An Introduction to Zero-Point Energy

A common misconception by laymen is that the force is derived from "pushing against" the water/air as in pushing against a wall. In reality, the force is derived from the acceleration of the water/air. The force would be the same in a vacuum for the same amount of water/air accelerated even though there would be no air/water to push against.

The issue:

"The propellor or the jet engine of an aircraft push air backwards to propel the aircraft forward. A ship or boat propellor does the same thing with water. On Earth there is always air or water available to push against. But a rocket in space has nothing to push against, and so it needs to carry propellant to eject in place of air or water."
_________________________________

Perfectly simple point made above.
-- If you are on the ground you can push against it to move.
-- If you are in the water you can push against it to move.
--- If you are in the air you can push against it to move.
--- If you are in space you can't push against it to move, you must eject something away from you.

Now you claim:

"This all started because I took exception to the statement that a "propellor pushes" against the air/water."

As we see above, you can't keep your story straight on ANYthing.

Obviously at a loss of words? Or just at a loss?

Whatever, Mr. c.

Perhaps you remember who wrote this about you.

"Hah! That's rich. "Personal attacks and insults" are your first and last names and inflicting pain is your game. Abuse reports from people with unclean hands are not taken seriously. If you want to be taken seriously on this forum you might think about cleaning up your act."

So you can sling a personal insult then duck and run.

Let's look at an example: Say I'm out in space, with a large rock in my arms, and I throw the rock off in a certain direction. I would of course start moving in the opposite direction. Was I not "pushing" against the rock?

Many anarchist groups and publications used the word "libertarian" instead of "anarchist" to avoid state repression and the negative association of the former term. Libertarian Socialism differentiates itself from "Anarchy" as a movement only in that it specifically focuses on working class organisation and education in order to achieve human emancipation from the fetters of capitalism.

REALLY pitiful, boyo.

'Projecting' your own hangups onto others is one of the more amusing results of your loss of control. Get some help.

[tpaine]

More 'projection' of socialistic rhetoric.
-- How droll.

[Oberon]

If it makes you feel better.

And, what's your answer? Does it constitute pushing or not?

[Regulator]

Most of the force in a low bypass ratio jet engine is transmitted by the pressure on the turbine blades themselves, which of course react out their force on the shaft, which reacts against its bearing, which reacts against the shroud, which reacts against the pylon, which reacts against the airframe...resulting in "we be movin'!"

I have no idea what your point is.
