[Stoves] Open-source adam retort design? NO- se e my comment

....so when you buy his book, and if you make any
improvements to it, you can keep them all to yourself, and
profit from them......

I think the great misunderstanding of "Open source" is too
many people think "free as in beer" rather than "free as in
speech"

There is still nothing stopping the support being
chargeable, and the book completely free.
