I'd go with the air filter change idea. When the mixture (petrol/air) is a bit weak, the engine runs hotter and may smell hot (something burning) and of course the engine won't have the power it normally has and will readily stall.

"They" don't make these large roundabouts because Thai drivers don't understand how they work.

Not just important files. You can share Youtube videos the same way if you're so inclined.

That's a question akin to how long is a piece of string. Generally I tend to go round corners on the assumption that someone has built a wall out of sight across the road and I need to be doing a speed that I can stop quickly without losing control.

Unmarked roadworks. 01:30 in the morning. Motor cyclist 16 years old. Car driver lost control possibly going way too fast and trying to avoid road works. Plenty of things to go wrong.

Yes I'm not surprised. There are cooling kits on the market which, as well as cooling the panels will also supply hot water. These come as a sort of copper pipe looped backward and forwards in contact with the rear of the panel. Another trick is to sprinkle the panels with water all day and recirculate it with a gutter arrangement but with this the water needs to be kept free of dirt and minerals which could stain the panels and thus reduce the light hitting the solar cells.

Not really a problem with solar. The heat is not caused by the panels so much as the sun shining on them. Panels mounted over water have much of that heat removed by the cooler water. This makes the panels more efficient but I suspect you know all this basic stuff already.

Nice ad. for the Moto GP circuit but the topic is F1 not Moto GP. The Buriram circuit is very compact and totally unsuitable for F1. It would take a huge amount of money to bring it up to F1 standard. I think Chid Chob would love to upgrade it but he 'aint got that sort of cash to gamble.

From the air, Suvarnabhumi airport looks like a couple of copulating caterpillars.

Ahaa. The wifey. That's a heat source I hadn't considered. You could be quite reasonably consider a 3MW inverter A/C for that I expect. Any further talk of your 'figs' and I will be tempted to report you.

There are a number of heat sources in solar power production some of which don't care if the ambient temperature goes up a bit (within reason). There is no point to waste A/C power trying to keep inverters etc. at 25ºC. It would be more energy efficient to enclose just the batteries and control the temperature of that enclosure. That figure of 25ºC is an older standard, particularly important for lead acid batteries, which can be increased to 30ºC for LiFePO4's and Lead Carbon batteries. Added to that I have long been advocating to charge batteries to less than 100%. It is far less stressful on the chemistry and will prolong the battery's life if it is only charged to (say) 95%.

These regulations are very flexible depending on a persons wealth and nothing else.

Agreed Plus Make it ilegal for a non-qualified person to undertake any electrical work.

If Trump comes across as "quite Barmy", what does that say about the millions who voted for him? I used to think of America as the land of high tech and cutting edge innovation and, above all, well educated and reasonably intelligent people. Clearly my thinking is in need of adjustment.

Teacher can only live in welfare accommodation? Salary must be crap. No wonder there is so much corruption

Why don't you fit an ATS?

Yeah. PEA are not happy for their customers to become their suppliers. There is some reluctance to give money back to the people they normally take it from. As for fitting batteries, if you are grid connected with a feed-in contract, PEA then becomes your battery. I haven't done any sums, but my guess is batteries would work out more expensive in the long run. That PEA limit on feed-in power would be the show stopper for me. Limiting my solar output to suit PEA is a big NO. Also I would be less than content to give right of entry to any bean counters. The problems of supplying power are a bit complex because of maintaining grid stability. In Australia, one would need to fit an inverter which can be controlled by the electricity company. This would allow them to control grid voltage by changing the outputs of hundreds of feed-in inverters. I prefer the simple life of my own, more or less, independent power.

What provider? I would think that PEA would have no knowledge of your battery installation 'til you tell 'em. Even so, I can't imagine why PEA would be interested in what your power source was be it batteries or solar. In my opinion and for what it's worth, I think It would be pretty daft to drain your batteries and wear 'em out for the sake of a few baht of feedback tarif. I have been off grid since the beginning of time which, for some believers, was 10,000 years ago but for me, was a massive 12 years ago. Mind you I still enjoy a few Amps from time to time from those wonderful fossil fueled PEA generators. I have a mini rice mill which will run quite happily on solar but for the stall current. That happens a few tymes per day. I'm still on the learning curve.

It is misleading to use the kWh of your electricity bill to estimate the power output of your inverter. For example: Shower heater at 4kW will use 18A @ 220v lets say for 5 minutes or 1/12th of an hour. That's 333Wh. But you would still need to have an inverter with enough power to deliver 18A or 4kW for 5 minutes.

Sizing is easy to do for yourself. Think about what appliances might all be on at the same time. Have a look at the rating plate on each of those appliances* The power for each is added plus 20% for future expansion. That will be a guide to the size of the inverter(s) you will need * The rating plate is a small usually rectangular metal plate attached to the appliance often on the back or side where you can't quite see it. Information on this plate will be voltage, frequency and power in watts. That power in watts is the relevant number you want. Example I worked out that I should have a 12kW inverter but in reality 8kW is more than enough. Incidentally I use 36kWh battery pack which discharges down to about 70% each night. I am completely off grid but have an ATS (Automatic Transfer Switch) so that I can use PEA electrickery, which just happens to come into my house, if necessary.

I don't understand this university thing in Thailand. Where I come from, universities are for much higher education than training for a technicians job. A technical college would be used to train an aircraft mechanic. A university would be used to train an aircraft designer.

Many thanks. His name reminded me of the Kama Sutra (the book of love pleasures) Yeah! If I remember correctly he was grossly overweight so prison may have done him some good. Same could not be said about skinny old Taksin.

There was that Ital-Thai guy some years ago jailed for poaching. He was wealthy, but you're right. I can't remember his name.

He's not too rich to be jailed, but he has supporters in extremely high places who control what happens with or without legal shenanigans.

I have come across these horrendously complex contractual rules in the UK in the past. The primary customer/project owner will only make stage completion payments which could be months if not years down the line. These stage payments are further delayed simply because the primary customer/project owner doesn't want to pay too much interest on the loan needed to finance the project. It is the sub contractors contractual responsibility to have sufficient funds to complete the contract. Also these types of contracts are designed to make it difficult if not impossible to seek redress ie "If you don't like it you must go to Singapore and argue your point in a court using laws of a foreign country". I got caught by this once in the UK but fortunately I was not contractually obliged to remain working for nothing. I walked away from that job after some weeks of non payment.
