As we've seen in the comments to my last two posts, cold fusion, or LENR, has many skeptics and some firm believers. Scientific American describes a film, The Believers:

The film documents the announcement of the cold fusion finding at University of Utah in 1989 through to the downfall of scientists Stanley Pons and Martin Fleishmann by sharing expertly edited TV news segments along with magazine and newspaper clippings. The story moves back and forth between these news stories and interviews with fervent believers and modern experimenters in cold fusion today as well as interviews with scientists who played a part in dismantling the cold fusion discovery. ...

My favorite take-away thoughts from the film were insights into science as expressed in the loose interplay set up in the film between Robert Park, an eminent physicist who made the announcement that took down cold fusion for the American public, and Edmund Storms, the older bearded gentleman in his sweater seen in the trailer, a physicist formerly with Los Alamos, who is a firm believer in cold fusion. The two, while on different sides of the cold fusion issue, both say true things about how science is done and the state of science in America.
