Harvey Lacey’s Ubuntu-Blox block building machine was featured in seventh place in yesterday’s blog post on Top 10 Cottage Industry Products. Today’s blog post shows how his block making process has shifted to using extremely low cost materials – vetiver roots, the waste material from making vetiver oil. The end result is similar to straw bales except the bales are smaller, lighter, more insect resistant and they’re made on site with waste materials. The mini bales are less expensive than ordinary straw bales, take up less space and can be made without an expensive baling machine. His open source plans make it easy for anyone to build his machine quite easily.

And a rocket mass heater emits less than a tenth of the greenhouse gasses. Many rocket mass heaters will heat a home with a tenth of the wood of what a conventional wood stove will use.

They look like leaning adobe vaults by the famous Egyptian architect Hassan Fathy, author of Architecture for the Poor. This method uses thinner, medium sized adobe blocks mortared together with mud. The adobes are set into sloping arches that lean against an end wall..
Golden Bamboo Ceilings

I posted a photo a while back about the new roofing tile on our earthbag roundhouse. The exterior looks great, and the roofing tile won’t take any maintenance for 20-30 years. But like I said in that blog post the ceiling is unfinished. The thatch roof that was on it before made a gorgeous ceiling, but the upkeep was too much since thatch here only lasts about three years. It occurred to me that bamboo would look really good on the ceiling. One option is golden or yellow bamboo as shown in these images.
