What Is MHD Propulsion?
Often, when we think of moving vessels, we imagine burning fuel, propellers, and turbines. But magnetohydrodynamics – MHD – tells a different, revolutionary story. Instead of combustion, MHD uses electromagnetic force to push through fluids, requiring no moving parts.
Here’s how it works:
- Run an electric current through a conducting fluid – this could be ionized plasma, liquid metal, or even seawater.
- Apply a strong magnetic field perpendicular to the current.
- The result is the Lorentz force, creating thrust that propels the craft forward silently and efficiently.
Real-World Applications and History
The idea isn’t sci-fi – it’s grounded in research and prototypes:
- 1938–1940: Hungarian engineer Béla Karlovitz pioneered MHD power generation, earning a U.S. patent in 1940.
Wikipedia - 1960s–70s: Early propulsion models emerged – including a 1966 MHD submersible test in Santa Barbara and continued work in Japan and Russia. Challenges included building strong enough magnetic fields.
wiki.edu.vnWikipedia - 1992: The Yamato-1, built by Mitsubishi, became the first functional MHD ship. Propelled by superconducting magnets using ionized seawater, it reached 15 km/h – proof of concept but limited by speed and efficiency.

MHD on the Horizon
Today’s technology has advanced, breathing new life into MHD:
- DARPA’s PUMP Program (2023) is actively developing silent, efficient MHD undersea drives using high-temperature superconductors – pushing toward practical military prototypes.
Naval TechnologyPopular Mechanics - Tokamak Energy (2024) is aiding in magnet innovation with powerful, durable high-temperature superconducting magnets – ideal for fusion and MHD systems.
Financial Times - Modern benefits include lower noise, reduced environmental impact, virtually no mechanical wear – and the potential to revolutionize marine and even atmospheric or space travel.

The UFO Hidden Connection
While there are inside ties linking MHD propulsion to UFO phenomena – suggesting ionized plasma fields for hover and stealth – No confirmed evidence in unclassified documents links MHD directly to recovered craft.
Why It Matters Now
- Silent, Emission-Free Travel: MHD could redefine naval and civilian transport.
- Engineering Without Moving Parts: Fewer breakdowns and longevity built into the design.
- Energy & Efficiency Potential: With better magnets and materials, MHD drives can become competitive with traditional propulsion.
- Doors to the Future: A bridge between ancient legends of silent flight and tomorrow’s starcraft.
Closing Thought:
Magnetohydrodynamic propulsion isn’t just theoretical – it’s been built, tested, and is moving closer to practical use. When the currents of plasma and magnets align, movement becomes not just propulsion, but a dance with energy itself.
