Seawater energy – the new generation ocean power?

hydro, electricity, ocean power, hydro power, turbines, Malaysia

this small hydro energy system from Malaysia is asking your reaction,

This seawater energy system for hydro energy is different from the earlier sisters.

This one is able to capitalize on the maximum use of the ‘Water Head Pressure Methodology’.


This Ocean power concept is developed by mr. Jalaludin Hashim from Malaysia

With this methodology, the traditional use of pen-stalk, and water draining through the rotor system itself, could just be ignored. Even difficulties in adjustment between high force with low flow and low force with high flow, could be ignored.

With a small operating area, we can produce huge electrical power using the next generation Hydro Power.

Step 1 – Water intake

  • water from the sea is routed to the feeder reservoir on land: take care that the flow of water is continuous and steady
  • marine filters should be placed at the beginning of the entry and then followed by a water gate
  • the gate will stop further sea water entering the system. this could be done when water has occuied all venues within the system. this is due to the water reuse system in place


Step 2 – About the feeder reservoir

  • the height of the feeder reservoir may vary if the area is a flood prone area. This is to prevent the whole system from being submerged into water
  • water is taken from below through bladed cups. This will naturally increase the velocity of water passing through them
  • adjustable nozzles are connected to the outputs through flexible reinforced silicone hose
  • when properly adjusted, water could spear through mid air to bombard the turbine blades, Thus, the blades will  turn harmoniously to operate the generator on top of it

Step 3 – The turbine blades 

  • the turbine blades should be light weight and robust
  • forceful water head will bombarding the blades in a straight line
  • the rotor blades have to move freely. every drop of water should be able to leave the blade instantly. this allows maimum transfer of the kinetic energy to the blades

Step 4 – The turbine generator

  • the generator should be light weight, capable of generating high power output and able to withstand harsh environment and rugged in construction
  • it should be able to start operating when head water pressure of 4 bar is fired to its blades to a maximum pressure of 18 bar
  • distance from firing nozzle to the blade should be no more than 5 ft.

Step 5 – The spent reservoir

  • electronic sensors are used to guard the water level in the reservoir. with the help of a water suction pump,. the water is prevented from flooding the system. ratio between water in to water out should be maintained ad 1:4
  • when the water level reaches the high sensor, suction pump is triggered. the water is transferred back to the feeder reservoir
  • when the water level falls below the low level sensor, the pump stops its operation
  • the process will continue automatically, non-stop
