Many people will push the boundaries in the Metaverse and anonymity fuels it.

A global hunt for spare barrels of crude is underway as sanctions slam Russia, the world’s second largest exporter, following its invasion of Ukraine.
But don’t expect Saudi Arabia to step in to fill the gap, at least for now.
What’s happening: The kingdom could help ease global oil prices, which have spiked to their highest level since 2014. Saudi Arabia has the capacity to raise production by 2 million barrels per day, according to Claudio Galimberti, senior vice president of analysis at Rystad Energy.
Today we can eliminate landfills by incinerating much of the garbage we produce using net-zero-emissions waste-to-energy technologies.
Can hydrogen be a substitute for fossil fuels across the global economy? A report tabled at COP-26 provides a plan to make it so.
Designed by scientists in Germany, the module facade has to be integrated with a building’s technical equipment. The rooms behind the facade can be supplied with solar power and at the same time heated, cooled and ventilated.
Nikola Tesla’s vision of the world is about to become reality.

The material could replace rare metals and lead to more economical production of carbon-neutral fuels.
An electrochemical reaction that splits apart water molecules to produce oxygen is at the heart of multiple approaches aiming to produce alternative fuels for transportation. But this reaction has to be facilitated by a catalyst material, and today’s versions require the use of rare and expensive elements such as iridium, limiting the potential of such fuel production.
Now, researchers at MIT and elsewhere have developed an entirely new type of catalyst material, called a metal hydroxide-organic framework (MHOF), which is made of inexpensive and abundant components. The family of materials allows engineers to precisely tune the catalyst’s structure and composition to the needs of a particular chemical process, and it can then match or exceed the performance of conventional, more expensive catalysts.
“Aside from vastly expanding the geographic coverage of this energy source, the sheer feat of engineering involved deserves a mention. Until now, the deepest artificial point on Earth has been the Kola Superdeep Borehole in Russia. That Soviet-era project reached 12,262 metres (40,230 ft) below ground. Quaise would smash that record if achieving the full potential of 20,000 metres (65,600 ft).” https://www.futuretimeline.net/blog/2022/02/28-geothermal-en…nology.htm
A new drilling technology able to reach depths of 20 km could enable geothermal power to be accessed almost anywhere in the world.
Aluminum is a highly reactive metal that can strip oxygen from water molecules to generate hydrogen gas. Now, researchers at UC Santa Cruz have developed a new cost-effective and effective way to use aluminum’s reactivity to generate clean hydrogen fuel.
In a new study, a team of researchers shows that an easily produced composite of gallium and aluminum creates aluminum nanoparticles that react rapidly with water at room temperature to yield large amounts of hydrogen. According to researchers, the gallium was easily recovered for reuse after the reaction, which yields 90% of the hydrogen that could theoretically be produced from the reaction of all the aluminum in the composite.
Easy aluminum nanoparticles split water and generate hydrogen gas rapidly under ambient conditions.
