It would be for the completed battery units with BMS. You would have to install the batteries into the battery cases. It is a bit tedious but it was otherwise straightforward. The batteries are extremely heavy.

I have always had good experiences with signature solar. My inverters are EG4 and I am very happy with their product after trying A LOT of others. I think the primary reasons for the price difference is that you are purchasing US inventory (it's already here), it's preassembled and warrantied as a unit, they provide pretty decent support and their battery packs use 100ah cells instead of 280ah+ cells. So you are buying ~3x as many BMSs, connecting cable ($$$$) and cases for the same power.

Their rackable units are not light but can be moved by a capable person without too much fuss. A fully loaded 280ah unit in it's case is over 250lb so you really need a lift cart or such. The 280ah units and now maybe 320ah are more economical.

I can see why 8-10 years looks like a wall in terms of how much total solar we want.

However panels age which costs ~1% of capacity per year even before they need to be replaced, and global electricity demand tends to increase 2+%/year. So the more solar you install the more you need to install every year just to keep providing the same percentage of total electricity.

On top of this lower prices mean you it's still worthwhile even if a larger percentage of output gets wasted. Similarly, as storage gets cheaper (inflation adjusted) there's going to be more demand to cheaply charge it thus raising the demand for panels.

And while the site is badly designed, it does not have to explain why you should "trust these people". They should tell you what the product is, and for you to decide whether you like this product enough to buy it. Unless you suspect they'll run with your money (this isn't a kickstarter) or that the product claims are untruthful, trust is irrelevant.

The reason companies in this space fail is just because too few people have been interested in this class of product. Maybe one day, when smartphones are more powerful and these products are convenient enough.

Instant pots, kettles, dishwashers, microwaves and toasters all reduce energy consumption to do the same thing, but I don’t think anyone bought them for those reasons.

The most effective method to reduce/shift consumption is just to make it the easier way.

Adding cognitive load to shopping decisions and their daily lives is predictably ineffective for the general public (and almost universally hated).

That majority will be a bit poorer because of it, and many will cheer that aspect but it also means the target goal has failed.

>Manipulating actual flight controls is probably hard.

Why? The flight sticks have an ADC, just control current/resistance there to get the desired digital values. Of course assuming fly by wire an symmetrical input on both sticks.

Probably far easier than manipulating the digital data downstream, which is subject to lots of checks.

If the application fits, choosing one of the BSDs with the more popular chip families can work well. In other words, if the BSD crowd likes an SoC, you'll get a good, stable system running with good kernel support. In my case it's the RockChip family, specifically from PINE64.

Examples:

- PINE64 Rock64 running FreeBSD 14.1 replaced an aging RPi3. I use this for SDR applications. It's a small, low power device with PoE that I can deploy close to my outdoor antennas (e.g. 1090mhz for dump1090-fa ADS-B). It's been really solid with its eMMC, and FreeBSD has good USB support for RTL-SDR devices.

- PINE64 RockPro64 running NetBSD 10. I have a PCIe card with a 500gb SSD M.2 slot. NetBSD has ZFS support and it has been stable. This lets me take snapshots on the SSD zpool. I generate time-lapse videos using the faster cores.

You don't get 100% HW support (e.g. no camera support for RockPro64) but I don't need it. The compromise is worth it in my case because I get a stable and consistent system that I'm familiar with: BSD.
The panel strings are at ~500v so there are safety, fusing and grounding considerations. Pretty common electrical equipment and cable is rated for use at 600v. There are special locking water resistant connectors for solar panels called MC4.
Agreed that the website is mid but I don't get the part where you say:

I'm completely confused here, sorry. Are you talking about this submission? People submitting their own work with their first post is totally fine, especially if they're around to talk about it. These are some of the best threads HN has to offer, often. The guideline is about not using HN to post your own stuff exclusively but it's, you know, a guideline rather than a mathematical constraint so the trivial case of posting your own stuff on HN for the first time is not merely fine, it's a good thing.

