Many industries use heat-intensive processes that generally require the burning of fossil fuels, but a surprising green fuel alternative is emerging in the form of metal powders. Ground very fine, cheap iron powder burns readily at high temperatures, releasing energy as it oxidizes in a process that emits no carbon and produces easily collectable rust, or iron oxide, as its only…

NASA Discovers a Rare Metal Asteroid That’s Worth $10,000 Quadrillion
Iwastheone shares a report from Observer: NASA’s Hubble Space Telescope has discovered a rare, heavy and immensely valuable asteroid called “16 Psyche” in the Solar System’s main asteroid belt between Mars and Jupiter. Asteroid Psyche is located at roughly 230 million miles (370 million kilometers) from Earth and measures 140 miles (226 kilometers) across, about the size of West Virginia. What…
Samsung, Stanford Make a 10,000 PPI Display That Could Lead To ‘Flawless’ VR
Samsung and Stanford University have developed OLED technology that supports resolutions up to 10,000 pixels per inch — “well above what you see in virtually any existing display, let alone what you’d find in a modern VR headset like the Oculus Quest 2,” reports Engadget. From the report: The newOLED tech uses films to emit white light between reflective layers, one…

Tesla Powerwall Rival Seeks To Bring Hydrogen Into Your Home
An anonymous reader quotes a report from Bloomberg: It’s about the size of Tesla Inc.’s Powerwall, but can store up to three times as much energy over a longer period. That’s the promise of a new hydrogen-based energy-storage system for homes and businesses being developed by Australian startup Lavo Hydrogen Technology Ltd. The technology, developed with scientists at the University of…

New Benchmark Shows iPhones Throttle So Hard They Lose Their Edge Over Android
MojoKid writes: Apple has repeatedly asserted its dominance in terms of performance versus competitive mobile platforms. And it has been historically true that, in cross-platform benchmarks, iPhones generally can beat out Android phones in both CPU and GPU (graphics) performance. However, a new benchmark recently released from trusted benchmark suite developer UL Benchmarks sheds light on what could be the iPhone’s…
