Yep. SMR is a much better drop-in replacement for fossil sources than renewables (generally stable/controllable output, dense locating so no expansion/upgrading of grid required unlike solar and wind, and can provide large winter

My small press pot actually makes around 12 us fluid ounces of coffee at the strength I like, with a fairly thick filter bed. Almost identical shape and dimensions as an aeropress, so it works interchangeably in that regard. I agree, would

Yes, but if you have a two year old iPhone then they give you a $300 credit for trading it in. And you're already paying $95 a month (to cover your two year old phone), so the monthly cost ends up being the same. And the only alternati

That's fair, I just find that the number of people who fall into that specific source of "spending too much" makes it important to specify. Most providers bury the actual phone cost somehow, and only focus on the monthly tota

Not really 6 times - 3.3 to 12.6 billion is about 4 times. Regardless, Finland started a similar project with the same design around the same time, and they're operational. China, too, started building reactors of the same design aroun

Note that's a peak rate, and that should be 100Gb (12.5 GB). Without knowing the variability it's impossible to say if that's a problem or not.

And in a typical year, France generates 72% from nuclear and exports lots of power to the rest of the European grid. There are serious issues to resolve, but that's why you interconnect grids. The real issue with Frances nuclear reacto

Seeing how debatable the issue of deaths caused by actual nuclear disasters is (varying from 400 to 60000 for Chernobyl), I can't imagine how little agreement two parties could have on the comparative amounts of human suffering caused

Right. I didn't mean to focus on it being safer, but rather just the blanket statement "no it's not" that I was replying to. It doesn't really matter to me, we just need to get off fossil fuels now

Note that they don't use 100 as the Chernobyl deaths estimate, they use 433. While I think that is very optimistic, there are very valid concerns with estimates made using the linear no-threshold model (which they discuss). And they
