I believe they are all residential. There might be a few small businesses, but nothing huge.
- Comment on New community request - Amber Electric Users 4 weeks ago:
See my other comment reply for more context.
Amber is currently an Australian only electricity company, and the users are unusually involved compared to other energy retailers.
I think targeting wholesale pricing specifically instead of just Amber could be better. For the foreseeable future the two user groups would be identical, but a wholesale group would also encompass any emerging wholesale providers.
- Comment on New community request - Amber Electric Users 4 weeks ago:
The difference with Amber is the variable energy prices that can change every 5 minutes and vary between -100c/kWh and 2000c/kWh. Many users take advantage of these prices with custom battery automation, or want to know how Amber’s default automation (Smart-Shift) will behave in certain circumstances. There are very few options for whole home automation yet, so many users are developing their own, or asking for help using early access systems that are not yet user friendly. The automation and control of solar, home batteries, car charging, and deferable loads has led to a large amount of discussion that is centered around wholesale prices.
The group could be renamed to include all users of wholesale electricity prices. The suggested name is because Amber is currently the only electricity provider in Australia, so all discussion of wholesale prices and the effects of it has been in Amber groups. Because these groups are all non-searchable, the same questions have been asked many times by many people. A forum space like Lemmy would provide more resources to those just wanting a quick answer to a common question.

I find your lack of comma disturbing.

Prey gives you the choices up front, tells you they don’t matter, then gives you a really good game to play.
plot twist
The way you play is entirely up to you, but that’s the point. Are you who you say you are? It’s easy to say whether you’ll flip a switch or push a person when you’re answering questions at a desk, but it’s suddenly much harder when you’re actually faced with the problem. What will you choose?

If you are worried, a qualified medical practitioner is always more reliable than a web forum.
Insufficient or poor quality sleep can cause problems with attention and memory, and can exacerbate existing conditions.
Poor sleep could be caused by a medical condition (sleep apnoea), or psychological (stress). Often stress can be hard to identify, particularly if it’s long term stress.
Again, this might not be your problem, and finding the right doctor who actually listens to you is important. Don’t be afraid to try more than 1 doctor if the first makes you uncomfortable.

Can it be used for offline file transfer over LAN?
It looks to me like all transfers are over the internet.
- Comment on Had to burn off some excess oil from my chainmail hauberk. Thought it was cool 1 year ago:
The problem here is round trip efficiency.
Using a battery to store solar power is about 95% efficient. A small amount of energy is lost to heat when charging and discharging.
Using hydrogen as energy storage is about 30% efficient. A small amount of energy is lost when making the hydrogen, but a large amount is lost when converting it back to electricity.
Unfortunately this isn’t even a solvable problem. The fundamental limit of efficiency due hydrogen to electricity is about 50%. Physics and entropy prevent it from being any higher.
Burning hydrogen for heat is about 100% efficient, but heat pumps (running from electricity) can be over 600% efficient. Heat pumps get the extra efficiency by moving heat rather than creating heat directly.
If you wanted to use hydrogen from electrolysis, we would need 3 to 6 times as many solar panels than if we just used batteries.

As far as I’m aware, heating water with mirrors will just get you some really hot steam. I don’t think it’s feasible to split hydrogen from water using heat. Please let me know if I’m wrong.

Hydrogen made from methane, or from coal powered electrolysis?
- Comment on full tank 🚗 1 year ago:
Most electric cars have battery cooling, but the Nissan Leaf doesn’t. It works fine until you try rapid charging more than 2 times in one day.
I suspect that some high performance cars would also have motor and inverter cooling. This would likely not be needed for regular road cars as the motor and inverter don’t produce much heat.
