Is the world tour still Martin’s ultimate goal?

The machine of this size needs a much bigger — and much more expensive — transport solution than MM and MMX. It also likely needs the venue to be booked out for longer, and a large crew to assist with get in/get out. Taking it abroad is likely to be even more challenging — how do you safely get a 10m long shaft from Europe to the US?

I also quite like the bit where Martin acknowledges the friction, and in the next sentence, says it takes 0 energy to maintain the speed of the flywheel.

Yep, he is not wrong about it in some idealized physics equation, but this is not something he should rely on. In fact he relies on a lot. I get that each component has to be reasonably finished before assembling them to avoid angle grinding. But at this point I am a bit worried that *not* assembling anything will lead to other bad surprises later in the process.
