The world faces a future clouded by shortfalls in energy. Forward thinking energy companies stand to reap significant benefits from our technology’s ability to capture constant grid-compatible power from continuously flowing water. River turbines present a viable and sensible alternative to current energy production. Water energy is abundant and renewable –and it’s cleaner and more efficient than coal and natural gas. Rivers flow continuously in one direction, so energy production can be ongoing, delivering a constant and plentiful supply of electricity. While there are several competing turbine technology options in development, most use wind-derived turbine designs that are not water friendly.

The turbine’s technological advantages

The motion control technology used by the DDMotion River turbine offers several benefits over current turbine designs.

  • The speed converter transforms the variable input speed from the river into a constant output speed. There is no need for clutches, belts, pulleys or hydraulics, and power grooming is eliminated, resulting in significant cost savings.
  • The DDMotion turbine does not require a dam to harness potential energy. This reduces construction costs, saves time and resources, and reduces land use. River traffic and fish can proceed freely, and there is no harm to the environment.
  • Most water turbines use electronically controlled power converters that burn out when power input is high, are limited to low power kilowatt ranges and do not allow for scalability. The DDMotion speed converter can accommodate megawatt ranges and is highly reliable.

Key Han

Inspired by his belief that people and machines can solve complex problems and open new frontiers, Key Han, the founder and chief technology officer of DDMotion, spent ten years perfecting his designs and prototypes for mechanically driven, infinitely-variable motion controls. The core element of Mr. Han’s designs is a patented gear assembly that has three variables. The name Transgear™ gear assembly derives from its similarity to the way transistors function in electronics. And like transistors, it has unlimited applications across all industries.  
“Once in a great while, a technology is introduced with the potential to change the way the world works for the better. With its infinitely-variable motion control, DDMotion has created such a technology.” Alfred R. Berkeley III, Former president of NASDAQ Stock Market, Inc.
