Atop the helium-filled dirigible superstructure are translucent solar collectors and rainwater catchment facilities which provide power and irrigation for the parks and fields below. By virtue of its airborne nature and possession of vast green plantings, the Light Park will provide a powerful source of clean air back to the city which it floats above. The airborne nature is also, sadly, a source of concern given the current climate of the world, with the abundance of terrorism and those who mean to do others harm. It is unfortunate and disappointing for contemporary humanity that such a forward-looking, optimistic proposal- which is more than likely, within the grasps of current technology- must be viewed in this dark light of ‘what if’.
