AR Pioneer Warns That Metaverse Could Make “Reality Disappear”
Posted by Kelvin Dafiaghor in categories: augmented reality, computing, virtual reality
An innovator in early AR systems has a dire prediction: the metaverse could change the fabric of reality as we know it.
Louis Rosenberg, a computer scientist and developer of the first functional AR system at the Air Force Research Laboratory, penned an op-ed in Big Think this weekend that warned the metaverse — an immersive VR and AR world currently being developed by The Company Formerly Known as Facebook — could create what sounds like a real life cyberpunk dystopia.
“I am concerned about the legitimate uses of AR by the powerful platform providers that will control the infrastructure,” Rosenberg wrote in the essay.

Reaction Engines assembles partners for its ammonia aviation project
Posted by Quinn Sena in categories: economics, energy, transportation
The UK’s Reaction Engines has announced a joint venture to create compact, lightweight ammonia reactors it says can be used to decarbonize difficult sectors like shipping and off-grid energy generation – and surprisingly, also aviation.
We’ve written before about ammonia’s potential in the clean transport sector; check out our ammonia clean fuel primer piece from September. Compared against hydrogen, ammonia’s much easier and cheaper to store and transport, and although it only carries about 20 percent as much energy as hydrogen by weight, it carries about 70 percent more energy than liquid H2 by volume.
The weight issue generally rules ammonia out of aviation discussions; at less than half the specific energy of jet fuel it looks less attractive than hydrogen. But hydrogen’s volume issues must also be taken into account. Today’s airliners are built for jet fuel so retro-fitting large-volume long-range hydrogen tanks can mean you lose seats. And anyone who’s flown economy can attest, airlines really like fitting in as many seats as they can.

NVIDIA to Build Earth-2 Supercomputer to See Our Future
Posted by Shubham Ghosh Roy in categories: climatology, robotics/AI, supercomputing, sustainability
NVIDIA plans to build the world’s most powerful AI supercomputer dedicated to predicting climate change, named Earth-2.
The earth is warming. The past seven years are on track to be the seven warmest on record. The emissions of greenhouse gases from human activities are responsible for approximately 1.1°C of average warming since the period 1850–1900.
What we’re experiencing is very different from the global average. We experience extreme weather — historic droughts, unprecedented heatwaves, intense hurricanes, violent storms and catastrophic floods. Climate disasters are the new norm.

How Does China’s Hypersonic Glide Vehicle Work?
Posted by Dan Kummer in category: military
Last month, the global security community was startled by a report that China had twice tested hypersonic weapons over the summer. According to reporting by the Financial Times, this weapons system consists of two parts: a fractional orbital bombardment system (FOBS) and a hypersonic glide vehicle (HGV).
Neither FOBSs nor HGVs are new — but the combination of the two is. Many in the defense community have likened the Chinese hypersonic missile tests to the 1957 launch of Sputnik, a moment when the USSR displayed a technological superiority that stunned the U.S.
