Thank you. The moment these have reasonable pricing I'm ordering up enough to put together a 200 KWh home battery. It isn't quite economical yet but there is no way I'm putting such a quantity of Lithium-Ion in anything near

How many / what size do you have?

What is your take on Lithium-Titanate (sp?) cells?

Sytse is one of a kind, not a doubt about it.

I've already done this. It's a thing one person can do in under a year.

BB is a very traditional company, they're very much stuck in the 90's when it comes to software licensing. There is a BB QnX team member here on HN they can probably shine much more light on this than I can (but I realize they may

Selling it back to the grid is something that is still possible but much, much less of a financially sound proposition than it was a few years ago because of regulatory capture by the utilities. In some places it is so bad that you get pena

I spent a ton of time on trying to do just that years ago and it went nowhere, calibrate your hopes accordingly.

You brought back a memory, a second hand one, but still a great story. A guy I knew long ago had emigrated from NZ to NL. His main claim to fame in NZ was that one day he showed up drunk for work. In itself this wouldn't have been memo

Yes, I see the flipside just fine, but we should all keep that flipside in mind all the time and not to let these tools get under our skin. That's why I keep any AI interaction off my main computer: no risk of contaminating my profes

Mythbusters time. Salty fluids can be remarkably conductive. Blood qualifies. What's interesting though is that you have to wonder if there isn't some contributing factor here, as a kid I did this quite a few times, so that's

Indeed. And it's a really nasty thing to properly protect against because that pollution, especially with stuff that is unattended for a long time has a habit of ending up much worse than your worst fantasies. I've taken more than

If you have an emotional response to anything an agent or LLM does then you should lay off the sauce for a while and take a walk or something. This stuff is just dumb tech, no matter what the appearances and it does not warrant you getting

Not quite that scale, but this one is very impressive as well. https://en.wikipedia.org/wiki/Grand_Coulee I drove out to see it when I lived in Canada, it is very hard to describe the incredible feeling of tinyness you

A close family member did just that. They absolutely love history and are super well informed about lots of interesting subjects. The downside is it basically sets you up for becoming a history teacher and that's not the most rewarding

Of course you can. That's kind of obvious. It is also highly impractical. Besides the frequency delta you end up having to lug a heavy transformer along and then you have to alternate it across your tools so you don't end up fryin

You can use nvidia-smi to reduce the powerdraw of the card to just below what will trip the breaker.

I'm the idiot that sent a fairly high voltage spike into the grid setting off a cascade. Even years later I do not fully understand how it could happen, you'd think the grid would be low impedance enough to absorb a spike like tha

Holy crap. That's a whole series of bad ideas extremely well executed. That guy probably has never seen what a lead acid battery can do when it explodes. He keeps hiding away from the hot metal but in the path of ~half of those batteri

Not so simple, you'd have to use a 'drier' or 'welder' socket for that otherwise you won't have enough power. A single circuit in Europe is 240V 16A or 3840W! A pure sinewave inverter for that kind of power is

This would be the funniest thing to do. 100K Amps is doable, the question is for how long. That would be one very impressive bank of capacitors. And to turn a 00 into plasma would have some spectacular side effects, such as raining molten c

Well, as you say, it would not be according to code and the insurance company might have something to say about it. It's also single phase but not quite the way you do it in the USA, it would be a neutral and a phase whereas in the USA

I have a couple of those narrow escapes one of which led me to put a significant chunk of Eastern Amsterdam out of power. Another involved Beryllium oxide. 9 lives are barely enough.

It's almost worth the experiment and your cables are a sacrifice I'm willing to make. For science, of course.
