The Manhattan Project used two different methods to enrich uranium, cyclotrons/Calutrons and centrifuges.

The centrifuges took longer to build but were more energy efficient, and the Calutrons were easy to build but used lots of electricity.

After they got the centrifuges up and running, most of the Calutrons were scrapped, with the remaining ones being put to use making high purity isotopes for scientific research.

Nuclear waste has a huge variety of isotopes mixed together, and Calutrons are great at separating isotopes - this seems like a match made in heaven.

Why do we use complicated chemical methods for recycling nuclear waste instead of shooting particles through a vacuum and relying on their different masses to hit spatially separated targets?

This suggestion is to add a new type of magical creature to Minecraft, the leafy tree dragon.

As the name suggests, they visually resemble real world leafy sea dragons.

These tree dragons naturally spawn in the leaf canopies of most of Minecraft's forests, specifically generating *inside* of leaf blocks.

Leafy tree dragons magically "swim" through leaves, not suffocating from being inside of leaves.

They are neutral creatures that will attack you if you attack first, and drop "tree dragon essence" which can be eaten to become temporarily immune to being suffocating by leaves, and to let you clip through leaves as if they were air.

You can also feel Tree Dragon Essence to horses, donkey, mules, llamas and camels to give them with the same temporary effect.

Looking for stories featuring unchecked CelesteAI in worm, or characters from worm "escaping" their universe and getting optimized/ponyified.

The next car that James Bond drives should be able to change its color with a flick of a switch by being covered with a color e-ink display.

License plates too of course.

Maybe fake digital dirt?

Start with a piece of polished metal.

Use a laser to make structural colors on the metal in a suitable pattern for your label.

Vaccuform a thin sheet of plastic against the metal.

Peel the sheet of now colorful plastic from the metal, and use it to label your container.

If your container has a complex shape, shape the metal to be similar to it before lasering.

This idea is for a wind powered scooter, similar to a sail board, but much crazier.

We have two wheels, a platform to stand on, a pair of handlebars to steer the front wheel.

Behind the scooterer (land surfer?) is a vertical shaft spun by the rear wheel.

This vertical shaft spins a vertical axis vsp-style cyclo turbo propeller.

The propeller blows air rearwards, pushing the shooter forwards.

There are two and a half different ways the scooter can avoid capsizing from crosswinds - the rider can lean into the wind, or we can take advantage of the thrust vectoring ability of cycloturbines to blow air in the opposite direction of the wind gust, or both.

Thrust vectoring can be controlled manually/mechanically, or by a manually controlled servo, or by a PID controller controlled servo.

There might be a "brake" lever that makes the cycloturbine blow air forwards.

For nearly as long as we have had two parties, the Democrat Party was *mostly* conservative and the GOP was *mostly* liberal.

When Regan became president, many conservatives in the Democratic party switched to the GOP, and many liberals in the GOP switched parties to the Democrats.

What is the likelihood of some similar shift in the future making a sudden large change in the makeup of the dems and reps?

I saw an ad on Craigslist for a room for rent in New Rochelle for 750 a month - most of the other offerings in the area are for a thousand.

After I saw the room and liked it, the person who showed me the room asked me to send her the deposit by zelle.

I asked for a lease, and insisted on paying by check.

After the deposit check cleared she emailed me a lease, the lease wants me to pay a 35 dollar application fee, by zelle.

I happen to know that in New York State, the maximum rental application fee is 20.

This *feels like* a scam.

This crazy idea is for a lock whose two concentric cylinders do almost the opposite of what a normal lock's cylinders do.

In a normal lock the inner cylinder rotates inside of outer (stationary) cylinder.

In the opposite day lock, the inner cylinder remains stationary and the outer cylinder rotates around it.

The inner cylinder is bolted or welded to the lock body, and the opening in the lock body for the key is *not* circular, instead being a slot with the same profile as the key.

To open the lock, the user inserts the key in the slot, and flips an adjacent lever from "locked" to "unlocked."

The lever is attached to a dampener which in turn rotates the outer cylinder and opens the latch.

If moved sufficiently quickly, the dampener feels like an almost rigid connection.

If pressed for several seconds, the dampener will squish, eliminating tension on the lock cylinder.

No tension means no single pin picking.

I tried ti off and on, I unlatched the folding thingy to look at the bottom of the battery.

I have not yet looked at the underside of the bike where the wires go into the controller.

This crazy idea is fairly simple - each time the user squeezes either brake lever enough that it contacts the bike handle, the cable shortens slightly.

This suggestion is to have buried, ruined structures in the nether, reminiscent of the piglin horde structures in Minecraft Legends.

In addition to unearthing cool buildings, you would be able to use a brush on suspicious soul sand for Spore Trim, Hunter Trim, Bastion Trim, and blaze powder.

When you enchant a Shulker Box with the "Backpack" enchant, opening your inventory shows both your normal inventory and the contents of the Shulker Box, similar to what you would see if you had placed then opened the Box.

If you have multiple Shulkers with the Backpack enchant, only one's interior is used as an inventory expansion, selected the same way a bow chooses which stack of arrows to fire.

If a player picks up an item and their normal inventory is full, and they have a backpack enchanted Shulker, the item will try to go into the Shulker.

In addition to being able to like or dislike a post or comment, I want to able to mark it as funny 🤣, heartwarming ❤️, informative 💡, etc.

And maybe seasonal/holiday specific reaction like cold ❄️, hot 🥵, Christmas 🎄, etc

And time limited responses that wont occur again ever "you had to be there" responses - think of Minecraft convention capes.

I want to read all stories that feature a character whose power prevents video cameras, digital microphones, and other electronic sensors from perceiving them, while still letting humans and animals see, hear, smell, and otherwise perceive them.

I am currently reading Kindness is Punk Rock, and Mr Terrific seems like he would be classified as a Stranger based on how be describes how neither dragon nor saint can perceive him...

I want to read stories where a hero or villain is digitally invisible (like Mr Terrific), not through technology and smarts, but as their parahuman power.

Suppose that Americas Constitution had said - from the beginning - that "in any election, any eligible voter may vote for as many or as few candidates as he chooses."

This would have eliminated vote splitting entirely, and vastly reduced extreme partisanship.

Which election would have been the first to have a different candidate win compared with real history?

The suggestion is for Mojang to make a sequel to Minecraft Earth.

The biggest thing that made Minecraft Earth fail was the pandemic - which is over.

The second biggest thing that made it fail was poor monetization - Microsoft could get extra income by making contracts with business to get a kickback whenever a Minecraft Earth player played in their physical store.

Third, they over promised - they shouldn't have said the game will have live views of nearby players' builds without a timeline to build it.
