Rosch taking orders on OU Bouyancy device.

it's compressed outside of the container, and piped in at the bottom.  does not have to additionally travel through the water.
  I did forget surface tension of the water.

What about the column of water above the air that needs to be lifted up to make way for the air? does it just magically float upward?

If you'd like to propose a free energy machine that is powered by the steaming pile of crap that equates to this analysis then I'd probably be willing to invest.

Sure, the masses do not change significantly but the distance between them does. The last time I looked the force due to gravity was equal to (G *m1 * m2)/r^2 . If you alter the distance between the two masses then the gravitational potential changes as the inverse square of the distance.

Also mass is NOT proportional to gravity. A 1 kg mass on earth is the same as a 1kg mass on  the moon or floating in space somewhere in the universe.

The quantity you are referring to is weight or mass multiplied by the acceleration due to gravity.

Might i suggest you go and have a peak at exactly what happens to the tide's around the world before you start calling other peoples opinions a steaming pile of crap. Then also have a look into fluid balancing harmonics in a rotating device-such as the earth. Take a flywheel and cut a small piece out of it that would represent our ship,and glue that small piece a little further out toward the outer perimeter of the flywheel. Now spin that flywheel in the vacuum of space and tell me that it will slow down quicker than it would if that piece was placed back to where it came from.

Your fancy numbers(G *m1 * m2)/r^2) mean nothing in this instant,and are only relevant when the forces are confined to earth-->which in this case,they are not,and have no meaning at all in space where there is no gravity-->which is the medium our planet resides in.

So who is talking a steaming pile of crap now.

well see that's why I'm asking how does the pressure relate to that?  I mean... if the pressure is more, it's going to displace... the whole point in needing the excessive pressure over 1atm is the weight of the water... but the weight of the water turns out to be a very small percentage of 1atm additional... so at 1.053atm it can displace 21 inches of water easily.


(increasing the pipe size at this time does improve additional gain... to go 0.5inch which is 2.6x to 3inch is from 4.86x and an 8 inch pipe is 7.5x... increasing the length doesn't help (the height of water is computed based on the pipe diameter) but then requires much more pressure.. and almost 2HP to compress...)


so at 8 inches the height is 10.5 feet, and the pressure required is 1.32atm minimum... (10.5feet is 3.2m and 10m is +1 atm)

[MarkE]

if  nRT ln(V₂/V₁ ) is the work to compress the gas to greater than the pressure at the bottom... what more work is required than that? Oh I see... once the gas does start flowing, then its pressure becomes less and you have to apply more force to maintain the pressure ( or have compressed a larger volume to a greater pressure )...

okay.  So if I compress 5 times the volume of air to twice the required additional pressure it's still less work than the total bouyance force.

and bouyancy is ( mass_displaced - mass_displacing ) * G.  (the air weighs something so should be subtracted from the mass displaced...)

... So, having an understanding of these basic physics principles where is the discontinuity? 


How does one relate the force required to displace X with pressure?  Or.. why does it matter how much water is moved?  The pressure is enough to overcome the additional weight of the water.. and if it was under a solid plunger and moved the whole body of water, why does moving that water imply any more work than it took to presureize the gas?




input... (compress 5x the required air; twice the required exess pressure @ height of 14 buckets)

2.366602913

Work (ft-lb)

(edit: or even 4x the volume and 4x the pressure, so if I take 1 unit of volume out it's still 75% of the increased pressure... something; ya it's some differential
edit2: hmmm ya that needs to be looked at it's probably the missing work)

output...(14 buckets)

36.61705229

lift force (ft-lb/sec^2)

Your premise fails right when you start conflating force and energy.

Astounding!  this is "free energy" at it's best. Not content to produce power from steaming bullshit you multiply the effect by digging an even bigger hole for the theory to reside in.

My advice is to stop digging before the fall becomes painful.
