Although we don’t know all the secrets of the E-Cat, from what we have been shown it is quite a simple device. You have a reaction chamber in which nickel, hydrogen and the unknown catalyst are combined, which is attached to a plumbing system through which water is pumped. There are also some electronics involved, including the mysterious radio frequency generator, but nothing too high tech that would put off a determined experimenter who is trying to replicate this device at home.
Andrea Rossi is aware of the E-Cat building going on out there, and has just issued a statement about it.
WARNING TO THE READERS:
I HAVE RECEIVED IN MY EMAIL MANY MESSAGES OF PEOPLE ASKING INSTRUCTIONS TO MAKE IN THEIR “BACKYARD” A PROTOTYPE TO REPLICATE THE EFFECT. I WANT TO REPEAT AGAIN WHAT I ALREADY WROTE IN THIS BLOG: PLEASE BE VERY CAREFUL: HYDROGEN IS EXPLOSIVE AND NICKEL POWDER IS TOXIC. TO TRY THE EXPERIMENT IS VERY DANGEROUS AND IS POSSIBLE ONLY FOR PROFESSIONALS, IN PROPER LABORATORYES AND WITH PROPER SAFETY DEVICES AND CLOTHES, GOGGLES, GLOVES, ETC ETC.
IN PARTICULAR, IT IS MANDATORY THAT NO MINORS ARE EXPOSED TO THESE RISKS (A LADY TOLD ME SHE WAS MAKING AN EXPERIMENT IN HER KITCHEN WITH HER CHILDREN…..)
AGAIN: PLEASE DO NOT USE HYDROGEN AND NICKEL POWDER IF YOU ARE NOT A PROFESSIONAL SUPPLIED WITH ALL THE NECESSARY EXPERIENCE AND INSTRUMENTATION, SAFETY DEVICES, INDIVIDUAL PROTECTION CLOTHES.
Rossi is not so naive as not to expect that people will not try and replicate his technology, and he is not attempting to stop replication attempts, but he is clearly worried about accidents that could happen if safety precautions are not followed.
