The climate change debate continues.

Keeping warm and snug with a lovely coal fire this morning.

We'll have none of that in Hobart.

We like clean air. We banned them, and we have roving fireplace nazis that go around checking chimney temperatures to make sure. Fireplaces are so eighteen hundreds.

 

We use hydro powered home heating.

Whereabouts are/were you as the sale and use of coal for domestic use in Engalnd has been banned for ages. Often, where coas is allowed,  they will use smokeless processed form of anthracite..

Most modern houses ( in Australia ) are built without chimney & fireplaces .

Which means they ' catch-fire ' easily , as shown  news so often .

Cold night , just burn some sticks,  next to the plastic-foam three-piece suit.

In Scotland they still sell and use coal. The coal sellers have banner signs beside the road advertising it, 

 

I know at least one pub near Lithgow in NSW that uses a coal fire, I don’t know where they get it.

 

There is no smell inside, almost no smoke, but a wonderful smell outside that takes me back to the days of steam trains.

Really?

 

Everyone in our neighbourhood still has a wood heater.

I did specify Hobart town. I think you are well away from the city.

I believe the Hobart ban came in when the power company introduced a special low tariff for electrical home heating.

[onetrack]

The W.A. Govt clamped down on wood fires over 20 years ago. Not a ban as such, just regular encouragement to get rid of them. Unsurprisingly, there are still plenty of houses in the Darling Range and the S.W. of W.A. still using wood for heating and hot water.

You can tell where these areas are on cold still mornings, the choking wood fire smoke hangs around in the valleys for hours, making them quite unpleasant to drive through.

 

We have electric RC A/Cons, best thing since sliced bread, we got rid of the previous oil heater in 2005. The oil heater was installed in the original (wood) fireplace by the previous owner, so that was a long time ago, we've been in this house for 35 years in early June.

Scotland today

[Jerry_Atrick]

Hmm.. Just proves Scotland is a little backward in domestic heating fuel and the SNP are largely incompetent. Their own study concluded that coal and other high sulphur emitting fuels should be prohibited back in 2023

China plants kill switches in solar panels sold to the west.

There was another article in The Telegraph. It said to read this article, I had to enter my email. I have an anonomous email which I put in, and a screen came up asking for more information to get 30 days free access. Too much like a trap, so I scrapped it.

 

I did a web search "kill switches in solar panels". There are at least half a dozen possible hits.

Many of the original media articles are totally wrong, misleading, and alarmist. There are no "Chinese solar panels with kill switches", it's a huge beat up.

 

The truth of the matter is, some Chinese inverters have been discovered to have electronic components in them, that are not listed on the bill of materials in the components list.

 

This was only discovered when communication security checks were being done on Govt installations that had installed the Chinese inverters.

 

No-one has yet produced any evidence that the devices found were nefarious, had inbuilt shut-down abilities, or were even installed by the manufacturers. They could have been installed by anyone, anywhere, along the manufacturing, transport, or installation trail. The electronics experts are still trying to figure out the purpose and operational abilities of the devices.

 

They may simply be wi-fi devices that send back equipment usage information to the manufacturer to enable the manufacturer to determine usage methods, styles, modes, etc, that enables the manufacturer to gain insight into how the device is used, and to enable the manufacturer to improve performance, or to add desirable features to a new improved model.

 

I have a Canon printer that does just that. Canon ask you when you set the printer up, if you will allow the printer to send aggregated usage information and other data back to Canon occasionally, so Canon can identify methods of usage and modes, that will improve their knowledge of how the printer is used.

 

Every now and then, when I'm using the printer, a pop-up message appears saying the printer is sending information to Canon. All printer operation stops while this is being done (about 5-8 seconds), and then the the pop-up window disappears and printing operations can then be resumed.

Canon stress that no identifiable personal information is being sent to Canon - and really, I don't care too much if it is, anyway - what is Canon going to do with a small amount of information about me, that only relates to how I use my printer? It's not like it contains my licence or banking details.

 

If there are unspecified wi-fi devices in the inverters, that are used in critical infrastructure, then that certainly raises questions as to why they're not listed, and what they're capable of. I'm sure the electronics and communication security people will be right onto it. I'd have to say its simply a possible lapse in documentation - after all, the operations manuals will be in Chinglish!

Could and may . Very few actual examples. China Bashing? Nev

If the effing dumb western pollies weren't blocking innovation in the sector thanks to their desire to maintain fossil fuels, the west would have probably been ahead in the energy infrastructure manufacturing and could introduce their own alleged kill switches

I have 2 Chinese made inverters. Probably around 90% of all home rooftop solar systems have Chinese made inverters. As with almost everything you buy now you register the warranty and provide your Email address and other contact details. My units are connected via WiFi to my network and when I log in to the web enabled system to check production statistics that information is accessible if required by the manufacturer. I am pretty sure that the warranty registration process has this specified.

 

Everything I have purchased in the last few years has an on-line product registration process where your email and other contact details are stored. The manufacturer is more interested in selling more of their products and improving performance to stay ahead of their competitors than spying on you. In my case and it would be the same for the vast majority of other consumers of these products they would not find anything worth while & if they were able to do something even remotely strange and it was found out that would be the end of them.

My Chinese inverters send the data to Singapore. I can download very detailed consumption records.
