Preparata was one of the greatest minds from what is becoming the hotbed of new fizzix thinking. He was in a long line of Italian physicists who took the unconventional to the max and did not back down from peer ridicule. It did not begin and end with Fermi, but he must have been a prime inspiration.
Xue is another brilliant an unconventional Italian physicists (transplanted) whose novel ideas could contribute to alternative energy in the future - more so towards ZPE. However, many of us are convinced that ZPE plays at least an auxiliary role (if not major) in whatever is behind NiH excess heat. I need to check to see if Xue has written anything on the Rossi madness. Prof. SheSheng Xue is in Rome; and could have been part of the OPERA faster than light team (not sure) - author of 4 papers on "vacuum-energy releasing" technology. Xue is co-author of papers with Preparata & del Guidice going back to 1994: http://arxiv.org/find/grp_physics/1/au:+Xue_She_Sheng/0/1/0/all/0/1 Xue wrote other papers on important frontier topics, such as: http://arxiv.org/pdf/0807.0909 Electron-Positron Pair Production in Space- or Time-Dependent Electric Fields http://arxiv.org/pdf/0804.4619 Phase structure of Einstein-Cartan theory Co-authored with Hagen Kleinert, a top expert (along with Prof.Fred Hehl) on torsion in spacetime, and unified-field (EM+gravity) theory.
