The Andrea Rossi LENR experiment surrounding nickel-hydrogen has become the latest buzzword in the scientific and academic community. The race is definitely on for four companies – Leonardo, Defkalion, Brillouin and Nichenergy – to bring LENR technologies to commercial success. The latest e-cat guide stated that LENR needs to provide clear evidentce that it is useful to users when used in their real lives. It is hoped that LENR is not limited to giving flamboyant words to explain its claims but to really see to it that it is valid and true. This is a very important invention and people will only give it a serious attention if it can provide legitimate solution to energy crisis.
