GCK Technology is a U.S. company that specializes in Grolov Helical turbines designed for use in water settings.

Inexhaustible energy from flowing water created by:

• Rivers
• Small dams built for flood control or recreation
• Tidal currents
• Ocean currents
• Discharge from conventional hydro-power dams
• Discharge from industrial plants

Ecologically benign:

• No raw material consumed in power production
• No waste product to dispose of
• No flooding from dams
• Minimal obstruction of water flow—fish and fauna friendly

A totally non-polluting process

Characteristics

The Gorlov Helical Turbine (GHT) was specifically designed for hydroelectric applications in free flowing low head water courses.
The following benefits make the GHT
especially valuable for generating hydroelectric power:

• Demonstrates superior power efficiency in free currents compared to other known turbines
• Rotates at twice the velocity of the water current flow.
• Self-starting in water current flows as low as two ft/s
• Rotates in the same direction, independent of water flow direction. This is especially advantageous for tidal and wave energy systems.
• No fluctuation in torque
• No cavitation even at high rotating speeds
• Allows construction of environmentally benign hydropower plants without dams
• Modular—can be assembled vertically, horizontally or in any other cross-flow combination using a common shaft and generator for an array of multiple turbines.
• The modular design offers great flexibility, which can simplify and reduce the construction, expansion and maintenance costs of a power generating facility.
• Flexible generating capacity proportionate to the number of modules
• Flexible progressive installation to suit available financing
• Adaptable to local needs—homesteads, villages, islands, cities, countries
Long-term perspectives
• To reduce dependence on central power generation, especially in developing countries
• To provide electrification to remote areas which might never be reached by a power grid
• To reduce dependence of whole countries on exporters of oil, coal, nuclear and other imported fuels
• To open up new collaborative projects between nations to manufacture, install and pay for power supplies, e.g., between North and South Korea
• Can be used onsite to produce hydrogen for fuel cells from oceon or river currents.
