In November, December and March, Rossi allowed a team of researchers and professors from different universities to do independent measurements on his device. The team included professor Giuseppe Levi of the university of Bologna, and Hanno Essén of the Royal Institute of Technology in Sweden. The report of this independent test has now been published on arXiv (http://arxiv.org/pdf/1305.3913v1.pdf). The team concludes: "Computed volumetric and gravimetric energy densities were found to be far above those of any known chemical source. Even by the most conservative assumptions as to the errors in the measurements, the result is still one order of magnitude greater than conventional energy sources." In other words, they say: it works as advertised.
