SciFi movies and pathetic misconceptions of tech failing for the story line.

Good sci-fi doesn't break physics (or chemistry, or anything else we understand well). It does, however, always make the assumption we have been able to work around an apparent obstacle we face today. Are you unhappy about them travelling to far so fast, with no apparent FTL technology, or they way the ships often moved in space like they were using wings against an atmosphere? I'm OK with the FTL issue. The stories won't work unless they can actually get around easily. The latter always makes me cringe.

They were not supposed to be the sharpest tools in the shed. Being a bunch of hapless crooks who thought they were the galaxy's master criminal was at the heart of the series.

No, the most likely scenario is the charger's transformer may fry itself, but secondly what will happen either way is the charger's diodes will fry to a short, shorting out the battery, thus making the wiring between charger and battery slowly burn up so long as there is enough charge in said battery to do so and there is no fusing between the battery and charger's bridge diodes.

You don't even really *need* the glow plugs anyway. Squirt a spritz of ether or even just gasoline or WD40 into the intake of an old diesel and you can start it without the glow plugs.

I still get drawn back to 'This Island Earth', where the hero's parts order is intercepted by the aliens and they send him a little bead capacitor that vastly exceeds the voltage rating of his big, metal canned, Paper in Oil one to pique his interest. :D

This Island Earth is a pretty good movie. It has lots of nice little ideas in it like that. The overall story arc is weak, but the little ideas make it very watchable.
