Which Products Impressed You Most At NAFEM?

I found a couple of cool ideas that I can see becoming big deals as they get explored further:

Halton introduced some heat recovery systems that use the offeset heat from the cooking line to warm incomming water. They also have a great system for monitoring and saving exhaust air at the hood.

Go3world.com has a perfectly sized ozone generator that makes ordinary tap water into sanitizing fluid many times more effective than clorine bleach and can also be used to rinse raw foods to kill pathogens and extend shelf life. Very "green" technology.
