Renewable Energy Solutions and Energy Conservation

Energy Conservation -ESME

Whatever the goal of our customers, whether it be power generation, improved process efficiency or reducing their carbon footprint, the ESME unit can improve company targets by conserving energy.


The ESME product is a simple skid module, custom built to take advantage of industries waste heat streams.  The system is based on a simple Brayton cycle, utilizing compressed air.  The air is heated and expands through a proprietary air turbine.


For industries looking to conserve energy and take advantage of their waste heat, the ESME team can help.  The electricity produced depends on the temperature and volume of waste heat streams.  With this information and a simple process diagram, ESME engineering and sales can present a system custom designed for your needs.  There are no fees for the analysis.

NWG Friction Drive Technology

The illustrated wind turbine drive has a rated power of 2.0MW.  NWG has received third party validation of the design from 65kW to 7.5MW.  The diversity of the drive is evidence of its eloquent yet simple design.


The engine features a steel wheel connected directly to the wind turbine main shaft.  The engine features a steel wheel connected directly to the wind turbine main shaft.  The steel wheel drives multiple generators via output shafts.  The output shafts are coated with proprietary polyurethane.  The shafts are directly coupled by friction to the drive wheel.

One purpose of the new drive is to provide wind turbines the ability to absorb sudden wind gusts.  The friction drive will filter torque and only allow the pre-set torque to be transmitted to the generators.  When the torque exceeds the pre-set limit, the output shafts “slip”.  This protection feature is instantaneous but does not take place unless an overload occurs.  The inertia stored in the blades during the wind gust or over speed is ultimately recovered as useful energy once the gust has passed.  Several other features enhance the appeal of the friction drive.


The multiple generators provide great advantage.


The 2.0MW unit has 8 output shafts, 4 on either side of the steel drive wheel.  Each output shaft is controlled independent to the other.  That means at a low wind speed of 3 m/s the first generator engages, operating at its maximum efficiency point until the wind speed increases beyond its rated power and then the second engages, then the third, and then the fourth. This leads to greater operating efficiencies.  If for example one of the generators should fail, the others can maintain operation until the repair can be made, limiting downtime.


The design also features an internal crane.  Each of the output shafts and generators are able to be hoisted down the center of the tower, eliminating the need for an external crane for repairs or replacements.

NWG Friction Drive Technology - Beta Testing

CWIND Friction Drive Wind Turbine

Clinton, Ontario, Canada

In 2007, New World Generation purchased a used gearbox driven wind turbine. The unit was rated at 65kW. The Company then retrofitted the gearbox with the newly designed friction drive. In addition, a new control system was designed and installed. The control system included real time data acquisition, which provided evidence of performance. The tower and blades were refurbished.


After one year of operation the data from the original gearbox drive and the data from the new friction drive were compared. The friction drive operated 25% more efficient.


In 2009, New World Generation discovered a company developing a proprietary polyurethane material. The material was tested and out-performed the test equipment. The coated output shafts performed as expected.
