Here's a smaller scale water battery that heats an entire house year round. The water tank itself is placed in the center of the house across all 3 floors and actually makes for a quite nice design element as well. The energy is generated in the warm seasons and the volume of water is large enough to last through the entire winter. It's a German vid but subtitles are quite accurate.

Doesn't this suffer the problem that you're then putting heat into the device, which is in your house, during the warm season when you want your house to stay cool?

Think of the water tank as being in but insulated from the house.

In the hot summer the hot air within the house is cooled by heat pumping the heat into the water tank which is slowly over weeks bought up from cold to mean summer tempreture.

In the winter the heat is extracted from the water and transfered to the house.

The house and the water mass are out of phase by six months.

It's a large enough volume of water, that adding insulation is feasible.

But then why put it in the house and not e.g. in the ground?

1. Not possible everywhere 2. Probably more expensive

You don't even need water, you can just transfer the heat to the soil under your house

Gave this a go. Just so happened that I had the page of an eBay seller open. Wondered if it could manage to do something as simple as extracting all 240 listed products on that page. Instead of determining that the most important data on this page would be the products, it identified these properties: categoryName, subCategories, link.

yeah i tried with a type of website that i commonly write scrapers for and i'm not sure if i can do anything with these results.

ai + web scraping is hard, i've tried and gave up, but that doesn't mean it's impossible, it just means i'm not a good engineer, so i will stay tuned to kadoa project.

Absolutely not knocking this project. Was just a somewhat unexpected result from such a simple site. Asked GPT-4 to write a scraper just to compare and it produced a quite usable boilerplate.

I'll look into this, we have a specific workflow template for ecommerce as it's always a similar data schema.

Impossible to even create an account from within Germany as a consumer. This is what their registration form says: (Only for business people and companies - section 14 of the German Civil Code - with location in Germany - not for consumers)

Fundamentally, yes. A tube shaped anchor with a designated/predetermined crumple zone. They're widely used in sheet metal fabrication, where thin walls wouldn't allow for sufficient thread engagement. Where spot welded nuts aren't possible, for instance in a long, thin walled tube etc..

For composites, if the back side is accessible, a standard rivet nut + tightly fitting washer on the back side works quite well to alleviate the risk of stress fractures.

Quite a lot of windshield wipers have metal inserts with the same properties & dimensions. Perfect to open your older car when you forgot the keys inside.

Interesting side note: Self proclaimed gurus and scammers of every possible kind love cameo's services, too. Makes the programs so much more desirable if your favorite celebrity endorses it, or gives shout outs to the gurus for their "amazing work". Here's one quick example: https://www.youtube.com/watch?v=p2BCT01STn8

If you're comfortable with PHP, Shopware & Sylius (both built on Symfony). For Python, look at Saleor. If you don't want to live in a world of pain ( see looping__lui), use a SaaS solution like Snipcart or BigCommerce (which has very competitive rates vs. Shopify). Use the time to learn how to market your product, run ads, create content and grow your business.

Sylius should be seen more as a framework. And while it is full featured, it also is maintenance.

Reminds me of Big Sister [1], a brothel where customers could use the women's services for free, subsidized by paying Internet viewers, DVD sales & such.

Yep, but there the business model is (was) clear, there is no doubt that there is a (vast and lucrative) market for voyeurs and (streaming) porn, what is missing here is the lack (I presume) of a market for people wanting to see strangers sleep.

Maybe there is a subset of feticism about it, but are the numbers big enough?

tbh his ordinary, struggling budget hotel has given a handful of guests a discount, and in return he's got worldwide press coverage. I suspect that's the bit that matters more than the sustainability of the model.

Yep, but if he had an online shop, I would understand that, I simply (maybe it is just me) cannot see how/why anyone (being in Fukuoka) would choose that hotel over the competitors (paying the "full" rate I mean) so - maybe - he is increasing the number of people willing to stay there (watched) for 1 $ per night, i.e. something on which the hotel will loose money.
