- Comment on Framework laptops get modular makeover with RISC-V main board 2 days 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 1 week 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 1 week 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 1 week 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 weeks 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 weeks 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 weeks 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 weeks 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 weeks 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 weeks 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 5 weeks 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 5 weeks 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 5 weeks 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 5 weeks ago:
Sadly no info whatsoever on batteries.
- Comment on Sweden switches on largest battery energy storage system in the Nordics - Energy Storage 5 weeks 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 1 month ago:
Sure, but then again, there are other elements as well.
- Comment on Altech’s sodium chloride solid state battery exceeds expectations 1 month 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 1 month 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 1 month 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 1 month 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 1 month ago:
Awesome, I win! But seriously, I do hope we pull something off ASAP, being hydrogen or some sort of battery or whatever.
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
Let’s continue the conversation after a couple of years?
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
I guess we are stating the same, just from different perspectives. About Germany, you are correct that it isn’t just their push towards renewables, it was a combination of ditching nuclear power and going full renewables. The real world outcome was huge pollution. That was indeed reduced by renewables (each year more) but still, it was enormous and it’s still pretty huge and will be for a foreseeable future unless they come with enough surplus of renewables and huge energy storage. I don’t see the later coming soon, though. The France does it right, they rely on nuclear.
You say (correct me if I’m wrong) that renewables (even without storage) are reducing emissions because they reduce fossil fuels usage, and you are definitely right. I’m saying that that’s not enough, we have to ditch fossil fuels entirely and if/when that occurs, renewables without storage are not that useful since we will have to rely on stable non-co2-emission power source - which is only nuclear today.
Sorry to go so hard on this Hey, it’s a healthy debate.
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
You think? I’m saying that we can have a strategy, but that doesn’t guarantee the outcome. Again, show me a city scale energy storage today. So, until we have one, it’s vaporware. Basically this strategy is based on what exactly? Hope?
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
Strategy doesn’t mean it will be actually implemented or it’s the best. For example, Ursula instructed the transportation guy to try to implement Hyperloop. Shall I say more? :) There is also strategy to ditch fossil fuel cars soon…
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
Germany enters the chat…
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
Sure, I agree that it helps, but only as long as you are emitting co2 as an alternative. Not sure whether comparison to USA is a good one since they ditched new nuclear plants after Three Mile Island accident. Try comparing against France though - they are the greenest and most reliable energy producer out there (maybe Scandinavian countries are better, but they have excellent predispositions). And then we have Germany, which went diehard renewable with the side effect of becoming one of the biggest European polluter.
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
Could be, however hydrogen is really tough to handle plus green generation is around 50% efficiency (something like that). Also imagine having huge hydrogen volume and there is a spark…
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
I can guarantee you that there are conditions when sun and wind aren’t producing a thing or very low output, like during night you are at mercy of wind (hydro is another story, is more stable but even there we experience droughts). So, what do you do when all three (night, no wind and drought) hits you like for a week?
- Comment on Tripling renewables globally by 2030 is doable, says new IEA report 1 month ago:
Are they, though? Can you list some bigger storage facilities based on either H or batteries? Like ones that would power a city for few days, for example.
