“The unit takes one person two days to construct, one day to install, and costs under $100. The temperature inside the unit easily reaches 160 degrees Fahrenheit on a 50-degree day, and can be blown into the house using a fan that pulls less electricity than a light bulb.”

2 Year Forest Garden Update: Forest Gardens as a Hedge Against Drought
This is my annual video update of our forest garden. I’m calling it ‘Forest Gardens as a Hedge Against Drought’ for reasons I’m about to explain.

It’s so bad that many farmers aren’t even plowing and planting. This is the worst rainy season in 15 years and yet our garden is still very lush. It’s not growing as fast as when it rains because plentiful rain softens the subsoil so roots can grow more readily, but our forest garden is still a lush oasis as you can see in the video.
Modern Tiny House in Alaska

Proof the Outer Layer of the Pyramids Was Made with Cast in Place Cement
This is the evidence I’ve been waiting. For several years now I’ve been hoping to find close-up detailed photographic evidence of Michel Barsoum’s and Joseph Davidovits’s theory that at least part of the Giza pyramids were cast in place using an ancient type of geopolymer. Well, here it is.
Rammed Earth Block Machine Makes Clay Materials Harder than Concrete
Guest post by Alex Wright of Watershed Materials, the company who’s making geopolymer concrete blocks out of waste clay materials. We’ve covered their exciting development in two previous blog posts. This article focuses on their rammed earth block machine.
