Top 100

Raser is a leader in rapidly developing cost-effective geothermal resources. They are able to harness lower-heat input (200 - 300 degrees F) compared to usual flash-to-steam geothermal processes. In Nov. 2008 they completed their first plant, with power purchase agreement for 7.8 cents per kilowatt-hour, which is nearly twice the cost of the cheapest wind farms. However, unlike wind or solar, geothermal is capable of base-load power production, providing a constant output, 24/7/365.

Instead of using electricity to turn a heat pump to cool a liquid, Raser runs a warmed liquid through a heat pump to generate electricity.

With their rapid, low-cost deployment capability, they could maximize the U.S. geothermal capacity within ten years, if assisted by other companies, to harness the 100 Gigawatts available. By themselves, their business plan sets forth an ambitious roll-out schedule to achieve 1,000 Megawatts by the end of ten years.

Raser is also a leader in developing motors for the electric vehicle industry, which augments the geothermal technology that produces base-load power at a constant output 24/7. The plug-in electric vehicles can utilize the electricity produced through the night.

How it Works

"Their approach is ingenious. Part of their success comes from the principle of mass producing well-established, off-the-shelf (from United Technologies Corp.), modular components.

They also have an edge because of their concept of taking the air conditioning industry technology and essentially running it in reverse. Instead of using electricity to turn a heat pump to cool a liquid, they run a warm liquid through a heat pump to generate electricity.

The secondary liquid that is heated through a heat exchanger from the geothermal-heated water has a boiling temperature of around 60 degrees Fahrenheit. Converting that proprietary fluid to vapor is what turns the generator (heat pump). In this "reverse" direction from the air conditioner, turbines replace the impeller of the heat pump.

This enables Raser to use much lower temperatures than what traditional geothermal plants have required in which water is flashed to steam and run through a turbine. At normal atmospheric pressure, water boils at 212ºF, but under pressure -- typical of a geothermal system -- the temperature can go much higher before flashing to steam. Typical plants require the temperature to be at least 360ºF to be feasible.

Raser's generators are optimized to run on between 200º to 300ºF, which previously was essentially a useless level of heat." (by Sterling Allan

The increased output can be achieved at less than 10% increase in cost. A potential 4 to 1 leverage in profit for alternator manufacturers and their customers.


  • Improves output up to 56% without changing size
  • Increases performance in same size motor or reduce alternator size with same output
  • Provides more power for additional accessories for today's vehicles
  • Delivers the needed increased power to replace belt-driven mechanical and hydraulic devices with electric motor-driven subsystems in order to improve fuel efficiency

  • This proprietary technology allows 20-35% additional power generation through heat transfer. This means more power generated from lower temperature water, allowing more output from an existing site and many more lower temperature sites to become developed.
  • By packaging new technology with up to 35% improvements in power generation and by leveraging and monetizing renewable energy tax credits, Raser is uniquely positioned to execute a timely and potentially very profitable green power strategy.

Independent Testing



Company: Raser Technologies, Inc.

Formed in 2003, Raser is a publicly traded technology licensing company focused on improving the efficiency of rotating electromagnetic and heat transfer applications within the Transportation, Industrial and Power Generation markets. Raser's Symetron™ motor technology is designed to take electric motor technology closer to its theoretical limit. Application of Symetron™ generally requires simple changes to existing products, but yields significant increases in power, performance and efficiency without the use of exotic materials. The company is also expanding its interest in power generation to include the development of geothermal electricity generating plants, deriving revenues from both the sale of the electricity as well as through monetizing the tax credits and attributes that such plants possess.

This strategy combines clean renewable power generation with more efficient use of power in electric motors for hybrid vehicles and industrial applications. This strategy is born from a natural synergy of Raser’s three business segments combining power generation, automotive, and industrial market segments.

The company's headquarters are in Provo, Utah. In the company's motor lab, engineers conduct advanced motor research including the design, assembly and testing of its own new motor designs, and test demonstration installations and enhancements on behalf of its customers.
