The rock-bucket rocket
I got the idea of this stove construction reading a book on how they used to heat medival castels. Offcourse this is a radical downscale of the concept, but the function is somewhat the same. I really like the simplisity of this construction. And I like to think that the “organic” unnsymetrical channels formed by the rocks somehow works better together with the natural flow of gases than channels and chambers… This is neither a bell nor a channel system. It becomes something in between. I know that maintaining a good surfface/weight ratio is important for a good working stove. And I cant think of a more interesting way to obtain that. I rebuilded the...

Solar collectors are almost unheard of, even thoe the climate is mild enough for large solar fractions to cover the heating bill. The picture shows an experimental unit made with only local supplies. We believe we can produse these localy at a resonable cost. As in any design or new construction there are compromises and these criterias are set to guide us in the development. It is possible to end up with a very good system that just a few can afford, we could still might have a great buisness, but then the environmental impact would be small. Our dream is to see these around everywhere around here, and therefore it is crusial that we devlop it under...
