Summary

I.      Casimir force:                 

 High precision experimental confirmation with scanning probes:      

 MEM device applications require control of this force (stiction)                         

II.     Repulsion?

 Metamaterials, also invisibility cloaks:     

 Geometry: 

III.   Earnshaw's theorem:             

  No levitation is possible with electrostatic interactions:  

 No levitation is possible with Casimir forces with dielectric composites: 

IV.  Heat radiation:

 Far-field radiation pressure:                                

      Near field repulsion:                      

V.   Propulsive force:

      Contactless heat engine:                          

VI.    Friction of vacuum::
