The idea of ​​capturing carbon dioxide or converting it to other substances in order to combat climate change is not new. However, simply storing carbon dioxide in a certain compound may lead to its leakage into the environment

In the new study, evidence for additional sources of chemical energy, much stronger and more diverse than methane production, was discovered: a group of organic compounds was found that were oxidized, and this points to many chemical pathways for the existence of potential life in the subsurface ocean of Enceladus, because oxidation helps to release chemical energy.

Before the successful synthesis, it was not clear if it was even possible to create such a molecule and keep it stable long enough to study its structure and its electronic properties.

Using artificial intelligence to reveal magnetism

A simulation that explains the electricity production process: Acceleration secretes recycling molecules (transfers an electron) to a stainless steel electrode (the anode). From there the electrons continue to the platinum electrode (cathode) and on to the sea water molecules. Following an electrochemical reaction with the platinum, the sea water breaks down and forms hydrogen. The passage of electrons from the anode to the cathode creates an electric current, and the hydrogen emitted in the process can be stored and used later to produce additional energy in hydrogen fuel cells. Thanks to the action of photosynthesis, this process is accelerated by exposure to the sun, but it also continues in the absence of light.

Researchers at the Technion have developed a new method for producing electricity from algae in an efficient and environmentally friendly process. The idea, which was born in the mind of doctoral student Yaniv Schlossberg while swimming in the sea, was developed into a prototype by researchers from three faculties at the Technion with a researcher in "Exploring Seas and Lakes for Israel"
