Comment Re:You could also use a non-critical reactor desin (Score 1) 170

All neutrons in a fission reactor are created via spallation ...

This is not correct, neutrons are produced directly as by-product of nuclear fission. Since the fission reaction produces more neutrons than it absorbed this can lead to a runaway chain reaction. The latter is by design in a nuclear weapon, but very much not wanted in a reactor, as it can cause an uncontrolled core melt-down.

If fission material is suitable small such a chain reaction cannot be entertained as to many neutrons escape (to be precise the ratio of nuclear fuel volume to surface area is what matters).

In conventional reactors the fission neutrons are slowed down by moderators to sustain the controlled chain reaction, but there's is also fast breeder reactors that can directly utilize the fast neurons to sustain the fission reaction.

Reactors that are driven entirely by external spallation neutron sources can use sub-critical amounts of fission material and still achieve a net energy gain. Since the can also process nuclear waste I view them as a crucial technology from an environmental POV.

Comment "financial news website" - is that a joke? (Score 3, Interesting) 154

ZH has been a major alt-right platform for years now.

It may have started out as a site focused on financial markets, but nowadays those kind of articles are few and far between.

When the Stormfront neo-Nazi site was shut down, its readers all moved to ZH.

The site's comment threads are a fever swamp of Antisemitism and racism.

The ZH editors are obviously in the Kremlin's pocket. Putin is always portrayed in the most favorably light. I've been monitoring ZH for years now to understand what the alt-right is up to. Given the obvious bias, there is no doubt in my mind, that the site's owners are financially beholden to Russia.

Comment Asked Vitalik Butarin about this (Score 2) 68

Couple years ago at a hackathon I had an opportunity to ask Vitalik this question.

His answer was a bit hand wavy, he essentially maintained that it wouldn't be too difficult to swap out the current crypto underpinnings for a quantum safe one (e.g. lattice based).

I am not familiar with the Ethereum code base, but given how long it took them to roll out SegWit, I am not sure that I necessarily believe that it'll be as simple as Vitalik made it out to be.
