I forget if I've submitted this idea before. It's for a camping tent stove.
A bullet-shaped stove has the flat side of the bullet shape as the front-facing side of the stove, with a transparent frontal hatch to put wood into. The rear-facing side of the stove would be the tapered/pointy end of the
bullet shape, with a propeller-fan mounted on the pointy part. That propeller-fan would be driven thermoelectrically.
The top side of the stove body would be flat, so that pots, pans and kettles can be placed on it for heating/cooking. The stove pipe would of course emerge from this topside of the stove.
But the rest of the stove body would have radiator fins on it for heat exchange with the surrounding air.
The propeller-fan on the back end would blow air around the stove body and its longitudinal radiator fins, for maximum heating efficiency of the air in the tent.
There could also be a thermostat device which could be hung somewhere else in the tent, and be connected (either wirelessly or by wire) to the propeller-fan to speed it up or slow it down, to help regulate the temperature in the tent. We need to have a thermostat-controlled wood stove.
Rocket Mass Heater (probably better than my idea)

The fins will slow down the heating of the pots and kettles, in exchange for warming up the air in the tent. |
|
| |
When the tent is already warm enough, and you just want to boil the kettle, you might want to turn off the fan and even retract the fins. |
|
| |
I don't know how fins can be retracted, as I was imagining most of the stove to be a single-casting. |

However, regarding the vertical stove pipe, I think there could be a further outer cylinder around the lower portion of the stove pipe. Another thermoelectric fan could blow air down through the gap between the cylinder and the stovepipe, for further heat exchange. |
