Eng. Andrea A. Rossi and Professor Sergio Focardi of the University of Bologna (one of the oldest universities in the world ), have announced to the world that they have a cold fusion device capable of producing more than 10 kilowatts of heat power, while only consuming a fraction of that. On January 14, 2011, they gave the Worlds' first public demonstration of a nickel-hydrogen fusion reactor capable of producing a few kilowatts of thermal energy. At its peak, it is capable of generating 15,000 watts with just 400 watts input required. In a following test the same output was achieved but with only 80 watts of continual input.
I'll wait for the first reactor being built before getting excited.
