Like from my understanding the casimir effect is dependent on conductive materials due to virtual particles. So what would stop us from using thin, one direction conductive (aka diodes) light enough materials in a thin enough structure where the casimir effect would overcome any other force, in order to harness that energy to our benefits (whether energy wise,flight for small devices,or improved spatial orientation,to name a few ideas that come to mind) by stacking multiple layers of such thin plates so the force could increase?
Like is it the lack of a material to check all the necessary conditions, the lack of technology that could give us such precise,thin multilayered yet close structure, some misunderstanding I have with the casimir effect, or is it something else?
