Welcome.  We are Ernie and Erica Wisner (mostly Erica, writing this).  We like a lot of different things.  We have a website at, which introduces us and our work.

If you like what you see here, please sign up for updates on this blog (right sidebar), or sign up for our general newsletter.
Or just leave a nice comment (we love that!) and come back when you feel like it.

You may know us from our work on rocket mass heaters and related earth-and-fire technology.  If you want to catch new developments in this field, only, you could sign up for our RMH Builder e-mail list

Ernie also has a long-standing commitment to Pacific fisheries conservation and maritime heritage, including boat-building, ocean ecology, and taking care of our beloved coastal communities. The long-term goal is to build a sailing catamaran as a live-aboard platform for education, research, and coastal disaster relief. We have a dedicated mailing list for that, "The Passages Project."

We are currently based on a snowy, semi-arid mountain in the Okanogan Highlands, about as non-maritime a climate as you care to find.  We are part of a local permaculture study group, and sometimes help out our neighbors with their farms, herds, and fire protection.

We also regularly participate on the forums at
