think it would be safe to add a few million more.

Right you are - I missed that point.

A 100 GeV charged particle (electron OR proton) has a radius of
curvature in the galactic field (1 microgauss avgerage) of about 3
billion km (3 light-hours). No way they're crossing galactic distances
anytime soon- probably billions, rather than millions, of years...
Neutrinos, sure-

to be an even better alternative and we are
watching wire development progress with that extremely light material
many times stronger than steel.

Much as I'd like to have some ultraconductor wire to play with, I'm not
convinced that Ultrqaconducting Magnetic Energy Storage will replace
batteries. Magnetic fields create a pressure equal to the energy
density- and therefore require a strong (read heavy and expensive)

For cooling, you'd want a well-insulated flat plate solar collector.
This would provide a large surface for radiating heat into the sky at a
wide range of angles. You wouldn't want a low-E surface on the panel,
because this prevents radiative cooling. My first experiment would be a
I have ...attempted to estimate how fast the filament will heat up.
From the description on JLN's web page, I estimate the filament has a
mass of about 1.2g, and would require about 200 Joules to heat from an
average temperature of ~700K to the operating temperature of 2000K.

Why not just dispense with the ramps altogether, and instead mount the
"ball" on the rim of a bicycle-size wheel- using the smoothest bearings
you can find, and very lightweight construction? That way the "return"
is free, with less friction than you've got now; just position the
magnets along
