Are you saying the JET tokamak reactor with a Q=0.67 is endothermic? It swallows up heat? How much, for how long? I have heard of cold fusion cells that were measurably endothermic for a while, but as far as I know all plasma fusion reactions are exothermic. If the JET reactor absorbs energy, the hot fusion program is in worse shape than I thought. > Second, changing electrode dimensions will not necessarily change >Q. I did not say it necessarily does. It sometimes does, but the change is unimportant. - Jed
