- Comment on US bans controversial red food dye, decades after scientists raised alarm 2 weeks ago:
It’ll take at least until 2028 apparently. That’s really late.
- Comment on Polish president says don't arrest Netanyahu at Auschwitz ceremony 3 weeks ago:
Hey, perhaps they merely want to show a genocidal leader in person.
- Comment on Renewables supply 71% of Portugal’s electricity in 2024, led by solar 3 weeks ago:
Hydro is more or less constant and wind is random. How does one cover a huge amount of solar energy when it’s out? You can’t increase hydro and you can’t force wind to blow.
- Comment on Renewables supply 71% of Portugal’s electricity in 2024, led by solar 3 weeks ago:
Well, I doubt it a bit how much pumped hydro capacity is there in Portugal, but you’d need an obscene capacity if you wanted to go full renewable partially based on solar panels. Found this by quick search:
"However, the dependency on electricity imports from Spain will increase significantly, especially in drier years. " www.sciencedirect.com/…/S2352152X24037800
Basically you’d be using Spain as energy source when you don’t have enough energy at hand.
- Comment on Renewables supply 71% of Portugal’s electricity in 2024, led by solar 3 weeks ago:
Other things run through night such as heat pumps, water heaters, EV charging etc. And those other sources are usual fossil fuel based which emit a lot of pollution and CO2. And it doesn’t work that well in other countries when you reach a threshold.
- Comment on Renewables supply 71% of Portugal’s electricity in 2024, led by solar 3 weeks ago:
There are those things called nights, clouds and shorter winter days 🤷♂️
- Comment on Renewables supply 71% of Portugal’s electricity in 2024, led by solar 3 weeks ago:
Where is even coming from when there is no sun?
- Comment on Renewables supply 71% of Portugal’s electricity in 2024, led by solar 4 weeks ago:
Not so high without an adequate storage.
- Comment on Trump says Zelensky is ready for 'deal' with Russia 1 month ago:
I’m looking forward to January, 17th to wake up with news that 3 days special op ended. /s
- Comment on Framework laptops get modular makeover with RISC-V main board 2 months ago:
Fingers crossed for RISC-V to evolve quickly to at least a decent alternative to current laptop/desktop CPUs.
- Comment on 'UK-first' intercity battery trial train outperforms diesel 2 months ago:
Yes, sure, like every technology out there. But the maintenance is cheap compared to initial investment. I guess one can compare it to batteries having limited cycles, faults and even catch fire.
- Comment on YouTube Premium’s legacy price breaks are going away for more users 2 months ago:
And still no just YouTube subscription (without music) and no family plan for Slovenia.
- Comment on 'UK-first' intercity battery trial train outperforms diesel 2 months ago:
But still, wouldn’t wires over the train make more sense - no distance limits, no charge time, lighter train, no batteries required and perhaps better efficiency. Infrastructure would be one time investment. 🤷♂️
- Comment on Lithium-ion batteries have ruled for decades. Now they have a challenger. | Sodium-ion batteries are emerging as a possible alternative. 2 months ago:
I find it hard to believe that they kept 100% charge for years even if perfectly designed. 🤷♂️
- Comment on Lithium-ion batteries have ruled for decades. Now they have a challenger. | Sodium-ion batteries are emerging as a possible alternative. 2 months ago:
Yes, please, they are very welcome for large energy storages. And as article states, not for anything that requires energy density (mobile devices, EVs and such).
- Comment on In 4 years, US power grid increased battery storage to the equivalent of 20 nuclear reactors | The Optimist Daily 2 months ago:
How can an article reliable convey information when the core measurement unit used in article is invalid? Not taking about slightly wrong numbers, but the foundation of the article.
- Comment on In 4 years, US power grid increased battery storage to the equivalent of 20 nuclear reactors | The Optimist Daily 2 months ago:
No worries, no need to remove it, it’s just articles that doesn’t make sense.
- Comment on In 4 years, US power grid increased battery storage to the equivalent of 20 nuclear reactors | The Optimist Daily 2 months ago:
Can we please not post such dumb articles? Like any article mentioning battery capacity in watts
- Comment on Solar module manufacturing capacity could exceed 1.5 TW by 2035, says IEA 2 months ago:
Obviously now we should invest in energy storage, otherwise solar modules go just so far.
- Comment on Nevada is getting the world’s first lithium-sulfur battery gigafactory 3 months ago:
Uh, they are less stable that li-ion, like fires? Ouch.
- Comment on Sweden switches on largest battery energy storage system in the Nordics - Energy Storage 3 months ago:
Ha, right. Seems that distinguishing between power and energy is really a hard task (for journalists).
- Comment on Sweden switches on largest battery energy storage system in the Nordics - Energy Storage 3 months ago:
Yeah, I was hoping for other less toxic and more nature friendly ones, too.
- Comment on Sweden switches on largest battery energy storage system in the Nordics - Energy Storage 3 months ago:
Sadly no info whatsoever on batteries.
- Comment on Sweden switches on largest battery energy storage system in the Nordics - Energy Storage 3 months ago:
It literally says in first paragraph “…in Sweden to deploy 211 MW / 211 MWh…”
- Comment on Altech’s sodium chloride solid state battery exceeds expectations 3 months ago:
Sure, but then again, there are other elements as well.
- Comment on Altech’s sodium chloride solid state battery exceeds expectations 3 months ago:
Indeed awesome. Sadly no words about recycling such a battery, though it sounds like it should be fairly recyclable.
- Comment on Paralyzed Man Unable to Walk After Maker of His Powered Exoskeleton Tells Him It's Now Obsolete 3 months ago:
Cars are probably covered differently by law, like minimum years producer has to offer replacement parts and such. Probably all boils down to the contract for that exoskeleton. Definitely not an excuse for that petty company trying to suck tens of thousands of dollars instead of a simple repair.
- Comment on Biodegradable wind turbine blades, a promising improvement for lowering waste with wind energy | Just Have a Think 3 months ago:
Exactly what we probably said for plastics. And here we are now. The logic of, it’s just a “small” amount, why bother is so wrong. What good is to piling trash?
- Comment on Mahle CEO Arnd Franz says hydrogen will fail without fossil fuels 4 months ago:
But theoretically the storage can scale well and it’s relatively cheap, albeit who really knows about the price for storage since there are no at scale storages out there yet.
it’s only zero emission if you use a fuel cell
What do you mean by this? However you burn it, it’s zero emission, isn’t it?
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 4 months ago:
Awesome, I win! But seriously, I do hope we pull something off ASAP, being hydrogen or some sort of battery or whatever.
