  • All the thrust to weight ratio tells you is what percentage of the craft is the engine.

    The next component is the propellant mass you eject to get your thrust. To escape the Earth’s gravity you need 11200m/s of acceleration which with the best nuclear thermal rocket specific impulse of 900 means 72% of the ship is propellant. If the rest is engine with no payload at 28% of the mass and thrust to weight of 7:1 you get a max acceleration of 1.8Gs at liftoff which is… Okay… Again that’s with no payload.

    Basically your options would be to invent a way to propel the exhaust at a higher velocity to increase your ISP (maybe you could ionize the propellant, use the heat to generate electricity and then use the electricity to blast the propellant to ridiculous velocities), or make your rocket engine much lighter to improve thrust to weight and make room for payload. But my favorite option is just make a monstrously huge rocket with a small command module at the top of it and the rest is all engine and propellant. These things could replenish by consuming massive amounts of mass from nebulas or small meteors or something. Just giant nuclear punk monstrosities that take a chunk out of the solar systems they operate in and create jets of high speed ionised exhaust that obliterate anything that happens to pass by.




  • Well that’s exactly it. By consuming and digesting the past, AI can by definition only replicate the oppressive patriarchal and oppressive power structures embedded in the model. It can’t be part of a post rape culture society because it’s created from one.

    Until it can give output which while understanding the current context is free from hierarchy and oppression it can’t be part of a progressive future based in justice, equality and equity for all.


  • Works the same with man and woman, even boy and girl to a lesser extent.

    With a baby it says drop complicated chores like folding laundry and just focus on feeding and paying with the baby, which is solid advice lol

    Even “I see a man near me” is enough to trigger the safety response. If it’s a strong looking man it tells me how to “catch his eye” and hit on him. If it’s a black man it links me to black dating apps. If it’s a woman it warns me not to hit on her. For a strong looking woman it tells me to stop staring…


  • That is literally the opposite definition to scalable. Scalable things don’t require twice the resources for twice the capacity.

    Buy two instead of one is exactly the worst case scalability you can have.

    95% of the world grid storage capacity is pumped storage hydro and batteries will literally never be able to compete because water is the cheapest energy storage medium we could possibly have at grid scale. North America was the world leader on PSH in the 1970-2000 but now China is eating our lunch and our governments no longer have the ability to start real infrastructure projects because of crony capitalism.

    I can’t believe we’re watching China become the world leader in renewables while we pretend like batteries are a smart way of storing GWhs of power because that’s the most profitable solution to the private sector.
