PLANCK SCALE COLLIDER

It is well-known that, collision energy achieved/provided by a particle collider, depends on energy (speed!) provided by the collider & mass of the particle!

It is also well-known that, we need to reach/create Planck energy/scale collisions, to be really able to study/research Quantum-Gravity!
But this seems utterly impossible using any existing particle collider tech!
(Because it would require a collider w/ size of Solar System etc!?)

How about we try the other way?

Instead of trying to increase energy/size of the collider, what if, we increase mass of the particles collided?
What if, instead of trying to collide subatomic particles (or even ions), we collide microscopic objects (w/ masses close to Planck mass)?

Imagine that, we start w/ 2 microscopic objects (spheres/dumbells/donuts/disks/cylinders) kept in mid-vacuum.
(These objects could be permanent magnets and/or +/- static electric charged, to enable controlling their motions using magnetic and/or electric fields.)

Imagine that, we first make those 2 microscopic objects spin, faster & faster, as much as we can, towards relativistic speeds (close to speed of light)!
(Using magnetic and/or electric fields and/or continuous/pulse lasers!)
(So their angular speeds would be max possible!)

Next, we make those 2 microscopic objects move in circular ring(s) (like the LHC ring), faster & faster, as much as we can, towards relativistic speeds (close to speed of light)!
(Using magnetic and/or electric fields and/or continuous/pulse lasers!)
(So their linear speeds would be max possible!)

& next, in the end, we collide those 2 microscopic objects!!!

Now realize that, this kind of collider tech would also have immensely valuable side-benefits:

Imagine, we create just 1 microscopic object w/ max (relativistic) angular & linear speeds
& collide that object w/ stationary objects/plates made of different materials.
(The moving object itself could be made of different materials too.)
How much scientific & technological new data/knowledge that would provide?

Imagine, we create just 1 microscopic object w/ max (relativistic) angular speed.
Realize, it would greatly amplify effects from both Relativity & Quantum Mechanics (more speed=more amplification)!
It would provide a really great way to study true nature/workings of quantum vacuum & spacetime (so Quantum-Gravity)!

Realize, a microscopic object w/ max (relativistic) angular speed would also be storing an immense amount of kinetic energy!
So, such an object would be an incredibly powerful flywheel-based battery!
Imagine, someday, all kinds of chemical batteries replaced w/ microscopic flywheel batteries, which provide immensely more power than any kind of chemical battery
& each such battery can be used for lifetime w/o ever needing replacement!
