NIST trains AI to hear the 'oh crap' moment before batteries explode

Re: "find its way into homes, office buildings, and [EV] parking garages"

Last year there was a similar fire in a multistorey car park at Luton airport. It turned out it was caused by a diesel Land Rover. So don't assume EV every time you hear of a car fire.

Statistically they are less likely to catch fire than diesel or petrol, but as the article suggests, when they do, the intensity is far greater. Some fire departments don't even try to put the fire out anymore because it is close to impossible, merely controlling the fire and preventing it from spreading.

But it is worth mentioning that modern lithium batteries have temperature sensors that can detect a thermal incident and alert the user.

Affordable, self-healing power grids are closer than you think

Re: Intermittent generation

The electric grid is becoming less centralised with more and more generation (solar, bidirectional charging) happening at the edge of the grid.

There are trials of new-built homes with solar panels and included energy storage which are managed by the grid operator that are being sold with zero ongoing costs because they help balance the grid. Lookup zero bill homes from Octopus

Re: Batteries

I recently read about the Tesla grid-scale batteries doing a virtual inertia to keep frequency stable, so it can be done in other ways. It is beyond my paygrade though...

Re: 120 kWh a day

Heating / Gas only numbers.

The numbers are very clear in the smart meter history.

This includes hot water but that's only a very small part during winter months

Re: Intermittent generation

Some heat pumps are reversible and can be used to cool the property in the summer. It's not very efficient though, maybe a couple degrees C temperature reduction, because of the low convection rate with "normal" radiators. There are "active" radiators with fans on them that would improve that.

Re: 120 kWh a day

Educated guess? Hilarious!

120 kWh a day for heating a semi-detached house!?

I live in such a house and can tell you the most I ever used was 46kWh on Jan 20th. Presumably it was very cold that day because the winter average for me is well below 30kWh per day. December average was <20kWh per day but it was an unusually warm month.

Re: I don't remember learning this in economics!

The cyber business (relatively new venture) has been making massive losses every year. They're complaining about tougher competition in this space and not being able to compete on price.

The registry business (.uk) has always been highly profitable due to it being a natural monopoly. They want to increase prices for the registry to make up for higher losses in the cyber.

I say cut the losses and stop messing about with these bright new venture ideas that each CEO and Board come up with every few years.

Raspberry Pi on IPO plans: 'We want to be ready when the markets are ready'

Re: And what could possibly go wrong

An IPO would raise capital for further investment and potentially diversification of the product lineup.

Though I would be inclined to think that, considering how loyal and supportive the RPi user base is, similar capital could be raised through some form of crowdfunding.

I know I would pitch in or prepay for the RPi6 a year or two before its launch in order to support its development.

Re: Some people...

Of course this type of tariff is not for everyone, but it is a sign if things to come. That's the reason behind smart meters rollout.

I was already an Octopus customer for some time and they have the option to compare all your smart meter usage data that you have with them against the historical Agile prices and get an estimate of what you would have paid for that period if you were on the Agile tariff. In my case, it came out 30% cheaper, mostly because I'm almost never at home during peak hours.

| Why is there a penalty at the peak period?

That's when there is the highest demand on the grid. All those people getting home from work and putting on the kettle or turning on the oven. To support this extra load, the National Grid usually resorts to expensive gas peaker plants.

| Why is there a 100p cap?

Presumably to give some reassurance to customers. It's better to do this benevolently, rather than have Ofgem write special rules for your unique tariff.

| How well does Agile reflect renewable supply?

Very closely, but there are some surprises. For example I sometimes get free energy when there are strong winds (like the other day with storm Isha) but during those times the national Agile tariff can still be quite expensive.

As far as I can tell that is because of the location of renewable generation and the lack of transmission lines capacity to shift that surplus to where it's needed. So, because I have solar and wind farms nearby, I'm incentivised to use as much energy as possible rather than them having to shut down generators and pay them penalties (curtailment).

It's an interestingly complex topic and I've only just started digging... :)

Re: Some people...

Fair point. A wash cycle should cost way less than £1

I did my units wrong and confused W with kWh

But the point remains: the difference in price of the Agile tariff between the cheapest and the most expensive time of the day can be 3-10x

Occasionally the price can even turn negative, so you get paid to use electricity

Re: Some people...

That's similar, yet entirely different.

Look up Octopus Agile:

Re: Service with a smile

You don't need a "smart" appliance for this. Most will return some kind of error code which the owner can relay to the customer service or engineer.

I had an incident like this...

The engineer came over knowing exactly what the problem was, based on the error number and my description of the symptoms. However, due to their internal processes he couldn't preorder the needed parts. So he had to come over to confirm what the problem was, then book another visit a week later to come back with the replacement parts.

That might have been a Samsung "smart" washer, but it was a dump process...

One guy gets it...

Some people...

Some people love to hate anything that is turned "smart", especially white goods, but fail to see the actual reasons and benefits of doing this.

With the smart meter rollout, we are gradually shifting towards time of use tariffs for electricity and this will mean we will load our washer or dishwasher, press a button and it will run the wash cycle whenever the energy is cheapest or the grid has extra capacity. I occasionally get 2-3 hours slots of free electricity from Octopus and the remote start function is perfect for that. But I also have their Agile tariff (every half hour has a different cost per kWh) and an automation on my Home Assistant turns the wash program on when a certain number of consecutive hours of cheap electricity begon ,usually around 1-4am. Of course, the washer needs to be loaded by me first and I must enable remote start and leave it pending.

