I was imagining how one could design a newer, more efficient city then the cities we have right now and I came up with a fairly basic design concept that I later Googled and found I was not the first. That concept was that of a snowflake. But why design a new city? Currently modern cities are chaotic, messy, disorganized and generally ridden with issues because of poor planning or the failing of the settlers to imagine how huge these cities would become and how poor the infrastructure would be as the population exploded. It will be easier and cheaper to build new cities from the ground up then to refit our current cities to be better, more energy efficient for example. The basic idea of the snowflake is the main roads are the arms of the snowflake, with smaller streets as the interconnecting segments and various buildings in the in between spaces, a central governmental/administrative area in the center, followed by utilities, 'offices,' recreational, and residential going outward. However, the snowflake can keep expanding in a repeating pattern if necessary, or we can build another city. Power grids would be subterranean, and based on clean sources like nuclear, solar, tidal if your near an ocean, and potentially chemiosmosis power I think its called (Bacteria and viruses used to generate power via kinetic energy from walking or tapping, such as in your phone or under the sidewalk) So how would you setup a geometric city?
