                            a electrostatic machine which uses a moving belt to accumulate very high voltage s on a hollow metal globe
                                                            
                                                     
                        
                                                
                        
                        
                            a large conducting sphere which acquires a charge as electrons are scuffed off of a rotating belt as it moves past sharp elongated prongs inside the sphere
