All your objects are really small.
Try multiplying all tour values by 1000. This will not affect the aspect 
of your objects, but can get rid of accuracy problems as well as isues 
regarding distances that are to small.
That way,
cylinder {< -0.0052500000, 0.0000000000, 0.0000000000 >, < 0.0052500000,
0.0000000000, 0.0000000000 >, 0.0015000000 texture {pigment {color Red 
transmit
0.5} finish { phong 1 }}}

becomes this :
cylinder {< -5.25, 0, 0 >, < 5.25,0, 0 >, 1.5 texture {pigment {color 
Red transmit
0.5} finish { phong 1 }}}
