  1. Well actually he lost his rights to anonymity the moment he became a public figure.
  2. Builders in Thailand often locate the earth rod under the house where you can't access it. To verify it's existence, simply stick a bit of rebar into the ground close to the house, disconnect the house from utility supply and with a cheap multimeter set to read Ohms, measure the resistance between CU earth and rebar its should be no more than a few ohms.
  3. An RCBO looks at the difference between currents flowing in the live and neutral wires. Depending on the setting of the sensitivity of this device the RCBO will trip if a current of 30milliamps to 10 milliamps is flowing more in one wire than the other. This minute current can flow through a body and cause the RCBO to trip thus disconnecting power before harm is done. Earth is not needed for this. The person who contacts the faulty equipment is quite likely grounded enough.
  4. In my opinion the government should mandate the certification of electrical contractors and make it illegal to do electrical work without using a qualified and certified contractor. Certificates are required for tree fellers so why not for other trades too?
  5. Today a lady in our village died. She was in her late seventies but still very fit and active. Cause of death was electrocution. She was in her outside kitchen in which has an earth/soil floor damp from the recent rains. Using a plastic electric jug kettle to heat some water, she was in the habit of putting her fingers into the water to see if it was warm enough. Today that stupidity cost her life. There was a fault in the electric element that made the water live. Current passed from her fingers and through her bare feet to ground. There was undoubtedly no earth at the power outlet. As with nearly all village houses, there is no ELCB. A sad and totally avoidable incident which could so easily have been avoided with a little more knowledge of how a house should be wired.
  6. Very true. The average weight is more important. Even load distribution would indeed help keep fuel consumption down.
  7. Yep. That's what it's all about. Government subsidy = 4 million Cost of project = 3 million Projects department = Happy Happy Note to the nit-pickers. These numbers are not real but the idea probably is
  8. A few years ago just before Covid, I had sciatica. This is a compression of the sciatic nerve as it passes out of the spinal column between L4 and L5 of the lumbar region. The pain of this is very debilitating all down my right leg. There are two fixes for this. one involving a surgical procedure and the other, the simple exercise of walking or better still riding a bike. Walking for me was really too painful but riding my bike around the village for 6kM early every morning did the trick. It's not a quick fix by any means but it's free and healthy. The fix took about 6 months and many other bits of me started working much better. My doctor suggested I should use an exercise bike but quite honestly I find such things boring and less than adequate. Much more fun to ride around the village avoiding chickens, dogs, kids and angry old women.
  9. Good question. It's all so exciting isn't it.
  10. What filters do you have at the moment? 150ppm is very low. Is your well a bore hole?
  11. Non-contactable so couldn't receive the bill for the demolition.
  12. Note the electric flashing turn indicators and the windscreen wiper. The first ever electric one horsepower handsome cab.
  13. Here's another one for the connoisseurs. Ffestiniog Railway North Wales The line was constructed between 1833 and 1836 to transport slate from the quarries around the inland town of Blaenau Ffestiniog to the coastal town of Porthmadog where it was loaded onto ships. The railway was graded so that loaded wagons could be run by gravity downhill all the way from Blaenau Ffestiniog to the port. The empty wagons were hauled back up by horses, which travelled down in special 'dandy' wagons. To achieve this continuous grade (about 1 in 80 for much of the way), the line followed natural contours and employed cuttings and embankments built of stone and slate blocks without mortar. Prior to the completion in 1842 of a long tunnel through a spur in the Moelwyn Mountain, the slate trains were worked over the top via inclines (designed by Robert Stephenson), the site of which can still be seen although there are few visible remnants. Thanks to wiki for the description.
  14. Apologies if you didn't notice it, but my picture was a lead acid battery powered milk float not a golf cart. Yeah I've heard about the golf cart fires too. This is one of the reasons why I use lead carbon batteries for my solar ESS.
  15. I wonder how much oil an ICE engine on a dumper truck that size would need every oil change? Electric motors probably need a bit less.....????
  16. I won't happen to my EV......... There. Done.
  17. Nice observation but where did that initial energy come from? And is that energy being released when the rocks are rolled down the hill in order to charge batteries? And if the world was flat, what then?
  18. Yup. Agreed but something like it has been done a few times before. https://en.wikipedia.org/wiki/Gravity_battery
  19. That is one scenario which will undoubtedly work providing the mountain quarry is high enough to allow time for regen. braking to do it's stuff. What about another scenario where the quarry is lower than the road which is relatively flat? Not very versatile but good for elevated quarries in Switzerland.
  20. It's a You Tube vid. which for me = 90% BS.* However convincing the argument may seem, it matters not.............it's still You Tube. * The other 10% is brilliant but can be hard to find.
  21. I thought hazardous jobs were age restricted to persons 18 and over.
  22. I used Keyvisa at the beginning of this year and all went well apart from the passing of Darren during the process. This caused a small problem for me which was quickly resolved. I'm in Buriram so using an agent is probably cheaper for me. The process took 12 weeks.
