Given the fuel consumption rates reported from public demonstrations, global annual nickel production would suffice to fuel global annual energy consumption, without affluent, carbon emission, or radioactive waste (with 100 years of present reserves). It seems media shyness from the 1989 cold fusion debacle has managed to keep coverage below radar levels outside of Italy. Will the operation of a 1MW plant in Xanthi, Greece, scheduled for October be enough to overcome the giggle factor, and unleash a truly disruptive energy technology?
