Pneumatic valve operation has been used in racing engines for years.
Current F1 engines have adopted a pre ignition setup which allows a more efficient combustion and a more complete burn. It's quite a smart idea.

Ooh... Design life, a fresh subject on its own. I work in the rail industry and the subject is prominent there. Historically a train was expected to have a 'life' of between 30-40 years(and have delivered that), It's pretty impressive. I live very close to the Cumbrian coast line, so see -and often just hear- a variety of DRS Class 37's running up anx down during the day. I'm not a train spotter by any means, but had enough interest to look up a couple of numbers, and raised an eyebrow at the discovery that they were all built in the 60's. Well impressed.

That's impressive on a few levels.
Mostly grades of stupidity, but impressive nonetheless.

I just did my research, seems the i8 isn't set up the way I thought it was.
What I had in mind was a small efficient engine running a generator to power an electric drive, rather than relying on batteries to provide the power.

Sorry but you don't understand. You may well be able to draw enough current from each post to charge one car but you won't be able to draw enough from every post in the street to charge all the cars in the street. (In my street i'd hazard a guess at 10 cars per lamp) ofcourse you won't find the company marketing these things making such a point will you ;-) One also needs to consider that street lamps are powered by current electricity network, which -having discussed this some with friends who work in power distribution- isn't really up to the job of supporting the demand that would be placed upon it if we all had electric cars. At present, I can see the best way forward being something like the BMW i8 driveline, a small generator powering electric motors If certainly say it has more mileage in it than some hybrid/energy recovery systems.

Where does one find the data plate on an elephant?
And what are it's axle weights?

I can't find the source, but I have also seen it said that the recent fashion to move back to wood burners and coal fires -especially in inner cities- is a much bigger contributor towards 'particulate emissions' than internal combustion.
Something else that is very loosely regulated at the moment.

With the diesel engine finding more opposition (in the UK at least) in recent months, along with a noticeable increase in the price at the pump I find myself pondering where the owners of diesel engined vehicles will find themselves in the next 12 months or more.
With this years budget just around the corner, one has to focus attention on the talk surrounding scrappage deals on older diesel vehicles, raising of vehicle excise rates on diesel vehicles, and even an increase in fuel duty, and wonder just how likely it is these threats will actually materialise.
There's lots of conflicting research to suggest that once again it's the motorist copping it as an easy target, and that there are lots of other -less easily regulated- sources of particulate emissions doing as much damage, along with plenty more to tell us all that anything other than an electric car is killing us.
Interestingly, I understand that the Australian Government has recently come up with a scheme to encourage motorists that diesel engines are a more environmentally friendly option.
The Government's willingness to make rapid U turns on other matters suggests that we may not see any sort of major revolution, but with what attention I do pay to politics, I'm certain enough in my view that I don't trust them not to try and do us over one way or another, especially if it helps out ministers business interests, or lines their friends pockets.
Or put another way, whilst we may not be about to see the death of Diesel, what are the odds that a lynch mob are going to jump out and give it a damn good shoeing?

A nice clear answer from DVSA which doesn't contradict anything else they've said at all...
With the number plate thing, it is my understanding that cars, wagons etc need to display the same plate as the towing vehicle, however with Agricultural trailers and impliments it is acceptable to have a differing plate provided the number belongs to a machine registered to the operators farm.
The contractor I work for has the number from an old 70's tractor that hasn't run on the road for 20 years or more (but is still active/registered as an agricultural vehicle with DVLA, whilst all the machines that tow them on the road are less than 10 years old.

Quite a common one with D20 Navaras at the moment. Engine in bits in the back and people are still paying £1000 for them. Madness!!! . I replied "OK, come and get her". A few hours later two cocky kids turned up, having driven 80 miles to my house. "Nah, just kidding, it's £2000" I told them. Did I feel guilty for wasting their time? Nope. Perhaps the funniest thing I've heard today, and something I'd love to fond myself in a position to try.

I have questioned companies in the past about why they charge so much extra for a modified car and they start on about dangerously modified Land Rovers. I think there was an accident that got a lot of media interest that started that. There was. Some sort of mechanical failure on a vehicle the guy maintained himself. I believe he rolled it into a lake with wife and their four or five children on board, and two or three of the kids died as a result. I also recall the investigation of the wreck found things such as mismatched callipers on the front axle and a variety of other mechanical maladies. He got a few years inside for it, but having seen the name popping up on a few Land Rover based Facebook groups in the past year or so I must assume he's out.

Currently stickers are my bugbear - modern chav cars like astras with flowing italic text stickers on the windows usually relating to something being low .That and Nurburgring stickers ! One accessory [ not really ] i miss is the old REDEX you used to get to pour down your carb and then floor , filling the road up with smoke ! +1 'Dirty diesel' and 'because [insert car here'. Those two irritate me the most. I'm not a big fan of stickers either. 'One Life. Live it.' being a fine example. There's quite a few Volkswagen Group vehicles round here with 'West Coast VAGs' stickers on them. I'm sure I'm not the only one who thinks 'bunch of fannys'. As for decent stuff, tow bars, and a decent set of mud flaps are both on the list, especially the brightly coloured Sparco ones. I've rediscovered my liking for 8 spoke wellers too. They have to be ice white with the red and blue pinstriping round the edge of the rim though.

Indeed. 'Case law' established after a dispute has gone to trial is quite different to a county judge dismissing a ticket.

I'm sure you'll find some clown who'll proudly announce that the repairs have been carried out with steel thicker than the original so therefore much stronger than the original.
Worthy of a slow shake of the head then walk away muttering about their mental capacity.

Had youngest daughter at the workshop with me earlier today, so got her to hold the camera and shoot a video of it on the move around the yard.

How else can they expect to fill column inches so completely on a weekly basis?

Navara's are horrible things whatever the spec, and wherever they were built.
That probably doesn't help you though.

"What's the best price mate ?? ...." Well - if I'm offering something for £500 - I'd love £600+ 👍🏽👍🏽. I always reply - the price I've iadvertised it at ! Strangely, they usually lose interest then ! I recently had a cheap one motor up for £500. Some tool just put £200 in his reply to the ad - nothing else ! Obviously I didn't even answer him (& sold said car a week later for full asking price). Not a fan of that either. I recently sold a Land Rover advertised at £1200 ono (Or Near Offer obviously) and wasn't really surprised how many silly responses I got. Within half an hour I had received a message simply stating '500 for jeep pal' which was unsurprisingly ignored, whilst others were at me thinking £700-800 was also a 'near offer'. Again it sold to a lad who paid the asking price without cocking about, and has since been in contact to tell me how pleased he is with the thing. Another good one I've seen recently on Facebook buy/sell/swop groups was in response to an Isuzu Trooper advertised at £700. Some wag popped up offering £350 Cash, to which the seller responded 'No Problem, and how will you be paying the rest?'. Classic.
