Rocket Stove Workshop in Europe?

Anyone know of such a workshop coming up any time soon? Preference is the Canary Islands or Spain but will consider further afield.
Thanks!

You aren't clear about what kind of workshop. Are you interested in rocket stoves for cooking, rocket mass heaters or what? In case of the latter one, do you mean J-tube or batch box?

Early November there will be a workshop to build a batch box rocket mass heater on Mallorca. If everything is going according to plan the instructor would be me, at the moment I am busy with drawings and stuff.

Oops. I'm interested in building rocket stoves (different sizes) for cooking. At the moment it seems like an indoor version isn't considered safe, so I guess outdoors.
Is the workshop in Majorca using cob or clay? (Is there actually anything else that can be used anyway?)
Would you be interested in running a workshop in the Canaries if there was enough interest?
