"table top" pico hydro system for small device charging and lighting.

The Turgo turbine is an impulse type turbine; water does not change pressure as it moves through the turbine blades. The water's potential energy is converted to kinetic energy with a nozzle. The high speed water jet is then directed on the turbine blades which deflect and reverse the flow. The resulting impulse spins the turbine runner, imparting energy to the turbine shaft. Water exits with very little energy. Turgo runners may have an efficiency of over 90%.

A Turgo runner looks like a Pelton runner split in half. For the same power, the Turgo runner is one half the diameter of the Pelton runner, and so twice the specific speed. The Turgo can handle a greater water flow than the Pelton because exiting water doesn't interfere with adjacent buckets.

This turbine is made from scrap that uses the water fall off of an existing dam. It is a more traditional water wheel type turbine. It has paddles made from PVC pipe halves and appears to be making a decent amount of power.

A tour of the Wilson home which utilizes solar water heating, solar pv, wind power, thermal mass, green roof, etc. This is a great example of natural living

This design is a departure from the traditional turbine design for wind power. This new design uses the wind to vibrate a mylar strip to produce electricity. This new design is very cheap, and is capable of powering lights or a radio with a very small unit.
