The solar-powered cyclo of 3 Da Nang students

It sounds strange but it is a very unique invention. The meaning of this product promises to contribute to diversifying the type of tourism in Da Nang and Hoi An markets .

With new innovations, high practical application capabilities, "Solar powered Cyclo" by 3 friends Pham Hong Truong, Nguyen Thanh Minh (Project Management Department) and Le Hoang (Electrical and University Faculty) Da Nang Polytechnic) has excellently won the high prize in the 2016 "Design of energy-saving products and climate change response" contest organized by Danang Department of Science and Technology.

Pregnancy from the tour of Hoi An ancient town

After the tour of Hoi An ancient town (Quang Nam), images of drivers sweating, buckling on the cyclo in the harsh weather printed in the minds of 3 friends Truong, Minh and Hoang. It is the love image that is the motivation and the catalyst to help you conceive the idea of ​​inventing a cyclo driven by natural energy, instead of using human power.

Incubated for many years of care, all three cannot confidently carry out because of limited conditions. It was not until the Department of Science and Technology of Da Nang cooperated with the Polytechnic University Delegation to launch the Contest on designing energy-saving products and responding to climate change. All costs must realize the dream of burning for a long time in the hope that the "child" will be present in the middle of everyday life.

"We are all from a purely agricultural family, food and clothing, and school fees must be run at every meal, so it is very difficult to invest in scientific creative interests. Therefore, All materials for new cyclic inventions must first ensure cheap, easy-to-find criteria, and sunlight is a natural energy source that we first think of when researching products. This " , Pham Hong Truong (team leader) shared.

After choosing sunlight to meet the generation of electricity, the group continued to deepen their understanding of books and internet on how to convert and use solar batteries.

Referring to the "gathering" of equipment for the finishing work of the product, all three recalled memories that perhaps the entire life could not be forgotten. It is a series of days to make friends with shrimp noodles to squeeze every single silver coin, gathering enough money up to ten million dong to buy 4 solar panels ordered from Ho Chi Minh City. Or as the story Minh unleashed the electric bike is his greatest asset to get the engine with speed regulator, scooter, led lights . then assemble this entire component into the dream cyclo. .

"Even buying an old cyclo exceeded our ability at the time, so the three did not hesitate to go to the scrap buying facility to insist on buying a bad cyclo at the price. The cyclo sent to the contest when it was purchased was really too big, we had to give up the painting and repair it for many days, " Minh said happily.

The solar-powered cyclo promises to contribute to tourism development.

Potential tourism products

With a simple structure model because it has not been properly invested, but the solar-powered cyclo of Truong group suddenly won the second prize of the competition organized by the Department of Science and Technology of Da Nang. . At the awards ceremony, experts appreciated the creativity and smooth operation of the product. In particular, the panel of judges praised the process of simulating cyclo operations.

Only from solar panels, light is converted into electricity, generating DC power, which leads to the controller as a device that automatically regulates current from solar cells. and battery current through the power adapter to the motor to help the engine operate.

The biggest advantage apart from the low cost is that the car can operate continuously for 3-4 hours for a full charge.

According to three members participating in the invention, the biggest advantage apart from the low cost (the entire cost ranges from 10-15 million VND / unit) of the product, the car can operate continuously for 3-4 hours. lake for 1 full charge. Even in sunny and sunny conditions, cyclos make sure to operate at full capacity.

Sharing the desire for solar-powered cyclos in the future, Truong said: "Because we believe our products can be applied in practice, we plan to propose them to 2 local localities. Nang, Hoi An and tourism companies in supporting this cyclo production to contribute to diversifying the type of tourism services in the Central market, and the further plan is that we intend to apply This technology is available for many other vehicles such as 3-wheelers for the disabled, street vendors with roofs . ".

Referring to the above model, Mr. Nguyen Xuan Binh, director of Danang Tourism Promotion Center, said: "The solar-powered cyclos are extremely creative and highly feasible. We the proposed city of pilot production of 10 cars and then there will be a specific plan as this is a promising means to contribute to promoting tourism development ".
