A magnetohydrodynamic drive or MHD propulsor is a method for propelling seagoing vessels using only electric and magnetic fields with no moving parts, using magnetohydrodynamics. The working principle involves electrification of the propellant (gas or water) which can then be directed by a magnetic field, pushing the vehicle in the opposite direction. Although some working prototypes exist, MHD drives remain impractical.

Famous quotes containing the word drive:
“we, outlaws on God’s property,
Fling out imagination beyond the skies,
Wishing a tangible good from the unknown.
And likewise death will drive us from the scene
With the great flowering world unbroken yet,
Which we held in idea, a little handful.”
—Richard Eberhart (b. 1904)
