If we can rearrange the vacuum we can get clean, limitless zero-point energy without fuels.

Maybe just two spinning donuts (one copper and one semi-conductor), in a vaccum, magnetically floated and pressured together along the spin axis by bookending with magnets. A wire along spin axis carries current.

Casimir effect catalyses dragging charges across the disc surfaces.

pedant. because it is a unit.

but one thing I think is interesting is you can further categorize primes.

FTA is unique factorization. but those factors can be re-arranged (most FTA text says ignoring order).

considering order is interesting. then you can class primes by how many ways they can be rearranged.

in that case, including 1 in the factorization once is interesting, since it differentiates between squares

n x n

and cubes

n x n x n

which can not be rearranged anyway unless you include 1 (not as a 'prime' but as the unit in the factorization)

1 x n x n, n x 1 x n, n x n x 1

3 ways.

And cubes, 4 ways.

From that point of view, primes are simply the numbers that can only be rearranged 2 ways.

1 x p, and p x 1

This is a very interesting avenue.

Just the definition.

a number with no factors beside 1 and itself, excluding zero

1 does not meet that definition, since 1 is already counted, the other factor needs to be different.
