I always remember my geography teacher saying sometime in the early 1970's, only the very rich and very poor have large families. The rich because they can afford it and the poor because they know no better. The 'middle classes' often make decisions on the change it will bring to lifestyle affording to bring up more than one or two children. Maybe the statistics are what really led to the changes in USA abortion laws and not the 'religious majority'?

@sswpp8908 I believe the auto industry is using less than 10% of the platinum it was when catalytic converters were first being used. If it's accessible, it will just as easily be stolen, in fact even more likely if the price goes up

I haven't studied psychology for a long time but last job I had used 'personality' tests too frequently, (at least once a year) The relevant questions were very obvious to me so I gave them false answers (just because I could) then told the people running the S***show later towards the end of whatever course we were being primed on. (Corporate America, must have loyalty to the company while they screw you over) Usual reply was 'You can't do that' My reply was always 'I just did' 🤣 If the company had used the same people every year it would have become obvious to them I had MAJOR personality disorder as the results varied so much, but, it took major downturn before I got laid off 12 years after starting there (along with several hundred other people)

I always wondered about jet exhaust, it can't be good when your deliberately putting particulate in the atmosphere at 30¬80,000 feet

I worked on construction equipment in the 1990's when PSP10 (10 micron particulates) was a 'BIG ISSUE' but almost totally ignored by companies who didn't need inspection for non road going equipment. It's always bothered me that the true cost of 'electric vehicles' is skated over. Just one large mining truck will burn through around 1,000 US gallons (~4,000 litres of diesel a day. The important thing is to keep them running as efficiently as possible but majority of mechanics will 'mess' with things to attempt to get more power (and a load of soot) Often drivers get paid 'by the load' and managers get ordered by 'higher up's' to increase production, Diesels work most efficiently with excess air, black 'smoke' means too much fuel but rarely a lot more power (soot in exhaust being burned usually results is a brownish grey smoke) As you said, there is a lot of misinformation and even worse, in my opinion, ignored and hidden facts

Any half intelligent British person who grew up in the 60's~70's could predict the 2008 crash. I was almost fired for telling people I worked with it was coming and I was a motorcycle mechanic. (I did get laid off 2011) You didn't need a PHD to see the writing on the wall.

@EngineeringNibbles I recently found out about a tyre wear particulate study in UK.(even a very quick internet search will find it) Seems EV's are really bad at 2.5 micron level as the battery packs make them heavy causing higher tyre wear, carbon and silicates are used in tyres

I think the problem is 'never let the truth get in the way of a good story' It's alos pretty obvious that researchers are justifiably afraid of loosing research funding, which many of them justifiably deserve for perpetuating the myth that they are 'almost there.I think it was Lindybeige who did an interesting piece on the major differences between British and German production methods during WWII. Simplified version - British had centralised oversight but Germany wanted intense competition between manufacturers which led to duplication and a waste of resources. If some sort of centralised oversight on fusion was in place, research may actually go faster? (or at least the same experiments wouldn't keep being duplicated?)

I'm glad you at least mentioned coal produces radioactive 'waste' For the last 45 (probably more) years I've been asking about 'fall out' from coal fired power stations and never got any answers. (to me, it seemed logical that if coal has radioactive Carbon 14, it probably also has other radioactive elements) I wondered as even a very low background level would be concentrated when millions of tons of coal are burned at one place About 2~3 years ago I asked again in the comments section on a Thorium reactor video. At the time I was told that if I found out anything it would probably be better to stay quiet as the 'industry' wouldn't want it to be common knowledge. I did get a reply from a guy who was doing his thesis in the late 1970's who actually did monitor elevated radiation around coal powered power plants. I forget the details but it has been known about for decades but is 'hidden' and very difficult to find real information (knowing the right questions?) The other thing, wind power isn't really very 'green' It isn't just the production of the parts, the blades 'wear out' pretty fast plus kill tens of thousands of birds and displace a lot of wildlife due to the land clearing, etc. Thorium appears to be much safer even if more expensive at present, the engineering challenges can be overcome if there is a will to do so Long term, everything I've found out about Thorium reactors seems to be a plus as it can use the waste from conventional nuclear plants as fuel making nuclear proliferation far more difficult when Plutonium is being converted to something 'safer' rather than being stockpiled to make 'dirty' bombs. Sorry for the long post but I think this could warrant a couple more video's?

@gviehmann I've only ever had one response from someone who was doing (I think) higher level degree in California when plans were being proposed for a new coal or nuclear power station. He found much higher radiation levels at coal fired power stations but they were classed as 'natural' and ignored. When thousands of tons of coal are being burned in one place, even 'trace amounts' can end up being quite substantial. Your not connected with the coal mining industry are you?

Your reading the wrong magazines and newspapers plus not using much common sense' (critical thinking?) Majority of articles I read in the past, somewhere buried was the actual power in vs. power out and the math never adde3d up to the headline

I studied psychology for several years ( but only managed one year at degree level - it was quite difficult to study when working 12 or more hours a day) The EPI tests (Eysenck's Personality Inventory) was probably a better explanation as knowing about it (even though some of his results were 'falsified' ) made it quite easy to give the Myers -Briggs people whatever results you wanted them to have even though the tests have been 'refined' over several decades. Being in America means they refuse to use tests 'invented' by a German born Brit In a hundred + questions, generally, as few as 8 or 10 are actually relevant to the result I only ever attended one of Eysenck's lectures, a few years before he died when he was experimenting with the benefits of psychology on cancer patients, probably led to the 'I know I can' revolution in sports psychology? If you want to change your personality to be more extrovert, you can, but it isn't easy or short term job, you can learn and practice until it becomes 'normal'

Pretty sure someone has already said it with almost 12,000 comments, took you a while to realise it's how the rest of us 'in the real world' get shit on by managers.

For some reason, I always understood that hydrogen production without nuclear power was a non starter, it took more energy to creat the hydrogen than you got back I think it may have been my geography teacher in 1972 (or 73?) He was a real smart guy and had a lot of interests outside of just teaching geography (I do remember him being very, very disparaging about 'American' pressurised water reactors believing them unsafe well before Three Mile Island (built too fast and too cheap by lowest bidder)

I'm Welsh living in 'murrica' since 1998. Native New Yorkers don't call it New York but N'Yok Some of the US spellings really are awful without context. Two things that have always 'bugged' me, no zero before a decimal point (.1 and not 0.1 way too easy to overlook the decimal) and check, you have no idea what check? ' The check was not checked' doesn't make a lot of sense but 'The cheque was not checked' is obviously something to do with banking and not a 'tick box' I tell people I only speak two languages, British English and American English
