If you’ve read The Human-Powered Home or followed pedal-power technology a while, you probably know about Maya Pedal. This Guatemalan organization is a model for collaborative, innovative human power engineering. Now Maya Pedal has updated its Web site to include easier navigation, more photos, and best of all, detailed plans and drawings of its most popular pedal-powered machines (bicimaquinas). Through the new site you can also donate or apply to visit and help out.
