We're very focused on building the hyperloop. And the hyperloop is exactly something we've described as an actual tube with levitation propulsion and a vacuum that essentially vents around sky inside the tube flying at 200,000 feet. That, to us, is the hyperloop, and we're the only company building that.

It would be sad if the expertise built up during the 40 years of the U.S. and Russian manned programmes were allowed to dissipate. But abandoning the shuttle, and committing to new launch vehicles and propulsion systems, is actually a prerequisite for a vibrant manned programme.

Chemical propulsion is obsolete to go anywhere other than the moon. Three days - that's acceptable. But for Mars, we need propulsion technologies to get us there in, say, 60 days - then spend whatever length of time we want to spend and return when we want to come home.

In my writing, I try to combine all my favorite elements of journalism - accuracy, real characters that exist on this planet - with all my favorite elements of literature: a sense of flow, of propulsion, of wanting to read every sentence.

If you stop and think about it, the form of propulsion used today hasn't changed in over a thousand years... since the invention of fireworks by the Chinese.

Edgar Mitchell

We do need different types of propulsion to get to Mars. I wrote one of the first Ph.D. theses on that in the 1960s.

John Moody

The railroad originally was as completely dissociated from steam propulsion as was the ship.

Valerie Harper

Rhoda Morgenstern gave a wonderful impetus and propulsion to my career.

Used to discuss the physical force that makes something move.

Physical Movement

Refers to parts of machinery involved in making objects move.

Machinery Context

Implies an active effort to push or move forward, not passive.

Active Force

Related to the design and operation of engines or motors.

Technical Systems

Often associated with cutting-edge or advanced technology.

Innovative Engineering

Not all engines are for propulsion; some perform other tasks.

Specific to Movement

Used metaphorically to describe a push or progress in abstract areas.

Metaphorical Push

Can describe non-physical concepts, like an idea gaining popularity.

Not Always Physical

 They have the most impressive nervous system in the entire invertebrate world. They have about a half a billion neurons that are distributed throughout their body, such that two-thirds of the neurons are actually in its legs. Now mix this in with camouflaging cells, jet propulsion and a razor-sharp beak, and you have all the makings of a formidable predator.

 but we leave the second stage in this highly elliptical orbit. And at the perigee of the orbit, or the lowest point, it dips into the Earth's atmosphere and basically burns back up. So now we're left with this little kick stage, that white thing on the corner of the screen. It's got its own propulsion system, and we use it to raise and trim the orbit

 That set me on the road to examining biomechanics. So here are the new rules of swimming, if any of you are afraid of swimming, or not good at it. The first is, forget about kicking. Very counterintuitive. So it turns out that propulsion isn't really the problem. Kicking harder doesn't solve the problem

 to attenuate the shock of the limb hitting the ground. Then at mid-stance, the bionic limb outputs high torques and powers to lift the person into the walking stride, comparable to how muscles work in the calf region. This bionic propulsion is very important clinically to patients.
