This article headline is a gross abuse of the conclusions of the actual study which is here: https://www.eurosurveillance.org/content/10.2807/1560-7917.E... This site is full of people perfectly capable of reading

It is in a utility room with some normal fire resistant features, walls are block and the electric inverters are mounted to cement board. The batteries cells themselves are in the steel cased battery boxes which help to limit potential fire

Absolutely. Clouds also have a profound effect on solar output, I think much more than people realize. I am not english but my understanding is that london has a lot of clouds.

That is a much more complex topic driven by the regulations where you live. Where my house is, there is more or less no regulation and you can do as you please. In a purely technical sense there is not a lot of knowhow beyond basic electric

This area has few days over 100 but does see relatively cool nights. It is an ideal area for this. I would say from southernmost california to southernmost texas, this basic setup is pretty workable and that includes something around 50 mil

My battery is 3 separate "48v" x 280ah units in parallel. There is no grid so I am not sure what you mean by coupled. The batteries output DC to inverters which output AC. It is several years old at this point, probably the better

People seem to get really mad and accusatory over these sorts of things which is why I hate posting brands and such. The information changes very frequently as to what the "best" offer is. The diysolarforum is a very good resource

In it's location the solar is very effective, the 4kw is the actual generation rather than a label rating. 100% full sun, no shade, no clouds. The array typically generates over 20kw per day. The house is pretty efficient and the weath

If I had to recommend in all in one kit, this september 2025, I would recommend an EG4 kit from Santan Solar. At brief glance they appear to be a stronger value and is from a company with a pretty strong customer service record. This is not

I did not name specifics because things are constantly changing in this market and these threads tend to live for years. Stock and prices are constantly changing but RUiXU, EG4 and EcoWorthy are widely available brands with UL listed option

In that part of southwest there are only a handful of cloudy days per year and at a relatively low latitude.

I have a home in the southwest that is offgrid and runs entirely off solar. It has a 43kwh battery that covers 100% of it's needs including AC. It has a 4kw solar array. The batteries shipped to your home inclusive of all taxes and fee

This is a sketchy article about a study which is not even named because it has not yet been presented. It will be presented in the next week. I would take this entire thing with a grain of salt.

The article differs substantively from the actual conclusions of the study. This study shows a minor correlation in some bacterial DNA "signatures" in arterial plaque in about 200 people (~40% had the correlated bacteria). The stu

One of the hugely important takeaways of this study is that even though the therapy was applied at the site of the most significant tumor, the immune response appeared to trigger against presumably ALL tumors throughout the body.

I have a home in the southwest that is off grid and runs on solar plus lifepo3 batteries. It has been 5+ years now. My cost per kwh is below $0.008 as of today including all capital and maintenance. These numbers get a bit complicated, for

This also makes it infinitely more useful for healthcare. Not healthcare software specifically. Lots of use cases in logistics, irl maintenance, etc. Patient data creates hipaa challenges and tends to overflow into any system.

This is a study done on cell cultures. It should NOT be used to influence behaviors regarding human health. The article linked makes a lot of leaps not supported by the study itself. Link to actual study: https://journals.physiol

FOBT which you can do painlessly at home for a few dollars is not meaningfully less preventative than an invasive colonoscopy and carries almost no risk. https://www.nejm.org/doi/full/10.1056/NEJMoa2208375

Even with tariffs batteries are very cheap. Into the 4 year mark my cost per kwh is down below $0.02 because I end up using excess power for all sorts of things because it is "free". https://news.ycombinator.com/
