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.

Top 10 Cottage Industry Products
We covered cottage industry appropriate technology in a previous blog post. The aim here is to identify the top 10 products for ease of construction, impact on community and potential profitability. These products obviously go way beyond just creating jobs and making a buck. The products featured here will have a big impact on local communities. Some are saving thousands of lives. Water filters, for example, help prevent disease. Treadal pumps have enabled hundreds of thousands of farmers to greatly increase crop production.
Allan Savory: How to green the world’s deserts and reverse climate change
“Desertification is a fancy word for land that is turning to desert,” begins Allan Savory in this quietly powerful talk. And terrifyingly, it’s happening to about two-thirds of the world’s grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes — and his work so far shows — that a surprising factor can protect grasslands and even reclaim degraded land that was once desert.”
