I would say the major deficiency of NA home building is air infiltration followed by insulation. Thermal Mass is way down the list after the likes of attached garages, ducts in unconditioned spaces, and ventilated crawls and attics.
I agree with carpeting being a bad idea but forced air is one of the greatest things most homes can have.
They're very friendly at Maya Pedal and would probably send you a free copy, even though that specific one is not available on their site.
I would love to find some plans for the roof tile machine. That would have a huge impact on my village in Northern Mexico.
Yeah, If you find anything about home made tiles I'd like to see it too
I spoke with MayaPedal and their bicycle-operated cement tile machine costs $160 here in Guatemala, including the tile mould. CargoExpress would be the company to approach for transport. They don't have CAD plans yet but they're working on them.
I haven't really seen any open source designs for building the vibrating table or tile molds.
