Claim:
1. An electricity-generating platform having a buoyancy to at least partially submerge when placed in a stream of water, comprising: a fluid turbine configured to rotate about an axis when placed in a stream of flowing water; an electric generator adapted to generate electricity in response to rotation of the turbine; first and second buoyant lateral side supports, a central longitudinal axis of the turbine extending between the side supports; and a support frame coupling the first and second lateral support to the turbine; wherein the buoyancy of the platform is such that the turbine is at least partially submerged when the platform is placed in the stream of water; the support frame being configured to vertically raise and lower the turbine to adjust a distance between the turbine and the first and second lateral side supports.
