                  First delivery of LNG by LNG fuelled vehicle

29th October 2007


Prometheus Energy Company, an alternative and renewable energy company,
announces another "first" using a liquid natural gas ("LNG")-powered vehicle to
transport 10,000 gallons of LNG to a customer.


Prometheus's new LNG-fuelled Kenworth tractor has started shipping LNG from the
Frank R. Bowerman Landfill LNG facility to be used as an alternative fuel for
public transport vehicles in the Orange County Transit Authority ("OCTA") fleet.
In total, the fleet of 232 LNG transit buses consumes over 15,000 gallons of LNG
a day. Prometheus delivered the load of LNG to OCTA on behalf of Applied LNG
Technologies ("ALT").


The LNG tractor provides comparable levels of power, torque and fuel efficiency
to similar model diesel trucks, while also reducing green house gas emissions by
roughly 18-20% or approximately 30 tons of carbon dioxide each year.


Kirt Montague, CEO of Prometheus commented: "We are thrilled to be leading by
example and using clean energy vehicles to deliver LNG to users in the Southern
California market. There is a substantial demand for commercially viable,
alternative-fuelled transportation and delivery vehicles and we are excited to
have the first dedicated LNG-fuelled tractor to be delivering a load of LNG."