Edit: Maybe I'm figuring it out, is it that you thought that self-posting is strongly discouraged and that 'Show HN' is a label you're supposed to use to identify self-posting? They're not directly related, Show HN is just a special HN category with its own subsection and its own extra rules. Nobody has to use it but if you do use it, the post has to be within those rules. The other, somewhat orthogonal thing is that you can post your own stuff (in or outside Show HN), just don't overdo it.
I wouldn't call it "illegal", but international trade agreements define situations in which it is permissible to counter subsidies with retaliatory tariffs.

The EU has retaliated against the US's subsidies for Boeing before, although those tariffs are currently suspended.

Tariffs to counter chip subsidies would likely be permissible as well.

You’re right, IndexBlaze does leverage Google’s Indexing API to speed up the indexing process. While the API’s official use case is for job postings and short-lived pages, it can effectively get any page indexed, which many SEOs have discovered.

I understand the concern about potential future changes in Google’s algorithms. However, as it stands, using the Indexing API doesn’t incur any penalties and remains a valid method.

I agree not the same downward curve, but it also has been on the downward curve, although different. Learning rate is rather a common phenomenon.

Estimating the learning curve of solar PV balance–of–system (2018) estimates 11% learning rate for BOS compared to 20% learning rate for module.

This is a controversial hypothesis that is merely from a idiot, being myself. I don't truly believe this but it something I have throught about.

Energy costs are THE driving force of prices. The cost of materials is essentially the energy it takes to squire/process/ship them. If energy was free, we would just dig up random patches of dirt and sift it for every material we wanted even in trace amounts. But its not because unfortunately, we are still primarily a fossil fuel economy for many reasons (legacy, price, chemical properties) and their cheap price relative to labour is acting as a subsidie to renewables pricing. So if the availability of fossil fuels deminishes it seemed logical that the price of inputs goes up and so too would renewable manufacturing. We would then see an inverted bell shaped curve on pricing over time. I have long suspected we would see this trend of lowering prices revert around the 2020s. So far I have been pleasantly wrong.

But fossil fuels like almost all minerals is fighting an uphill battle on availability and ore quality as we used the best stuff first. The US isnt fracking at the pace it is because they just wanted a laugh. It is due to the primary "conventional" stuff couldnt keep up. But that is a whole different issue.

If renewables were offsetting fossil fuel usage, this wouldnt be a problem but it is merely being added on top of it. Thus Jevons paradox in full swing. If we can over come that then this whole idea can be thrown in the recyling bin.

When we can make a solar panel with the outputs of a solar panel, then that is the escape velocity moment. And I don't just mean counting the joules and ignoring the energy fungability.

I am much more optimistic about this in the last few years but im not sure we are there yet. It is looking reasonable now.

How big a battery can you make when it’s made from sand?

The trick with grid is that because you’re building at scale, you can give the benefits to many in one shot and you can build it out of town. Think Australia’s original big battery from Tesla in 90 days vs. messing with installing lots of little ones in houses, with all the maintenance, education and dangers that brings.

I've never really felt like Kafka seems to have and I read a lot, mostly novels. For what it's worth, I don't love Kafka's novels: I think he wanted them burned for a reason -- they're meandering failures. Very clever but they don't go anywhere. His short stories, though, are excellent.

Gulf war against 90s Iraq with 20m people and ~800 1960s missiles (scud Bs) required 5 carrier groups + regional air basing for air campaign, completely compromised Anti Air (by french who designed Iraq IADS and gave schematics to US). Relative to modern Iran with 80m people and 4x more missiles with 2000s rocketry tech, much more favourable geography (facing water), 1990s Iraq/Gulf War would not even measure up as a medium power / major war. One (1) carrier with 150/270 (short term surge) sorties per day is not remotely enough against a medium power. Can US surge 6-7 carriers + forward deploy air force with advanced notice to tackle Iran, yeah, but it wouldn't leave much left for anything else. CVN69 isn't exactly defeating the houthis right now. That's the numbers behind why US doctorine downgraded to 1 major war + 1 holding war (with medium/small adverary), while near/peer war with PRC is currently a toss up.

