mini solar chimney for micro power generation

i'm fascinated with the solar chimney concept for electric power generation. i'd like to build a small, fabric-based model, see if it might be able to provide enough power to charge a couple of car batteries. does the mefi hivemind want to help me brainstorm?

there's some pretty decent video here
of a large scale project in australia (not yet constructed).
i'd like to design something which could be built from locally available materials, nothing too complex.
a smallish tethered hot air balloon might serve to support the structure.
a long tapered cylinder made from fabric (fireproof at the bottom) would be suspended from the balloon and anchored to the ground.
at the top of the cylinder we need some kind of turbine. hot air exiting might also feed the balloon. at the base we'd have a small wood fire.
i'd love to hear from any and all mefites, with or without experience in power generation/off grid/ballooning.
if it works, i think we should call it a montgo.
