Overzeetop

I've run into people on Lemmy who have created a community for themselves to produce an endless stream of articles that are posted in from the various tech trade rags. I took the high road and blocked the community rather than suggesting that the community moderator learn how to use RSS.

Easily the most depressing statistic I've read this week.

It's a shame she's not a male athlete with a promising swimming career. Might have gotten off with having to take a remedial driving course and paid a small fine.

If you're not writing your own software for the phone, and you don't need access to the raw sensor data, there's likely an equal app for iPhone now. I was in the same boat for a while - needing things that only android offered. I switched to iPhone in '19 I think, and I've found replacement apps for everything except detailed wifi scanning. Also, the apps I used on android which offered direct GPS tracking would show how many satellites and nominal locations are just binary - you have signal or you don't. That's frustrating when you're at the edge of signal and trying to get a lock.

I can see how it would be a deal breaker if you need a specific app for work. I can't switch to mac as several of my (multi-thousand dollar) analysis programs are windows only, and if an update breaks something or there's an incompatibility, it costs me $2k/day to troubleshoot.

Entirely true, but since we're talking volume, this is only a 25% increase in linear dimensions (for the advertised 2x increase) or 35% (for the 2.5X maximum slurry density). If we are limited to a specific height of retention, that's 40% and 60% (rounded). Note: for structural capacity, like a tank, retaining a g=2.5 liquid requires substantially higher strength than a g=1 liquid (for a given retention height). Since this is the internet and should source my knowledge: I know this because I happen to be an engineer who designs retaining structures. Anyway...

For the effective cost of creating and maintaining the slurry, maintaining the integrity of the system (and keeping out wildlife), and the cost of decommissioning the otherwise unusable fluid, you're likely talking about a reduction in area of 20-38% (1/8) to switch from using plain water to this engineered material. I don't disagree that there may be some edge cases where the increased risk and expense is justifiable, but it's hard to see this being viable except as some kind of tech demo.

This is logically efficient from a technical standpoint, but from a practical perspective is a terrible idea. You're only getting 2-2.5x th energy storage out of the process, but in return you're effectively requiring that the entire fluid system be isolated from the environment. Toxicity aside, you can't do anything with the fluid outside of the system. It's probably not something you want local fauna drinking, nor do you want even the slightest chance of this leaking into the local aquifers. I presume that, if it's not fully isolated, the fluid mix balance would have to be adjusted to offset evaporation of the water. And if the plant turns out not to be as great at you hoped hat do you do with the fluid?

Some numbers - a quick google says "According to Ofgem, the typical household in Britain uses approximately 2,900 kWh of electricity annually." I'm going to round that up to 8kWh/day. For a small village of, say, 1250 homes and a three day storage capacity, that's 30MWh. 1MJ (MWs) is 1000kg (one metric ton) stored at 100m - the upper end of this project. Since 3600 seconds per hour x 1MWs = 1 MWh, and we want 30, that's 1MT x 3600 x 30 = 108,000 Metric Tons of this high density liquid needed for a small project to put a 3 power day buffer in place for a town of 1250 houses. WTF are you going to do with 108,000 metric tons of high-density fluid if you decide is isn't working? Your reservoir would only need to be 25% bigger (wider, longer, and deeper/taller) to just do the whole thing with water and you wouldn't need to figure out how to get 3500 full size tanker trucks to transport it all away somewhere for a different project for for de-slurry processing.

Seriously, how can you possibly look at his history of dealings and not know, going in, he's going to screw you over / toss you under the bus the moment things get dicey.

First rule of finding yourself in a hole: Stop Digging.

Wow - this quote is about as close to having no regrets as you can get and still saying you'd choose differently.

Do I regret it?’ Well, I would probably put it this way. If I knew what I know now, which included all of the opportunity, energy it would take away from the core business I would have not entered [the agreement]

She basically said the money she was paid didn't improve her bottom line enough for the work involved. That's pretty darned far from "regret".

We should make them call it Bovine Mammary Secretion.
