The floatable mini-power-plant is constructed very simple. It consist of 2 pontoon tubes, an attached generator and a bucket wheel gear. In order to drive it, one needs only to use the flow energy of any flowing water. The blades of the bucket wheel gear are driven by the natural water movement and the attached generator can generate electricity thereby. That’s all! A damming of the water is therefore not required. It’s suitable for use in large rivers as well as in small streams or canals with lowest water depth.
These mini-bucket-hydroelectric-power-plants have been designed and tested by a developer from Southern Germany in cooperation with Perebo-Schwimmsysteme.
A LIGHTWEIGHT, ECONOMICAL AND FLEXIBLE HYDROELECTRIC POWER PLANT.
The floatable bucket-power-technology is inexpensive, easy to place at the operation site, suitable for continuous operation and is low maintenance. Special advantage: Once installed, it automatically adapts to different water levels as well as flow velocities. Furthermore, the floating-power-generation-unit can be fixed by means of 2-4 piles and thus also secured against theft.
Example: floating hydroelectric power plant L/W= 2,40m / 0,80m
Construction type: catamaran
Output: approx. 5KW (this is equal to the electricity requirements of 1-2 households)
THE GLOBAL CLIMATE CHANGE REQUIRES NEW IDEAS AND INNOVATIONS
Particularly in times of global climate change, the described energy generation from hydropower plays an important role. The reason is that the generation of electricity from hydropower is low-emission and also constantly available. In addition, hydroelectric power plants are one of the most lucrative power generators. In developing countries the described small-scale-hydroelectric-power-plants can, for example, replace obsolete energy generators such as diesel generators. Consequently, a clean, reliable and cost-effective generation of electricity could be offered now.
The beauty is that the HEB works in pretty much any type of river, regardless of depth or flow speed (though that will have an impact on the quantity of power generated).
How it Works
From the HEB website: “The barrel is one-piece moulded plastic with paddle treads and two integral planet gear driven permanent magnet generators installed making this a relatively light assembly for transportation and installation.
The rotating barrel turns the generator case which drives the planet gears which in turn spin the discs which holds the permanent magnets
The movement of the magnets induces electrical current in the coils which are held stationary.”
There’s even a version (second picture) that could harness the ocean’s waves and tides to generate electricity.
Power output for two models, a 1.5 meter one and a 2 meter one (graph above), has been calculated:
Calculation using simple formula for POWER
Horsepower = Torque (foot pounds) x 2 pi x rpm / 33000 which simplifies to:
Horsepower = Torque x rpm / 5252.
Finding TORQUE by calculating the water pressure on the paddle area using:-
Paddle Area x Length x density of water x (Velcity of current2 / 2 x gravitational constant)
And multiplying this by RADIUS
Of course some real-world testing will be required to make sure that it works as planned, and that it is cost-effective compared to other micro-hydro solutions.