For a local databus it has been relatively unimportant. However, there are radio data links in/out of the aircraft. The scope of data for these links is quite limited today, but likely to grow significantly in the future. There cryptographic properties become important, and a currently missing. An example would be ACARS.

Also in some aircraft types these data buses are unfortunately not so very hard to access (i.e. accessible from the cabin, with undetected access being even plausible in some cases). So some resilience might not hurt in these cases.

It's important that failure of critical systems is far less threatening than systems providing plausible, yet incorrect data. Redundancy and monitoring catches most of the former but not the latter.

The real barrier for recycling waste is sustainability. This is the reason why e.g. TETRABRIK is considered recyclable, but it is actually not (I am posting about this parallel because it has been completely understood for several years)

Anything can be recycled if we are pedantic. But will it actually stop generating waste? (or will they be silently exported ignored?) Will subsidies be sustainable? (not it even asking if it can be profitable) In reality, the "recyclable" brand is for the most part greenwashing.

Now, the business ad about a venture capital bussiness you posted is nothing new. Last year there were 5 such touted recycling plants in Latin America, already. One of them is located in Costa Rica. Costa Rica doesn't have a Lithium battery waste issue. There, the electric cars are very few (and people who got them already want out), there are no electricity storage facilities. I am guessing here that they will import a ton (hundreds of tons) of waste from "Somewhere else"

I am including an article on battery recycling that is easy to read. It is only 40 pages long.

https://archive.ph/wip/XB8hw

And, for more downvotes: Lithium batteries are as recyclable as a TETRAPAK: still generating waste, most of the time all of it ends up as waste.

The papers referenced in the BLIS repo are the authoritative reference to understand this stuff. I've no idea why people think optimized BLASes aren't performant; you should expect >90% of CPU peak for sufficiently large matrices, and serial OpenBLAS was generally on a par with MKL last I saw. (BLAS implements GEMM, not matmul, as the basic linear algebra building block.) I don't understand using numpy rather than the usual benchmark frameworks, and on Zen surely you should compare with AMD's BLAS (based on BLIS). BLIS had a better parallelization story than OpenBLAS last I knew. AMD BLIS also has the implementation switch for "small" dimensions, and I don't know if current OpenBLAS does.

SIMD intrinsics aren't needed for micro-kernel vectorization, as a decent C compiler will fully vectorize and unroll it. BLIS' pure C micro-kernel gets >80% of the performance of the hand-optimized implementation on Haswell with appropriate block sizes. The difference is likely to be due to prefecth, but I don't properly understand it.

I came across this interesting 'bingo sheet' style website for tonights UK General Election and wanted to share it, results will be coming in throughout the night and I'm somewhat unsure whether they're hitting an API to update this, or just working tirelessly.

> Well, the price of lithium dropped 80% in the last year.[2] Overproduction at the moment.

...

> This also means that sodium batteries will probably be unnecessary.

If we're overproducing this doesn't follow. Lithium prices will rise back to the price of production. I'm not an expert but quickly glancing at the futures market and it looks to me like there is only a small rebound predicted ($13.30 -> $17.00/contract over a few years, highly illiquid market so take prices with a grain of salt) so the actual story might be "lithium production has become much cheaper".

It also doesn't really matter if you're trying to estimate "it will cost at most this" by looking at sodium ion batteries. I don't think the author really cares if the batteries are sodium or lithium based, just that they don't cost more than sodium based batteries would cost.

> This is good, because of the fire risk

One of the selling points for Sodium ion has pretty consistently been that they are non-flammable. Admittedly this is a function of the electrolyte they use and not a fundamental property of sodium vs lithium, so it might change in the future, but I don't believe it has/it is in anticipated to?
