New local power technologies

For readers interested in medium-scale projects to create sustainable power (for instance to supply a village), the South African German Chamber of Commerce recently showcased new technologies of the following types:

  • A solar steam turbine without blades. It has energy storage capacity; a biomass burner can be added for operation in absence of sunlight.
  • The first-ever fish-friendly water power plant, which can operate on virtually any water source, including industrial waste water systems and tidal ranges, above or under ground.
  • A vertical wind turbine that uses no horizontal rotor blades. The new rotor concept increases energy harvest. The turbine is designed for decentralised application and operates well in extreme weather situations.

Although these technologies are not yet available "off-the-shelf", nor have they been trialled in Africa, they are deemed appropriate for Third World implementation.
