It’s complex, and many categories need to take action – politicians, companies and researchers. They all met at the 8th International Sustainability Transitions conference at Chalmers in June 2017.</b></p>​​Nearly all the countries in the world have subscribed to the vision of a sustainable future. But how do we achieve it? What obstacles are in the way? What roles should various players have, and how do we make the transition go fast enough? <br /><br />At the 8th International Sustainability Transitions Conference, hosted by Chalmers, scientists, politicians, organisations, and industry representatives addressed these questions. Watch the video above to hear some prominent voices from the conference.<br /><br />Read more:<br /><a href="/en/areas-of-advance/energy/joint_initiatives/Pages/Chalmers-Initiative-in-Innovation-and-Sustainability-Transitions.aspx">Sustainability transitions research at Chalmers</a><br /><a href="">8th International Sustainability Transitions Conference</a><br /><br />Video: Torgil Störner and Ingela RoosThu, 22 Jun 2017 00:00:00 +0200 video with Åsa Haglund on blue lasers<p><b>​Åsa Haglund, associate professor at the Photonics Laboratory at MC2, talks on her research on blue lasers in a new video published by the Swedish Foundation for Strategic Research (SSF). SSF is also funding Åsa Haglund&#39;s research as well.</b></p><p>​Blue light – that is what Åsa Haglund her researchers at Chalmers aim to create. In 2014, the Nobel Prize in physics was awarded to the invention of blue light emitting diodes used as bright, low energy sources of white light, a good replacement for the old energy guzzling incandescent light bulbs. However, Åsa Haglund wants to take it one step further.</p> <p>&quot;What we a<span></span>re interested in is whether it is possible to use laser-based lightning instead of LED lamps. LED lamps are very good, they are very energy efficient when you are not trying to get a lot of light from them. But you do want quite a lot of light from a lamp , so in order to get more light from the LED lamp you have to add a lot more current. However, in doing so, the efficiency drops dramatically, perhaps as much as from 80 percent to 40 percent&quot;, Åsa Haglund says in the video from SSF.<br /><br />Åsa Haglund is a member of the SSF career development programme for future research leaders, and funded with 6 MSEK for 2014-2019. Hear her tell more about her research, and future applications of the blue laser light, in the six minute film.</p>Fri, 09 Jun 2017 09:00:00 +0200 cars negotiating their way through the intersection<p><b>​In the video above we see three cars heading for an intersection, at a speed of 50 km/h, and passing the intersection almost simultaneously. The self-driving cars are initially on a collision course, but negotiate with each other and adjust their speeds to avoid collisions and maximize the traffic flow.</b></p>​ <br />Intersections are particularly challenging and dangerous in today’s traffic system. A large number of cars need to share the same crossing and, to avoid accidents, traffic lights, signs and rules are necessary. Unfortunately, this causes the traffic flow to slow down and queues to arise, and fuel consumption to increase. With communicating self-driving vehicles there is a great potential for improvement and many problems could be alleviated.<br /><br />The demonstration shown in the video is conducted at the AstaZero test track by a group of researchers from Chalmers. When the self-driving vehicles approach the intersection, they communicate with the other vehicles and a joint decision is taken on how to cross the intersection in an optimal way.<br /><br />&quot;Today's traffic system is both accident-prone and inefficient. Often the vehicles are forced to halt unnecessary. With our method, we can automatically find the most energy efficient and safe solution. For example, a smaller vehicle would accelerate through the intersection in order to avoid slowing down a truck”, says Robert Hult, researcher at the Electrical Engineering Department.<br /><br />The decision-making process is very fast and is repeated as the cars approach the intersection to adapt to unforeseen events. The demonstration is developed to promote efficient traffic flow and the method is scalable and can be applied to more than three cars.<br /><br />What does it feel like sitting in a self-driving car passing another car with such small margins?<br />&quot;The passenger's experience must of course be taken into account, and although the comfort was very good, the crossing felt a little tight at first. After a couple of times, however, it became quite natural&quot;, says Mario Zanon, researcher at the Department of Electrical Engineering.<br /><br />The research involves several research groups at Chalmers, and is partly performed within the research project Copplar. Copplar stands for Campus Shuttle cooperative perception and planning platform, which aims to develop a self-driving vehicle for city traffic, regardless of weather conditions, which can be run between Chalmers two campuses Johanneberg and Lindholmen.<br /> <br /><br /><strong>The results have been published:</strong><br /><a href="" target="_blank">Primal decomposition of the optimal coordination of vehicles at traffic intersections</a><br />Robert Hult; Mario Zanon; Sébastien Gros; Paolo Falcone, Chalmers University of Technology<br /><br /><a href="" target="_blank">An Asynchronous Algorithm for Optimal Coordination at Traffic Intersections</a><br />Mario Zanon; Sébastien Gros; Paolo Falcone; Henk Wymeersch, Chalmers University of Technology<br /> <br /><br />The research has been funded by VR, the Swedish Research Council, FFI, Strategic Vehicle Research and Innovation, Vinnova grant no 2015-03075, the research project Copplar, and Chalmers Area of Advance Transport.

By using a composite with added graphene, the hull is made stronger and lighter. Hydrofoils are added to lift the boat, decreasing drag and allowing greater speeds. After tests performed in SSPAs towing tank, the dinghy was ready to be tried out at sea for the first time.</b></p>​A relatively new occurrence within the sailing world is to mount hydrofoils on small sailing dinghies. Chalmers and SSPA wanted the challenge to do this on “the world´s least advanced sailboat” – the optimist dinghy. The main question and problem for the students and the researchers of this project has been: can an optimist foil and how will this be done? <br /> <br />The optimist dinghy has, since it was conceived in 1947, become one of the world’s most popular sailing dinghies, with over 150 000 boats registered. The boat, only 2.3 metres in length and with a sail area of 3.3 square metres, is normally limited to speeds below 4 knots. <br /> <br />However, by building the boat in carbon fiber and graphene, and fitting it with hydrofoils lifting the hull out of the water, the hydrodynamic resistance can be reduced dramatically. <br /> <br />The hydrofoils, constructed and tested at SSPA, allowed the optimist dinghy to sail as fast as the wind in the recently conducted sea trials, achieving a maximum boat speed of 12 knots in only 12 knots of wind.<br /><br />Watch a video about <a href="">the premiere of the foiling optimist</a><br /><br /><strong>For more information, please contact:</strong><br />Christian Finnsgård, +46- 31 772 9156, mobile +46-730729156, <a href=""></a>Fri, 07 Apr 2017 00:00:00 +0200 interviewing Nobel Prize Winner Sir James Fraser Stoddart<p><b>​VIDEO: Two undergraduate students, Ellen and Vincent, got the opportunity to meet the 2016 Nobel Laureate  in chemistry, Sir James Fraser Stoddart at his visit to Chalmers.</b></p><p>​<span>Their talk was about dedication and passion for research, and anecdotes from an impressive career in the field of chemistry.<br /> <br />PARTICIPANTS: Sir James Fraser Stoddart Nobel laureate in Chemistry in 2016, Chalmers students Ellen Augustsson and Vincent Ssenteza<span style="display:inline-block"></span><span style="display:inline-block"></span></span></p>Fri, 16 Dec 2016 15:00:00 +0100 low energy light to high energy light<p><b>​​Damir Dzebo defends his PhD- thesis September 28.
