| February 2005: Costa Rica Workshop (SEI and Hugh Piggott) |
 |
| Hugh Piggott discusses some basic electro-magnetic theory. |
 |
| The metal frame for the 12 ft machine is square instead of the shield shape generally used for the 8 ft machine. |
 |
| The metal body is tacked together. |
 |
| Norman Gutierrez does some rough cutting of a blade to get it down to approximate shape. |
 |
| Ian Woofenden of Solar Energy International (SEI), and Vilma and Herman of the Durika community. |
 |
| Jim Hogue, a new blueEnergy volunteer, shapes a blade. |
 |
| Hugh holds a 6 ft blade that is in progress. |
 |
| The wood shop. |
 |
| Jeff Homan and Hugh try out a new kind of saw. |
 |
| A Durikan workshop participant. |
 |
| The blade rotor is assembled in the wood shop. |
 |
| Brian Vick positions the turbine body for final welding. |
 |
| Hugh goes over some theory on power and furling mechanisms. |
 |
| Brian Faley, Chris Chavez, and Ryan Woofenden work to remove a magnet rotor from its mold. |
 |
| The square stator is cleaned up for assembly. |
 |
| The nearly finished blade rotor is balanced. |
 |
| A perfect example of the use of local materials. A spare engine block was cut in half and used as the heat sink for the diodes rectifying the alternator's AC current into DC current. To the left is the dump load, constructed out of spare hot shower filaments. |
 |
| The electrical shop. |
 |
| Another view of the power board. Bottom left is the charge controller and bottom right is a brake switch to shut down the turbine. |
 |
| The alternator is assembled. |
 |
| The tower is carried to the ridge where the turbine will be installed. |
 |
| All the workshop participants and some community members gather to assemble the turbine and raise the tower. |
 |
| Hugh and Ian go over some final plans before tower erection. |
 |
| With the power board set in its temporary position, a crew prepares to raise the tower. |
 |
| The tower is first raised without the turbine to adjust the guy wires and make sure everything and everyone is ready. |
 |
| The turbine is mounted onto the tower and the tail vane is attached. |
 |
| The assembled and mounted alternator and tail vane. |
 |
| The turbine is raised. |
 |
| Norman looks on as a crew attaches the ginpole to an anchor. |
 |
| Community members inspect the installation. |
 |
| The turbine and its creator. |
 |
| The entire crew. |
