Yes, the steam would make the water move in many directions but the
point is that it's not RUNNING uphill. It's being propelled uphill.

True. However steam, water vapor is less dense than air and tends to
rise, causing thunderstorms, where rising moist air can carry liquid
water upward. The steam runs uphill, like a balloon, but the liquid
water does not, it is carried.

Uh... hot air rises. How can water vapor be less dense than air?

You ****ing assholes have no idea of science.

oscillation velocity of a photon in a gravitational free fall even though

Does it not just get bluer falling in gravity. The higher the
frequency, the more energy a photon has.

"Photons climbing out of a gravitating object become less energetic. This
loss of energy is known as a "redshifting", as photons in the visible
spectrum would appear more red. Similarly, photons falling into a
gravitational field become more energetic and exhibit a blueshifting. The
observed energy E_observed at radius r_observed of a photon emitted at
radius r_emitted with energy E_emitted is [7] "

http://en.wikipedia.org/wiki/Density_of_air

"The addition of water vapor to air (making the air humid) reduces the
density of the air, which may at first appear contrary to logic.
This occurs because the molecular mass of water (18) is less than the
molecular mass of air (around 29). For any gas, at a given temperature and
pressure, the number of molecules present is constant for a particular
volume. So when water molecules (vapor) are introduced to the air, the
number of air molecules must reduce by the same number in a given volume,
without the pressure or temperature increasing. Hence the mass per unit
volume of the gas (its density) decreases."



Who is the one lacking in science knowledge?

What force do you think does work against gravity to allow aeroplanes

Thrust from the engine, of course.

Nope. How many aircraft do you think are capable of vertical takeoff?

Handwaving. The only possible source for the increase in the
gravitational potential energy is the engines. Wings impart no energy
that is not their function. There is drag that goes with lift, and
engines have to impart energy to overcome it. I have had a commercial
pilots license for more than forty years, if you want more handwaving.

The question was not "where does the energy come from?". The question
was "what force ... does work against gravity ...?" and (save for a
trivially small downwards component) that ain't thrust.

My own aircraft has a take off mass of 370kg and no thrust whatsoever,
and yet I can get it to go up.

Not in still air.

A glider can climb in still air. Not for very long, normally, but it
can certainly climb. No thrust.

Or do you have a balloon. Those burners suck fuel like an engine, the
chief concern is having a source of energy same as with an engine.

How do you think helium balloons work?

Why wouldn't it accellerate indefinitely with no friction anywhere in

Kelvin-Froude actuator disk theory is your friend.

Not needed. The assumption of no friction, remember. The energy has to
go somewhere. Do extremely simple arithmetic.

The momentum has to go somewhere consistently as well. "Simple" might
work, but "simplistic" won't. Sorry.

You have me there. However, how many do you think are in use? I would
guess somewhere between zero and none. For all practical purposes they
don't exist.

Myself, I like to fly small hydrogen balloons. Dry cleaner bags. You
dissolve aluminum chips in lye to get the hydrogen.

Same as a boat, displacement.

What about the Goodyear fleet?

Really fun if you can get them to ignite at altitude.

Doesn't mean they don't work.

I have a scheme for tapping into the power of the rotating earth. I even
built an apparatus that worked for several years. Michael Faraday built a
small scale device working on the same principle. It is not perpertual
motion or any crackpot scheme. It does slow down the rotation of the earth a
little and causes local weather changes (on a very small scale).

Bill

If what you say is TRUE, then the rest of us should make it our business
to KILL you and everyone who KNOWS about your device.........

You have invented a GLOBAL Disaster, as if you pull energy from the
Earths Rotational Momentum, then the Earth will obviously STOP Spinning,
and Life as we know it will CEASE. Your Device is kill us ALL, and
therefore is actually WORSE, for humanity, than GLOBAL WARMING......

Let us all start the GLOBAL Angular Momentum Crisis Insitute to deal
with this MONUMENTAL Crisis, in the making. Maybe I can even win the
Nobel Peace Prize, for this idea......

Me who wonders just how stupid humanity really is......

:You people are ****ing nuts. You don't have any idea of physics.

Some guy named Einstein won a Nobel prize for proving that. He didn't
have any idea about physics either, the prize was in chemistry.
