Here's an open source Idea for you.
Suppose you were to create a very
large, say 20 to 30 meters inside diameter, wire mesh tube. And
suppose further that the wire used would be carbon nano tube
conductors coiled around one of the new magnetic materials being
worked on now. Wouldn't what you ended up with be an electromagnetic
tunnel?
Let us then continue speculating what
you might do with this electromagnet tunnel.
Suppose you used however many hot air
lifting bodies it might require to lift this tunnel up to as high as
such atmospheric buoyancy might allow. And once at that altitude you
then powered it up to be the longest electromagnet tunnel ever
created. If you then put a platform in side with its own
electromagnets in it, but with an opposite polarity, wouldn't it be
possible to create your own vertical, linear accelerator?
If you could, and you could get this
thing to hang at at least 20 kilometers, or more, wouldn't you also
be able to launch some very significant payloads into orbit? Or, on
another tact, wouldn't such an electromagnet mesh pipe be the perfect
way to make a space elevator out of?
You materials and engineering gurus out
there need to start thinking about how you might go about making this
mesh. Maybe with some 3D printing on a whole new scale?
