Eureka

Invincible - S1-E5

Factual error: Henry Deacon says people only use 10% of their brain at any one time. That's complete garbage - at times we may use quite a small part of our brains, other times the whole brain lights up with activity. The "10%" myth has absolutely no basis in fact - no-one even seems to know where this figure came from! Given the intelligence of Eureka's residents, Henry (and indeed others in the room) would know this.

Phased and Confused - S3-E6

Factual error: Zane used ULF (Ultra Low Frequency) to communicate with Henry and notes he can "only send numbers." This is a reference to extremely low bandwidth of maximum 300 Hz transmission. However, later Henry magically creates an upgrade that allows voice communication - not possible with ULF. Also, no way Sheriff's old radio would pick up ULF band communications in the first place.

This One Time at Space Camp... - S4-E18

Plot hole: When Dr. Hughes is racing to save Allison when he thinks he is Carter from the events that happened in "I'll Be Seeing You" Henry says he is racing for a cliff, and that the cabin was just a hologram. But in the episode the Cliff was the hologram disguising the cabin. Henry even commented in that episode that he did not remember a cliff being there.

Just Another Day... - S5-E13

Trivia: In the final scene, as Jack and Zoe are heading out of Eureka, they pass their younger selves heading into Eureka. This scene is from the pilot episode where Zoe sees another version of her and her dad. However, in the pilot episode, the other (older) Jack and Zoe are in Jack's original car, not his Jeep, and other Zoe waves at them. I would call this a mistake, but I'm listing it as trivia because I know someone would say "after they came back from 1947, things changed so this changed too."

Chosen answer: He's still around, we've just not seen him lately, as scenes with Blake have been mainly at work, where Kevin wouldn't be.
