Minesto aims to offer clean, dependable, and cost-effective ocean-based power solutions through its Dragon-class tidal power plants.
Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All these photocatalysts require high energy light for excitation and their oxidizing power has not yet been fully exploited. Furthermore, precious and hence expensive metals are the decisive ingredients in most cases.
A team of researchers headed by Professor Katja Heinze of Johannes Gutenberg University Mainz (JGU) has now developed a new molecular system based on the element manganese. Manganese, as opposed to precious metals, is the third most abundant metal after iron and titanium and hence widely available and very cheap. The study is published in the journal Nature Chemistry.
A magnitude 5.7 earthquake struck the world’s largest active volcano on Friday — Mauna Loa on the Big Island of Hawaii — knocking items off shelves and cutting power in a nearby town but not immediately prompting reports of serious damage.
The earthquake, which didn’t cause a tsunami and which the U.S. Geological Survey initially reported as magnitude 6.3, was centered on Mauna Loa’s southern flank at a depth of 23 miles, 1.3 miles southwest of Pahala.
Discover how BMW and Toyota are accelerating the shift to hydrogen-powered vehicles, revolutionizing the automotive industry.
From the article: As much as 55,000 tons (50,000 metric tons) of hydrogen could lurk in the reservoir beneath the mine — enough to sustain the high flow rate for 238 years, according to the study.
A portion of ancient oceanic crust that sits atop Albania and hosts one of the largest chromium mines on Earth also contains a huge hydrogen reservoir, offering a potential source of clean energy.
Ammonia-oxidizing microorganisms (AOM) use ammonia for energy and account for the annual oxidation of approximately 2.3 trillion kilograms of nitrogen in soil, freshwater, the subsurface and man-made ecosystems.
But one major question that has remained unanswered for decades is how different AOM species coexist in the same environment: do they compete for ammonia or instead use other alternative compounds for their energy needs?
New research by Lawrence Livermore National Laboratory (LLNL), the University of Oklahoma and other collaborators found an answer that significantly changes the understanding of ammonia oxidation, a critical component of the global nitrogen cycle. The research appears in Nature Microbiology.
Chinese researchers have reportedly developed a high-powered microwave weapon cooled by a Stirling engine.
Chinese scientists have reportedly used the cooling properties of the Stirling engine to increase the power of a high-power microwave weapon.

Many researchers now believe that within the next few decades, power plants will provide carbon-free electricity from thermonuclear fusion.
EV charging network Electrify America will soon offer the public an EV charging experience safe from the elements, where drivers can pull in, plug in, and chill out while their vehicle replenishes. This flagship indoor charging station kicks off a potential future in which you don’t have to wait in your car or outside while you charge… It also has complimentary Wi-Fi.
Electrify America is one of the largest open DC fast charging networks in the US that is investing billions into expanding EV infrastructure to support the growing number of zero-emissions vehicles hitting roads.
Outside of the Tesla Supercharger network, Electrify America is easily the most prominent and recognizable name in its respective space, expanding cleaner energy alternatives like solar farms to support its growing number of EV charging stations.
