On the off chance anybody still cares about the Vapordyne I designed some of the chassis structures and have lots of photos and inside info. Word was it that Lear went through three possible alternative working fluids, Learium A, B, C, and ended up with D-Learium. The program was a non-starter from the beginning. The heat transfer numbers just didn't work and Lear wouldn't hear it, rather listen to his yes-men. Terrible waste of money and talent, but a hell of a lot of hard work and good times. The car was, as of 2010, in the hands of a collector.
