Factual error: In a radio news voice-over shortly before the first chase scene, the newsreader comments that "Calls have flooded in from all over the world regarding Dr Barkley's research." He then goes on to mention that the Royal Academy in England has expressed an interest. The "Royal Academy" is more formally the Royal Academy of Arts. They probably mean the Royal Society, which is the most important scientific institution in the UK.
Factual error: In the scene where Keanu Reeves breaks into a house (after the snowmobile chase) he kicks a door in. When any door is broken down in this way, the lock either breaks or is wrenched out of the door. However, when the door swings shut behind Reeves, there is an audible click as the latch closes again.
Factual error: Energy is released when hydrogen is burned in the presence of oxygen, and water is formed. The premise of the movie is that near infinite energy is released when water is split into hydrogen and oxygen is false. Energy is consumed in that reaction.
