About This Video:
I built a thatched hut with an underfloor heating system for the purpose of drying bricks, tiles and pottery faster. I built my standard small 2 x 2 m hut design first to keep the rain off the work site. Then I dug 8 meters of trench, 25 cm wide and deep, zig-zagging through the floor of the hut, while building up the sides with mud made from the excavated soil. When the tunnels were finished, flat stones were laid over the trenches and covered with mud as well to form a flat floor. A fire was lit in the lower entrance of the tunnels and the system drew the smoke through weakly. This was enhanced by building a short chimney at the back. The floor will take time to dry out slowly without cracking. When it is dry, it will be used for drying tiles, bricks and pottery made from a nearby source of clay. This underfloor heating is similar to the Korean "Ondol" or Roman "Hypocaust", both systems involving fire beneath a floor to provide warmth although it is more like the typical ondol with multiple tunnels whereas the hypocaust consists of tiles held up with pillars.

About Primitive Technology:
Primitive technology is a hobby where you build things in the wild completely from scratch using no modern tools or materials. These are the strict rules: If you want a fire, use a fire stick - An axe, pick up a stone and shape it - A hut, build one from trees, mud, rocks etc. The challenge is seeing how far you can go without utilizing modern technology. I do not live in the wild, but enjoy building shelter, tools, and more, only utilizing natural materials.

About This Video:
The previous pulley blower was fixed in place and couldn't be moved due to stakes hammered into the ground that supported the rotor for the blower. This meant that the blower took up room in an already cluttered hut. To make it portable, I tried to lash the stakes to the housing but it would not do so in such a way that the rotor would be centred. So the solution I came up with was to the piece of the ground the stakes were hammered into portable- I simply cast the stakes into an adobe block and it it dry hard. The result was a portable blower that could be shifted out of the way and stored in a corner until needed. I then did an iron smelt with it and it got a similar yield to the original set up.
