Ok then, I am going to attempt to develop a research plan for my offgrid tiny house on wheels. There is a lot of technology that has been ignored and left unplayed with and I think it’s time we started playing with it.
Firstly, let me reintroduce wood-gasification (http://www.build-a-gasifier.com/fema-gasifier-plans/). You tell me why it would be a bad idea to replace gasoline (non-renewable) with wood and other biomass (very renewable). The FEMA supplied design was intended to be easy to set up and get going in the event of a catastrophic fuel shortage. Sounds like a good place to start playing. I saw Rocket City Rednecks hook a gasifier up to a gasoline generator and it ran just fine. Yes it appears that tar build-up is a problem for wood-gas especially in the case of the FEMA basic design. I wonder if the gas percolated through water would have less tar… how much additional energy would it take to make wood-gas a more long term solution.
After a little perusing it seems that the “DriZzleR Method” is pretty effective at cutting down the tar in the producer gas follow DriZzleR Method at http://thedrizzlergasifier.blogspot.com.au/2014/02/thank-you-pascal-to-give-me-opportunity.html
So how well will it burn human poop? How does the poop need to be prepared? Is it a reasonable use of resources to try and do such? This could have solved the solid sewage problem of living off the grid.
I’ve heard rumors (http://news.mongabay.com/bioenergy/2007/05/researchers-to-develop-biomass-powered.html) of a thermoacoustic all-in-one heater/cooler being developed. What is a reasonable amount of return for such a unit and how big would it be? Energy input to temp change ratio? Would self resonating cylinders be beneficial or hindering to establishing a standing wave? How would it integrate and what could it integrate into?
Garbage: Can plastic be remolded and re-purposed with reasonable effort? What about other trash like cardboard or metals?
Is it possible to use ground temperature in a mobile house situation to assist with heating/cooling? Would the naturally cool ground be an effective component for a sterling engine?
This is assuming that the tiny house is a trailer, how hard would it be to make it self propelled and what kind of spacial real-estate would that require?
Furniture and interior wise, how tight can utility be packed? Multipurposed furniture/rooms. Plumbing, ease of access, spacial arrangement.
Water treatment and collection.
