IBM’s 4,000-Qubit Quantum Supercomputer Could Change Computing Foreve

IBM plans a 4,000+ qubit quantum supercomputer by 2025, achieved by interconnecting three 1,386-qubit Kookaburra chips to form a 4,158-qubit system. The Quantum System Two modular platform, debuted in 2023, is designed to host multiple chips and features a cryogenic refrigerator and

Asteroid Minerals: Mining C-Type, S-Type & M-Type Space Rocks Worth Trillions

C-type asteroids make up over 75% of known asteroids and are rich in water bound in clay minerals and organics, enabling in-space fuel and life-support resources. S-type asteroids account for about 17% of known asteroids and contain iron, nickel, cobalt, plus trace

Deep-Water Wind Revolution: Floating Turbines Set to Transform Offshore Energy

Floating wind turbines are offshore wind generators mounted on buoyant platforms tethered to the seabed with mooring lines, allowing deployment in waters far deeper than 60 meters where fixed-bottom foundations aren’t feasible. About 80% of the world’s offshore wind potential lies in

Satellites Powered by Water? The Revolutionary Propellant Changing Spaceflight

Water propulsion for satellites can use steam propulsion (resistojet), electrolysis to hydrogen and oxygen for combustion, or water-plasma/ion thrusters for high-ISP propulsion. Momentus Space’s Vigoride uses a Microwave Electrothermal Thruster (MET) that microwaves water with solar power to boil it into plasma
