Masdar will be the place that incubates many new energy technologies to scale. That's important. We know how to equip individual buildings with solar panels, heat exchangers, environmental controls, thermal glass and the like. It's not cheap, but we know how to do it. Scaling up to a whole city — even just a whole neighborhood — introduces tremendous complexities and uncertainties. Masdar itself is not going to be the city of the future; it's in an odd place, and it will undoubtedly house mostly wealthy people. What it will be is a thoroughly wired producer of huge amounts of data about how different technologies and processes work separately and as part of complex systems. It is a giant, extremely expensive experiment, much like the first reconnaissance satellite or the first moon landing, and it is likely to have similar technology spillovers.
