Masdar developmet.Can it work in practice?

This depends on whether Masdar is part of a genuine national devocalization strategy or a one-off green billboard at the airport. When the oil is ‘gone’, what will Masdar produce that can justify the bloated population in the desert metropolis? These questions are not really being addressed - but to me this vision would be more interesting than Masdar as the solar mall it is presented as. What effort avoidance and technology substitution strategy can be used? What are the structural shifts prepared? It is possible and even likely that the planning team has developed these concepts, but visible in the promo material is only a limited and expensive piece of hardware.
