Harvey Lacey is the inventor of the open source Ubuntu-Blox building technology. We caught up with him in Port-au-Prince, Haiti in November, 2012, when he shared his latest discovery: using agricultural waste from vetiver to build Ubuntu-Blox in rural areas for a fraction of a penny.

Thanks to Harvey Lacey for sharing his wisdom with us, and to Haiti Communitere (www.haiti.communitere.org) for providing a space to nurture both the Ubuntu-Blox project and ChangeStream Media's (www.changestreammedia.org) outreach efforts in Haiti.
