Is there anyone out there interested in the possibilities of tidal, oceanic and non-barrage hydrokinetic power development ??? Technological improvements have extended the range of possible applications to produce reliable and economical electricity with very minimal environmental impact....
What do you know about tidal, oceanic and non-barrage hydrokinetic power development? Are they already in-used or available for the market. What kind of applications they are using or do you the name of applications?
I googled that tidal, oceanic and non-barrage hydrokinetic power development, and got some understanding how that works and it seems more predictable than wind and solar energies.
One of the central problems of hydrokinetic power development is turbine efficiency. Significant amounts of angular momentum can be lost through slippage, resulting in loss of mechanical efficiency. This is why the orginal Bay of Fundy project did not meet expectations. Fortunately, significant technological progress has been made over the last 30 years. There are dozens of small companies making and marketing various designs. One of the major obsticles is the permitting process, but this could be streamlined in theory when various governments, politicians and bureuacrats finally come up with coherent energy policies.
Getting clean, reliable and economical energy with minimal environmental impact is an essential element of sustainable global economic development. In-line hydrokinetic systems are streamlined and fairly straightforward to install.
You might want to try uekus.com as one example of applicable technology and download the global spec toolbar as a good engineering search engine. Also, the US Department of Energy's web site has a list of manufacturers and technology summaries.
Warmest regards,

Wave power and OTEC application are also interesting but seeminingly moree expensive. There is still room for innovation and creativity....

Tidal and riverine energy sources are more predicable and reliable than wind and solar sources but the period of peak production does not always correspond to the period of peak demand, so it is necessary to develop effective storage/conversion systems.
The density of water is about 831 Xs the density of air, so there is proportionately more kinetic energy available...
Water and air densities are easilly referenced in various fluid dynamics, engineering and chemistry text (or on-line). The State of Delaware recently approved a major offshore wind farm (Bluewater) in an effort to develop "green" energy. [ I prefer the term sustainable as "green" is rapidly becoming an advertising cliche'. ] However, the power cost / KWH is increased by the length of the underwater transmission line (7-11 miles). In contrast, hydrokinetic turbines placed in rivers and inlets would require a much shorter cable length and could generate electricity at 60-45% less cost.

Thanks, Wolf, your explanation is impressive, but I can't see the whole big picture without the pictures or images.
Where do you get all these informations? Are you working on these "green energy", renewable energy projects, or just your hobby or a kind of an environmental crusade or something ....
