accelerate H2 atoms or He atoms?
Offline
Wow, the third thread about this tube concept thingie...
A laser will not push a gas like a solar sail because the gas is not reflective like a metal. So, the gas will actually absorb the energy and get hot, real hot if it is arranged properly. With a million watts of laser power, I imagine it could get hot enough to decompose carbon structures or melt metal before the atoms will attain a high speed... say, escape velocity.

So how fast will the H2 or He molecule go if it is hit directly from behind with this powerfull laser?

This depends on some factors, principly the wavelength of the laser, and if the hydrogen atom would reradiate the photon or not.

The first place to start would be a quick detour to quantum mechanics and to determine the energy of the photons, then back to the kinetic theory of gasses to estimate the change in velocity of the molecule by the addition of that energy, which would set an upper limit anyway for the velocity change.

A linear photon collision from behind should accelerate the H2 or He molecule. A linear photon collision from behind into a electron sould send that electron off at near the speed of light while the photon breaks apart into two photons.

Ummmmm no... On the microscale, the macroworld rules don't apply first of all, and the electron won't go "zooming off" unless the atom becomes ionized... are you talking about what goes on inside a laser matrix?
Oh, and I would like to note that in a gas with multiple molecules, the "speed" is a distribution, and simply dumping more energy doesn't generally increase the fastest moving molecules, but rather makes the slower ones move faster. The fastest hydrogen molecules don't top 3000m/s generally... Keywords: Maxwell Distribution, Boltzmann Distribution, Kinetic Theory of Gasses.

Actually, I think the photon bounces off the electron while the electron gets excited and emits a photon. I would think if the atom is constantly bombarded by photons from behind it will continue to accelerate beyond the 3000m/s threshold.

Nope, it absorbs the photon as electromagnetic energy, the momentum is not nessesarrily transferred to the electron, and not particularly to the molecule as a whole either.
And say you did get it going lots faster by random absorption... congratulations, you just melted your tube... provided you can make enough high-energy photons to accelerate lots of hydrogen molecules.

In fact, I would take a breif introductory look at quantum mechanics of light before you go on any more.

What charge would the molecules take on?
Offline
Unless the electron is stripped from the atom, none. It would remain neuteral.
I strongly reccomend looking into a good web page or short text into quantum theory of light and such, since the rules that apply are completly different than those of macroworld physics.

Why should I do that when I have you here?

Because on the other threads, your macroworld aproach could at least be modified to describe how the microworld works, but on the quantum level the rules don't even vaugely resemble eachother. Your concepts wouldn't relate at all... heck, i'm not a physical chemist or a particle physicist, I only know the basics.

What threads are you talking about? Can you give me some links? :band: :band: :band:

The other ones you started concerning your "pipeline to the sky" of course.
These might be a good starting point...

Noteably, the momentum of the photon is not transferred to the atom entirely.
