Seabell International > "Stream" Small Hydro Turbine System


STREAM creates compressed water flow (current) energy, similar to water drop (head) energy. the biggest benefit of the system is no need of Dam construction.

Simple structure based on hydraulics

Focusing on "How to accelerate current velocity" world's first invention of Dual axis turbine, Opposite rotation accelerating gear system and system from reducing friction loss.

Non-head power generation - do not need dams, resevoirs or waterfall
Because the STREAM converts energy from water current, it is unnecessary to create an artificial head.

Efficiently utilizes the greatest water flow speed at water surface
The STREAM is a micro-hydropower turbine that floats above water, enabling highly efficient electricity generation by capturing the largest energy that exists at the water surface of rivers and water ducts.

Stable electricity from infinite water source
Hydropower from predictable water flow can generate more stable electricity compared to those of wind or solar due to higher utilization rate.

24H/365 day of Reliable energy source


Different from Solar power, Wind power or Conventional type of Head hydro power, STREAM provides reliable new energy power generation by Water current, stable power for consistently 24 hour.

Current energy has a good efficiency on per unit (certain area / volume) comparing with other renewable energy sources. For example, the energy of 1m current/sec is equivalent to approx 10m/sec of wind velocity, and it has a large potential to become one of major renewable energy sources on the earth, near in future.

Power generation amount of STREAM

amount of power generation of our system depends on the amount of water flow volume, speed, and the shape of the main body (inflow area/blade diameter). furthermore, the amount is affected by the installed environment, whether in duct or river, and the seasonal fluctuation in flow volume. rated flow speed (normal flow speed of ducts) and flow volume (normal inflow volume) is given only as a yardstick. for example, when the flow speed is low, the in-take flow volume is high, necessitating the main body to be relatively larger. on the other hand, when the flow speed is fast, even though the volume is relatively low, it can still accomplish the projected rate of power generation. for details on conditions, please contact us.
