Shortly after Richter's conference, the matter was discussed in the Bulletin of the Atomic Scientists, where it was noted that Richter's announcement had revealed no details of the system of operation. They also noted that Richter claimed three key advances during experimentation, but failed to mention any of them during the conference. Finally, although the method for measuring temperature was announced, the temperature itself was not. The United States Atomic Energy Commission's (AEC) comment on the announcement was simply that "the Argentine Government announced more than a year ago that it was planning to engage in nuclear research."

American physicists were universally dismissive of the announcement. Among the more famous responses was that of George Gamow, who said "It seemed to be 95% pure propaganda, 4¾% thermonuclear reactions on a very small scale, and the remaining ¼% probably something better." Ernest Lawrence was not so dismissive, noting that, "There is a tendency to laugh it off as being a lot of hot air or something. Well it may be, but we don't know all, and we should make every effort to find out." Edward Teller put it succinctly, "Reading one line one has to think he's a genius. Reading the next line, one realizes he's crazy."

British scientists, at that time working secretly on the z-pinch fusion concept, did not rule out the possibility of small-scale reactions. George Thomson, at that time leading the United Kingdom Atomic Energy Authority (AEA), suggested it was simply exaggerated. This opinion was mirrored by Mark Oliphant in Australia, and Werner Heisenberg and Otto Hahn in Germany. Perhaps the most biting criticism came from Manfred von Ardenne, a German physicist now working in the Soviet Union. He advised that people should ignore Richter's claims, noting that he had worked with Richter during the war and said he confused fantasy with reality.

In May, the United Nations World magazine carried a short article by Hans Thirring, the director of the Institute for Theoretical Physics in Vienna and a well known author on nuclear matters. He stated that "the chances are 99 to 1 that the explosion in Argentina occurred only in the imagination of a crank or a fraud." When Thirring heard the announcement, he had gone searching for anyone that knew Richter from before he arrived in Argentina. He found that Richter had studied under Heinrich Rausch von Traubenberg in the 1930s, who described him as a peculiar eccentric, but von Traubenberg had died in 1944 so there was no way to follow up on the story. Richter's dissertation was never published, and the university in Prague burned during the war. Richter was invited to prepare a rebuttal, which appeared in the July issue. He simply dismissed Thirring as "a typical textbook professor with a strong scientific inferiority complex, probably supported by political hatred."

Although essentially dismissed by the scientific community, the Richter announcement nevertheless had a major effect on the history of controlled fusion experiments.

The most direct outcome of the announcement was its effect on Lyman Spitzer, an astrophysicist at Princeton University. Just prior to leaving for a ski trip to Aspen, Spitzer's father called and mentioned the announcement in The New York Times. Spitzer read the articles and dismissed them, noting the system could not deliver enough energy to heat the gases to fusion temperatures. This led him to begin considering ways to confine a hot plasma for longer periods of time, giving the system enough time to be heated to 10 to 100 million degrees Celsius. Considering the problem of confining a plasma in a toroid pointed out by Enrico Fermi, he hit upon the solution now known as the stellarator. Spitzer was able to use the notoriety surrounding Richter's announcement to gain the attention of the U.S. Atomic Energy Commission with the suggestion that the basic idea of controlled fusion was feasible. He eventually managed to arrange a meeting with the director of the AEC to pitch the stellarator concept.

Researchers in the UK had been experimenting with fusion since 1947 using a system known today as z-pinch. Small experimental devices had been built at the Atomic Energy Research Establishment (AERE, "Harwell") and Imperial College London, but requests for funding of a larger system were repeatedly refused. Jim Tuck had seen the work while in the UK, and introduced z-pinch to his coworkers at Los Alamos in 1950. When Tuck heard of Spitzer's efforts to gain funding, he immediately applied as well, presenting his concept as the Perhapsatron. He felt that Spitzer's claims to have a fast track to fusion were "incredibly ambitious". Both Spitzer and Tuck met with AEC officials in May 1951; Spitzer was granted $50,000 to build an experimental device, while Tuck was turned away empty-handed. Not to be outdone, Tuck soon arranged to receive $50,000 from the director of Los Alamos instead.

When news of the U.S. efforts reached the UK, the researchers there started pushing for funding of a much larger machine. This time they found a much more favorable reaction from the AERE, and both teams soon began construction of larger devices. This work, through fits and starts, led to the ZETA system, the first truly large-scale fusion reactor. Compared to the small tabletop devices built in the U.S., ZETA filled a hangar and operated at energy levels far beyond any other machine. When news of ZETA was made public, the U.S. and Soviet Union were soon demanding funding to build devices of similar scale in order to catch up with the UK.

The announcement had a direct effect on research in the USSR as well. Previously, several researchers, notably Igor Kurchatov and I. N. Golovin had put together a development plan similar to the ones being developed in the UK. They too were facing disinterest on the part of the funding groups, which was immediately swept away when Huemul hit the newspapers. |
