I'm trying to build a simple Van De Graaff generator, for the first time.
The problem is quite obvious - the current generated is zero.
Can somebody help to find what is wrong?
The column is a typical sewer pipe, axles are aluminum bars, electric screwdriver acts for motor.
The upper roller is glass textolite in free-spin on aluminum bar, the belt is doorframe rubber band. The materials seems to fit the purpose - when the roller was rubbed against the belt, it got enough charge to lift some pieces of paper.
The lower roller is a duct tape construct fixed on an aluminum bar the screwdriver is connected to.
Brush wires are typical copper wires, the sphere is a party balloon rolled in a layer of aluminum foil and a layer of duct tape, also tried a dried pepsi can and two pots.
The weather is bad, but the attempts are made in an air-conditioned room.
There are neither sparks, nor current indication on an ampermeter, with or without the sphere.
The pictures of the thing:

Any advice where to look for problems, or is anything obviously wrong?
