This reminds me of some vernacular thermally active surfaces that’s adopted by people in the rural part of northern China. Explained by Moe in his another writing, this design is called Chinese Kang, a thermally active bed. “In this system, the living space of the house was a few feet bove the level of the kitchen and fireplace in an adjacent room.” Hot air is channelled horizontally from the fire. There are slots built under the finished floor from the fireplace to and exterior chimney. The floor slab is made of concrete coated with clay. And on top of this are layers of oiled paper and floor mats. When heat warms up the concrete, the space above is heated up as well mainly due to radiant effect. the bed surface is then heated up as well and transfer heat to human body, mainly through conduction. Here, radiation is the main starting process of heat transfer, followed by more direct conduction. The following diagram explains this system.

I have been also trying to integrate this as a passive solar heating thermal mass! I've done the winter sun calculations (nanaimo, BC) and it's looking very possible!
ps. I'm a little new to this concept :S

I've been thinking that maybe a water tank for thermal mass would work best? then it could be drained when I want to hit the road again... but.. water brings a whole new element of over heating the thermal mass I would think? uncharted territory for me!
Aaron Emberson wrote:good points! I've always found myself to be a bit nomadic.. Perhaps that's why I've focused on the transportation factor. I've been contemplating sizing down even more then this for more ease of heating/transportation/and general cost. But the main issue I keep coming back to is heating! for instance.. could i heat the cap/cover of a truck with a renewable heat source without having a large cost? would a mini pocket rocket work? is there even a possibility of a functional thermal mass in a space that small?
I've been thinking about insulating a very very small area so it could be heated very simply without fossil fuels.. perhaps electricity (battery bank and solar panels?) would be the best solution?
Without subsidies, chem-ag food costs four times more than organic. Or this tiny ad:Rocket mass heaters in greenhouses can be tricky - these plans make them easy: Wet Tolerant Rocket Mass Heater in a Greenhouse Plans
