Oh and on NASA's elevator to space, if their that concerned about the price, why doesn't the US gov make use of the ampl hydro thermal power below (enough to power the US for thousands of years with ever increased pop), and build a giant solenoid somewhere to launch space vehicles. We can make amazingly accurate particle accelerators miles long, why not a non-pollutive launch device.

Is your idea supposed to use the Earth's magnetic field to provide propulsion? This won't work. Not only is the Earth's magnetic field too weak, but even if it was strong enough it still wouldn't work on principle. You would be trying to build a giant version of one of those magnetically powered perpetual motion machines that we have to debunk here on a regular basis.

I think your other idea is an electromagnetic accelerator. This has been seriously considered by NASA. The problem with it is the aerodynamic drag. Drag increases as a square of velocity. This limits speeds to around five thousand miles per hour near the Earth's surface. This will not get you anywhere near space as the craft will lose velocity as it rises due to both drag and gravity. Increasing velocity won't help much because the increase in drag will slow it down even faster.

I understand it that the initial blast takes the vast majority of the power. An electromagnetic accelerating launch device would surely allow for smaller fuel loads, in turn wheight/size reduction and more importantly cost. Which is the primary aim of the idea.

The big silly tube however is quite literally that, big and silly, it's a devoid off-shoot of an idea I had when I was young (which wasn't perpetual motion, but still a form of magnetic propulsion. One infact that I made a working prototype of, but it's unfortunate enviromental cosequencies meant it couldn't really be implemented).

Wondering though, the gravitational pull of the moon is not constant, but is strong enough to move water?

The Space Elevator could be paid for by the proceeds of selling abundant clean power provided by space based concentrators. Thus providing the potential to reverse global warming by eliminating almost all human produced greenhouse gas emissions. The same concentrators can be used to provide heat sinks so as not to contribute to global warming.

Where I referred to concentrators, I meant "Solar Concentrators". A one square kilometer mirrored surface can relatively easily be produced in space, the solar winds can provide the propulsion, and having large numbers of such concentrators allows for powering multiple power plants around the world along a prescribed trajectory.
