A rapid escape system for buildings including at least one ride unit for a corresponding at least one building occupant to exit via an elevator-type shaft or tube or down the outside of a building at a rapid, predetermined and substantially constant descent velocity. The system includes a lightweight tuned open frame AC linear electromagnetic power generator with one active half fixed to a backpack/ride on which a person or other object/load can be securely fastened, the other active half fixed top to bottom to a tall structure. When coupled magnetically via the air gap and moving they form a tuned AC permanent magnet linear electro-magnetic generator.
