe once the water pops up - a flash of thought in his head: Why not use this method to pump water?

For three years, doing a lot of experiments on the model with many principles such as leverage, counterbalance ., in the end, he discovered, based only on 7th grade physics knowledge: Water pumping system uses the laws of nature (Earth gravity, friction inertia .).

In fact, the "pump" that Dung often calls must be construed as "The system brings water up to save energy" but cannot be called a machine. This system is extremely simple because it takes advantage of waste parts such as chains, bearings, bicycle rims. If you want to bring the water to a moderate height, just need water pipes, one-way valves, chains, shafts, belts and motors to transfer speed. Once the pump can pump water out at many ends.

The system has the advantage: simple in both structure and tool (available on the market), saving at least half of energy compared to using conventional pumps. A big advantage of this system is that it is possible to increase the capacity of the pumped water without additional power, just have to install some simple tools such as water pipes, heavy fruits . However, the disadvantages of the system is bulky.

Mr. Dung said, because this system is extremely simple, easy to use, so it is particularly suitable for rural areas. Only 5,000 VND is required to own a water pump by hand, while the machine with a pump capacity of 10m3 / second costs about 2.5 million VND. Currently he has successfully researched the use of batteries to operate the system. He is continuing to research and produce electricity from this energy-efficient water pumping system and initially had very positive results.

When I asked, why did he bother with this project, he said it was because he always thought about how to help farmers who can actively pump water at the cheapest and easiest price? . Therefore, in the past two years, people still see him appear in industrial and agricultural equipment exhibitions . to introduce products.

Then people find him diligently going to knock on the doors of each scientific institution, managing to expect someone to take over the product he makes - even if it's just for free. He said in a very sad voice: " I only hope to receive the attention of a state management agency once. They only verify and make a conclusion whether my product is satisfactory or not. But It is too difficult to meet them . "

Most recently, he brought " Energy-saving water pumping system " to TechMart Technology Market 2005. Thereby, he received many technological transfer requests from all provinces and cities throughout the country. . But he always reminded himself again and again: Only want to help people and not sell. He never thought of going to copyright.

" Copyright does when it is so simple. And I want more and more people to know this solution as well so people will spend a great deal of money on using electricity, but the effect is very high. If anyone is invited, I am willing to come to the place to transfer technology .
