This means that they only lost 3% of the energy they used versus 73% for combustion propulsion.

Find yourself a high-quality snorkel valve with a panoramic view and comfortable water-tight seal to pair with flexible, responsive fins that support your legs with the proper propulsion.

The advanced reactor was loaded with decades of enriched uranium fuel that made steam for propulsion and electrical power so we could disappear under the waves indefinitely without returning to port.

BRP is a global leader in the world of powersports vehicles, propulsion systems, and boats.

With the MEV-1′s electric thruster replacing the aging satellite’s spent chemical propulsion, the hardware can add another five years to the vehicle’s lifespan.

It is adopting technology—in rocket propulsion, composite construction, and aerodynamic refinements—already in use elsewhere.

These mostly focus on propulsion and transport, but 4M is a different concept.

It certainly cannot sail under its own power, as 80 percent of the electricity generated on board is used for propulsion.

It seemed to lie flush with the ground; there was no visible means of either support or propulsion.

They are about fifty feet long, fish-shaped, heavily armored and have some unknown method of propulsion.

No one talks of the liver secreting bile, or of the heart acting for the propulsion of the blood, by instinct.

Gauthier proposed to use that engine in the propulsion of paddle-wheels placed at the side of the vessel.

The screw was found to possess many advantages over the paddle-wheel as an instrument for ship-propulsion.
