Water heater or sci-fi bomb


Well, it's not nearly as cool as the Maker Faire in Austin this week, but this electric water heater was sure a looker. That turbine-looking device is the flow sensor. It provides the computer some idea of the flow rate of the water so it knows how hard to pulse the heating elements hidden in those sexy stainless steel tubes. Of course, the timer is there so you know how long you have to get off the ship before the core goes critical and you need to be at least two parsecs from the resultant thermonuclear explosion.
