Overseas subscribers whose paper copies have been temporarily suspended due to coronavirus have been given temporary access to the archive, not Pocketmags, and have been sent instructions on how to access it.

Nothing received by me I'm afraid. My last Mytime email was in February relating to a subscription renewal

Thread: Covid19 - Overseas Subscriptions
26/05/2020 09:10:29

Apologies if this is covered elsewhere but I can’t find the thread.

A conversation over on the MEM forum touched on the delay those of us overseas are experiencing with the delivery of our copies of ME and MEW. I had just expected them to be delayed and at some point they would arrive.

Jason pointed me to Neil’s post on Forum and Martins editorial in ME which seems to indicate that although the magazines are being printed and delivered in the UK any overseas subscriptions will be suspended the magazines won’t be shipped.

If that is the case extremely disappointing, these magazines have ongoing articles that people could be following, others have complete sets of the magazines going back years, there will now be a gap in those collections, which may never be filled.

Suspending our subscriptions isn’t the solution. Overseas mail services may be delayed but they haven’t been suspended so why can’t the back issues be bulk shipped at some point?

In the meantime, please give all the overseas subscribers free access to the digital issues, back dated to March. It not going to cost you anything and you’ve already got our money.

Crisis? What Crisis?

With all the talk of self-isolation I thought it time to sign up for home deliveries from the local supermarket. Let’s start with essentials….

One of the benefits of living in NZ, only 202 Pinot Noirs to choose from. When can I start?

Just got back from the supermarket. As expected there is no toilet paper, no worry. There appears to be a run on the alternative - tinned soups and tomatoes!

No doubt by Tuesday there will be so much toilet paper that it will be stacked in the car park.

JA

I visited the local supermarket late on Friday, expecting "Hell's Grannies" with handbags drawn to find pallets of the stuff in the entrance way.

But toilet paper??????
you obviously haven't had the experience of finding a loo, getting relief and then finding no loo paper left in the holder! - maybe a gender ordered thing ?

Maybe the gender thing is checking before you commit?

The map apears to be updated at the begining of each week. NZ now have 3 cases and the run on toilet paper has hit the masses here.

Peter

I've no idea what happend to the images

The clue is in the drawings and instructions for the Bobcat that Malcolm did after the Lynx, just scale for the Lynx valve heads. Make the blank valve seat/guides insert in the head and then drill the ports. It looks like I also included liners for the spring pockets, probably unnecessary.

Thread: Cheapskate Sandblaster

HEALTH WARNING

Sand should no longer be used for blast cleaning unless proper breathing aparatus is used, not just a mask. Sand contails silica and breathing it is bad for your health. Workers who breath in silica dust could develop chronbronchitis, emphysema or acute silicosis.

Yes I have garnet in my small cabinet blaster and wear a 3M respirator and hooded overalls as dust still gets out. I made the mistake of not wearing overalls once and after I took off the respirator started breathing the dust in my clothes.

Much as I had suspected, a total loss solution and cost effective if you live near a beach!

As for removing machining marks and other minor imperfections that's certainly one of the benefits of blasting parts. Far quicker than trying to blend with files and wet and dry. If you want a good finish give the job give it a blast, and then start with the wet and dry. Otherwise a great base for the etch primer. Just make sure all the running surfaces are well protected.

I've got one of the small cabinets and even though it is enclosed quite a bit of dust gets out. I've looked at these open air systems but have always wondered how much mess they make.

Although you are using kiln dried sand in your Kartcher I assume it runs wet so you soon have a pile of wet sand? Does that help contain the dust? Can the sand be adequately dried out to re-use it?

What is your experince?

More from Transpower. This time their views on battery storage from a grid owners perspective.

**LINK**

The conclusion being that its better done at the consumer end of the network. Which aligns with suggestion of using your EV as a battery backup and to feed power back to the grid. You EV probably has the biggest battery you own.

What it does to the lifecycle of the battery is another consideration.

I don't see renewable energy as a one-for-one alternative to fossil fuels. Instead I see them as a way of softening the blow. Ideally most people most of the time can carry on. Otherwise, given time, people always adapt to what's available.

Thats exactly what Transpower said in their document that I quoted

We will see the mainstream commercialisation of distributed solar, electric vehicles and energy management systems. These will start to significantly change the profile of demand and operation of the system with solar and batteries as well as other distributed energy resources enabling load to be partially flattened within a day but also adding additional intermittency. Despite growth in distributed supply, there will also be significant growth in grid energy demand. In the short and medium term we do not expect these batteries and distributed energy resources to be sufficient to flatten the daily or annual load curve, however it has an important potential to shave off peaks and it is critically important that it doesn’t accentuate existing peaks and troughs

Love the leccy cars. I want to go visit a mate in Adelaide, next state over. Battery Cars have range of 250 km / 160 miles, Adelaide is about 2700 km from Perth, 10 charges if it were possible. On the Eyre Highway / Nullarbor fuel stops are about every 300 km with NOTHING in between, run out of power 50 km before next service station, WONDERFUL. My petrol car has a range of 500+ km. I usually get there in 2.5 days with 2 overnight stops, 1100 km per day as I do not hurry.

But it may take a while and the wife and kids will have to fly..........

On a serious note it is encouraging to see that the we are now seeking formal documents on the subject rather than trotting out 'she'll be right', wind, solar, batteries and smart chargers will sort it...

My favourite pub topic. As member of the Institution of Engineering and Technology and retired electricity distribution engineer, you are pretty on the mark. Apart from the total required generation, the 415volt cables in a street full of electric cars coming on line at the end of a working day would be a disaster ! In the best scenario, the fuses at the local substation would blow, given a very high load or worse, under a more modest overload would cause cables to overheat and fault permanently. In my opinion, the drive for "smart meters" is to enable tariff boosts or, even, disconnection for load sheding to control this.

I would be more than enthusiastic to see all electric vehicles but it requires an astronomical investment in the electriicty infrastructure.

David

I'm with you. A case of "The Emperors Clothes”.

At some point the stakeholders are going to have to wake up and realise that it is time to take this seriously rather than the piecemeal solutions that are being bandied about.

From Transpower the NZ grid network owner

**LINK**

" We will see the mainstream commercialisation of distributed solar, electric vehicles and energy management systems. These will start to significantly change the profile of demand and operation of the system with solar and batteries as well as other distributed energy resources enabling load to be partially flattened within a day but also adding additional intermittency.

In the short and medium term we do not expect these batteries and distributed energy resources to be sufficient to flatten the daily or annual load curve, however it has an important potential to shave off peaks and it is critically important that it doesn’t accentuate existing peaks and troughs."

and

"Many of our existing assets will need significant investment in the next couple of decades. The assets of greatest concern are the conductors on some of our key 220 kV lines, many of which are built over urban areas. We need to sequence them carefully to manage our and our contractors’ resources, to avoid volatility in our transmission charges and to ensure sufficient capacity headroom to enable the grid outages required for the work.

Further future opportunities exist. New tools leveraging our data using learning algorithms such as artificial intelligence will increasingly play a role in managing the network as a complement to the distributed energy resources in individual homes and businesses. The increasing storage in the network could eventually create a network with extensive storage in which the grid’s role shifts."
