Consultants and Designers in Micro Hydro Engineering

Poncelet Wheel

Making Micro-Hydro Energy available using this novel 1820s Technology with a modern approach. Suitable for domestic and commercial applications up to 100kW.

Archimedes Screw

Ancient Greek technology applied using modern materials and processes for cost and efficiency savings, generating micro-hydro electricity suitable for up to 15kW.

WaterWheel Design

Other types of Water Wheel can be designed to suit specific site locations; for example using Overshot, Breastshot or Zuppinger Wheels. We also design hybrid wheels.

Ocean Hydro Electric Generator (OHEG)

The OHEG is a revolutionary hybrid concept using the tide to produce energy. The power is produced by using both the kinetic energy in tidal flow and the potential energy created by tidal height changes, utilising offshore storage lagoons to retain the mass of water. The structure is fixed to the sea bed and the water velocity is increased by incorporating a venturi arrangement.

See below an artist impression of a 10MW system.

Ocean Energy Rig (OER)

The OER is another hybrid concept harnessing tidal stream with increased velocity from a venturi system, wave and wind power. This system is floating and anchored to the sea bed, being brought back to dock for servicing or repair.

Below is an artist impression of a prototype.
