[MCN] any interest in rocket mass heaters? Wanna see several in action?

[paul wheaton]

When I first heard about rocket mass heaters, I didn't believe it.
But it did get my curiosity up enough to go see one in action.  And
now I have more than a dozen (7 rocket mass heaters, 2 rocket heaters
and 5 other rockety things).

If there is enough interest from people in missoula to come see these,
I will set up a quickie event and have folks over.
