I don't know why no EV manufacturer has thought of this:

Build a small generator / fuel tank into a TRAILER that you can hook up to your EV. This gives you the best of both worlds: for short, around-town trips, you leave the range extender trailer at home; but, when you want to drive long distance, just hook up the trailer and you can travel an arbitrarily long distance. Given the incredible efficiency of EVs, it's likely that a well-designed range extender trailer could give you several thousand kilometres of range.

Revolutionary Scuba Mask Creates Breathable Oxygen Underwater On Its Own 375

schwit1 writes "With the Triton Oxygen Respirator, it might be possible to breathe beneath the surface of the water as if you were a fish. Requiring no bulky tank to keep your lungs pumping properly. The regulator comprises a plastic mouthpiece that requires you to simply bite down. There are two arms that branch out to the sides of the scuba mask that have been developed to function like the efficient gills of a marine creature. The scaly texture conceals small holes in the material where water is sucked in. Chambers inside separate the oxygen and release the liquid so that you can breath comfortably in the ocean."

An historic X would be correct (the adjective starts with a vowel). So would an eulogy (y is really a vowel, in this case).

In both cases, I disagree, because it's just dumb. But that's the rule ... can we change the rule?

Sorry, wrong. The 'correct' grammar as taught to me in school was to use the definite article 'a' when the noun referred to starts with a consonant, and 'an' when the noun starts with a vowel. Critically, this rule *regards 'H' as a vowel*, leading to the correct usages:
  An hero
  An hotel
  An hovel

Personally I think it's dumb to regard H as a vowel in this context, but that's what I was taught.
