I wonder if they could suspend the corkscrew style ones into certain alleyways and passively feed into the grid. The row homes can certainly create a wind tunnel. No idea if this is remotely feasible or a practical way to achieve anything of value.

I made two rectangles out of scrap 2 x4s and attached some wheels underneath. Cross piece to connect the two boxes at the proper width for the table legs. The drafting table sits atop the risers with two pieces of small 1/4 inch scrap on each rectangle to keep the table from shifting around. Had bought a children's drafting table when I was in art school because it was that much cheaper and I was an older student with a mortgage to pay. Works great, still use it despite having acquired a standard size drafting table. The wheels ended up being a great decision.
