Thanks for taking the time to think about it - very helpful comments. Will check FenBen out and stick some references in as I find them again.

Do you have a better resource or recommendations? I'd be happy to remove this from the internet. I feel that most other articles on the topic would be severely self-censored because of the small amount of research and the risk you ment

I worked on this and host it on my site as well where it's not parceled up into bits and pieces. Have to thank Bartosz Ciechanowski. Learned a lot from his code and approach. https://lvenneri.com/nuclear_reactor_explain

nah you can just create little holes in the sphere to illuminate the planets. negligible power loss. Earth and all the planets live on the sun's crumbs, no the (crumbs of the cumbs)^12

I like the railgun analogy. I think you can stock up on other fusion cost arguments through my article, Engineering and Economic Challenges of Fusion: https://lvenneri.com/blog/ConFusion

They will have two types of reactors. First, large centralized reactors for DD fusion to make He3. These will be more expensive and challenging because of the neutron bombardment. The other for D-He3 fusion which will be for smaller sites a

Doesn't matter if the heat is coming from burning more fossils or nuclear fuels or intercepting more solar light - the effect on Earth's temeperature is negligible for now. You can do simple heat balance with Stefan Boltzman Law t

Main problem is the rock melting temperature ~ 1500 to 2000 °C. Even the best performing nuclear fuels can only reach 1600°C in the fuel (TRISO Particle or FCM fuel) for limited periods of time, meaning 1000°C of heat delivered due to major

Not exactly. Nuclear reactors have a difficult time following the load because of Xenon poisoning. Xenon generated during the fission reactions absorbs neutrons that could have been used for fissions. Luckily, it decays away over time. If y

Probably the same or longer. In fact, the NuScale concept has been pursued since 2002, so more like 2 decades from concept to NRC certification. And you can tack on another 10 years for their hardware demonstration according to their publis

Yes interesting. There are also good reasons to build cities in circles/squares. 1. Minimize the perimeter to area ratio. This minimizes the interface with the outside, such as protective walls and access points. On the other hand, in

Great idea! US DOD budget: 700B. We only really need nukes to keep the peace and maintain our interests. Nukes cost 20B/yr to maintain (both stockpile and delivery methods). The rest of the military budget is a bunch of garbage whose a

Fusion is generally touted by many as an energy "Holy Grail." Indeed, it appears to have similar qualities, being both perpetually elusive and miraculous, able to solve all mankind's problems. Media reporting tends to discuss

This is not true. Fission reactors have to deal with decay heat, not fission reactions when cooling is lost. This can be managed. Fusion reactors also have decay heat. In new reactors like the Micro Modular Reactor, it's actually less

You're better off donating money to fusion companies directly than paying taxes to the government. Wish musk had donated his taxesto companies last year instead.
