          GTE to receive US Patent for on-wing turbine wash technology


Gas Turbine Efficiency plc ('GTE' or 'the Group'), a leading manufacturer of
advanced systems to clean, monitor and enhance the performance of aviation and
industrial turbines, is pleased to announce that it is to be granted a US Patent
for System and Devices for Collecting and Treating Waste Water from Engine
Washing.

An application for the patent was filed in June 14, 2004 and concerns GTE's
unique, highly atomised water injection technology for 'on-wing' washing of
aircraft engines built by all leading turbine manufacturers. These wash systems
have been deployed by a wide range of aircraft operators through GTE's exclusive
aviation industry partner, Pratt & Whitney, and deliver validated reductions in
carbon emissions, fuel costs and engine downtime.

The patent describes and protects the Group's intellectual property concerning
the GTE Collection and Treatment System, whose key environmental features
include effluent-free, closed loop washing resulting in 100% capture of dirty
water.

Key features described in the application include :

Mobile, Wash Effluent Collection System with:
   • Flexible Positioning and Configuration for Multiple Engine Classes
   • Liquid to Air Separation of Wash/Air Effluent upon Exit from the Engine
     During Wash
   • Funneling of Liquid from Separator and Below Engine Nacelle to a
     Collection and Holding System
   • Waste Water Filtering Treatment for Reuse or Environmental Release


The grant of the patent takes the total number of patents filed or held by GTE
to six.

Steven Zwolinski, Chief Executive Officer of GTE, commented: 'We are delighted
to be granted this patent for our unique on-wing wash system which provides
major environmental and cost benefits to aircraft operators. With a vastly
experienced technology team, GTE will continue to deliver value through
innovation and environmentally-friendly solutions for aviation, power generation
and industrial turbine operators worldwide.'
