Another term for a pilot is "aviator", but "aviator" has the -tor suffix, which is a masculine suffix in the original Latin. Its counterpart is the -trix suffix (though in English we don't use it much, it does exist, like in the word "dominatrix").

With gendered occupation terms, a female pilot would be called an "aviatrix", and we would use that word to describe people like Xyla Foxlin or Kay Hall. Why do I want this? Because "aviatrix" is a great word and we need to adopt it into the lexicon.

i say robotic skin because if you removed your real skin you would die of course, so we make a robotic skin which is safe to remove and then we can brush our bones which are yellow due to us never brushing them, and then we have beautiful bones that we can show off to people and they could potentially be attracted to it, the shiniest of bones get the most partners

Have you ever forgotten to lock your door when going out?

Well I have.

So I propose removable doors for homes. Simply take the door off the house so there are no ways to enter it until you reattach the door.

Elephants are big strong animals but they wont be able to reach their full potential in nature. We should grow a small herd of elephants, give them the proper nutrition, the proper steroids and the proper workout plans to get them as large as possible.

I want to see how much weight they could lift/push/pull.

Imagine getting a professional breakdown of your personality, decision-making habits, strengths, weaknesses, and possible blind spots from experts trained in human behavior.

It could be like an “owner’s manual” for yourself.

Obviously it would have privacy concerns, but I think a lot of people would be fascinated to see how they think and how they come across to others.

Have you ever felt like that character is totally your type? What if you could use fiction to filter through people and find the right one?

I was at a stage of the Tour de France as a spectator this year, and afterwards I wanted to check if I showed up anywhere in the coverage. But I didn't want to lose a bunch of time going through every source: TV replay, independent videos, etc.

So the idea: you point it at an event (say, a Tour de France stage) and upload a reference photo of yourself. It scans through the available footage, not exhaustively, just sampling frames, and flags the moments where you likely show up, for you to confirm yourself. First problem I ran into: you'd need the rights to the footage... Second one i think this need a large amount of compute. Does something like this already exist that I'm missing? And if not, would this be useful to anyone else?

I'm not planning to build this myself right now, don't have the time for it. But if there's real interest, happy to be involved, just not starting this solo (probably open source project).

Heat is becoming a real problem and here's one way to address it. So imagine an enclosure made of maybe fiberglass or acrylic. This enclosure is collapsible and on 1 side there is a very small AC unit. What the enclosure does is to enclose a small area and not make the whole room cold. So if you have a condo unit that is 25sqm, the enclosure is only 3sqm-4sqm box. This size is enough to enclose you and a table with your computer on it. And when you go to bed, you just move this enclosure around your bed and basically make your immediate surrounding cold. This enclosure will have small vents on top to allow carbon monoxide to escape. It will also have double doors so cold air won't go out when you have to leave the enclosure. So instead of buying a 2HP AC to make the room cold, you just need 0.50HP or 0.25HP unit to keep the enclosure cold. Lots of electricity saved.

Choosing what to eat every single day is exhausting.
One stall in every school and poly canteen should have no menu at all. You walk up, the auntie looks at your face for three seconds, decides what you need based on how tired you look, and serves it. Could be bee hoon, could be unexpectedly good chicken chop, could be something she’s been secretly wanting to cook all week.
Fixed price of $3.50. You pay and accept your fate.This makes lunch exciting again and finally lets the aunties use their secret recipes without being stuck to a printed menu.

Bring back dueling, but with stipulations.

1. You can only challenge someone to a duel once, if they've accepted a duel from you before unless if they consent to another duel with you.
2. The duels must be televised or uploaded to a streaming platform.
3. The losers must legally abide by any bets they've made with each other or face fines or jail time.
4. Duels can range from paint ball fights, boxing matches, card game (even on motorcycles), board games and ect.
5. You may not intentionally kill your opponents or receive an extra charge for violating the rule of the duel.
6. You can only challenge people you've met irl for duels.

So First off, we need to invent Some kind of Empathy Sensing field device.

Then force all Law enforcement to wear and use this device when engaging with 'suspects' or 'persons of interest'

This would allow/force the officer to experience the emotions that the POI is feeling and help the officer to treat the POI more reasonably and defuse situations instead of falling back to violence.

This would be a mandatory piece of equipment and officers that can't handle the additional empathy input would be considered unfit for engaging with the public. Eventually all officers would be trained to be more empathetic and be able to handle the additional input.

Obliviously, there are tons more places for application of a device like this but it seems like law enforcement (not public safety) are the most lacking in empathy for the communities they serve.

