On a trip to Taos, NM visiting Earthship Biotechture. We’re staying in the Phoenix and YEAH I had to bring a boombox! This Yorx K6061 is small enough to pack in a medium sized suitcase. Playing 8-tracks. You have to open every new 8 track and fix the pads and the splice or there could be trouble. Once fixed, you should get another 30 years!

Earthships capture rainwater and filter it. Use that water four times before it leaves the building (1st for drinking and washing, then watering plants inside, then filtered for flushing toilets, then outside into a septic that feeds landscape plants. Any extra water not used for the toilet goes straight to the landscape plants.
Earthships stay 70F temps inside, year round without heating and A/C. They use solar to heat water and the plants clean the air inside. They are hurricane and tornado proof and resist fire.
We’re building one right now, so we visit for ideas!
In fact, I like this mini so much I already have another of the same model on it's way to me.
