Re: TOS Microtapes: help me settle a debate!
"If we want to talk about dated technological assumptions in TOS, what gets me is Kelso's line in the second pilot about the impulse points decaying to lead. That would mean the "points" were made of uranium and the impulse drive was fission-powered, instead of fusion-powered as is now assumed."
But...in this particular, same pilot they arrive at a "lithium cracking station" (Delta-Vega). One of the components in our (still) theoretical designs for fusion reactors is "cracked lithium".
Thus it would appear that they were aware of fusion power unless it's a collossal coincidence.
