Many automatics these days are manual transmissions with a computer controlling the clutch. They have nothing in common with the slushboxes of old, the oil is just for lubrication.

ZF 8HP is still a traditional torque converter transmission. Most high performance or high torque applications use that design. Dual clutch automatics or automated manuals can't take it.

Tremec makes DCTs that are used in 800hp Mustangs and 1000hp Corvettes

Virtually every truck has an automated manual transmission, every EV 2-speed is a DCT, Porsche uses PDKs etc.

Every truck? Like which ones?

As an American (land of the pickup truck) I can't think of any

I think GP meant eighteen-wheelers and the like.

More like SUVs with beds

But yes, sibling is correct, I'm talking about commercial vehicles.

Citation needed. By truck if you mean commercial truck (lorry, artic, etc.) then no, Allison still makes hydraulic automatics which are very common in vocational work the world over.

Even slushboxes tend to aggressively lock up the torque converter. It's usually only in a "fluid dynamics" mode for brief moments. (Except maybe on a gentle hill start)

Maybe in sports cars but the majority of vehicles still come with hydraulic autos or CVTs.

I mean, certainly the VAG group likes to use their dual clutch automatics, but "true" torque converters are still very common. ZF makes them for like a million different cars, and AISIN makes them for the Volvo and Geely group.

As what efficency? The artical doesn't say, but hydraulics and automatic transmissions have been around for a long time and are less efficient than regular gears or electric motors. Cars got a good efficieny boost then the locking torque converter was developed.

I kept my last car for almost 20 years for that reason, but parts were rusting off - the fuel tank fell off was what made me give up. At this point that car is scrap and I am in a newer car that is made no matter what, so that co2 is a given.

This is about transportation. Walking doesn't get you far. A bike uses similear energy but you get farther.

Walking covers most of my journeys for which a bike would work. I am not going to bike a hundred mile, or even 15 and back. Nor is it practical to bike to the supermarket. On the other hand its easy to walk a few minutes to the local shops and pubs.

Transportation and exercise are linked. Walking kills two birds with one stone.

New cars are typically on a 3 year lease - a lot of people must be keeping cars for a long time to bring the average to 7

Flea markets were always this way. Even in the 1970s, probaply before but I'm not old enough to know people who did it.

That is the stated lifetime - but they typically last much longer.

The problem with outside vents is sometimes smoke goes out them - air comes down the chimney.

This isn't a good idea because the water cools the fire too fast and you tend to get soot build up inside.

Modern insulation with hvac is better yet. You need hvac to bring air in as a modern house should be air tight. Not much heat or ac should be needed.

I’m inclined to agree, even in cold places. AC is remarkably efficient, especially when you reverse it (and get a heat pump).

…but when electricity dies down, you’re basically fucked.

My main source of heating is a gas boiler, but it requires two pumps to actually push the water around. If our power is out we have no heating.
