Near the Los Angeles produce mart area (blocks and blocks of different businesses) we wired up an oyster bar. There were at least two lunch trucks during the say, rotating among different trucks.

One of them was a modified big rig with a short freight container on the back of it. Was that overkill? Nope. It also had a custom Italian pizza oven in the back! It's one of those wood-fired ovens with the little shiny ceramic squares on it, about four feet in diameter. The owner says the rig was necessary because the damn thing is HEAVY.

But running it off the heat of a hydrogen-run engine? Smart.
