After breakfast, I went back to last night's site of the shows, as I wanted to get some better shots of the Dutchtub and meet up with some of the students, when I bumped into Floris, who was cleaning up around the tubs, and refilling them with fresh water. Turns out he is the man who invented it, Floris is in product development and he came up with this idea about 4 years ago ( I'm sure he said 2002 or 2003 )

And he also works with a guy called Dick Van Hoff who made this Stone Stove, a combustion heater with a steel frame to which pieces of concrete fit together to make this stone stove, making it more mobile

I want one, and the tub as well ofcourse

A better look at the tubs

Floris explained how it functions, and it oculdn't be simpler, the water sits in the coils, the heat pushes it out through the top, and thenormal pressure of the water , forces it into to bottom pipe, so simple, makes me want it even more
