A while back, I responded to a claim from Lawrenceville Plasma Physics that they were close to a commercial fusion reactor. I was annoyed that such claims were being made and even more concerned that such claims were not receiving a strong criticism from the scientific community. I read the paper published in the journal – Physics of Plasma by Lerner and his colleagues. The journal is a reputable peered reviewed publication. It was clear to me that the paper was not significant. Dense plasma focus devices are well understood and have been modeled in detail. The results quoted by Lerner did not show that the focus device which he has developed was significantly better than other devices and there was no evidence that a commercial fusion device was any closer.
