Umm, actually you have your orbital mechanics mixed up. You have to speed
Venus up in order to get it to shift to a higher orbit, an orbit in which it
will have a lower velocity ( assuming a stable orbit) but a higher energy
state.

BTW hello all, I was busy for awhile on a project.

I'm certainly no more materialistic than the next guy, but to live in this
world one needs certain material things like food, shelter, and a college
fund for ones daughter. So who amongst you may judge me for doing what is
necessary to meet those needs?

Suppose you joined Mars and Venus together with a big elastic band?

It breaks.

Probably. A tether with controlled drag and winches along it's length
would
be better. I was thinking more in terms of a "star trek tractor beam" as a
first approximation.

Or if infinitely elastic, sooner or later, it will be stretched close
to/into the Sun. *Then* it breaks.

You can swing it out of the way of the Sun (and the Earth) above the
plane.
Actually as the orbits are slightly inclined you might not even need to.

And that's ignoring what the rotations and atmospheres of both
worlds, are doing to this thing.

Venus's rotation is quite slow, and Mars is lighter. I never said it would
be easy...

However you only (!) have to slow Venus by about 5.2 km/sec and move it 41
Gm away to put Venus at 1AU from the Sun.

It's just a wild thought for now. I don't think you could get Venus to
more
than a ~136 Gm (Earth's orbit is 149 Gm, Venus 108 Gm mean) orbit that way
anyway, and even that needs lots of trickery, but I've got more
calculations
and thinking to do.
