The technology is apparently up to 15% efficient. This will be quite effective for a very small configuration of e-cat. If one were to take a small format e-cat which produces 1 kw, and match it with this technology one would end up with a relatively useful 150 watts. The smaller format e-cat core would potentially be really quite small. The amount of thermal and radiation shielding required is certainly still a question. A complete system would have to contain a battery sufficient to provide starting heat. The whole rig might be able to fit into a lunch box — maybe.
