This idea is for a crossover between Naruto and Tenchi Muyo.

The home planet of Tenchi's Grandfather, Jurai, is the world of Naruto.

The various anachronistic bits of technology (electricity, tv, trains, motor boats) were salvaged or reverse engineered from crashed alien ships, or inspired by tales told by stranded aliens.

The rabbit-brained goddess, Kaguya Otsutsuki, is "just" an alien, not from another dimension.

Her sons, Hagoromo and Hamura, are perfectly aware that their mother has a chip on her shoulder the size of a planet, and are aware of her "anything you can do i can do better" attitude.

They immediately guess that the ten tailed monster is the result of their mother's botched attempt to create sage chakra.

When they defeat her, they try to separate the nature energy from her right away, without imprisoning her in Hagoromo.

After 9 attempts to separate the nature energy from their mother, what is left is an inanimate but living tree, the same size as the god tree was, but with their mother's face growing out of the bark.

The brothers don't know how to separate their mother from the tree, but are able to sense malice (killing intent?) from it.

Hagoromo makes an artificial lake to hydrate the tree and to act as a "natural" barrier to keep people away from it.

He then uses his Outer Path to make an artificial connection between the lake and the afterlife to continuously drain away malicious evil energies.

A couple thousand years later, the tree awakens, and is no longer evil, but no longer remembers her sons.

The tree takes a new name, Tsunade.

When an object moves through the atmosphere sufficiently fast, the air "in front" of it gets very compressed and very hot and, at hypersonic speeds, a plasma.

When air becomes a plasma, it becomes electrically conducive.

This crazy idea is to attach magnets to the outside of a spacecraft that will reenter the atmosphere, so that when it comes down, the movement of the magnets through the conductive plasma will generate circular eddy currents in the plasma.

These eddy currents will create magnetic fields with the opposite direction of the spacecraft-mounted magnets that originally made them.

This pushes the spacecraft upwards, slowing it down, even without physical contact between the super hot plasma and the magnets.

Ive read that when recycling old paper into "new" paper, a fifth of the fibers become too short to use.

How are those "too short" wood fibers separated from "long enough" fibers and what do they become instead of paper?

Are they landfilled, burnt, made into rayon/modal/viscose, made into nitrocellulose?

A biblio-decka.

Just as they transform blue sheep into red sheep, they should turn one type of blue block (lapis) into the newest type of red block.

Although the warranty for brake pads is officially a limited lifetime one, AutoZone treats it as an actual lifetime warranty with unlimited replacements, and they are usually unbothered by replacing worn out brake pads.

I assume the policy makes the part a loss leader, to get customers in the store and gain brand loyalty...

What are people's experiences with AutoZone's duralast brake pads?

When you burn a pound of diesel or gasoline, you create approximately a pound of water vapor.

This crazy idea is to cool some or all of the exhaust of a car or truck to condense a decent fraction of the water produced.

This water would then be used for old fashioned water injection, or, more crazily, so the engine can operate with six stroke (crower) cycle.

Water injection can reduce nitrous oxide emissions, and, in diesels, reduce particulates.

A six stroke cycle alternates back and forth between a four stroke otto/diesel cycle and a two stroke steam expansion/steam exhaust cycle - water is sprayed/injected into the cylinder at the beginning of the fifth stroke, absorbs heat from the valves and cylinder walls, and becomes high pressure steam.

This idea is for a crossover between Naruto and Tench Muyo, where the god tree of Naruto is the ancestor of the goddess tree Tsunami and the mystical tree ships of planet Jurai.

Princesses Kaguya could just be an alien from another planet, not an extradimensional alien.
