Smart solutions for a sustainable world

Published: 14 March 2016

This year's edition of the project course Sustainable Living had ten smart solutions with sustainability as its theme. The aspiring civil engineers showed great creativity combined with technical expertise.

It was a lot of activity in the B-building at campus when third year students at the master engineering programmes Sustainable Energy Engineering and Mechanical Engineering demonstrated their energy smart solutions at the project course Sustainable Living.

Door opener that stores energy

A product that attracted a lot of interest was an automatic door opener. The students have developed a prototype that was mounted on a full-sized door.

– Our hydraulic door opener can store energy to a storage tank from when the door is opened manually and it could be used in all public places. It uses only 10 % of the energy compared to a regular door opener. We have made all the components ourselves and our calculations worked perfectly when it came to opening angle and power. It's been great to work with hydraulics, which was new to us, says Oscar Olofsson who read the MSc Programme Sustainable Energy Engineering.

Effective cutting tool

Jonas Dahlgren reads the third year of the Master of Science Programme in Mechanical Engineering. He explained their cutting tool for foams that his group had devleoped for the company Elgocell.

– We have developed two solutions to cut the insulation details for district heating. Today's method is very costly and inefficient. We have been able to streamline the process with our tools. It has been gratifying to see that our ideas really worked and our clients think our solutions have been perfect. The idea is that next year's group will continue to develop the products and eventually go into production.

Want to beat the world record

Another group showed a large bird-like rail vehicle that will be used in the competition Delsbo Electric on May 28. It's about driving approximately three kilometers on tracks with as little energy usage as possible.

– We aim to win Delsbo Electric and we would also like to beat the current world record. The rules have been changed so therefore we have built a new frame and an aerodynamic carbon fiber body to this year's competition. We will reuse the well-made wheels from last year's vehicle. We are also developing a speed control which is connected to the control system, it will help us to adjust the speed during the race. It's been really fun to work in a project, even though we were ten people it has progressed smoothly, says Zebastian Hallsten who studies the Master of Science Programme in Mechanical Engineering.
