Tinkerers, utopians, urban farmers and others will have a smile on their face when they visit Open Source Ecology, they will see 50 machines that compose the Global Village Construction Set, not a Lego set but machines that do jobs from producing Compressed Earth Blocks to Well Digging Rig.

The whole Open Source Ecology effort is presented as "Open Source – Low-Cost – Modular – User-Serviceable – DIY – Closed-Loop Manufacturing – High Performance – Heirloom Design – Flexible Fabrication."
