Agreed — that’s the core issue. Aluminum-air doesn’t fit the mental model people have of a “battery” since it isn’t rechargeable in the conventional sense. Once you require anode replacement or external recycling, it stops competing with AA or Li-ion on convenience.

From what I’ve read, the hybrid demos weren’t true recharging but more of a fuel-cycle approach using aluminum as a consumable. That makes it fundamentally different.

That said, I’m not sure it needs to replace AA or Li-ion to be useful. Do you think there’s still room for technologies like this in niche or emergency scenarios where shelf life and energy density matter more than rechargeability?

So at what age do you think one should realize this?> Your over 30 and you just realised words have different effects on people?

30+ here. Drink more water, wear sunscreen, take photos of your friends, and don’t marry someone just because the Wi-Fi is shared

Fusion power will probably go the boring “heat → turbine” route for giant power plants.

Ironically, the things that are most useful in real life tend to be much simpler — basic chemistry, easy to use, and they don’t care if the grid is down.

Me too, came from reddit.

I don’t really care whether LLMs are “intelligent” or not. In the real world, tools either work or they don’t. Same as a generator, radio, or water filter. They can extend your capabilities, but they never replace judgment, planning, or responsibility. Over-reliance is the real risk.

Same here. I’m still on Reddit, but the moderation can feel unpredictable, and it’s discouraging when normal comments get flagged. Finding Lemmy has been refreshing, and I’d like to see the community grow into something sustainable and balanced.

My “silly little website” isn’t really that silly — it’s about exploring clean, alternative power like aluminum–air and saltwater systems. I’m genuinely interested in how such chemistry-based power could support resilience in remote or disaster-prone areas. That’s what I’ve been building at www.wehometool.com .
