  • Meh that may be true in some ways, but not really in this case. RTGs were made using a surplus from production for nuclear bombs. As that production ramped down combined with better solar and batteries, the demand went down and it became more expensive to produce them. So not making them made sense.

    An RTG is really only useful for missions that go far away from the Sun, making solar non-viable. RTGs are a pain in the neck all throughout the process, are heavy and expensive (even back in the day). The amount of electrical power an RTG delivers is also very low. This is because an RTG only gets warm, nothing more. So we put TEG (Seebeck) devices on the sides to generate electrical energy from the thermal gradient. But TEGs suck ass, they are super inefficient. For example the RTG the big Mars rovers use put out 2000W of thermal energy, but they manage to get only 110W of electrical energy out of that. So if you are near enough to the Sun, solar is the much better option.


  • Who has nuclear diamond batteries? Those are a total myth drummed up to get investor money. They don’t actually exist.

    Sure the concept exists, in the form of betavoltaic batteries, those have been around for decades. They are tough and last dozens of years if not longer. The only problem is, they put out microwatts. You can use them in very niche applications, but those are few and far between. It’s hard to convey how little power a microwatt is, it’s basically nothing.

    What you care about when going to space is energy density, and the proposed energy density of nuclear diamond batteries is very poor.

    Rtgs are very useful for longterm missions, but are crazy expensive. They also aren’t being made anymore, so getting a hold of one is hard. The weight is an issue as well, they are super heavy.

    These commercial moon missions are primarily demonstrator missions. They aren’t meant to last, they don’t really have a goal and often don’t do something useful. The idea is to show you can do it, so you can sell a product. Other people that do want to do useful stuff can then pay to get their stuff to the moon. So if the mission is over when the sun sets in two weeks time, that’s perfectly fine.





  • So you go to the doctor to get a medical license so you can fly an airplane. The doctor asks if you have any physical issues, you say no. Then he proceeds to ask you about your sex life. And not just a single yes or no question, he goes into great detail asking question upon question.

    This is seriously fucked up, a doctor could lose their license where I live asking stuff like that. Like my man you are supposed to see if someone is medically fit to fly, not if they live up to some standard of how women are supposed to behave from the 1800s.

    The whole don’t seek mental healthcare ever or you’ll lose your license is also just crazy. I think Mentour Pilot made some videos about that as well.

    Iirc this one featured mental health issues among pilots https://youtu.be/988j2-4CdgM




  • do u think that yoshi gets embarrassed when he poos out eggs in front of mario??? sorry if this ofends anyone but i thought it was a funny thing haha. and i would like to know if any of you have any pics of yoshi pooping an egg while he looks nervous or embarrassed i just want to see it for a few laughs haha. another thing i am wondering is what do you think the eggs smell like haha im just curious for laughs haha i would like to smell them





  • Agreed, building a nuclear facility takes a lot of time and costs a lot of money. However… This doesn’t need to be the case at all.

    A lot of the costs go into design, planning and legal work. The amount of red tape to build a nuclear plant is huge. Plus all of the parties that fight any plans to build, with a heavy not in my backyard component.

    If however a country would be prepared to cut through the red tape and have a standard design developed for say 10 plants at the same time, the price and construction time would be decreased greatly. Back in the day we could build them faster and cheaper. And these days we build far more complex installations quicker and cheaper than nuclear power plants.

    The anti-nuclear movement has done so much to hold humanity back on this front. And the weird part is most people do think nuclear fusion plants are a good thing and can solve stuff. But they have almost all of the downsides nuclear fission plants have in terms of red tape, complexity and cost.
