The main issue is with longevity, once they solve that, I am hopeful they will then this will dominate the Solar market completely and replace all the Silicon based single band gap panels. Even someone with relatively recent panels of 20-22% would benefit a lot from 35% panels, that is a lot of extra power in the same space.
I have done this a few times, so long as the drive isn’t mounted it works fine.
One advantage of this approach compared to clonezilla is you can pipe it through netcat or similar and move it to another machine. You can also first pipe it through gzip as well to save on the transfer bytes a bit as well and then on the other end just store the compressed image or unzip it. Combine a few tools together and you have quite a lot of capability for complete image backups but its usually best done for the boot drives from a live USB.
Metube is great and also has some browser plugins as well so it’s as simple as right click and send to metube on a YouTube link. Wish there was one for android too but alas not yet that I have seen.
Late last year they were talking about $40 for a KWH which compared very favourably to LifePO4 that was more like $130 at the time and Li-ion that was more like $200. However right now on alibaba you can get a 200Ah battery for about $60 and the LifePO4 300Ah are now down in the $50 range which is an incredible drop in the space of 6 months. So in practice they are less dense and more expensive but I think its new technology introduction pricing and at some point it should be about a third cheaper than LifePO4 for the same capacity, all be it a bit bigger and heavier and quite considerably cheaper than Li-ion for the same capacity.
The small 18650 and other small sized cells have started appearing on aliexpress as well so its possible to get those too butt they are a lot more expensive than a basic Li-ion 18650 at the moment for a lot less capacity. I think its mostly the bigger cells that most people interested in Sodium Ion will be wanting (home battery and grid storage solutions and some of the low/mid range cars) more than small cells since typically the smaller stuff you want to maximise capacity even if it costs a bit more and most will want li-ion and ideally the newer nearly solid state li-ion that doubles capacity per KG.
Most of the cookie banners are breaking GDPR. The requirement under GDPR is that privacy must be the default and users can select to opt in. So most of the banners you come across that default to all tracking are against the law already. The legislation didn’t stop them being annoying in this way but a few prosecutions for the breaches and dark patterns would set things off on a better path.
The EU law explicitly says no consent by default and users have to opt in. All of these cookie banners are breaking the law, the law doesn’t need to change it just needs enforcing and these banners will disappear. We already have a do not track header and that could be complied with but it’s enforcement that is the problem.
I tend to go off the https://grid.iamkate.com/ website which is a good day by day look at power generation and summarises the year. Renewables have so far surpassed fossil fuels 10.7GW compared to 10.3GW with other sources taking 5.9GW of which biomass is 1.52GW. I don’t personally think biomass is renewable because its burning old forests and at a rate far faster than the wood is replanted and we know that old forests store much more CO2 than new ones. With hydro and Nuclear its a pretty close run thing if we consider them green renewables are the majority of power production.
Still a way to go, obviously more capacity is required and more storage and this will inevitably lead to excess power in the summer which is how renewables will work and hopefully we will find a good use for free power capturing CO2. A lot of projects are held up by the grid in the UK, more than enough to complete this transition, companies want to install the production its just the grid holding everything up with plans out to 2035.
I can see in the future a standard for DC power with a completely different power socket that saves up the round trip of DC to AC then back into DC for all our electronics. There are fairly substantial benefits to be had but as I think it through the usable DC is 3 to 12V and appreciable load will mean those cables will push a lot of amps. Not sure the economics will work out without it being high voltage and that fits nothing DC today. If it’s high voltage then everything needs a converter again.
Setting a DC standard today will be a world wide nightmare, we need it but it’s got to be dumb for longevities sake. It’s far off I think.
Its not directly in the article but the primary reason Solar is its a lot cheaper than electricity production from fuel, something like 1/4 - 1/10 the price depending on where in the world you are. An energy company is basically foolish to invest in oil based electricity production when Solar is so competitive and cheap and easy to maintain. Wind is a little cheaper where there is good airflow but the maintenance cost is higher especially for offshore. Both however are so much cheaper than Nuclear and especially than oil/drilling fuels that its hard to see much real investment in those older technologies.
There has been a lot of recent complaints around the UK’s granting of further drilling rights in the North sea for Oil. I think the companies taking those up haven’t yet come to terms with the fact there is a good chance those ventures drive their companies to bankruptcy because they wont be competitive as EVs and Solar/Wind take over due to cost savings.
A change in thinking about energy needs to happen to truly understand why Wind and Solar and a bit of storage is enough. You have to accept that at times there will be overproduction of power because storing it to hit exact use capacity isn’t cost effective. Some storage makes sense, but its much cheaper to have more capacity.
What I think will happen in the future once we reach the point this is how most energy comes is more people will be on Octopus like smart energy schemes where you might get paid for using electricity and there will be companies that use this to remove CO2 from the atmosphere. We are approaching a world of energy excess but only at certain times and there are opportunities to use that energy for the right reasons to reverse the damage we have done with CO2 emissions.
Not really, they are using public money to pass it into private hands. Its capitol but not in the way capitalism describes it because its not coming from wealth to invest in new ventures its being extracted and pocketed.
Guess he doesn’t have any investments in Tobacco, or he has investments in Vaping.
I do both. I have a custom built NAS based on a Ryzen 3600 and ZFS across 4 drives which runs about 20 self hosted applications and stores the majority of my files but its only accessible from within the home. I also rent a small VPS for personal webspace and hosting self hosted apps I want out of the house.
In the past I have also hosted raw servers from Hetzner or bigger VPS from Amazon for the purpose of hosting a game server. Alongside those I often had community applications like website, forums, wikis and custom chat and voice comms services.
Its all self hosting to me since I run it. The various options are all about the trade offs of security, accessibility, cost and performance. The cheaper cloud options when you add it up can be cheap compared to buying and running your own hardware when you take into account electrical costs and the likely hardware replacement needs within 5 years. The big cloud providers aren’t price competitive but Contabo/Hetzner really surprisingly are especially if you pay a lot for electricity. But then if you need a game server it can be quite hard to find good fast CPUs on the cloud and its not going to be 24/7 for communities, so the trade off flips back to having your own.
Since I got 1 gbit/s fibre internet my need for internal NAS has definitely reduced as the internet is nearly as fast as the local network so I could now have my NAS needs remote.
Even the main search engines don’t index the entire internet of content these days and their databases are truly massive already. Writing a basic web crawler to produce a search index isn’t all that hard (I used to do it as a programming exercise for applicants) but dealing with the volume of data of the entire internet and storing it to produce a worthwhile search engine however is just not feasible on home hardware, it would be TB’s at least. It wouldn’t just be a little worse it would dramatically worse unless you put substantial resources to it including enormous amounts of network bandwidth which would have your ISP questioning your “unlimited 1 gbps fibre” contract. It would probably take years to get decent and always be many months out of date at best.
Doesn’t seem practical to try to self host based on the need to download and index every single page of the internet its a truly massive scale problem.
Over the years I have used OSMC for my TV. I have never used it for streaming however always internal across the network streaming of my own content. It worked reasonably well for the most part although I have had issues with Samba in recent versions and have stopped using it. I can’t say much about its streaming, mostly for that you need a supported android or similar device rather than an open source one.
