Losing coins are not a problem as they are infinitely divisible. Currently only to 8 decimal places, but that can be increased if needed. One bitcoin or even a fraction of a bitcoin is enough to run the whole world economy.

There has been much debate as to the credibility of Mr. Rossi because he has a criminal background, but apparently he has been telling the truth about perhaps one of the greatest inventions in history of mankind.
ecatfollower writes: Andrea Rossi's cold fusion device was covered on Slashdot before. It uses nickel, hydrogen and a secret catalyst. In contrast to many earlier cold fusion or LENR (low energy nuclear reaction) devices since Fleischmann and Pons in 1989, which worked at very low power levels and showed just marginal excess heat and suffered from difficult reproducability, the e-Cat outputs power at practical levels in the area of hundreds of Watts to kiloWatts, with claimed coefficiencies of performance (COP) of around 6, meaning 6 times as much heat comes out as is put in. Always.
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.
