At the Cool Product Expo, entrepreneurs show off everything from electric cars to personalized 3D printers to a scent production machine.
STANFORD, Calif. -- One of the tricks of building a successful company is identifying new markets. So while you might never have known you wanted a digital scent delivery system, a startup called Scent Sciences thinks that's exactly what you desire.
Scent Sciences and dozens of other companies flocked to Stanford University yesterday for the annual Cool Product Expo, a showcase of some of the, well, coolest gadgets, toys, electriccars, and oddball beauty items around. Among the most interesting items on display were 3D Systems' Cube, a personal 3D printer that costs just $1,300 and is being touted as extremely easy for just about anyone to use.
