it is the most efficient in terms of energy transfer. I think it is lacking in terms of actual storage capacity. the upfront costs are also extreme. ideally, every green energy far…

I'll have to check out the specifics - but your full setup does not seem like an improvement for me. If alexa is down, I can open up the app on my phone for each smart device manuf…

Apple and the garden of eden. Dont take a bite unless you're going all in

>they both work, I got an echo (alexa) for free and use it for home assistant. It only works when I have an internet connection. So when my internet is out, I cannot turn my lights…

so then we are free to allow any convention to take hold. so why not use the multiple different potential pluralities to differentiate between same species, different species, and …

government contracting and b2b services

On one hand I agree fully with this. On the other hand, if the government either is now or will eventually be owned by corporations then we might as well start setting a precedent …

What a great read. Saving this for additional research later. I also saw something related to harvesting some energy from the tides, which I think would fall under lifting or sinki…

Agreed on charge vs discharge comments. We seem to disagree on the storage numbers. Genuinely curious if my math is wrong on this. I did research a bit more about recent advancemen…

Completely agree with the hybrid approach wrt reducing emissions. I am talking more towards work that would be done concurrently with that. > During this build all storage technolo…

it's also why "storage" is a very loose term for gravity based energy storage. at a massive scale it is still only best at storing/discharging the difference between demand and sup…

good point, and yes its a small scrap yard. I was trying to emphasis that it's possible for a full-time commercial operation moving heavy metal to involve less weight than what was…

Awesome response. I've come across the molten salt option but havent researched in depth. I saw it referenced as something a lot of scientists are hyping up, but I am not sure what…

that is something people are doing. Also when you go down into rock, you are able to leverage pressure as energy storage as well - which is similar to what this article is about. T…

the 95% is misleading. it is barely storing or providing energy but it is a passthrough akin to plugging your phone into the charger 24/7 and saying your phone battery is providing…

95% stored energy by what measurement? See my other comment. It is not accessible to everyone, nor can it be made accessible to everyone, and the current storage capacity is a marg…

Makes sense, it is definitely a useful tool. I just think it is insufficient to act as storage. It can be good at producing variable amounts of Watts on demand but not so good at s…

emphasis on massive scale. Moving 500,000 kg (over 1 million pounds) 7.5 meters (~25 feet aka the height of a house) will give you about 10 kWh of energy. This is equivalent to run…

the AI giving you paid ads as part of normal conversation has a taste of dystopia to it, but I don't think it's creepy IFF the user is made aware of it beforehand. Definitely inclu…

The street is too dangerous, you are right. An experimental nuclear reactor, however, does not make the street safer. Additionally, the public is relatively unaware of how nuclear …
