Usually when I go to open a hood after an engine is running for around 30 minutes to an hour or more it's really hot. And I often burn my fingers trying to open the hood. I don't know if it's been invented yet but I would love it if someone would invent an automatic hood opener. And when I go to check the oil or transmission fluid, the plastic is burning hot. Maybe they could make something that doesn't absorb so much heat so you can grab it without burning yourself.

So your battery died and no one is around to help you jump start your car? How about a generator you crank for 10 minutes of power? You might be cranking the thing for 5 minutes at like 30 Revolutions per minute, but hey, it beats being stuck on the side of the road with no a/c or heat.
