FlexEnergy

• The Flex-Microturbine (Flex) is the only
  ultra-low Btu power plant that can use fuel with
  a concentration level as low as 15Btu/scf -
  pipeline gas is 1,000 Btu/scf
• Low Btu gas is a costly problem for industry -
  the Flex turns this into a revenue opportunity
• Reduces NOx and carbon footprint - NOx below .1
  ppm or one tenth of any other system
• Low Btu fuel is a multi-billion dollar untapped
  market opportunity
