My dog then made some of this.. Pardon my ignorance, what's its number in the periodic table?

Wow, that's hot. I wonder how many years this disc (3kg?) can power the Bitcoin network.

Wow, that's hot. I wonder how many years this disc (3kg?) can power the Bitcoin network. not too long, I guess. According to wikipedia, 1kg u235 can be converted into up to 52MwH usable energy, which means we have about 150MWh here. the btc network is currently at almost 13 TH/s, and given an average efficiency of 2 MH/watt, the bitcoin network is using about 6.5 GWh.

You mean 6.5GW right? That would mean the bitcoin network can be powered for almost 24 hours by a 3kg disc of uranium.

I hope we're done building uranium reactors. Thorium otoh is much safer and only requires a tiny amount of uranium/plutonium as a neutron source. They are fail safe and you can cut the power and walk away without releasing any radiation.

Nuclear weapons have, by necessity of delivery, a relatively small amount of nuclear material. Nuclear power plants have, on the other hand, many many tons of the stuff. In lots of cases, several loads of spent fuel sit outside of any hardened containment on the roof of the plants. And these tend to be pretty close to industrial and populated areas since that is where the power is needed. One thing that Fukushima opened my eyes to and which I did not know was that the GE Mark-I reactors, at least, are certain to melt down and explode if somehow they are without power for a certain number of hours. So if a somewhat capable adversary can figure out how to sabotage a few diesel generators and can drop a few high-tension power lines, we can kiss bit parts of our Eastern US goodbye (or more likely, plan on high rates of poor health among the 99%ers who will remain in the area.) Thorium reactors sound nice, but there is full court press to extend the life of our GE Mark-I's out an extra 20 years. Another thing I learned thanks to Fukushima is that if a nuclear expert says that something is 'impossible', what that actually means that said thing is either inevitable or has already happened. So, it will take some convincing to get me to believe in the miracle of thorium reactor safety.

So, it will take some convincing to get me to believe in the miracle of thorium reactor safety. Below the reaction vessel is a cooling system that freezes a plug in place. If the power fails, the molten thorium will melt the plug and drain into containment vessels, where it will cool since it is now away from your neutron source. All that remains is the neutron source, which is a very small amount of uranium. Far from enough to cause a melt down. I won't say it's perfect, or completely safe, but the fact that it has been proven to be safer than popular designs makes it hard to accept the fact that those same old designs are still being pushed while Thorium is being thrown under the bus. Oh well, maybe when India gets a third of its power from Thorium by 2050 as they are projecting we might sit up and take notice. Hopefully we don't have a catastrophe before then.

220 MWh / 6.5 MW, that's 34 hours/kg. The Bitcoin network is eating 0.7kg uranium every day.

I can't find the link now; but I read that the only reason the world's nuclear scientists went with a uranium design instead of thorium (and continue to do so today, despite it being common knowledge that thorium would be safer/better) is because you don't get any weapons grade byproducts out of a thorium reactor.
I can't speak to the truth of that; but it doesn't sound outside the realms of possibility.

Indeed, a majority of 'nuclear energy' programs seem to be designed with the requirements of building a nuclear weapons capability as well. I've heard it conjectured that we in the US have such a darn difficult time burying our spent nuclear waste for this reason. Also that the graphite core reactors of the USSR were particularly good at generating plutonium. I've also heard it said that Japan was burning MOX fuel in Diachi #3 primarily as an excuse to be extracting and generally dealing with plutonium. Since they are, in theory, a non-nuclear weapons holding country, they needed an excuse to be extracting and refining Pu. Even the US won't use MOX due to the hazards (so I understand.) Diachi #3 is the one which had the impressively big bang and spread fuel rods all over the place, and now Japan has plutonium all over a fair fraction of their territory including some of the most productive farm land. It is not clear to me yet whether those rods came from the reactor core of from the spent fuel pools (or both), but both had MOX fuel rods. Japan even sent me on the West Coast USA a little gift of some plutonium fuel fleas. Thanks a bunch! See you in hell Tepco and the lying, corrupt Japanese government.

We still have a very fractured market after the weak close of the stock market. At least a sharp short term decline is going to happen very soon.
