5500 GwH seems to be the yearly batteries manufacturing capacities projected in 2030. That is what will be produced every year, not the total installed capacity of batteries. And as mentioned earlier those batteries could technically inject

Electricity storage is only one of the six elements I mentioned... When it comes to storage, thermal storage is cheaper and have a huge potential (and heat and cold represent about half of the US electricity consumption) Then batteries is o

Doing research makes sense (not just for nuclear). But current technologies seem enough to have a resilient cost effective grid without nuclear or coal (A diversified mixed of renewable energies with peak production higher than peak consump

My impression is that most people do not really care about other groups... unless it indirectly talks about something they are sensible, or they can clearly identify with the victims. For example people (and media) in France don't care

Some Uighur did turn Jihadist. Oppression and denial of resources in an area is perfect for radicalization, including Jihadist radicalization if this area/population is mostly Muslim. But so far, the vast majority of Uighur and Kazakh

Your comment could be read like: Muslim people "support" Palestinians because they are antisemitic... I mostly disagree. 1) While antisemitism was prevalent all over (including in Muslim countries) the world before Israel existed,

Why people in HN seems so (positively ) obsessed about nuclear and so indifferent when it comes to renewable energies?

SMR are not even at the toy pilots stage. We know the tech and we know it can work, but we don't when, what investment is required and if it will be competitive. A lot of uncertainty, but one tech only (with few different variations).

If you turn off the sound, most film suck and don't have their message passed across. Of course you don't have to show what you show, but then you make an entire different movie. The fact you could make a different movie, does not

Doing twerk in a movie when you are 11 years old and have support and context is not child exploitation. Especially given that twerk is a very small part of the actor work and of the film. And there is nothing supporting the idea that the f

The director said she did want to denounce over-sexualisation of young girls with this movie. I (and 2 of my friends, feminist women) think she managed to do it, with a relatively good and a relatively subtle movie. Talking about over-sexua

Battery prices (for different battery technologies) are currently in free fall, and the market is booming, so we are 100% sure to see important economy of scale there. This in currently not the case at all of SMR... When it comes to technol

There are a combination of different things. Firstly, better capacity factor for onshore wind, offshore wind becoming cost competitive and the emergence of floating offshore wind reduce a bit the intermittence, then the cost of managing it

But the fact is we have now cheap existing clean technologies, with a fast decreasing cost (decreasing cost of energy, and decreasing cost of managing intermittence)... It does not seems wise to bet that SMR will be cheaper than renewable i

SMR is interesting and have advantages... but it is not ready yet, and there are uncertainty about the cost. Wind and solar are getting so cheap that I have doubt SMR can compete on price... Possibly it could compete at the margin when the
