Are you looking at this as a personal or commercial venture? If this is to be for home usage, one should be required to first gain permission to launch things into space from their local airport, to ensure the flight paths of your launched item and any airborne vehicles don't collide. For a larger usage scale, though, I think this would be a spiffy idea! It would certainly raise interest in space, and we might even end up with several Hubble Telescopes owned by universities and corporations who would allow streaming of somewhat real-time video to PCs everywhere.

for some government to build, not for personel use. Maybe build it high up and near the equator. Does anyone know the speed required to go from sea level to the altitude where they have satelites?

Try Google.com and type in "orbit launch speed". One of the websites that comes back says it's 11.3 km/sec. . . You can find an answer for near everything on the internet.

This is a great idea/dream, but it's not new. Sometimes called a 'railgun' or a 'linear induction motor,' they're currently studied by the military and used in theme-parks to 'launch' the fastest accelerating rollercoaster I've been on. In the 1966 Robert Heinlein book "The Moon is a Harsh Mistress," they are routinely used for spacelaunch, up all of the highest mountains in the world. I do hope this idea comes to fruition someday. Lots of money being spent on it.

"Earth orbital velocity" is 17,500 mph, "Earth escape velocity" is 21,000 mph, "Solar System escape velocity" is 25,000 mph.

It would take much less energy to launch satellites or space probes from the surface of the Moon using a solar-powered linear accelerator.

Satellites (and a lot of other manufactured goods) could be fabricated on the Moon from locally mined material using solar powered processes.

This requires pretty much straightforward engineering; If we expect to support a population of 6 billion plus and still have clean air and water, eventually we'll want to locate most heavy manufacturing on the Moon anyway.

Or just call this "crackpot idea # 11,546..."

hrench u are a c*nt. I spose you have never made any mistakes?

Please ignor this above comment it was for the Aids Tax section comment.

I said your idea was Good. I'm your only Supporter right now. ??? I like to have comments on my ideas--for or against. Why are you being profane and offensive?
