It only looks like an MTA bus...it's really a self-contained home-away-from-home!
Once parked, EVERYTHING electric inside is solar-powered (15 cubic foot refrigerator, electric stove, microwave, rice cooker, coffee maker, track lighting - can you say "conspicuous consumers of solar"??).
Plus, it has really cool gadgets like windows that open outward with hydraulic lifts, a marine toilet with macerator, and storage doors assisted with hydraulics...and, pretty soon it will be PURPLE!!!
