The »Sunglider Smart Uberground Metro« is a multi awarded autonomous, self-sufficient, photo-electrically fuelled public metro-system on level + 1, conceived for medium-sized cities and urban areas called »mezzopolis«. The metro system consists of completely new designed small, autonomous suspension cars, ground movers, cargo movers for parcel & express services, and pedelecs in sharing mode. The entire track is built on wooden pylons in the middle of the road following strictly their course and carries a 6 m wide wooden PV roof generating at least 130% of the energy consumed by the entire metro. By choosing uberground, glulam track construction and disruptive innovations in car design/manufacturing Sunglider reduces the investments radically. Autonomous vehicles and self-supply of free solar energy are reducing the O&M costs drastically. In this way, the Sunglider can offer a subsidy-free zero fare nevertheless generating profits and convince citizens to leave their cars at home for a high frequent and comfortable municipal public transport.
