It occurs to me that the most common time to fire a rocket stove is in the evening. This is also the time that we are most likely to watch TV or go on the computer. So for the tech savvy person who wants to keep one eye on the screen while also monitoring the fire, the addition of a camera over the feed tube would be helpful.
I have read quite a bit of discussion about people longing for the ambiance of a fire in the living room. This is not always possible with a RMH. A good view of the wood feed should help to satisfy this need when it is displayed on an 80 inch flat screen.
The TV or computer could be set up to automatically go to the fire camera for a couple seconds each time that the channel is changed or by some timing device.
The fire cam might be used to replace commercials on TV or the screen saver on the computer. I'm sure there's a way to have a little image of the fire displayed constantly on either device.
This might run counter to the idea of a simple wood burning device but if you're reading this, it means you have a computer and probably electricity as well, so you're one $20 web cam away from making this a reality.
A web cam set up this way might make a good marketing tool for the RMH. Not my kind of entertainment but there was an owls nest set up with one of these and they had thousands of viewers even before the eggs hatched.
Maybe he went home and went to bed. And took this tiny ad with him:
