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.

  • Congress Could Pave The Way For Tesla's Robotaxi Dreams
    January 8, 2026, 8:10 PM EST. Congress could clear a path for Tesla's Cybercab by raising a key regulatory cap. A House hearing on the Motor Vehicle Modernization Act would, if passed, lift the annual production limit for vehicles not bound by Federal Motor Vehicle Safety Standards from 2,500 to 90,000. The change would also apply to other autonomous-vehicle providers, such as Zoox. Even with more permissive rules, Tesla still faces software challenges before scaling, including rights to the Cybercab name and the need to install new charging infrastructure since the car lacks a charge port. In short, regulatory relief may unlock production, but software, branding, and charging logistics remain hurdles for a true robotaxi rollout.
