  1. You don’t have to be an engineer to appreciate this story. A toothpaste factory had a problem. They sometimes shipped empty boxes without the tube inside. This challenged their perceived quality with the buyers and distributors. Understanding how important the relationship with them was, the CEO of the company assembled his top people. They decided to hire an external engineering company to solve their empty boxes problem. The project followed the usual process: budget and project sponsor allocated, RFP, and third-parties selected. Six months (and $8 million) later they had a fantastic solution - on time, on budget, and high quality. Everyone in the project was pleased. They solved the problem by using a high-tech precision scale that would sound a bell and flash lights whenever a toothpaste box weighed less than it should. The line would stop, someone would walk over, remove the defective box, and then press another button to re-start the line. As a result of the new package monitoring process, no empty boxes were being shipped out of the factory. With no more customer complaints, the CEO felt the $8 million was well spent. He then reviewed the line statistics report and discovered the number of empty boxes picked up by the scale in the first week was consistent with projections, however, the next three weeks were zero! The estimated rate should have been at least a dozen boxes a day. He had the engineers check the equipment, they verified the report as accurate. Puzzled, the CEO traveled down to the factory, viewed the part of the line where the precision scale was installed, and observed just ahead of the new $8 million dollar solution sat a $20 desk fan blowing the empty boxes off the belt and into a bin. He asked the line supervisor what that was about. "Oh, that," the supervisor replied,” Bert, the kid from maintenance, put it there because he was tired of walking over, removing the box and re-starting the line every time the bell rang.”
  2. I've had calls from German, US and UK numbers recently, I don't answer, just decline and block. Anyone who needs to contact me has at least one alternative to phoning.

    Water Pressure?

    Only after the beer has been processed by his kidneys
  4. Running a centrifugal pump into a closed valve is unwise. It's not likely to rupture your pipework but all the energy that's going into the pump will be converted into heat warming up the water that's inside the pump. It can get very warm! Is the holding tank close enough to the well to run an overflow back to the well?
  5. It's fine with iPlayer on both PC and Andyroid. I've never had a lot of luck with "smart" TVs, they tend to be under-powered CPU wise ???? You can connect using a lot of routers and use the router to decide which devices use VPN and which don't.
  6. Yup ^^^. VSF with its many fine strands is much less of a wrestle, but it really needs ferrules on the ends.
  7. We use Ivacy. Quick, reasonably priced, servers worldwide, decent solution for BBC iPlayer. EDIT And support responsive!
  8. I only use TrueMoney (linked to my credit card) at the Seven but do they accept credit cards at the counter?
  9. QR scan ???? (sa-kan) Either PromptPay via your bank app or TrueMoney Wallet. Note that TrueMoney only works in Makro if it's funded by cash not by a credit card (even a Citi one).
  10. A young doctor had moved out to a small community to replace a doctor who was retiring. The older doctor suggested that the young one accompany him on his rounds, so the community could become used to a new doctor. At the first house, a woman complains, "I've been a little sick to my stomach." The older doctor says, "Well, you've probably been overdoing the fresh fruit. Cut back on the amount you've been eating and see if that does the trick?" As they left, the younger man said, "You didn't even examine that woman? How'd you come to the diagnosis so quickly?" "I didn't have to. You noticed I dropped my stethoscope on the floor in there? When I bent over to pick it up, I noticed a half dozen banana peels in the trash. That was what probably was making her sick." The younger doctor said "Pretty clever. If you don't mind, I think I'll try that at the next house." Arriving at the next house, they spent several minutes talking with a younger woman. She said that she just didn't have the energy she once did and said, "I'm feeling terribly run down lately." "You've probably been doing too much for the Church," the younger doctor told her. "Perhaps you should cut back a bit and see if that helps." As they left, the elder doctor said, "I know that woman well. Your diagnosis is almost certainly correct, she's very active in the church, but how did you arrive at it?" "I did what you did at the last house. I dropped my stethoscope and, when I bent down to retrieve it, I noticed the vicar under the bed”.
  11. All the Makro's I've used accept Thailand issued Citi (now UOB) credit cards and have done for some years. Not sure about other cards.
  12. Whilst it does produce AC, it's the phase of that AC relative to the mains voltage that tells the inverter which way the energy is flowing. It definitely matters which way round it goes. But you are right, it could well be on the wrong wire.
  13. I wonder if (like others have said) your CT is on the wrong lead or is the wrong way round. Definitely time to get your installer involved.
  14. Do you have a normal disc-type meter or an electronic one? The disc meters actually go backwards when exporting so it's easy to see. By the way, one member has been waiting >2 YEARS for his export meter!
  15. Certainly not impossible, but every inverter malfunction I've seen actually stops it generating (usually with a significant bang and the release of the Magic Smoke). If anything our GTIs (which are on the MEA and PEA "Approved" list) are a little too enthusiastic about shutting down on minor grid disturbances, although they come back up again within a minute or two. To address the fears of potential solar users I've actually looked into injuries (or worse) caused to linemen by correctly installed grid-tie solar. I've found none. There are a fair number of instances of people hooking up gensets incorrectly (no transfer switch) and back-feeding into a dead grid causing deaths! But in all those cases the lineman in question (or his team-mates) had made an error (or taken a shortcut) in isolating and grounding out of the lines.
  16. Back-feeding a dead grid is indeed deadly and very illegal! Every single domestic level Grid-tie inverter has island-protection built-in to prevent just that situation from occurring. Grid goes down, inverter shuts down. Exporting energy to a live grid is a different situation altogether. The inverter generates slightly greater voltage than the grid and energy flows to the grid.
  17. Since they likely use more than 300 units in total it won't make any difference to their costs. If you use less then 300 units you won't get any advantage either ????
  18. There's finally been an announcement, of course no actual detail other than it covers January to April 2023.
  19. It looks like they are continuing the reduced FT rate that was introduced last year. We got a refund of the FT that was deducted in January.
  20. As a kid brought up on the Apollo program and Fireball XL-5 these videos never cease to amaze me. Arthur C Clarke may have invented the communications satellite but Gerry Anderson invented the reusable spacecraft. All we need now is horizontal take-off and single stage to orbit. That booster has flown (and landed) 12 times! And for those too young ... And just how like XL-5 does the Space-X Starship look??