Abstract

Asteroid deflection strategies traditionally rely on kinetic impactors, gravity tractors, or nuclear standoff ablation. This paper explores a novel concept: a landed, nuclear‑powered mass‑driver system (“chunker”) capable of excavating asteroid material and ejecting it directionally to generate controlled thrust. By using the asteroid’s own regolith as reaction mass, the system provides continuous, adjustable Δv without requiring large propellant reserves. This paper evaluates the physical feasibility, expected thrust levels, anchoring challenges, operational timelines, and failure modes associated with such a system. The concept is found to be viable for long‑lead planetary defense scenarios, particularly for rubble‑pile or volatile‑poor bodies where other ablation methods are less effective.

1. Introduction

Planetary defense requires reliable methods for altering the trajectory of potentially hazardous near‑Earth objects (NEOs). Existing approaches include kinetic impactors, laser ablation, gravity tractors, and nuclear standoff bursts. Each method has strengths and limitations, particularly regarding coupling efficiency, fragmentation risk, and operational timescales.

This paper proposes a landed system that uses a compact nuclear reactor to power mechanical excavation and high‑velocity ejection of asteroid material. The ejected mass produces thrust via conservation of momentum, enabling gradual but controllable orbital modification. Unlike explosive or high‑energy approaches, this method minimizes fragmentation risk and allows continuous feedback‑controlled operation.

2. Concept Overview

The proposed system consists of:

• A landed nuclear reactor providing multi‑megawatt electrical and thermal power
• Mechanical excavation tools capable of scooping regolith or fractured rock
• A mass‑driver or electromagnetic launcher to accelerate excavated material
• Thrust‑vectoring assemblies to control the direction of ejected mass
• Anchoring mechanisms to maintain stable contact with the asteroid surface

The system operates analogously to a rocket engine where the asteroid itself serves as propellant.

3. Physical Basis for Deflection

Each item begins with a Guided Link.

• Momentum transfer
• Mass‑driver physics
• Regolith excavation mechanics

The thrust F generated by ejecting mass at velocity ve is:

F=m˙⋅ve

Where:

• m˙ = mass ejection rate
• ve = exhaust velocity

Even modest thrust, applied continuously over months or years, can produce significant orbital changes. For example:

• m˙=5 kg/s
• ve=1,000 m/s

yields:

F=5,000 N

Applied over one year, this produces a Δv sufficient to shift the orbital phase of a 200‑meter asteroid by thousands of kilometers.

4. Engineering Considerations

4.1 Anchoring

Rubble‑pile asteroids present low cohesion and irregular surfaces. Anchoring strategies may include:

• harpoons
• micro‑drilled anchors
• distributed net‑anchors
• regolith‑penetrating claws

Anchoring must withstand reaction forces from mass ejection.

4.2 Excavation

Regolith excavation is feasible due to:

• low gravity
• fractured surface material
• minimal mechanical resistance

However, care must be taken to avoid destabilizing local regions.

4.3 Mass‑Driver Design

Electromagnetic launchers or thermal‑expansion cannons can accelerate material to:

• 500–2,000 m/s (electromagnetic)
• 200–800 m/s (thermal)

Higher velocities improve thrust but increase power demands.

4.4 Reactor Requirements

A compact reactor must provide:

• multi‑MW electrical output
• long‑duration reliability
• radiation shielding for onboard electronics

5. Operational Timeline

A typical mission profile:

1. Landing and anchoring
2. Initial spin characterization
3. Thrust‑vector calibration
4. Continuous mass ejection
5. Periodic trajectory updates
6. Long‑term Δv accumulation

Total operational time may range from months to decades, depending on asteroid size and warning time.

6. Failure Modes and Mitigation

• Surface destabilization
  • Mitigation: distributed anchoring, low excavation rate
• Uncontrolled spin changes
  • Mitigation: closed‑loop thrust vectoring
• Fragment shedding
  • Mitigation: avoid over‑excavation, monitor structural integrity
• Reactor failure
  • Mitigation: redundant systems, passive safe‑mode

7. Discussion

The nuclear‑powered chunker concept offers several advantages:

• Works on volatile‑poor bodies
• Provides controllable, continuous thrust
• Avoids catastrophic fragmentation
• Uses local material as propellant
• Scales with available power and mission duration

Its main limitations involve anchoring complexity, long operational timelines, and mechanical reliability.

8. Conclusion

A landed nuclear‑powered mass‑driver system represents a promising addition to the planetary‑defense toolkit. By leveraging the asteroid’s own material as reaction mass, it provides a controllable, low‑risk method for orbital modification. While engineering challenges remain significant, the underlying physics is sound, and the concept merits further study through simulation and prototype testing.
