Success for Andrea Rossi's E-Cat cold fusion system, but mysteries remain

Against all the odds, Andrea Rossi's E-Cat cold fusion power plant passed its biggest test yesterday, producing an average of 470 kilowatts for more than five hours. (A technical glitch prevented it from achieving a megawatt as originally planned). The demonstration was monitored closely by engineers from Rossi's mysterious US customer, which was evidently satisfied and paid up.
