For those in the curious, assuming a dyson sphere of 1au radius, which we can't, and an exact sphere, which we can't, and a perfectly flat track around the entire sphere, which we can't, we get the following invalid, but impressive, numbers.

The hypothetical track would be

1,512,706,032 Miles

long, and at 120mph, take

12,605,883.6 Hours

or

525245 Days

or

75035 Weeks

or

1443 Years

over a thousand _years_ to drive the sphere. That's some beef, there!

Edit: fixed diameter/radius confusion. A dyson sphere of 1au _diameter_ would be excitingly hot.
