  1. Hope they are sent down for a very long time. From my musical perspective I do love the headline "Wagner (pronounced Vagner) accused of orchestrating".
  2. Agreed. Audimed also do Oticon which is, in my opinion, the rolls royce of hearing aids. I am intimately familiar with Adimed having been a customer for quite some years now. They also do AB cochlear implants but a better choice would be Med El which is also in Bangkok.
  3. If it's any help to anyone, I get all my water filter equipment from here:- https://www.duan-daw.com/ I have never had any problems with stuff bought from them.
  4. Many years ago I also got involved in clamping up electrical connectors. Admittedly we aren't talking of multicore copper cable, but the rules are probably the same. We were designing the copper busbars for an electroplating plant in South Korea. The copper busbars were somewhere in the order of 200mm x 15mm. These were the small ones inside the transformer cabinets. The busbars needed to be bolted together with six bolts at each joint. We were to ensure that the bolts were not done up too tight. Copper has a bit of elasticity which is lost if the pressure is too great. This elasticity is important when taking into account temperature changes. As copper cools, it gets smaller so an overtightened joint becomes looser. This looseness gets taken up by the natural elasticity if the joint is done to the right torque so the correct amount of tightness is important. It pays to check yer nuts periodically.
  5. Have you got your grandchildren staying too?
  6. No comprendo. On 30/05/2025 consumption was less than production yet you still took in quite a bit from PEA. ??
  7. Kitchen hygiene is sometimes a little lacking. Easy to get diyaria......
  8. Well done Cambodia. Keep up the good work.
  9. He is a malingerer. The picture was taken to deliberately make him look his age in order to garner sympathy and understanding for his fragile disposition.
  10. Just to be on the safe side I have sketched up a schematic of a combiner box.
  11. The world steps back away from the threat of WW III and leaves Putin free reign to wage war how he likes? Putin will carry on issuing his WW III threats safe in the knowledge that the worst case scenario is a few more sanctions which don't seem to be very effective.
  12. Thaksin wants to lecture the medical council on ethics? Mr. Thaksin. You have to be joking.
  13. It's worth remembering that the panels, by their very nature, are current and voltage limited. The fuses, surge absorbers and breakers normally fitted are more to protect against lightning EMP (electromagnetic pulse) events. The fuses fitted are normally "quick blow" which is considerably faster than a circuit breaker. The scenario in the event of a lightning surge is: The EMP will cause a high current flow in the solar panel wiring. The surge absorber conducts this high current to ground. This high current causes the fuse to blow very quickly. A second strike nearby will go nowhere because the fuse has already blown. House and inverter et al should never see any dangerous and damaging surges. Having said all that I've never heard of such a disastrous event happening but sods law being what it is .........
  14. I think everybody who heard Trump's 24hr fix for the war knew it was an utter rubbish thing to say. In my opinion Putin is hell bent on reassembling the USSR. He can only be stopped by being beaten on the battlefield, and that is something no one wants to get involved in.
  15. And yet the super rich are not necessarily the most obese. I think it has less to do with money and more to do with education.
  16. This is what a PV combiner box should look like. If the box only has one input and one output then it is not combining anything. This one is advertised on Shopee. I am showing it for illustration purposes only. https://down-th.img.susercontent.com/file/sg-11134201-7rd6t-m6y0sney5yu36a
  17. Ooops. For UK please read US. However, it might be a worthwhile exercise to take a quick look inside inverters in other countries.
  18. Eh? I'm not even going to attempt to translate this rubbish. It's worth remembering that grid connected domestic inverters in Australia are mandated to have coms facilities fitted so that grid controllers can modify outputs to suit the grid requirements. In this article, no explanation is offered as to the probable purpose of the communication equipment. At best it seems that the inverters were not to spec. At worst there is the possibility of foreign control of the UK solar grid.
  19. This is just like the stuff Bob used to write. Is he still about?
  20. I have no idea if there is a better place to post this question so please move it if necessary. When a foreigner dies in Thailand what sequence of events gets triggered and who is responsible to make sure it happens? Is there an agenda followed like; Hospital autopsy to determine if there was foul play, Immigration police to cancel visa etc. Local police to contact embassy of deceased. If anyone has experience of these matters, it would be good to hear it.
  21. The key word here is "coherent" which is under scrutiny at the moment.
