This episode of "Tales of Tomorrow" isn't exactly subtle. On top of that, the main characters just don't behave rationally. Together, this makes this a weak episode--one that is clearly the product of the times.
A professor is planning an experiment that MIGHT give mankind tons of cheap energy forever...or it could kill everyone within seconds. He feels the odds are in his favor and ignores every attempt by every SANE scientist to stop the experiment. As a result, bad things happen! Clearly this show is about nuclear weapons. When the first atomic bomb was detonated, scientists weren't 100% sure it wouldn't blow up the planet---and the guy in this show is clearly meant to replicate that thinking. As a result of this and his unwillingness, you need to think that the show is NOT being subtle and is anyone THAT stupid?! The same material could have been covered in a much more realistic and thought-provoking manner. This one is just hard to believe and silly. Overall, a pretty weak episode of an otherwise excellent anthology series.
