What if it is neagatvly charged H2 used as the electrode? Would the H2 corrode?

#1078 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-04 21:28:24

Would a negative electrode at the top collect the positive ones from below?

#1079 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-04 21:18:48

Enough energy to heat a gallon of water to boiling, for a measly half a paperclip worth of propellant.
So you can ionize it. Either positve or negative? Suppose positive going in, and at the top negative coming out? At the top you can place a negatve electrode to collect the positive ions from below.

How much energy is involved in giving the H2 or He a charge + or -?? Does it depend on the volume of H2 or He?

#1083 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-04 19:37:21

Wow Just got home. What if they are all going the same direction up the tube?

#1084 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-04 00:53:07

Ok then, a micro world statement for you. If any free molecule of H2 escapes to space then all free molecules of H2 will escape to space.

#1085 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-03 21:27:30

I guess Bernoulli was wrong then. Planes don't fly either.
H2 is not bound to this Earth as it is to Jupiter because Jupiter has a greater gravity well.
Did you run the model on the 100% H2 or He in the Earths atmosphere without solar heat added? What happens?

#1086 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-03 20:59:33

No matter how you look at it if you change the pressure you change the velocity no matter how big or small the molecule is.

Even cutting down the tubes height from 36,000km to 400km is only a tiny improvement, given that gravity will cause the vast majority of the gas to "pool" at lower altitudes. Again, an order of magnetude improvement of an extremely small value is still useless.

Did you run the model on the 100% H2 or He in the Earths atmosphere without solar heat added? Since H2 is the universes greatest element in mass you would think there would be more of it here. Look at Jupiter its gravity is so great that H2 is collected there in great masses.

Here is one example in the USA. There are many examples world wide.

1: Pressure does not effectively determine the speed of any individual gas molecule, only temperature does this. Pressure is simply the the density of a gas in a given volume, not how fast the individual molecules travel, only their number.

   Not according to Bernulli's principle. If one increases the pressure of a gas on one side of a venturi then the molecules will accelerate through the narrow passage way.

2: Unless a gas molecule can reach speeds at aproximatly 11,000m/s, then the molecule will not reach the top of the tube. Hydrogen, the "fastest" gas there is, the majority does not signifigantly top 3,000m/s at reasonable temperatures. However, a VERY small number of molecules do gain this velocity due to momentum transferred from other molecules, but this number is so small that it will accomplish nothing.

   This same principle governs how high H2/He will rise in Earth's atmosphere, and since it only has to reach ~100km and not 36,000km against the force of gravity to the geostationary tube end, much more gas per-area can escape. Even then, the amount of gas that escapes is quite small by area things considerd. Furthermore, our atmosphere has a HUGE surface area, so even the tiny loss of gas over a small area is magnified orders of magnetude... since the tube will be pretty small, it will not have this luxury either since its cross-section is small.

Since the gas only has to reach ~400km this is where the end of the tube will be placed in space about as high as the shuttles orbit.The counter balance for the structure can be further away. If it even needs one since it will be filled with lighter gasses.

#1089 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-03 18:57:38

Simply put, if it escapes Earths gravity then it will also escape the tube. If the pecentage of H2 is near 100% entering the tube then it will be near 100% as it exits the tube. The differential of pressure is more than enough to overcome the gravity effect on H2 or He. If it was not then no H2 or He would never escape the atmosphere at all. How about giving the Earth 100% H2 in the atmosphere in your model with no solar energy, and see what happens to it?

#1090 Re: Life on Mars » What if the Mössbauer shows the spheres are Hemati » 2004-03-03 17:22:36

They plan on placing the M?ssbauer instrument on a pile of the sphereles. What if it shows they are hematite? Would this mean the organisims through diagenisis have become hematite?

#1091 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-03 16:58:15

So what you are saying is the gas would have to be compressed so much it would have to become a liquid before it would have any chance of coming out the end of the tube in space, and the tube would break before that would happen. I ain't bying that idea  because the H2, and He make it out of the atmosphere in a gas state and not the liquid state to begin with.

They look like geysers to me. Very similar to the flowing mud pits out west in Yellowstone park.Except much much larger!!!

#1093 Re: Life on Mars » Could these be hatching from the spheres?? » 2004-03-03 13:16:25

Food for thought???
Could they still exist deeper below the surface??

#1094 Re: Life on Mars » Spheres are concreations. Are they are hematite? » 2004-03-03 13:14:07

Possibly, or are some fossils on earth made of hematite? Could these have been hatching out of the spheres?

#1095 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-03 12:50:46

I agree about the tiny amount. What if you added extra tons & tons of H2 or He in the atmosphere in your model. would the net amount be more that escapes the atmosphere??

#1096 Re: Interplanetary transportation » How far off are we to conquering gravity? » 2004-03-03 02:36:56

Can we replicate that force to send objects to space? Also,It will take millions of years to exhaust all the Earths H2 to space or even longer if comets add water to the Earth at the same time.

#1098 Re: Interplanetary transportation » How far off are we to conquering gravity? » 2004-03-03 02:18:04

Hydrogen and Helium defy gravity. Both elements make it through our atmosphere every day to space.

#1099 Re: Life on Mars » Spheres are concreations. Are they are hematite? » 2004-03-03 02:00:02

What if the spectrometer finds out they are hematite?? Could they then be fossils? Lots of water is involved we now know.

#1100 Re: Unmanned probes » Broken spherele has dark spot inside it???? » 2004-03-03 01:55:44

What if the spheres are Hematite? Today they called them concreations because of the interaction with water.Now that we know the bedrock has very high percentage of sulfur, and it was drenched in water at somepoint in time,is it possible those spheres are fossilized? Does Hematite take over minerals through digenisis?
