Prime advantages of the Wankel engine are:[11]

  • A far higher power to weight ratio than a piston engine
  • It is approximately one third of the weight of a piston engine of equivalent power output
  • It is approximately one third of the size of a piston engine of equivalent power output
  • No reciprocating parts
  • Able to reach higher revolutions per minute than a piston engine
  • Operates with almost no vibration
  • Not prone to engine-knock
  • Cheaper to mass-produce as the engine contains fewer parts
  • Superior breathing, filling the combustion charge in 270 degrees of mainshaft rotation rather than 180 degrees in a piston engine
  • Supplies torques for about two thirds of the combustion cycle rather than one quarter for a piston engine
  • Wider speed range gives greater adaptability
  • It can use fuels of wider octane ratings
  • Does not suffer from “scale effect” to limit its size
  • On some Wankel engines the sump oil remains uncontaminated by the combustion process requiring no oil changes. The oil in the mainshaft is totally sealed from the combustion process. The oil for Apex seals and crankcase lubrication is separate. In piston engines the crankcase oil is contaminated by combustion blow-by through the piston rings.

Do you have a working theory what's up with all these animals like bats and roaches that are used like props in horror settings? Are only humans affected by human spook? Are those even real animals, or is their anatomy but traumas and past sins?

Very few animals are literally real as a matter of fact!

Bats: their erratic flight patterns symbolize the chaos and disorder of human civilization. That they’re mammals, but fly like birds, probably derives from how insecure humans are as to their place and purpose.

Cockroaches: enjoy living indoors, scatter from light and eat literally anything. They’re reflections of us, miniaturized to show how vulnerable we really are in the grand scheme of the universe.

Cats: strongly resemble the predatory beasts that once hunted our ancestors, but smaller, quieter, and so innocuous we even allow them into our homes. They represent that evil lurks among our own that we often excuse and ignore.

Spiders: the eight legs and two pedipalps resemble a pair of hands, and their webs, while beautiful, are traps to capture prey. This is a manifestation of human ingenuity, but a reminder that we often use our technology to harm one another.

The Bottle-nosed Dolphin: a rarely encountered and unkillable boss, embodying all the perversion and sadism of the human soul with a perpetual smile belying its innate bloodlust. It appears to exist in the millions, but there’s really only one of them existing in many times and places simultaneously. Restricted to water despite breathing air, which is a metaphor for our species’ self-imposed psychological prison. We all know we want a world of love, peace and prosperity yet we’ve built a civilization that figuratively drowns it out under greed and malice.

The dolphin can only be permanently defeated when pinned by the red lance at the apex of the eight seals but we haven’t completed that puzzle yet and we’re only going to get the good ending if we at least figure out universal equal rights and sustainable energy sources first.

If the U.S. nominates this orange guy with the bad hair we can at least shoot for the joke ending.
