I didn't spot the thermal efficiency in the Wikipedia article so I did some more digging. Apparently the engine is over 50% thermally efficient - i.e. more than half of the energy in the fuel is converted into motion. And a further 12% can be recovered from the exhaust heat (being used for electrical generation). So in theory it could extract nearly two thirds of the energy from the fuel into useful work. Bloody impressive.

https://en.wikipedia.org/wiki/Straight-fourteen_engine

The only straight-14 engine known to reach production is part of the Wärtsilä-Sulzer RTA96-C family of 6-cylinder to 14-cylinder two-stroke marine engines. This engine is used in the Emma Mærsk, which was the world's largest container ship when it was built in 2006. The engine produces 80,080 kW (107,390 hp) and displaces 25,340 L (1,546,342 in3), has a bore of 960 mm (38 in) and a stroke of 2,500 mm (98 in). The engine is 27.3 metres (90 ft) long, 13.5 m (44 ft) high and weighs 2,300 t (2,535 short tons).

My wife says I'm not allowed one. I'll leave this one to Dave! 8-)
Have you tried explaining how well it can tow... Anything?

Not sure if this has been posted here before

An American wine connoisseur made the mistake of reviewing buckfast… Here’s their tasting notes:

Buckfast Tonic Wine (No Vintage)

Screw cap, took it off about 30 minutes before to bring in some air. Apparently made by monks in England. Decided to try while cooking dinner. Poured into a glass, first glance has a very inky almost brownish color that you see in older wines. Very syrupy, liquid clings to the side of the glass when swirled. Almost 15% ABV.

Stuck my nose in and was hit with something I’ve never experienced before. Barnyardy funk (in a bad way) almost like a dead animal in a bird’s nest. A mix of flat Coca Cola and caramel with a whiff of gun metal.

On the palate, overwhelming sweetness and sugar. Cherry Cola mixed with Benadryl. Unlike anything I’ve tasted. I’m not sure what this liquid is but it is not wine, I’m actually not sure what it is but it tastes like something a doctor would prescribe. A chemical concoction of the highest degree. Can only compare it to a Four Loko.

Managed to make it through a couple small glasses but not much more. Has absolutely ruined the evening drinking-wise for me as I tried to drink a nice Bordeaux after but the iron-like metallic sweet aftertaste I just couldn’t get out of my mouth even after a few glasses of water. I don’t drink a lot of coffee regularly so I also have mild heart palpitations from the caffeine after just drinking a bit of this and feel a slight migraine.

An ungodly concoction made by seemingly godly men. I believe the Vatican needs to send an exorcist over to Buckfast Abbey as the devil’s works are cleary present there. After tasting this “wine,” the way I feel can only be described as akin to being under a bridge on one’s knees orally pleasing a vagrant while simultaneously drinking liquified meth through a dirty rag.

I’ve drank a lot of wines in my life and will never forget this one.

That's a full bottle of 'fuck yes!' 8-)

Think how much cooler it would be without PDK though... It does also remind me of the trip I did to the 'ring before I left Europe in 2007 (with Nebpor, Balmer, Patrick, Andys 1 and 2 of this former shire) where we were watching some of the pre-production cars hooning around. A GT2 RS (from memory) sounded both similar to this and very different - the sound was obviously turbo but hung on the trees and was audible for what we estimated/timed was probably half the lap. Even the LFA didn't hang on quite as long.

We are comfortably over 90% in our greenhouse engines. If we can increase the load a bit we can improve still.

CO2 from exhaust for plants, electrical load is 48% efficient by itself. High temperature, low temperature and oil system is used to regulate the greenhouse temperature.
