LENR is a much better name for a still little-understood phenomenon.
From the NASA archives:
"Low Energy Nuclear Reactions is a source of thermal energy. It is an immature technology that requires further research to determine the best propulsion system integration on a vehicle platform. LENR has the highest specific energy of the alternative energy sources mentioned at about 51,000,000 Wh/kg.3
This is a conservative estimate from the recent LENR reactor test that was conducted in March 2013."
