Gizmag, an on-line magazine with articles on emerging technologies, has an article on an interesting new wind turbine. The design is for an ocean-based system but could also probably work in a big lake with semi-constant wind such as Lake Nicaragua.
In addition to savings on the cost of support structures typically needed for land-based systems, it also includes some energy storage. That addresses one of the problems with both wind and solar energy sources.
