Technology Working Group

The technology working group develops technological innovations related to small wind systems.



The technology working group is composed of a decentralized group of specialists which develop and improve upon technology issues facing the WindEmpowerment membership.
  • Blades : Building the better blade. Techniques with wood, experiences with fiberglass and 3D.
  • Charge controller : Designs for a simple analog DC charge controller. Plus discussions and information on building a digital, more advanced charge controller and a charge controller for grid tied applications.
  • Power converters : Work in progress on a DC to DC charge controller
  • Direct water pumping: Testing and experiences with direct pumping using a small wind turbine and solar. Tests and improvements
  • Towers : Building a free standing 18m lattice tower, which can be raised and lowered. Guy wired tower designs
  • Electrical systems : Cable losses, designing on and off grid sites.
  • Bigger turbines : Designing a 5m turbine.
  • Additional resources : Lightning, generators, batteries.
