The good news: Technologies for zero-carbon aviation are already available today. The bad: It will take years to bring them to market. Ammonia as a drive for more sustainable shipping Shipping leaves a large ecological footprint: the propulsion engines are largely dependent on energy sources that produce climate-damaging CO2 when burnt. In addition to hydrogen and methanol, ammonia is also considered a more climate-friendly substitute fuel. Empa makes eco-cement Cement production is responsible for 9 percent of carbon emissions in Switzerland. Researchers at Empa believe that this can be changed. Even cement production methods that absorb more CO₂ than they emit are on the horizon. Climate scenarios made simple Climate change is too complex for most laypersons to really understand its effects. Researchers have now launched an interactive online platform that offers easily understandable insights into the most important scenarios and models. “We need to become climate positive.” Michael Braungart is the enfant terrible of environmentalists. Be it recycling or climate neutrality – the initiator of the cradle to cradle principle takes a tough stance on conventional approaches. An interview about climate-positive products, tire abrasion, and synthetic plankton. University of Zurich teaches drones tricks Thanks to a navigation algorithm, drones are learning to autonomously perform acrobatic maneuvers. Using simulations, the autonomous aircraft are trained to become faster, more agile, and more efficient. Are electrically driven ships viable? Maritime transport accounts for a significant portion of global CO₂ emissions. Commissioned by a shipping company, researchers at the Swiss Federal Institute of Technology in Zurich (ETH) investigated how this could be changed. They see considerable potential in electric propulsion systems and in hydrogen and ammonia-based fuels. The unrecognized pioneer 60 years ago, Theodore Maiman powered up the very first laser. At that time, however, neither industry nor research saw any practical application for the technology. The story of a major misjudgment. Holidays on Mars? Robots, journeys into space, and flying cars: Which visions out of science fiction movies have become reality? The classics of the genre in a “reality check”. Eye-tracking system facilitates pilot training Researchers at ETH Zurich have developed a system to facilitate pilot training and thus make flying safer. The software uses eye-tracking to reveal perception gaps.
