i cannot find any information on this. i would like to know if it is possible to have a small rocket stove in my room and vent it out my window safely? im planning on selling my home in a couple of years and dont want anything permanent. just something to reduce the ammount of power we use to heat. another dumb question i cant find the answer to; do you even need to vent a rocket stove? if it burns so clean isnt it safe to burn indoors without any ventilation? any advice would be greatly appreciated.

You definitely need to vent the stove. It burns very, very cleanly (when it works properly and has proper fuel), but that does not mean it is a safe idea to have the exhaust filling your living space.

There is quite a bit of discussion in this forum on the subject of how to vent your rocket stove, and why for most applications you really need a chimney that extends above the roof peak of the structure the stove is in.
(see, for example, http://www.permies.com/t/29601/rocket-stoves/sending-exhaust-wall-roof )

In some applications it does work to exhaust horizontally, but it is a limited set of applications with very specific parameters.

Peter Ellis : Perhaps you remember seeing the movie Apollo 13 about the 3 astronauts whose trip to the moon had to be aborted after an ''Onboard Accident' ?!
It's most famous line is - " Houston, we have a problem !" On top of major problems that limited power and oxygen the device that was supposed to scrub
excess Carbon Dioxide CO2 out of the air was malfunctioning and the Crew of Apollo 13 could have died of CO2 poisoning, fallen asleep and never woke up !

If you haven't seen it it had Tom Hanks in it and got an Academy Award (I Think)!!

The best I can explain horizontal venting is to say that In very small houses sub 800 sq. ft.purposely built around the heater and not installed as an afterthought
it can be a workable option, much forethought into planning the build is necessary as is a stable climate with winds that are stable and not shifting during your
entire heating season, An Air port within 5 miles of your house could give you a good idea of what their weather,climate, wind directions and speed for any period
in its history, and that data could be all wrong for your location ! I hope this helps and is timely ! Big AL !
