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.

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.
