A Bolognese radio station, Città del Capo Radio Metropolitana, recently interviewed Loris Ferrari and Giuseppe Levi from the University of Bologna about their R&D contract with Andrea Rossi.
According to the article, the study will last for at least a year, financed by Rossi, and it will take at least six months for the results to be published. (Although the research group may release some preliminary results as early as December, 2011.)
Some aspects of the research may be subject to trade secret protections.
