UC Davis designed a CoolBot cool room (excellent project for homesteaders!) using rice hull concrete for insulation and a CoolBot controller to keep farm produce fresher. The cool room paid for itself the first year and even helped make a good profit for local farmers. The rice hull concrete was poured into forms to make insulating wall boards. This blog post will briefly summarize the outcome of their project. The full report is available online for free and can be found by searching for the title of the report: Cool room insulation – UC Davis D-Lab

I bought a fantastic piece of land in Chiang Dao, northern Thailand, and spent several years in the UK saving like mad.
Rice Hull/Clay Blocks and Earthbags
We’re experimenting with rice hulls and clay to make lightweight building blocks. We’re using 25% rice hulls on our first test block. This is our first test block with a rice hull/clay mixture. This is not the most efficient way to mix it, of course, but we’re just doing small samples. Normally you’d use a … Read more
Earthbag Walls in One Day?
How would you build earthbag walls up to 12 feet above ground on pier footings? A reader asked me this recently. Hmm. Moving tons of earth up that high would be difficult, and that got me thinking of alternatives. One solution I came up with uses an insulation blowing machine and hand-held bag sewing machine … Read more
