Using a Kaluza-Klein framework, we consider a relativistic fluid whose proj
ection yields the supersymmetric non-relativistic Chaplygin gas introduced
by Bergner-Jackiw-Polychronakos and by Hoppe, The conserved (super)charges
of the Chaplygin gas are obtained as the projection of those arising in the
extended model. (C) 2001 Elsevier Science B.V. All rights reserved.
