I think the real advantage would be for transpacific flights. San Francisco to Tokyo is currently about 11.5 hours, assuming a similar ratio (maybe slightly better due to flying supersonic for longer), Boom’s time would be around 6.5 to 7 hours. Savings would be more significant for East Coast flights, ATL-HND would go from 14.5 hours to under 8.5.

But the severity of Chernobyl definitely fomented anti-nuclear sentiment much further than it had been. It “showed” that a major radiological release could happen in a civilian power plant (nonwithstanding that such designs weren’t used in Germany). Ultimately the formation of the sentiment was a process, of which Chernobyl is a core part.

1. Being on the front lines of the Cold War, in the event of a hot war, most nuclear weapons would be used in West Germany. (Yes, weapons aren’t power plants, but they can be hard to separate in popular discourse.)

2. Plans to build a nuclear power plant at Wyhl were opposed by locals, who occupied the site, and were forcefully removed by police. This was broadcast on television and helped galvanize the anti-nuclear movement.

3. The Chernobyl accident led to fallout being deposited on German soil, which furthered opposition, and in my view, was the killing blow.

DC has an advantage in newness and in materials selection (tiny tiles with lots of grout looks cool for 5 minutes), as well as having relatively fewer station layouts.

This is a real disappointment. My most recent Best Buy purchase was a PS4 copy of GTA V to give as a gift. I’d previously purchased several movies from them. I liked being able to buy these items in person, without having to worry about damage or getting scammed.

As a blank check, sure. But there are specific regulations that could be removed. For example, the U.S. prohibits automatic load following equipment in nuclear plants, while the French allow it. It would allow for a control room operator to not have to constantly micromanage the reactor.

Quantity. One of the big issues with nuclear power is that we aren’t building frequently enough, and therefore lose expertise and capability, which drives up costs, both from screw-ups and from not being able to amortize over a large production run. To give an analogy, imagine if Boeing only made one 737 every five years. That aircraft would be insanely expensive.

Personally, I’m bullish on the companies in the micro reactor space that have minimal site construction. I’m less bullish on Oklo, given that their application had some glaring omissions and got denied an NRC license.

Yes, you can have the reactor offline, with control rods inserted for launch. Then when you reach the requisite altitude, withdraw the control rods and start up the reactor. In the event of a launch accident and potential destruction of the reactor, the enriched uranium fuel would be a chemical hazard (uranium is a heavy metal like lead), but only a mild radiation hazard (since there are no high-gamma fission products, and the uranium has undergone heavy purification prior to fuel fabrication).

Hypothetically, if the technique can enrich U, Pu, or other fissile isotopes in decent quantities, you run into other issues. Stirring an aqueous enriched uranium solution is a great way to have a criticality accident (cf. https://en.wikipedia.org/wiki/Criticality_accident). That’s not to say it’s impossible to manage, just difficult. UF6, the current compound of choice for enrichment, is in the gas phase during the process.

It’s still a point source, and thus cheaper and easier than direct air capture. I don’t think it will be as significant as some think it will be (we will likely move toward different processes for the remaining limited petrochemical production), it is likely to still be important for some industries.

Is there any way to link up which designer works with which contract manufacturer (or at least the models)? And are there any exceptions? I seem to recall Alienware stuff was made in Florida at some point.

The 1972 ban was in the United States. It wasn’t global, and even the Stockholm Convention allows for vector control using DDT. In any case, starting in the 1960s DDT-resistant mosquitos began to emerge, so continued non-targeted spraying likely would’ve become ineffective sometime in the 1980s.

Tough to say. Not all countries have total bans on DDT, and even the Stockholm Convention exempted vector control from the ban on certain organochlorine compounds. In any case, DDT-resistant mosquitoes were already starting to occur in the 1960s due to the unrestricted spraying. Spraying has mostly continued as indoor residual spraying, which still seems to be quite effective.

Interesting, what made you go for wood fiber insulation versus something like ICF?

Also, UK or Canada? Noticed the spelling difference.

I’m curious to hear about what you did with the house (I’m thinking about building/renovating a house in a few years). Did you go DIY or hire a contractor? What were some of your replacements for plastics?
