Google isn't the only company looking to map out urban skylines ahead of the solar revolution. The folks at MapDwell create surveys similar to Sunroof using technologies developed at MIT, and for more cities to boot. The company has already mapped out New York City, as you can see above, as well as Boulder, Colorado(for growing solar-powered hydroponic kush, obvs), all of the confusingly-named Washington County, Oregon and now San Francisco. "We range irradiation (energy that falls onto the surface) for each city," MapDwell wrote to Engadget. "From zero (dark brown) to maximum or ideal (bright yellow), we call this Solar Access Index or SAI." As such, the southern tip of Manhattan probably isn't the best place for a solar installation. And unfortunately, the service does not also extend to solar-powered food carts.
