> is going to be extremely high to make it profitable to build a plant that only runs 3% of the time.

It's probably fine, as the cost of renewable electricity is now lower than the fuel cost (aka the variable cost) of these plants.

In a lot of places, it's now cheaper to run a gas plant with renewables than without, as the build costs of the renewables is lower than the cost of the fuel they prevent to get burned.

"Au large" is an French expression and can be translated by "At sea" or "Off-shore".

Some smartphones or apps also do not record the full audio spectrum. iPhones works well, but Android support is not as good.

Hi author here,

This is a hobby project I've been working on for a few months. AMA !

Looks like the demands gets lower over the years, so my guess is that the stress on storage and hydrogen gets lower, and thus the price lower too

Your graph does not show the real return of the SP500, as it does not include dividends.

I don't own any electric car. What are the advantages and disadvantages of Tesla's standard vs CCS2 (pretty common in Europe as far as I know) ?

What are the advantages of this compared to cheap writable optical disks (DVD, Blueray ...)?

"Politicians in Europe know they will eventually have to impose taxes on electricity (or else raise income taxes)"

I heard that a lot, but are we sure about this?

Petrol in Europe is taxed at about 50%, but is almost exclusively imported, thus this is the only income for gouvernements.

Electricity, on the other side, is also taxed (about 25% here in Belgium). But's it's almost entirely produced in the Union, which creates additional income and thus taxes. In the end the government income generated by electricity production is most probably around 50% too.

Add to that the external costs of petrol cars that electric cars don't have (at least not as much), such as the huge impact of pollution on the healthcare sector, climate change, or the negative import balance caused by the import of fossil fuel... And it might well be that electric vehicles will be a better deal overall tax wise.

Is it 2% or 2 percentage points?

Like, if the attractive fund manager gets a 4% ROI, is the unattractive one getting 6% or 4.08% (0.08 is 2% of 4%).

Something similar happened when I put a dehumidifier in my bedroom.

Basically, I noticed that the room was heating significantly when I turned it on. Way faster than what you should expect from its power usage (about 250W avg.).

Correct me if I'm wrong, but by converting air moisture to liquid water using a compressor, the dehumidifier is releasing the latent energy of water vapor (0.627Wh/L) in addition to its own energy usage.

I measured that my dehumidifier required +/- 1kW/h to get 1L of liquid water from the room. This it's overall heating efficiency is about 1.6x, which is way better than any electric heating system that is not an heat-pump.

Do we have estimates of the energy requirements for these models?

I just did some napkin math, looks like inference on a 30B model with a GTX 4090 should get you about 30 tokens/sec [1], or 100k tokens/hour.

Considering such systems consume about 1 kW, that's about 10 kWh/1M tokens.

Based on the current cost of electricity, I don't think anyone could get below 2 ~ 4 $ per 1M token for a 30B model.

I had the same thoughts a few years ago.

The winner will not be the first one to the market, but the one at the right time with the best car on the market.

Actually quite the opposite. The EPR cost less per GW than what was announced for these.

No, but they do not provide the data in real time.

For Europe, there are academic and public organizations that publish these ENF backlog since about 2017.

For US, I couldn't find any open dataset. For these regions, I'm basically recording the sound of an A/C motor to get the reference data, but I only have a few months of backlog.

See here for the coverage of the webapp: https://datethis.app/coverage

Well, that's the very specific command I'm using in one of my webapps (https://datethis.app), and it's one of the main performance hotspots, so it's very *not* immaterial.

About 2x faster on my 4-cores ARM server, without any significant parallelism overhead:

    $ time ffmpeg_threading/ffmpeg -i input.mp4 -ar 1000 -vn -acodec flac -f flac -y /dev/null -hide_banner -loglevel quiet
    14.90s user 2.08s system 218% cpu 7.771 total
    
    $ time ffmpeg -i input.mp4 -ar 1000 -vn -acodec flac -f flac -y /dev/null -hide_banner -loglevel quiet 
    14.05s user 1.80s system 114% cpu 13.841 total

From what I understand, these TWhs refer to total energy usage, not electricity usage.

If you replace a ICE by an BEV powered by solar cells, you actually reduce the total TWhs because of efficiecy:

- ICE: 6L of gasoline per 100km, that equals to about 60 KWh

- BEV: 17KWh for the same distance.

The same applies to heat-pumps and some industrial processes.

It can still work somewhat great for parts of the economy.

E.g. healthcare, education, utility...

I'm working an a web app than tries to date audio and video recordings based on the network grid's noise.

https://datethis.app

I'm still working on improving the UX and the DSP. I made the DSP part open source.

What if there is no money to win, but only a huge risk for big loss of market share for FAMG companies if they don't get of the AI train?

Google Search might not earn more money it does now by buying Nvidia devices, but might loose big to a competitor if it does not.

My guess is that they do not.

Routing these packets around the planet would be a huge waste of their limited electrical and transmission resources.

I'm writing a open-source library (https://github.com/RaphaelJ/libhum/) and a webapp (https://datethis.app:8080/) that detects the Utility Grid noise emitted by electrical devices (A/C, motors, appliances ...) from Video/Audio recording.

It then tries to date the recording by matching it to historical data.

The signal processing part is getting decent. I'm still trying to collect more reference signals in RU, UK, China and Japan.

Tom Scott made a video about the idea: https://www.youtube.com/watch?v=e0elNU0iOMY

Thanks for the answer.

> Any small computer with AMD Phoenix offers a much better GPU performance per dollar than any NVIDIA Orin.

> The use of NVIDIA Orin is justified only when one needs a device that is qualified for an automotive environment.

Nvidia Orin will use significantly less energy though.

Any idea how the GPU compares to the Nvidia's Jetson series?

That's how TCP works.

TCP initially starts with a small transmission buffer (the congestion window), and gradually increases its size until it starts getting errors (packet drops or reordering).

I've been using Duckdns for a few months, I cannot recommend more!

Musk took over Tesla a few months after the Model S got announced. By that time, one could expect that most of the development teams and roadmaps were well in place.

I fail to understand how these could have been the results of vested interests from existing structures, and not Musk's questionable behavior:

- insulting a kid saving cave-diver a pedo;

- getting into a buying agreement with Twitter's shareholders, as a "joke";

- repeatedly asserting that FSD is a solved problem, and will be production ready in 6 months, for 6 years;

- repeatedly claiming to be free speech, but continuously enforcing politically backed censorship over Twitter;

- refusing to pay Twitter' suppliers.
