In 2007, his residence was a hexagonal, shed style mansion he dubbed Westwind, located in Bedford, New Hampshire, just outside Manchester. The house has at least four different levels and is very eclectically conceived, with such things as: hallways resembling mine shafts; 1960s novelty furniture; a collection of vintage wheelchairs; spiral staircases; at least one secret passage; an observation tower; a fully equipped machine shop; and a huge cast iron steam engine which once belonged to Henry Ford (built into the multi-story center atrium of the house) which Kamen is working to convert into a Stirling engine-powered kinetic sculpture. Kamen owns and pilots an Embraer Phenom 300 light jet aircraft and three Enstrom helicopters, including a 280FX, a 480, and a 480B. He regularly commutes to work via his helicopters and had a hangar built into his house. In 2016 he flew as a passenger in a B-2 Spirit bomber at Whiteman AFB, marking the opening of the 2016 FRC World Championship in St. Louis.
