Tokyo is overbuilt and so by the 1970’s buildings started heading underground.
But psychological problems began to develop in office workers as deprived of sunlight as if working in a mine.
So they invented the Himawari Solar Lighting System, named after the Japanese word for sunflower.
Himawari uses roof mounted tracking fresnel lenses to capture sunlight and fiber-optic “pipe” it underground.
Now that technology is coming to the Lower East Side.
An abandoned Delancey trolley station is being converted into the “Lowline”, a new public park.
This subterranean green space will be one of the first in the world.
It’s slated to open in 2018.
Our enlightened future is now.
