Green Machine & Earthen Construction

In my opinion, this is the most sensible material one can choose for construction. There are examples world wide, and not just single family homes. I am familiar with a manufacturer of machines very similar to this in San Antonio and have been supporting compressed earth construction for years. Incidentally, the choice of soil to use in block making is important, and with some care and basic inexpensive testing, many soil mixes can be used without depending on portland cement. Soil too sandy, add clay and vice versa. Provide the right proportion of sand, silt, and clay. Leave out organic material (top soil). No need to worry about blocks dissolving in the rain even in hot, humid, or rainy climates. Design sensibly with proper overhangs and most importantly with lime plaster. 100% fire proof, mold proof, bullet proof, humidity-moderating, and phase change material. Conventional construction just can't stack up. Oh, and who would ever take demolished dirt walls to the landfill?

Interesting technologies but

Interesting technologies but the ones on recycled wood are old ideas.

Otherwise there a wide range of other ideas which need to be tracked like Vertical farming.
