What should be done with all the carbon dioxide?

Capturing carbon dioxide (CO₂) from the atmosphere and storing it either in recycled concrete aggregate or in geological reservoirs in Iceland is not only technically feasible, but also has a positive carbon footprint. These are the findings of a pilot project lead by ETH Zurich and commissioned by the Swiss confederation.

Replicating the structure of bird feathers

Modelled on nature: researchers have developed a new material that replicates the structure responsible for the blue feathers of the North American song bird, among many other birds. It also has other striking advantages.

Autonomous excavator constructs a six-metre-high dry-stone wall

ETH Zurich researchers taught an autonomous excavator to construct dry stone walls itself using boulders weighing several tonnes and demolition debris.

New technology can collect CO₂ from a truck's exhaust pipe

EPFL spin-off Qaptis has developed a system that can cut freight trucks’ carbon emissions by up to 90%. The company just installed a prototype of its technology at a freight carrier based in Tolochenaz in order to conduct pilot tests locally.

Printed robots with bones, ligaments, and tendons

For the first time, researchers have succeeded in printing a robotic hand with bones, ligaments and tendons made of different polymers using a new laser scanning technique.

3D printed reactor core makes solar fuel production more efficient

Using a new 3D printing technique, researchers at ETH Zurich have developed special ceramic structures for a solar reactor. Initial experimental testing show that these structures can boost the production yield of solar fuels.
