Regarding the 'shell' of various LENR reactors, I wonder if someone could recap or comment on what the history has been and what some of the considerations and rational were behind them. Most reactors have been built around steel if I'm not mistaken, and some of glass. The new Rossi model is of alumina and I wonder what led him to that? Also, someone a good while back, Jones I think, mentioned about maybe silicon carbide having some beneficial features (electrical or electromagnetic?). People have mused about what kinds of physical or geometric, micro or macro, configurations might help, and all this seems to me to be of value. I also had another wild (dangerous!) thought----- heating by microwave? cheers, ken
