 Artificial Intelligence, Data Centers and the Global Race for Electricity By Tonynetone | Engineering & Knowledge We once built television transmitters on mountains and hills to broadcast signals across entire countries. Today, a different kind of infrastructure is spreading across the planet: enormous data centers designed to power artificial intelligence. They are the industrial engines of the digital revolution. Behind every AI conversation, generated image, video or complex calculation, processors work inside buildings that require electricity, cooling, water and increasingly sophisticated connections to national power grids. The cloud is not really in the sky. It has a physical address, and that address is becoming strategically important for the world’s major economies. THE GLOBAL ENERGY RACE According to the International Energy Agency, data centers consumed approximately 485 TWh of electricity worldwide in 2025. The IEA estimates that consumption could approach 950 TWh...

The U.S. National Oceanic and Atmospheric Administration is making a major shift in how it collects weather and environmental data. NOAA has expanded its Commercial Data Program, selecting 14 private-sector companies to supply satellite data across seven different categories. And this is not a short experiment. The new Space-Based Environmental Monitoring contract runs for five years, with another five-year option — potentially taking the program through 2036. The companies will provide data ranging from atmospheric profiles and ocean observations to wildfire imagery, microwave sounding, radar and space-weather measurements. Among the selected companies are Spire Global, PlanetiQ, Tomorrow.io, Muon Space, Hydrosat, ICEYE US, Umbra and others. The interesting part is the direction NOAA is taking. Government satellites are no longer expected to do everything. Instead, NOAA is building a hybrid system, combining government spacecraft with data purchased from commercial satellite constella...

  Long before the United States became a scientific power, a revolution was already taking place in the way humanity understood the Universe. Copernicus moved Earth from the center of the Universe. Kepler discovered that planets move around the Sun in elliptical orbits. Galileo turned the telescope toward the sky and revealed a Universe far more complex than anyone had imagined. Then, in 1687, Isaac Newton explained the motion of planets and other bodies through the universal law of gravity. These discoveries changed more than astronomy. They changed the way educated people thought about order, nature and the world around them. When the American Revolution began, these ideas were already part of intellectual life in the colonies. Benjamin Franklin was interested in science, and John Winthrop, Harvard’s professor of mathematics and natural philosophy, was an accomplished astronomer. In 1761, Winthrop travelled to Newfoundland to observe the transit of Venus across the Sun — one of t...

  Now on: A new study confirms that Mercury’s surface contains far less silica than expected — but beneath the silicon lies an extremely hard crust. Mercury is proving once again that the smallest planet in the Solar System may be one of the most extraordinary. A fresh wave of research has revealed that Mercury’s surface contains far less silica than scientists previously anticipated. Yet, this is merely the opening chapter of a much larger narrative. Beneath that unusual surface rests a remarkably rigid and ancient crust—a geological time capsule preserving the violent echoes of the planet’s infancy. Researchers estimate that Mercury’s surface contains roughly 37 percent silicon dioxide ($\text{SiO}_2$) by mass, a figure potentially plunging up to 25 percent lower than historical estimates. This chemical discrepancy is far more than a mere footnote in planetary science; the abundance of silica packed into surface rocks offers profound clues about cataclysmic events unfolding deep ...

  Niobium. The Hidden Metal Behind Modern Technology Most people have never heard of niobium . Yet this remarkable element quietly supports many of the technologies that define modern life. From powerful MRI scanners and particle accelerators to stronger steel for bridges and vehicles, niobium has become one of the most valuable materials in advanced engineering. With atomic number 41 , niobium is a silvery gray transition metal that combines exceptional strength, corrosion resistance, and superconducting properties. These unique characteristics make it indispensable in industries ranging from medicine and aerospace to energy and electronics. Basic Facts Symbol: Nb Atomic Number: 41 Atomic Mass: 92.90638 u Category: Transition Metal Discovered: 1801 State at Room Temperature: Solid Melting Point: 2,468 °C Boiling Point: 4,742 °C Density: 8.57 g/cm³ A Long Journey to Its Name The history of niobium is one of the most interesting naming stories in chemistry. In 1801, English...
