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.....????

I won't happen to my EV......... There. Done.

Stop looking it's not good for you.

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?

Yup. Agreed but something like it has been done a few times before. https://en.wikipedia.org/wiki/Gravity_battery

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.

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.

I thought hazardous jobs were age restricted to persons 18 and over.

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.

I once asked someone if they could tell where I come from with my English accent. They told me I was cosmopolitan. I looked on Google maps but couldn't find it anywhere.

Yeah. It's about time he started giving some of his money back to the people he took it from.

I thought that was a picture of a small village lake. Strange the local kamnan should pass up an opportunity to make a few bob. Possible reason could be govt. money not forthcoming.

maybe some a lot of plastic surgery

Agreed but................. Could be done with a dropper resistor and zener plus all the usual ac-dc bits.

Agreed. I would be looking for something like "internally protected" in the sales blurb and/or the specs.

Brilliant. That CE mark says it all plus the other glyphs. I can safely say that with those conformancy markings that device should not catch fire. Also in the tear down section of the video, I think I caught sight of a pcb mounted fuse. It is double insulated according to the triangle with the circle and tick mark inside. So from the viewpoint of electric shock safety everything is fine. With regards to isolation, what I was referring to is the internal circuitry between AC mains and low voltage DC supply for the processor etc.

I just had a look at the video of the similar looking "Shelly" device and notice there are a number of things missing in the writing on the front of the unit of the OP device. Chinese Copy?

I wouldn't rely on that unless it actually had words to that effect in the spec. That unit seems vey small to have any isolation between AC and processor. Does it have any conformancy spec numbers on the back like UL for example?

Tact and diplomacy are always better when talking about someones girlfriend. Generally in short supply when pi$$ed

OK so the in-line fuse is the right way to go and the fuse needs to be rated for the current of the light plus background power of the Wi-Fi switch. I am personally content to hike over to the switch to operate it or better still get my missus to do it. ????

Really?

I would fit one of these in-line fuses in the live wire. https://shopee.co.th/กระบอกฟิวส์-5x20-mm-ใส่ฟิวส์หลอดแก้ว-In-Line-fuse-holder-i.561759750.18751433394?sp_atk=114860b4-86b4-4e45-a220-9da377b67d84&xptdk=114860b4-86b4-4e45-a220-9da377b67d84 There is a possible fire hazard in the "Shelly" (what's that?) if an internal component should fail. Does the "Shelly" have any internal protection?

Insulation generally will absolutely reduce heat entering the house in Thailand and, of course, reduce heat loss in a cold country. The ceiling loft space is responsible for something like 25% of energy loss. The more insulation used the better but watch out for something called diminishing returns. PE Foam is probably quite good although I prefer and have installed the quilted fiberglass. The result is what it's all about. My thinking is that there is more air in the 6" thick fiberglass so it should be a better insulator. Also the aluminium foil keeps that air from moving and stops the weight of dust from eventually collapsing the fiberglass. It is a case of personal preference which to choose I think. I found this helpful site which you might like to look at. https://www.greenbuildingadvisor.com/green-basics/insulation-overview-2#:~:text=ABOUT INSULATION&text=The thermal barrier of a,cutting heat loss in half. "Doubling the thickness of insulation will double the insulation’s R-value, cutting heat loss in half. Each time the insulation layer is doubled in thickness, this rule applies. The energy saved per year by doubling insulation from R-10 to R-20, however, will be considerably more than the energy saved by doubling insulation from R-20 to R-40, because of the law of diminishing returns. In some cases, like an attic, it’s worth piling on more insulation because there is plenty of room. It’s much more expensive to add that much insulation to exterior walls."

Thanks to all for improving my understanding of the word "morbid".
