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.
