Hydrogen powered things always sounded like a good idea, but it never seemed feasible to me if a large liquid H2 tank needs to be lugged around. Seems like this paste may be on the right track for providing a new form of energy storage/production.
"Fraunhofer researchers have presented a magnesium-based 'Powerpaste' that stores hydrogen energy at 10 times the density of a lithium battery, offering hydrogen fuel cell vehicles the ability to travel further than gasoline-powered ones, and refuel in minutes."
"To produce the paste, magnesium is combined with hydrogen at around 350 °C (662 °F) and five to six times atmospheric pressure to form magnesium hydride. An ester and a metal salt are added to complete the process and form a viscous gray goop that can be loaded into cartridges."
"[C]ompletely stable at temperatures up to 250 °C (482 °F). It carries 10 times the energy of a similar weight in lithium batteries, and substantially more than a 700-bar H2 tank of the same weight."
There are still a lot questions about how efficient this process would it be, how much water is used up in the process, how cost effective could the process become, etc.

Researchers at University Grenoble Alpes in France, have developed a single-quantum-dot heat valve. A device that can help to control the flow of heat in single-quantum-dot junctions.

"New Mercedes Screen Will Span Nearly Entire Width of Car, Regulates With AI" by Interesting Engineering
This episode is a snippet from episode 39 of the That's Cool News podcast.
Daimler's Mercedes-Benz has debuted an impressive new feature for its forthcoming electric luxury sedan: a large, curved screen spanning almost the full width of the car, called the MBUX Hyperscreen. It features an AI algorithm that will better suggest what the user would want at a specific time.
Do you think this will become a normal feature in all cars? Or will it be just for the Luxury EVs?

Water Desalination utilizing a membrane is the most efficient way to create clean drinking water from salt water. Researchers were able to make that process even more efficient with their discovery.
What do you think of this discover? Why isn't desalination more of a thing? Especially with areas that are in a drought or struggling to get clean water.
