7th Green Technology Challenge on Design and Fabrication

7th Green Technology Challenge on Design and Fabrication

7th Green Technology Challenge on Design and Fabrication of Low-Cost Standby Power Generation System.

College of Science and Technology (CST) in collaboration with Tarayana Foundation (TF) has successfully implemented the project on low-cost standby
power generation system on 2nd June 2019.

This is the 7th year of collaboration between CST and TF. The past projects include:
1. Low-Cost Solar Dryer (the Year 2013)
2. Low-Cost Water Filter (the Year 2014)
3. Low-Cost Insulation Material (the Year 2015)
4. Low-Cost Solar Fencing (the Year 2016)
5. Low-Cost Solar Thermal Heating (the Year 2017)
6. Low-Cost Drip Irrigation (the Year 2018)

As in the past, the preference is given to prototype fabricated using locally available materials and low cost, so that it is affordable to rural communities.

For low-income people, it is important to find appropriate solutions taking into consideration the local economy of the people and local entrepreneurs, as well as the available skills, tools, materials and other resources to create affordable products for improved living conditions and livelihood. 

The purpose of this partnership is to work together to put forward a competition among the Engineering students in the CST to develop the models best suited to Bhutanese conditions. The selected models are replicated and distributed to rural communities for improving their livelihood and the dependence on fossil fuel.

This year, out of 27 proposals from student groups from various programs, only the best five were selected. In two months’ time, the selected groups had to optimize their design and fabricate it.

Two months of hard work finally ended today with groups presenting their design and demonstrating the working model to the jury members. The jury members included experts and engineers from Bhutan Power Corporation Limited, Druk Green Power Corporation Limited, Tarayana Foundation, and CST. Among the five participating groups best three were selected based on their originality, efficiency, affordability, marketability, and materials used. Certificates and cash prizes of Nu. 30,000/-, Nu. 20,000/-, and Nu. 10,000/- were awarded to winning team, 1st Runner-up team and 2nd Runner-up team.

Electric Vehicle

Electric Vehicle

As the country plans to introduce Electric Vehicle in the transport sector, the Centre for Renewable and Sustainable Energy Development under College of Science and Technology is developing sufficient technical knowledge and experience in the field of electromobility.

Three final year undergraduate Electrical Engineering students are working on the modeling and fabrication of a prototype solar electric vehicle and a master’s student is studying the Impact of Electric Vehicles (EVs) on low voltage network stability due to EV charging.

A single motor configuration with a rating of 1000 watts is used in the rear axles of the vehicle to drive the load. The prototype vehicle has a battery bank capacity of 3.36 kWh and a range of 16 km could be achieved.
The concepts of low power drive Electric Vehicle can apply to the airports, high-end resorts, hotels, hospitals, sports stadiums, construction areas, etc.
Through such projects, the Centre for Renewable and Sustainable Energy Development would like to enhance experimental learning, leadership development, built partnership with local industry and encourage creativity, innovation among students.

The JB Solar Solutions, a private enterprise in Phuentsholing supported the students’ works by providing the fabrication tools and workspace during their On the Job training period from December 2018 to January 2019.
