Yeah, looks like you are correct. It seems it was maybe as much about style/design as it was compression: https://solar.lowtechmagazine.com/2023/06/rebuilding-a-solar... https://solar.lowtechmagazi

I think the photos look like that to achieve a very small file size. The whole site is hosted and a small solar and battery powered server, so every MB matters.

Over-correcting from too much competence? Can’t tell if that’s what you meant (presumably sarcastically) or if you mean over-correcting from too much previous attention to DEI…

Ah, yes, that’s one of them! Not to be confused with AIFS and AIFS Ensemble that are competitive with IFS, but start with the same DA as IFS.

Yeah. I can’t remember names off the top of my head, but there are a few companies, and I think many researchers, working on AI “data assimilation” for this.

Pretty much all of the AI weather prediction models are trained on ECMWF ERA5, which is kinda like a numerical weather prediction model run to forecast at t=0. ERA5 is historical weather data, but it’s a “reanalysis” of it.

The required super wide field of view for the camera could be tricky, without making the box really deep. Or am I not thinking about it right?

I’m a few days late, but not sure why I got all the downvotes on this. Many regions/markets have relatively stable retail rate structures, i.e., residential and most commercial customers don’t pay day-to-day and hour-to-hour electricit

Capacity shortfalls and needs to conserve (i.e., asking customers to reduce usage) are not necessarily 1:1 with rate increases and overall electricity costs. Especially in the short term. In other words, large “base loads” like data centers

Great article! Paul Gipe’s website is also a great resource for anyone interested in the history of wind energy. https://wind-works.org/wind/history-of-wind-power/

True. But in terms of kids being able to explore computers, I think it’s a pretty good platform. What’s a better alternative?

> AWD doesn't help you stop in bad weather I frequently think about this when weather gets bad! I already have AWB (all wheel braking?). Seems like AWD could make it too easy to get in a situation where my AWB isn’t sufficient to st

EGS has been around for at least 15 years. See AltaRock Energy as an example (I’m sure there are others). They started almost 20 years ago. https://en.wikipedia.org/wiki/AltaRock_Energy

Maybe. But the original context here is an article about removing lead from gasoline. Which I’m pretty sure that helped many people based on the “greater good”. There’s no copper sulfate in canned green beans or borax in beef. Those seem al

> They constantly affect the poor more than the middle class. That’s a very broad statement. I expect there are many cases where that is not true.

None of the points you were responding to are “in theory”. You are proposing something that sounds like killing the US wind industry and then simply bringing it back later. That probably would work well, especially when projects have develo

That’s only because of the thermal storage. The output of the solar collectors is massively impacted by clouds, also just by haze and aerosols, much more than PV, which is happy with diffuse and direct sunlight. Then there’s the cost, which

Good point. It was all locally roasted beans at that point, so maybe that was what made the difference. Or at least contributed a lot.

I cut coffee for a year or so 10 years ago due to stomach issues, then slowly added fancy espresso drinks back, figuring that if I was only having coffee once a week, it might as well be fancy. I don’t seem to have stomach issues now with 1

The goal of using CRPS is to produce an ensemble that is a good probabilistic forecast without needing calibration/post processing. [edit: "without", not "with"]

Voc is just the open circuit voltage measured at the terminals (plugs). “Nameplate” Voc is at standard test conditions (STC) of 1000 W/m^2, 25 deg C cell temperature, and a standard are mass/spectrum. The combo of 1000 W/m^2

Hey! That’s exciting! Open-meteo is great.

Open-meteo does have ECMWF data and forecasts. Free for non-commercial use. I think the person behind open-meteo is on HN.

by sunshinesnacks 1y ago
Maybe I’m misunderstanding, but ECMWF provides a lot of data and forecasts for free [1]. And they are increasing the amount of data that is free [2]. [1] https://www.ecmwf.int/en/forecasts/datasets/open-data
