The power generated by new invented (patent pending) showed at last video JET turbine with 2P shaped blades equal 14x100=1400 vs. power output of the conventional HAWT equal 3x23=69 with same diameter in the same wind conditions. (1400/70=20) The not optimized 2P JET propeller can increase the output by a factor of 20 in comparison with a conventional horizontal axis prop turbine.
New invented JET turbines are much more efficient because operate by both JET and LIFT mode of rotation.
In addition:
1.JET blades reduced tip losses significantly
2.Redirected flow properly
3.Converted centrifugal forces to an additional rotation torque
4.Operate in actuator cylinder (instead in actuator disk). See 2p JET blade rotor operates in inclined virtual cylinder at point 3 of above list of videos.
5.Reduced significantly wake flow speed at low incoming flow speed - it is like a diffuser augmented turbine
6. The noise emissions (sound level) of jet turbine is very low
7. etc......

The JET turbines operate very efficiently as both wind and under water devices.
 

Power Barge for free water flow operation 

New invented JET hydrokinetic technology is designed for use in river, canal and ocean currents with the axial flow fixed blades turbines fitted on horizontal or inclined axis. The core of  our radical new technology is the JET/FRAME design of the turbine blades. Thanks to the additional JET mode of blade rotations new designed turbines can increase the turbine efficiency many times (see  point 5 of above list of videos). The turbines are  mounted on a catamaran type hull or barge and full or partially submerged into the water flowing beneath the barge.

In an open-river setting, hydrokinetic power projects will have a capacity factor (CF) of better than 98% because power will be generated by using a constant water current to the effect that it would be considered a “base load” plant.

The rotational speed of the turbine is very low, and can be stopped from spinning in a matter of seconds through automated fault sensing equipment and the turbine can be lifted out of the water and placed in service mode in under 2 minutes.

The barge on which the turbines are mounted (and the turbines themselves) is able to cope with fluctuations in water levels, substantial velocity increases, and direct impacts from large and fast-moving debris, (the turbine is self-cleaning for small debris and floating plant material) and the only flow parameter that would decrease power output would be a decrease in the flow rate of the water underneath the barge. During extraordinary adverse conditions or flood events, the barge could be removed from the river if necessary.

The first barge is projected to generate 1 MW and produce 8,760 MWh electricity annually at a maximum rating through a synchronous AC induction generator.

Since the power is proportional to the cube of velocity and density of the water, a slower flow rate of (say) 1 meter per second will yield less energy than a flow rate of (say) 3 meters per second, and depending on location and other factors such as depth, our turbine blade size would be engineered for optimal performance given specific site conditions. For instance, the turbine blade could be long and broad for slow moving deep currents, or shorter and thinner for fast moving shallow currents.

The power barge is designed to last for at least 20 years lifespan, and because of very few moving parts, will have very low maintenance costs and downtime.

Barge Location

The barge will theoretically operate much more efficiently in the middle of a straight section of a river, or closer to a bank in a winding river where the water flow speed is higher, and in either case, the location needs to allow river traffic to pass unimpeded and at a safe distance.

Tying into the electric power grid should ideally be at a location close to distribution lines, or alternatively, close to an agriculture, industrial or commercial end user in order to avoid the major expense of lengthy overhead power lines.

Aquatic Life and Environment
Some wildlife advocates may be concerned that hydrokinetic turbines may harm fish and other types of wildlife. This is generally a valid concern where traditional hydro turbines work at several hundred rpm which could cut and kill fish.

Our turbine spins, or the blades move, at the same speed or more as the water flows, and in the same direction of the water flow.

We compared our turbine with published reports by the U.S. Army Corps of Engineers’ for fish mortality equations in order to look at potential mortality to fish and predict less than 1% mortality. We believe that there will be no material adverse impact to marine life, and, and we expect zero impact on water quality as pertains to temperature, dissolved oxygen, or turbidity.

We will offer licenses to selected established hydro electric companies and utilities. We envisage that our licensing parameters will entail full barge design on a client provided data on a site specific basis. The client can then build the barge locally according to our design plans and drawings.

Bold Moves
We believe that our technology makes it unnecessary to build dams with the associated environmental and socio economic impacts.

Vessels and barges of the catamaran hull type today exceed 1,400 tons load capacities, meaning that our turbine could be engineered and built to exceed a hundred tons, delivering hundreds of Mega Watts. It can be deployed on rivers like the Rein, Danube, Mississippi, Congo, Nile, and Amazon to name a few, where several Power Barges could be strung out, or in ocean currents.
