NeSSI systems: the approach to a Best Practice The score card to date

NeSSI systems: the approach to a Best Practice NeSSI Generation I: miles in the bank We have a proven operating envelope of gases and liquids (up to diesel) We have seen the cost of components come down to a premium of about 10% We have seen the overall cost of build reduce by about 30% We have demonstrated technician acceptance We have demonstrated self contained systems We have demonstrated SAM jr

NeSSI systems: the approach to a Best Practice The Tipping Point “The moment when an idea goes from being just another word on the street to becoming THE way that everyone thinks.” NeSSI is making good progress on its approach to becoming a Best Practice Decreasing costs Solid field experience with Gen I Commitment to develop Gen II DoE project support of Gen III The Tipping Point for NeSSI could be close at hand The Falkirk Wheel © by courtesy of MG Bennett & Associates, UK
