Constitutional protections aren't trumped by mere issues of governmental convenience.

What a nice gish gallop of unrelated issues. The attempted connection between stratospheric aerosols and Indian surface pollution is absurd.

Where is this, Poland?

It's as if Trump was looking for another way to tank the GOP in the fall election.

Literally an arc.

If India is experiencing large scale mortality from warming, they aren't going to give a damn about your concerns. They're just going to inject aerosols into the stratosphere.

Albedo modification (stratospheric aerosols) seems much cheaper than direct air capture, as a stopgap.

Most of the claims from nuclear opponents talk about lack of flexibility in nuclear without specifying whether they are talking about technical or economic flexibility. Dishonest nuclear proponents then interpret that in a strawman way, as

Calling BS on the last claim there. It's not realistic to do it in Germany with just batteries for storage (since something like Li-ion batteries are poorly suited for handling Dunkelflauten or seasonal storage). Throw in a very lo

It's straightforward. Consider what would happen (for example) if all the fuel in a reactor is compressed into a more compact configuration. In a thermal reactor, there's no problem, as there's now no moderator. There was m

Superconducting storage is inherently short term, as the capex per unit of energy storage capacity is rather high. I doubt it's competitive with batteries even for diurnal storage. It might have niche uses, for example smoothing dema

Bismuth leads to the production of polonium, which is extraordinarily dangerous.

> 5 years Be careful with these figures. I understand they start the clock later than the west does.

Fast reactors have an extremely serious potential failure mode. In a thermal reactor, reactivity is maintained by a carefully designed lattice of fuel elements and moderator. Disrupt this lattice and reactivity goes down. Thermal neutrons

The flexibility claim was always the same lie: that what mattered was technical flexibility, when economic flexibility wasn't there.

Solar also means all those data center jobs (and, really, many general industrial jobs) flow out to low population density red areas.

Nuscale wasn't a sodium fast reactor. Perhaps you phrased that poorly? Nuscale is a PWR.

I think storage (transport of energy in time) will beat transmission (transport in space) for users not constrained by population density.

Very long duration storage in my opinion is going to be thermal. Standard Thermal's approach seems very simple and promises to deliver 365/24/7 heat (ultimately sourced from PV) at 600 C for cost competitive with Henry Hub na

It's an argument against preprocessors for programming languages. Tree-sitter's error handling is constrained by its intended use in editors, so incrementality and efficiency are important. For diffing/merging, a more elabo

Well, if you're programming in C or C++, there may not be a parse tree. Tree-sitter makes a best effort attempt to parse but it can't in general due to the preprocessor.

AI takes a math textbook and translates all the theorems and proofs into formal language that can be checked automatically for correctness.

It's like the diesel engine, which is named after Rudolf Engine.

NASA does not seem to be constituted to be able to engage in a coherent manned space program of actual value. It's a long standing systemic issue. They are great at pretending to deliver value, but there's no "there" th

Even if Starship completely fails, SLS is a pointless and ludicrously expensive dead end. Terminating it is the only logical thing to do.

This sort of battery is well suited to smoothing wind output, which tends to vary on a multi-day timescale.

And there are reports they aren't lasting very long before cracking.

What we're seeing instead are companies you can send CAD files to, get estimates, and receive the parts back in a few days.
