Have you ever read The Culture series by Ian M. Banks?

If you like sci fi give it a read, there's some eye-opening ideas there about what the endgame for society with highly advanced AI will be.

Advanced AI will be able to do almost anything that humans don't want to do and do it much better than humans, so this will usher in an advanced post-scarcity age which allows for much less restrictive legal and societal structures.

University of Adelaide’s Professor Shizhang Qiao and Associate Professor Yao Zheng from the School of Chemical Engineering led an international team that successfully split seawater without pre-treatment to produce green hydrogen.

Professor Qiao said, “We have split natural seawater into oxygen and hydrogen with nearly 100 per cent efficiency, to produce green hydrogen by electrolysis, using a non-precious and cheap catalyst in a commercial electrolyser.”

The team published their research in the journal Nature Energy.

A typical non-precious catalyst is cobalt oxide with chromium oxide on its surface.

Associate Professor Zheng explained, “We used seawater as a feedstock without the need for any pre-treatment processes like reverse osmosis desolation, purification, or alkalization. The performance of a commercial electrolyser with our catalysts running in seawater is close to the performance of platinum/iridium catalysts running in a feedstock of highly purified deionized water.

Professor Zheng added, “Current electrolysers are operated with highly purified water electrolyte. Increased demand for hydrogen to partially or totally replace energy generated by fossil fuels will significantly increase scarcity of increasingly limited freshwater resources.”

"Researchers say they may have discovered the solution to a problem that has long hindered progress with a novel form of plasma propulsion that could one day carry humans to distant planets, and potentially launch a new era of space exploration.

The helicon double-layer thruster (HDLT) is a prototype plasma thruster propulsion system that works by injecting gas into an open-ended source tube, where radio frequency AC power produced by an antenna surrounding it electromagnetically ionizes the gas. Within this highly charged plasma, a low-frequency electromagnetic helicon wave is excited by the antenna’s electromagnetic field, further heating the plasma."
