While Yamato-1 proved the viability of magnetohydrodynamic propulsion, the system took up almost the entire ship just for a top speed of eight knots. DARPA aims to do much better.

A Rocket-Based-Combined-Cycle (RBCC) propulsion system employing ducted rocket operation and MHD airbreathing to accelerate the vehicle to Mach 12 in about 4 minutes within earth’s atmosphere, and ...

There were a studies published in 2006 and 2008 that looked at making a fusion rocket using dense plasma focus and air-breathing MHD propulsion. These system proposals would work even if Lawrenceville ...

MALIBU, Calif., April 02, 2025--HRL Laboratories, LLC has demonstrated proof-of-concept on a unique approach to achieve a silent pumping system that replaces traditional mechanical moving parts ...

A radically new propulsion system for boats and submarines appears feasible for development if financial backers can be found, Argonne National Laboratory scientists have concluded after six months… ...

DARPA, the US Defense Advanced Research Projects Agency, is now working on developing a magnet-driven silent water propulsion system – the magnetohydrodynamic (MHD) drive. The primary reason is to ...

Back in the 60's, as a teen, I envisioned a sort of MHD hypersonic propulsion system. A high-energy linear accelerator would partly ionize the air in front of the nose of an aircraft.

Without moving parts, MHD drives should need much less maintenance than existing propulsion systems. "But the real reason everybody's interested in it is that, because there's no moving parts, it ...

HRL Laboratories, LLC has demonstrated proof-of-concept on a unique approach to achieve a silent pumping system that replaces traditional mechanical moving parts with an electric current and a ...

Developers have had some success over the decades demonstrating MHD drive technology on a small scale, but it has been inefficient and impractical for full-scale systems. HRL's new approach to MHD ...
