I think the tube at first may need a large supply of electrical power but once it has the + charge in about 1/10 of second it should remain like a capacitor, and may need topping off from time to time.

The fuel station can maintain its orbit like the shuttle does.A high volume low velocity ion pump can be built easy. All you need is cheap power to run it, and it comes from solar energy or from that thermal tower.Removable links are very flexable and make good connections. They are very common for comercial generators.

The fuel station, the thing that captures the ions and compresses/liquifies the extremely thin gasses in orbit, will have to be supported by the entire length of cable from the 400km up to the 36,000km counterweight.

Not exactly, it doesn't have to be attached to the structure?

A carbon nonotube structure can also be built from the ground up. It is well within the tensile strength of the molecule.

Aside from the inital cost of solar panels and maintenance on them power comes pretty darn cheap. Also,a new type of electrical power generation is coming out. Basically the sun warms air over a large area of land, and it flows very fast though a tall stack. Figures show it can produce 200 Mws of power.They say it is a reliable energy source near the equator. Both sources are very cheap.

The ion pump is down below at sea level or on land. The weight of it does not have to be supported by the tube. The weight of the ions in the tube at any one time is not that great since it is a ionized gas. The tube diameter is very small.
600Kpa is the theoretical strength for nanotube material. 60kpa is what is projected for the space elevator. We have material now at 120Kpa. BTW the tube could also be built from the ground up to space?????

Are they cells dividing or bacteria reproducing ?[http://marsrovers.jpl.nasa.gov/gallery/all/1/m/046/1M132266947EFF05AMP2987M2M1.HTML]http://marsrovers.jpl.nasa.gov/gallery....M1.HTML

accelerate towards the center of the Earth if it were possible? How fast would an object be traveling by the time it arrived there?

1% rocket failure is pretty bad especially if people are in them.
How many have gone astray, and had to be destroyed? The space elevator also has a counter weight in Geosynchronous orbit, and it is much more massive. The solar farm doesn't have to be as large as it used to be since the panels are alot more smaller and effiecent today.At any given time there is not that much volume of paticles in the tube.,

#988 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-11 14:47:32

Rockets blow up to often. Solar power is free and you can store the energy in batteries for bad days or you can just shut it down for bad days. Also, near the equator the sun almost always shines.The space elevator is to massive but the tube is not.

#990 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-10 20:43:25

I have seen flexable bus bar straps on the generator in the plant for all three phases, it allows for expansion. Perhaps, something like this could work??? Also, on the solar panels I have read that the ones today are alot more effecient. They don't have to be as large anymore. If need be some of the fuel can go to the ion thrusters that keep the station in place or the panels in place.

#991 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-10 20:21:05

Explain more about the tube beam guides???? Can the solar panels at the top be moved to a higher altitude to lower the drag of the atmosphere???

#992 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-10 19:55:30

Solar panels for up there, and the ground based generators can regulate for the right amount of power needed to accelerate the ions to the right altitude.

#993 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-10 19:36:51

It doesn't matter the energy can come from solar panels or a nuke facility.

#994 Re: Unmanned probes » Broken spherele has dark spot inside it???? » 2004-03-10 19:32:59

I bet Mars had only one moon back when life was still existant. The tidal forces could have created the heat for life.
An asteroid or comet broke the moon apart, and knocked it (them) into a different orbit and thus the tidal forces vanished. All we have now are fossils unless they evolved to live under ground now.

How many megawatts will it take to get a flow rate of 24,000 btu per minute of H2 up to the top?

#996 Re: Interplanetary transportation » Physics transfers fuel inside carbon nano tube - fuel into space » 2004-03-10 18:39:36

Ok H2,O2 or N2.

H2 + O2 is a good rocket fuel or it could used for an ion engine.
