  • Self hosting email is horrid. Well self hosting email is not that hard now with Stalwart and other servers in a box exist. But getting your email accepted by any remote server require a fair amount of work.

    The best alternative I have found to Gmail is Fastmail. They now offer EU hosting. Proton would have been an option too but they’re losing the plot.

    Fastmail is genuinely the best web client I’ve come across. I have to use Gmail for work so I know it well and compared to Fastmail it’s basically Slowmail.








  • Storage isn’t a technological problem anymore?!

    Let’s take a country like the UK, which is well ahead in the renewable transition compared to most other countries. In the last 3 years we’ve had 619 periods where renewables covered less than than 50% of our mix, the longest lasting 19 days (October-November 2024), where the average cover was 16%. Let’s work out on the basis of just that single dunkelflaute as an instructive example.

    To see us through that period Britain would have needed 12 TWh of storage. How much is that? Well, we have 0.04 TWh of total storage, across pumped storage and batteries (pumped storage almost double our grid batteries - and when I say grid batteries that counts for every single battery installation at home too, because they are tracked when they are installed in the G98/G99 application).

    So you need to make our storage 300x larger just in Britain. And don’t say “we will just import electricity from other countries”, the dunkelflaute covered almost all of Europe.

    How did we get through that one? Gas, gas, gas, burning all across Europe, plus a lot of coal in Eastern Europe.

    Could we conceivably install 300x more storage in every country (bear in mind the situation is worse in most other countries, so adopting 300x across Europe is optimistic)?

    Yes sure, everything is conceivable. You could dig out every mountain for water storage and strip mine the whole planet for the metals you need for batteries.

    But if you add nuclear to the mix, prices fall dramatically, since nuclear adds baseload, meaning your dunkelflautes get much smaller and fewer. It’s a lot more conceivable with nuclear in the mix.

    Look, I’m not one of those “nuclear will fix everything” people. Nuclear has downsides, but so does everything else. The key is to mix upside and downsides, not rely on one single thing out of philosophy (whether renewable or nuclear).

    If you think “storage is solved” I urge you to speak to someone who works in grid management.




  • You’ve got some valid points in your criticism of nuclear. They are also points that could be addressed - we built lots of nuclear power plants within budget and timelines, once. Like solar, and like everything, nuclear benefits from scale.

    Similarly, there are valid points of criticism that solar gushing ignores: Power is needed 24/7, solar doesn’t deliver power 24/7 and batteries (pumped hydro, chemical, heat etc) are nowhere near large enough to see the whole of society powered through the winter. If we built renewables like we built traditional power plants we would say “I’d like 1 GW, 95% availability, steerable down to 0.6 GW”. Solar right now goes “weeell, not really my problem what you want - I can give you power sometimes and sometimes not”.

    So like coal power socialises the cost of pollution, renewables socialises the cost of consistency.

    We could instead say “storage is the solar field operators’ concern” and then you’d be able to see what solar really costs”.

    And hear me right; I’m ALL in on renewables. I’m also ALL in on nuclear. We need everything that can deliver power with low carbon output. If nuclear goes away, you’ll have to start a tonne of gas peaker plants when there’s not enough wind and not enough sun to power everything.

    It’s a mix, not a battle. Kill nuclear and you pretty much kill decarbonisation.







  • I really do think we could neuter social media’s harm by requiring them to positively identify users as actual people or own the consequences of what gets posted - like how a newspaper has the legal accountability for what it says. This “neutral platform” is not healthy for our democracy.

    I’m all for freedom of speech - but I don’t think those freedom of speech laws had anticipated how wide the damage of speech can flow and how stealthily things can be spoken. Is “freedom of speech” the same as “freedom to amplify anonymous voices to millions, with someone else choosing what voice to amplify”?

    And it’s not hard to set up. The EU’s new identity network requires zero-knowledge-proofs - ie “this is a real person” is all that social media platforms would be able to verify. I’d obviously be deeply against the social media companies being able to positively identify users.

    But I usually get downvoted to oblivion for making this point.
