One of my favorite walks in Paris is along the Promenade Plantee, an old railroad viaduct that has been creatively turned into a a delightful succession of prospects. Inspired by the Promenade, New York has its own version, the Highline. Now a trio of New Yorkers are proposing to turn a 1.5 acre underground trolley terminal in the Lower East Side, abandoned since 1948, into a landscaped park lighted by solar collectors channeling sunlight to fiber optic cables in a system its designer, a former NASA engineer turned architect, calls “remote skylights.”
Kickstarter, which calls itself “the world’s largest funding platform for creative projects” is raising money to build a prototype of  the Delancey Underground project, nicknamed the Lowline.
