That's not really apples-to-apples comparison. The Tesla batteries are AC coupled so they work with an (AC coupled) microinverter array. For a DC coupled battery you have to have a hybrid inverter and DC couple the batteries.

Your point that they are overpriced still stands though.


Ya as someone else pointed out, powerwalls essentially have an inverter built in. But this is really dumb to have inverters tied directly to each powerwall battery. This is like anti-scale.

Well DRAM prices aren't going down soon so I see this as quite the push away from local inference.


Each core is multiples faster than a 90's CPU for various reasons as well. I think if you look at an entire rack it's easily a multiple of a 90's datacenter.


That's not a funny joke.


How many batteries is that? If we're talking solar and you have say a 300MW datacenter and you need it to operate for 12 hours without sun you need at least two of the largest battery install in the world[1] at 1700MWh. That doesn't factor cloudy days.

Another POV is, if datacenters are really constrained by power, by all means, offer users a discount when their queries utilize solar. Millions of Americans drive further to save cents to fill up their tanks - you can’t say there isn’t precedent among normal people to deal with this. The better question is, is it really a constraint?


Doesnt really work, as the biggest cost is buying GPUs etc which has to be paid for, and leaving them idle when the sun isnt shining doesnt pay the purchase costs. Their are industries where this does work though.


The customers time is not flexible like that.

And every second GPU is not working, it's not making money


> The customers time is not flexible like that.

A lot of the super expensive queries are flexible. Especially the agentic coding ones. And higher use naturally follows the sun anyway.

> And every second GPU is not working, it's not making money

Some companies already have more chips than they can feed, so if that continues then sure why not let it idle part of the night.


You both are talking about this stuff as if it is a new concept. Demand-based pricing is already commonplace for both electricity and compute.

The demand for both compute and electricity is higher while people are awake and using them. But not all demand is realtime, and some will shift in response to prices.


> The customers time is not flexible like that.

haha how do you figure? with how much time people spend playing league of legends, watching tiktok and standing in line for "Free" shit, i think their time is actually quite flexible


Don't forget fury x!


Yes, did you read it? Hydrogen and solid carbon, so the result is no greenhouse gas emissions.


Wrong. First of all only 25% of the natural gas inserted into the reactor are converted (with the rest presumably resulting in emissions) and natural gas also produces emissions during exploration and exploitation


That doesn't quite match what the wikipedia page says:

> The official abbreviation for Coordinated Universal Time is UTC. This abbreviation comes as a result of the International Telecommunication Union and the International Astronomical Union wanting to use the same abbreviation in all languages. The compromise that emerged was UTC, which conforms to the pattern for the abbreviations of the variants of Universal Time (UT0, UT1, UT2, UT1R, etc.).


Follow the citation: https://www.nist.gov/pml/time-and-frequency-division/how-utc...

> ... in English the abbreviation for coordinated universal time would be CUT, while in French the abbreviation for "temps universel coordonné" would be TUC. To avoid appearing to favor any particular language, the abbreviation UTC was selected.


Fun fact, early hand written lyrics were "purple haze, Jesus saves...". It was a recollection of a dream where he was walking under water. The connection to acid is more so by interpretation of the audience.


It's not more associated to cannabis? There's many strains even named for it.


This presumably happened later, as LSD became less popular in the underground drug culture.


Less accessible. Illicit LSD production will probably never be as widespread as it was before the List of Chemicals was introduced. You can develop alternative manufacturing methods for most drugs. But a hexahydroindolo[4,3-fg]quinoline? Not so easy.


> LSD became less popular in the underground drug culture.

Hmmmm...

Maybe relatively less popular, as the menu of recreational drugs is expanded from a very few bad ones to a cornucopia of good ones, but still very popular


LSD definitely had a resurgence and it's very popular again today, but it's still accurate to say it lost popularity the crackdowns at the end of the 60s.


Problem was in the 90s most North American supply was apparently coming from a couple of guys and when they got busted it almost disappeared overnight.


Yeah there was the mini resurgence in the late 80s, early 90s but I think the scene since the start of the 2010s has grown to be bigger than ever in a certain sense.


Nowadays I only ever hear people talk about it in the context of former users, or general discussion of the 70s.


Huh? Demand is local. Where I live there's a lot of demand because it's a desirable city and leaders talk about this demand consistently.
