The $50 Water Turbine -DIY, Portable, Powerful, and Open Source

My name is Daniel Connell. I prototype and develop basic technologies which anyone can make using recycled materials and simple tools.
The aim is for everyone everywhere to be able to build and maintain their own infrastructure; producing their own energy, food, clean water, communications, and anything else they need.
All designs are open source and license free for any purpose, and full construction tutorials and how-tos are available on the opensourcelowtech.org website.
