WHATS WRONG WITH MY VAN DE GRAAF GENERATOR????

I MADE AN OPEN VDG <WITHOUT TUBE>
PLEASE SEE THE IMAGES AND PLEASE PLEASE DIAGNOSE MY  PROBLEM

THE  BLACK THINGS WHICH   LOOK  LIKE  WHEELS  ARENT WHEELS  THEY  ARE  IMMOVABLE  AND NON  ROTATARY.  AND  ARE  USED  JUST TO  GRIP  VDG    ON  THE  FLOOR.


THE  WIRED  WHICH  IS  TAPED  TO THE  FLOOR  PROVIDES  GROUND  CONNECTION.

taping a ground wire to a concrete floor will not provide ground. concrete does not conduct.
You'd be surprised how conductive it actually is, in practice.

so whats next... what should i do ??? remove wire from concrete floor and plug into home's earth(green wire) socket ??
please help i want to see it working....please..
What happens or not?

No connect to a water pipe assuming the are copper.

Your black pulleys may be conductive as the black is often carbon black.

my pully is made of plastic....
Your pulley is likely to be quite conductive, because "black" is often carbon powder.
Black plastic is often conductive - test it with a multimeter.
SAY WHAT'S WRONG !

Why is it not made conventionally, tall, and isolated ?

Explain how you think it should be working. I can't tell what the parts are supposed to be doing so I can't tell you what is wrong with it.

Your apparatus doesn't resemble this pictorial diagram very closely.   Your negative comb should not be grounded.  It should be used to draw sparks from your dome (can?).
I dunno, what's the problem ? Its made wrong to build up charge ? Like, there are good reasons why VdGs are the shape they are ?
