Hydrogen Powered Turbine Test Proves Successful
DeLand, Florida | September 17 2008

Turbine Truck Engines, Inc. (TTE) (OTCBB: TTEG), a leader in developing environmentally friendly turbine engine technology, is very pleased to report that the company has successfully operated its full scale, fifth generation prototype engine utilizing compressed hydrogen as the fuel source. The company also reported that the test produced zero emissions and required absolutely no modification to switch the Detonation Cycle Gas Turbine Engine from propane to hydrogen. A video of this significant development can be seen on the company’s web site and on YouTube (www.youtube.com).

Michael Rouse, CEO of Turbine Truck Engines, states, “This is another major milestone for TTE. The company is moving forward in a significant way that is catching the eyes of serious investors. Clean air technology of this magnitude is something the world urgently needs.”

“One hundred percent renewable hydrogen gas-from-water technology would literally enable anyone to make their own fuel and power their Turbine Truck Engine using water as the basic ingredient. The test results prove that turbine engine technology, utilizing hydrogen as a fuel source, has the least environmental impact due to zero emissions resulting in a truly green application,” said Mark Johnson, President of HGenerators™ (www.hgenerators.com), the hydrogen gas-from-water electrolysis generator company.
