I finally got round to do some analysis on the small 5W and 8W solar panels I have been using for tendering car batteries. The conclusions is they are more or less useless. Unless facing the sun directly, the power output drops to next to nothing. At mid-day, with the sun at an angle to the...

Yes. But those things were sorted and there were no more worries. No need to talk about oil when I am on life time oil. No need to talk about jacking when the mot guy said my car was perfect in Dec, etc.

I said nothing about those things for a long time, though.

But, you do. You keep talking about it. That shows the potential risks are keeping you awake at night. I would just get rid of them and live in peace.

Not something I have to worry about. Once it goes off, the insurance will find ways to "uncover" it. But, life is a gamble, eh?

Some of it went into my bucket after scrubbing. Some of it probably rained down on your large lawn.

After cleaning up, the filler neck looks to be in fair condition. There are spots of roughness on the fill neck funnel where the cap gasket presses against. This will likely to prevent a perfect seal. For now, I will just keep it under observation. Failing of MOT is unlikely even if the tester...

For someone with very poor feel for things, let AI help you: AI Overview Learn more Lithium can spontaneously ignite in air if it's finely divided into a powder or dust. It can also ignite if it's heated to 180°C. The autoignition temperature of jet fuel is 210°C (410°F). The autoignition...

If AI doesn't meet your requirements, perhaps youtube will?

How do you know there is a hole? I can't tell if there is a hole. If they look under the car, no need for me to do it then.

Wrong. AI Overview Learn more Yes, jet fuel is considered volatile, meaning it readily evaporates into vapor, especially when compared to other fuels like diesel, but not as volatile as gasoline; however, compared to other aviation fuels, its volatility varies depending on the specific type...

My guess is your tractor is special. Is it a toy one? All other tractors are diesel. I believe diesel is "heavier" and evaporates differently to petrol. An extremely refined fuel used by planes will go gaseous even faster. Liquid rocket fuel goes gaseous faster still. Faster the burn required...

Someone quoted a US study that proves you wrong.

Not really. The evap system didn't do a single thing for 6 months or more. The built up evaporation jetted out the cap continuously for the same period. Petrol is gaseous in typical environmental conditions, unless pressurised, or frozen.

So, you are none the wiser if I didn't tell you about it. I was assuming you were answering whether an air leak was an MOT fail. But you appear not. The gist of it is I have a pass, unless I tell the tester I have an air leak. Car body shell is in way of the petrol fume "rain". There is nothing...

Hydrogen is a liquid too if given enough pressure.

The information on this china cap reveals various characteristics of the fuel tank, which is likely to be universal. The inner side appears to have some kind of air pressure handling mechanism. Although it could just be part of the clicker device.

Under the designed tank pressure. I think the micra filler cap is designed to release pressure if too high.

No. I have been studying petrol evaporation recently, and how it made the car paint dirty.

How do you know the seal is lacking? The leak is at the top. Why would I clean the bottom?
