Hydropower delivers renewable electricity, but comes with massive fish mortality – a global dilemma that can only be addressed by true compromises, says Luiz Silva, and outlines how to find them.

Oceans absorb carbon dioxide from the atmosphere through microscopic algae that carry out photosynthesis and then sink to the deep sea when they die. This sinking enhances the degradation processes, as ETH researchers have now discovered.

A keen mountaineer, Manfred Hunziker has conquered well over 6,500 peaks. As an ETH graduate in electrical engineering, he followed a career shaped by the dizzying rise of computer technology.

The 23-metre-high tower made of 3D-printed columns is to become a cultural site in Mulegns, a village on the Julier Pass with just 16 inhabitants. The structure is being planned by ETH architects and engineers. Construction is scheduled to start in spring 2022 with robots printing the tower’s components on site.

ETH Zurich and the Paul Scherrer Institute (PSI) establish a joint centre for the development of quantum computers. Its aim is to advance the realization of quantum computers based on both ion traps and superconducting components. ETH Zurich provides 32 million francs for this centre, which will host around 30 researchers.  

An 80-metre-high skyscraper made of wood is soon to be built in Zug. A pioneering project for which basic research is being carried out in the construction hall on the Hönggerberg.

Over the course of the EU project “FIThydro”, research and industry partners studied the ecological impact of hydropower plants. ETH Zurich’s Laboratory of Hydraulics, Hydrology and Glaciology (VAW) has developed a protection and guidance system that can help migratory fish to safely bypass hydropower turbines.

Carbon-neutral aviation is possible, but in future, aircraft are likely to continue to be powered by fossil fuels. The CO₂ they emit must be systematically stored underground. This is the most economical of various approaches that ETH researchers have compared in detail.

Coral reefs are in acute danger of disappearing due to climate change. An artist and a marine biologist have taken up the challenge of rebuilding the reefs by harnessing the power of 3D printers.

On 13 and 14 November 2020, some 60 teams from all over the world will compete at CYBATHLON 2020. It’s the high point that pilot Stefan Poth has been waiting for – postponed by months due to the pandemic. At last, he can show what he can achieve when wearing a leg prosthesis.

Fibre-optic cables are emerging as a valuable tool for geoscientists and glaciologists. They offer a relatively inexpensive way of measuring even the tiniest glacial earthquakes – plus they can also be used to obtain more accurate images of the geological subsurface in earthquake-prone megacities.

Swissloop, the team of students developing hyperloop pods, took advantage of the break imposed by the coronavirus to improve the technology even further. Yesterday they unveiled their “research pod”.
