I think it’s a cool engineering experiment but if he really is pursuing this to give green spaces to under served urban communities, then proposing it to be built in LES is fallacy. That area already has parks close by and is inhabited by at least the upper 30% (economically) of the city. What would be spectacular is if the technology they’ve developed for channelling sunlight could be used in subway stations that people already use. Plants and sunlight there would make the lives of millions of commuters across the subway network so much better. This disused trolley place should be made into an urban farm me thinks :)
