I bought 200 raw acres and then a little house and shop about a mile away. In time the raw land was called "the lab" and the property with the house and shop was called "basecamp".

Basecamp came with the shop (sometimes called "the auditorium), a tack room (now called "the little red cabin"), a sort of garage/storage building (now, the office and the garage) and a tiny double wide house (the fisher price house - named because it is one big gob of plastic).

In october of 2013 we built a pebble style rocket mass heater in the house. A beautiful wood box, granite slabs on the top, and stainless steel barrel. Very pretty. Only it worked poorly.

This january, ernie and erica came by and after an hour or two of debate we came up with a design to route the exhaust out the roof instead of the wall. We decided on a design that would sacrifice efficiency for rockety-ness and best chance of working okay with newbies. The new design worked amazingly well. Freakishly well. Too well. The whole thing got too hot! Ernie reduced the size of the wood feed and erica added length to the ducting.

In january, all of the rocks and pea gravel were sitting outside with lots of snow and ice on them. We decided to wait until july or august to finish the project - so that we would be bringing in dry pea gravel and rock.

June is supposed to be one long rain storm that never happened. So during the PDC it was all plenty dry and the student brought the rocks and pea gravel in.

Thanks for that! It's cool to see the hams/prosciutto curing in the background.

Here's hoping for at least one cold(ish) night so we can see how the thing works when we're there in late July. (Yeah, not likely.) It looks marvelous.

The area in front of the house looks so different now that there are giant hugelkultur berms!