Of course these appliances don't need internet to achieve this, just some sort of API, ideally completely local. Until now every manufacturer did their own thing, their own integrations and partnerships with smart meter companies, etc. But finally it looks like there might be a common standard on the horizon: the Home Connectivity Alliance.

The "smart" functionality for these appliances can be a very basic chip like an ESP32 which in turn activates a relay and confirms the operation and state, so it needs not to be expensive. It can recover its cost quite easily. For example, I did some rough calculations and the "smart" remote control/start on my dishwasher can save up to £2 per wash if it runs when the electricity is the cheapest compared to when it is most expensive during a typical day.

Apply the same logic and functionality to something like a heat pump and the savings really add up.

Re: please forgive my lack of knowledge...

Most data will be SSL encrypted, so it won't be a trivial thing to do.

Use a Zigbee or other wireless switch an place it right next to the door. Batteries for that last at least a couple of years.

Save your phone battery.

Use a Bluetooth iBeacon.

Your Home Assistant will know you're home just before you step through the door and turn the front door light for you if appropriate.

This is one of the great things about Home Assistant is that you can achieve the same outcome in so many different ways with so many different type of sensors.

Yeah, but...

I love Home Assistant, but while itself is very privacy-focussed, it is often relying on 3rd party integrations that have their own loose privacy policies.

So my HA for example talks to the Google Nest and Bosch/Miele API which have been mentioned in this article.

UK government hands CityFibre £318M for rural broadband builds

Re: That's a lot of money

Well, yes. But that's the cost of install for a single dwelling.

The transport of equipment onsite, the planning and council permission, some of the trenches and ducts, all of that would be shared by a larger number of homes and would expect to bring the cost down significantly.

If I call BT to dig up my street to install fibre just for me, then yes, I expect that to be quite expensive.

That's a lot of money

Almost £2,000 per household to get fibre broadband?

Another redesign on the cards for iPhone as EU rules call for removable batteries

I think it was for privacy. I remember there were reports in the news or maybe just urban myths that a 2G phone could be remotely turned into a listening device and this caused a lot of people to be concerned when discussing sensitive topics. The safest thing was to remove the battery

They are tools

Exactly! Your analogy to a hammer is very pertinent.

Once you start looking at things you use every day (phone, laptop, car) as tools, your whole attitude to buying them and using them changes.

I'm not convinced this legislation goes far enough, but user-swappable batteries in smartphones, similar to the ones we had in the 2G era, might actually result in smaller phone dimensions if you could have a fully charged battery in your glove box or your laptop bag which you could swap in seconds.

Because your ignorance has an impact on all of us and our environment.

It is not worse. You don't see anyone complaining that remote controls use AA batteries, or that all TVs have this HDMI port, or that all cars must be Euro6, etc.

Mine is rated for 150m

I can replace the battery myself, but because it lasts for >5 years I prefer to give it to a professional to do it and get a warranty for the work since I wouldn't want anything to go wrong while 30m bellow the sea.

The EU in not choosing for the consumer, it is only setting rules to protect consumers.

Every government does this for their citizens to varying degrees, but the EU takes this to completely new levels.

Offshore wind power redesign key to adoption, says Irish firm

Balast

This looks like a clever design, but moving elements and pulleys in those harsh conditions don't seem like a good idea.

If something fails you don't want the nacelle with its tons of oil other dangerous chemicals landing in the water.

To keep something that floats stable in rough seas you need balast. Lots of balast.

Finding cheaper and more suitable balast sources would seem like a better direction of research to me, but nonetheless it's good that research and innovation is happening in this industry not just on the blade and generator front.

Hey Apple, what good is a status page if you only update it after the outage?

At Nominet, the "heart of the internet" as they like to call themselves, the status page is almost never updated.

On three occasions I've had to specifically ask that they put some sort of update on nominetstatus.uk after reporting an issue to them, them not being aware of it initially (at least 1st line of support weren't) then later confirming it was a "wider" issue.

Sure, an EV is probably not right for you yet.

But it is right for most people in Europe if they weren't so darn expensive

While technically H2 and CH4 are very different and pose different challenges, I agree with the sentiment of your comment: we've proven as a society that we can work with extremely dangerous gases even in a domestic setting without any special training.

Plus we've been using hydrogen in industrial settings for the production of ammonia/fertilizer for over a hundred years.

Some second hand EVs are actually appreciating in value (accounting for inflation)

This is unsustainable, I think, and can't last for much longer.

But the old rule of thumb that a second hand car halves in price every two-three years is definitely not applicable anymore. Be it EVs or ICE

A hydrogen tank does not explode in the event of a car crash, for example. It probably would in the event of a terrorist attack, as you suggested. But so would petrol tanks in that case.

Toyota engineers (big proponents of hydrogen fuel cell cars) did plenty of tests and they admitted that they were surprised by the results: in a high velocity crash where the tank would be punctured the pressurised hydrogen is released in the atmosphere with incredible speed and it immediately raises up before it can ignite.
