Scientists from the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Dresden made the sludgy gray paste, which heats hydrogen with magnesium and stabilizers so the hydrogen can be stored in cartridges even at room temperature. That s it in the photo above.
What results is a stable medium that its makers say is 10 times more energy-dense than lithium-ion batteries,
“When it comes time to release the energy, a plunger mechanism extrudes the paste into a chamber where it reacts with water to release hydrogen at a dynamically controlled rate, which then feeds a fuel cell to create electrical power with which to run an EV powertrain or other device. Part of the paste s impressive energy density comes from the fact that half of the hydrogen released comes from the water it reacts with.”

What Is Liquid Nitrogen, and What Is It Used For?
Nitrogen gas makes up roughly 78 percent of Earth s atmosphere by volume, according to the Royal Society of Chemistry. The element, discovered in 1772 by Daniel Rutherford, is a critical building block of all life on Earth and plays a key role in plant growth. When cooled to -320 degrees Fahrenheit, the gas turns into an ultra-chilly liquid.
Polish professors Zygmunt Wróblewski and Karol Olszewski became the first to successfully liquify nitrogen in 1883. Just 15 years later, the British scientist James Dewar developed a storage canister for the substance, which served as a prototype for modern LN2 storage containers.

The premise sounds scary, but knowing the odds will help scientists who work on these projects.
Self-teaching AI already exists and can teach itself things programmers don’t “fully understand.”
In a new study, researchers from Germany’s Max Planck Institute for Human Development say they’ve shown that an artificial intelligence in the category known as “superintelligent” would be impossible for humans to contain with competing software.
That . doesn’t sound promising. But are we really all doomed to bow down to our sentient AI overlords?
➡
Berlin’s Institute for Human Development studies how humans learn and how we subsequently build and teach machines to learn. A superintelligent AI is one that exceeds human intelligence and can teach itself new things beyond human grasp. It’s this phenomenon that causes a great deal of thought and research.
