When I met the Momentum Machine guys here in San Francisco, I was shocked that they were planning to open a restaurant chain instead of licensing the technology out to existing players. Opening restaurants? Making food? Very un-startupy, right?

But it turns out that if anyone can do it, these guys can. The brick-and-mortar restaurant business is massive, bigger than many technology sectors, and prime for disruption with new food and models: there's a $184 billion global fast food market, a $2.1 trillion global market, and just about everybody needs to eat.

This has the potential elements of greatness: serious, hardcore mechanical engineers as founders, with a background in the restaurant industry. More power to John and Alex -- can't wait to try my first one.
