OblinArk Delivers Technology

Localized energy production, energy where it is needed.
A comparative low cost solution to run in river hydro kinetic power generation

OblinArk Built @ TCFabs Plesley Vale Mansfiled

The Ark is based on a boat design with an integral series of water wheels. Its size is fully scale able and modular, dependent on the local environment. There is no reason why versions several times larger than the first production models cannot be built and implemented.
