China is moving away from that as well. China did this because of the threat of capitalist invasion but the realize its dumb. Russia is a bit different and they couldn't really move it further east because it would be to far from their

One of Elon main points was that you can't have all these ships built in clean rooms by PhDs. You need a large number of workers, who can weld, move stuff around install stuff onto the rocket. The most difficult to produce things, like

You can not actually police that sort of thing. Thorium is literally everywhere in the earth core. You could basically dig hole right next to your fusion reactor and mine Thorium right out of it, expose it to neutrons and create Uranium-233

Arguably a fusion reactor has a much higher chance of harming the population around as a breach in containment could release highly radioactive gases. > But even with the low hanging fruit type of fusion with tritium & deuterium, you

Next generation fission does not need cooling towers. As soon as you go to a high temperature design, they can run perfectly fine in the desert.

Literally every country in the world has enough thorium in the ground for 100s of years. Go look up how much thorium is in the earth. You can literally go in-front of your house, dig a whole and in theory you can have enough thorium for a y

This is exactly my point, a properly designed molten salt thorium fission reactor is really terrible to build nuclear weapons (no nation would ever do it) and a Fukushima-style meltdown is literally impossible. The waste from a closed cycle

I'm not saying I don't want it. It just seems as humanity we totally fucked up. We found a revolutionary new energy source and we totally fucked up the deployment of it. We should live in a nuclear age already, fission powered spa

The chance of that happening with the fission reactors currently being built is almost vanishingly small. And even the largest nuclear accidents ever did not lead to anything close to that. This is just fear mongering nonsense. And btw, eve

Are you accusing him based on no evidence or what is your point her? Of course he doesn't have prove that something didn't happen.

I still don't understand why people want fusion. Like fisson already does basically what you need and is easier in every way. Yes, the energy density of fusion is higher but the energy density of fission is already so absurdly high com

There are many solutions for this. Corrosion is absolutely a problem you can find engineering solutions to. And Moltex has very elegant one. Other companions like Terrestrial are simply replacing the reactor core after 7 years. The MSR expe

You are not the first to think about this. You need to consider how freaking gigantic this thing is. It literally like a huge building falling out of the sky. That scale alone makes most of these solutions silly. Here for example NASA idea

My favourite current design is by Moltex Energy. Its basically, what happens if you take a Sodium reactor design and instead use molten salt. It basically fixes all the really terrible ideas about sodium reactors and gives you the advantage

The problem if nuclear power is that technology progress has slowed to almost 0 and we are still operating with 60s technology. In the 60s we built many, many test reactors and it was clear that nuclear power had huge potential to revolutio

There are a lot of different things that potentially can be going on. We had a couple things burn in the engine bay in the last couple test. What you are referring to however is most likely related to access gas. Starship starts up 3 engine

Everyday Astronaut will soon release a video with all the math about this. It turns out that even doing the flip slightly higher, already has a massive impact in terms of energy required. Slowing down from Orbital speed is an insane amount

Of course fuel cells have some applications but they are not exactly dominate in any of these. A large number of these are still small scale pilots and often mostly government financed. We have seen no massive adoption rate growth and we ha

The good thing about the first stage is that you can go 'ass' first and fly the rocket threw a corridor of relativity ok environment. The problem with second stage re-usability is that it is like 25x harder then first stage. >
