Let There Be Light was generally well-received during its world premiere at Austin's SXSW Film Festival. It raises some vitally important issues about the massive scientific endeavor of trying to develop nuclear fusion technology which if perfected could solve the world's energy issues almost overnight and end our dependency on fossil fuels. It is a tantalizing possibility that international researchers have been quietly working on for decades. The film raises some important and fundamental questions. It also examines some of the bureaucratic and political hurdles (including some utterly clueless members of the U.S. Congress) that have undermined the research.
Unfortunately, it also meanders a bit through different research projects without clearly explaining why the various scientific approaches really matter. While it is a fairly accessible introduction to the subject for a lay person, it seems to go off in too many different tangents. Much of the film is not particularly visually interesting with a lot of shots of scientific talking heads in laboratories. Still, this is an important research which needs to be funded and in a country deeply lacking in scientific knowledge that recently seems to be rejoicing in its own ignorance, the film is quite worthwhile. This important research has a better chance of being properly funded if more Americans at least gain a basic understanding of what fusion is and why it is so important. I hope the film gets distribution so more people can learn about this important research.
