How It Works

Unlike conventional hydropower which requires gravity drop and head pressure for effective operation, Emrgy’s technology optimizes only on the kinetic energy or velocity of the volume of water flowing through a channel. Much like a wind turbine placed underwater, the water flow through Emrgy’s flume causes the twin turbines to rotate and create torque and speed around the shafts. This mechanical power is transmitted through our proprietary magnetic gearbox to achieve high speed rotation for seamless integration with an efficient electric generator. The concrete flume optimizes water flow to the turbines as well as provides structure and ballast for the entire system.

Twin Turbine Design

Allows for maximum power production with minimal environmental impact.

Efficient

  • Proprietary turbine design is capable of capturing 70% of the available energy at a given point along a river or canal
  • The use of a twin-turbine offers higher performance than a single turbine

Flexible Operation

  • Self-starting and bi-directional operation enables unattended power production
  • Turbine modules can be vertically stacked for larger cross-sectional flows

Low-Impact

  • Ultra-low solidity allows for fish-friendly turbine operation
  • Induces minimal change to baseline flow conditions
  • Localized flow engineering minimizes cumulative effects of the turbine array within a given waterway

Magnetic Gearbox

Enables transfer of torque and speed using magnetic fields versus mechanical teeth for increased sustainability and flexible operation.

Efficient

  • No loss of energy due to virtually frictionless operation
  • High 30:1, single-stage gearing
  • Speed ratio is fixed at 30x due to magnetic pole pairs, potential for very high gearing (up to 150:1)

Flexible Operation

  • Operation using magnetic flux allows for high performance across a range of input torques and speeds
  • Protected from overspeed and over-torque failures

Low-Impact

  • No oils or lubricants necessary
  • Decreased acoustic signature for wildlife compatibility

EmrgyFlume™

Provides ballast to overall system without permanent anchoring or infrastructure changes.

Efficient

  • Flow acceleration up to 200% from baseline flow conditions to increase the amount of power available to the turbine

Flexible Operation

  • Minimized turbulence
  • Easily installed and removed

Low-Impact

  • No permanent changes to existing infrastructure
  • Encouraging local economic development through the use of vendors in the region of the customer
  • Made of inert materials
