content: Full disclaimer! I do not smoke, neither I do encourage anybody to smoke. Smoking is unhealthy!Locally it's common place to find discarded disposable electronic cigarettes (DEC). Usually in public trash bins. Together with old-fashioned cigarette buds.These days in western civilisation ecology is the hottest topic. With every major business virtues signalling how much it cares about ecology (carbon neutrality and such). When we have this thing - DEC. Take a look at the attached image. That's how a typical DEC looks like disassembled.Compared to the classic cigarette, it most certainly doesn't scream ecology (not that classic cigarettes are eco friendly, but still) . And yet these things are discarded left, right and centre into common garbage bins.Hypocrisy in its finest!

content: I used to smoke regular cigarettes and knew it was bad for the planet because of all the litter. That's one reason I switched to vaping. It made me feel better health-wise, and I thought it was a bit better for the environment too.I've noticed more people around me vaping instead of smoking, which seems to reduce the litter from cigarette butts. But there's still a problem with throwing away used vapes. For over five years, I've been usingLostmary Vapes, and it's been good for me. I like thinking I'm doing something a little better for the earth. Plus, vaping has helped my health, and it's nice to see others choosing it too, hopefully making things a bit cleaner.

A lazy smoker discarding cigarette butts onto the ground, is no different to a lazy vaper discarding disposable vapes into the regular trash.

In Australia, our cigarette smokers drop their butts onto the ground, which makes its way into storm water drains and waterways, eventually washing back up on the beach, or eaten by wildlife. And sometimes the non-extinguished butts are thrown into dry grassland, igniting bushfires.Either way, discarded butt waste is the bane of ecological damage.

So you need to make sure it is charged and used maybe half a dozen times to break even. Then there is the safety aspect.

content: Trouble with the disposable society we are in now...From E-Cig to dish washer to refrigerator to even cars. Everything is made to be throw away after a short life. With the advancement in manufacturing technologies, making a new one is cheap. Keeping it going is too expensive. Disposable E-Cig is guilty but hardly alone. Average minds have been conditioned to expect things not to be durable.Looking at present day appliances, so many of them are tied to Apps, which has life expectancy tied to the phone's version, the battery, the manufacturer being around, the ability of Google/Apple supporting certain outdated function, so on, so on... whichever is shortest.Less than a week ago (Feb 22), AT&T has a nation wide network 11 hours long outage/disruption. I suppose some would have been unable to unlock their front door; some might have been hungry because they can't order their lunch or dinner; some might have been wondering for 11 hours how dirty his/her clothing must be since the phone still hasn't told them their wash is done...I recalled years ago in the office, we used to joke about "can you imagine needing to reboot your coffee maker?" Now it is reality.May be someday and hopefully someday soon, durability will come back in fashion rather than today's domination of modernity of design.

I've been using, temporarily, the known common-term, 'Dumb Ass', privately, to connotate a truly smart person or trend, that fails in some common sense level.Doctors that don't have the social exposure that teaches that all street drugs NOT same, regardless of truly scientifically established 'overdose' and fatality numbers. Or watched any of the riveting 'Breaking Bad' episodes....Dumb+Ass in waste and toxics professions might mean overemphasis on small, apparent waste issues, meanwhile ignoring the large but similar content, like plastic milk and water / beverage containers.One of my pet peeves, is how some municipalities can, like, re-consolodate the separated trash routes, back into one big steaming pile, at the waste management site....or was that just a myth going around ?

content: Quote from: Rick Law on February 29, 2024, 01:45:41 amThe irony is that this scenario is not any kind of surprise. E.M. Forster wrote "The Machine Stops" over a hundred years ago.The reason it is inevitable is because the logic of short-term profit (known asfinance capitalismorfinancialization) does not allow any room for durability or resiliency as goals. When things work, the profits are privatized through asset management firms. When they break down, the losses are socialized and bailed out by the taxpayers. The only way out is for a collapse of the entire economic system, which today does not look that far off.

But even so, companies will easily find ways to circumvent that and send the waste to countries that are not in the list, as the article itself says.One huge source of plastic waste is not McDonald's straws, it's plastic bottles for water and soda. And I still don't see these banned anywhere.And yes, oceans are now pumped full of microplastics that you find inside fishes. That's yummy. Would you like some pink rice right from the lab to go with your plastic fish?

content: I'm not for banning that altogether, it never works and can only favor trafficking and make things even worse.One good step, I agree, would be to ban a number of specific chemicals that are used in most industrial cigarettes, and known to cause various problems. That is not "banning tobacco", would do absolutely nothing to favor trafficking (no customer will want an illegal product just because it contains nasty chemicals that provide no benefit to them, not even getting them high.)Heck, we could even ban cigarettes, but not tobacco (as in the old days before industrial cigarettes became mainstream.) That would drastically reduce the number of smokers while not being a complete ban.Same for food indeed.But even that is dubious - as you mentioned, taxes that are raised from it all are so huge that no state can really afford to do without them.If it loses 10 billions a year, that's 10 billions that people will have to pay another way, and all of them, not just those who chose to smoke.Health costs resulting from that are much lower, as some have pointed out, and even so, the effect on health costs would be seen only maybe a full generation later. Not that it's a good reason for not doing it, but just mentioning that for a generation, people will HAVE to pay a lot more in other taxes to compensate.

There's already a sugar tax on soft drinks over a certain percentage of sugar, but the manufactures simply replaced some of the sugar with artificial sweeteners, which aren't proven to be any more healthy or result in weight loss. Food is already processed enough. I doubt anyone wants it to become more artificial to circumvent taxes.The driving test is already difficult enough as it is. There's a computer based simulator and written exam as well as the practical test. A big weakness is, foreigners from countries with less stringent driving tests can come here and drive on an international license, but I doubt the government will stop that.

content: Back on the whole "disposable vs. make it last" question: One aspect often forgotten is the rapid pace of tech advancement. There's no point in making something better, or more repairable, or longer lasting if it's rendered obsolete quickly.Example: The media almost daily reports how unhappy the greenies are that existing ICE cars are so reliable and last so long, because they see that as delaying their complete replacement by EV's. With that kind of mindset, short-term thinking and throw-away mentality is a unavoidable.If the state of the art in PC's or cellphones radically improves in 12-24 months, what motivation is there to keep old equipment running? Yes, this argument doesn't apply to all products but it does to a very large segment of the commercial economy.

ASH (Action on Smoking and Health) are an anti-tobacco charity, so it's in their interests to cite information which makes smoking look as bad as possible.It's very difficult to come to an exact figure regarding the costs of something like tobacco. This isn't helped by the fact that people will cherry pick data and bias studies to suite their point of view.Banning tobacco will also be costly. It will become an illicit drug, which means criminal organisations will fill the void, left by legal manufactures and retailers.I don't smoke myself, but am biased towards libertarianism and as fewer laws as possible.

The next gen will probably be much more "environmentally friendly" in isolation, for instance the batteries, and that will trigger the replacement of the whole EV park in the same way. That's unreasonable.The solution to this is quite simple though: do the maths, and do them honestly. Check what is worse, over the lifetime of the vehicles, between keeping a vehicle that runs perfectly fine but is a bit more polluting, vs. one that is less polluting but will have to be manufactured from scratch, and the associated cost of dismantling the old ones.In other words, our decisions should be rational and, as much as possible, without any conflict of interest.TLDR; it won't happen.

content: Quote from: NiHaoMike on March 28, 2024, 12:41:56 pmGreat. More laws.The problem is there isn't a scientific consensus on what's harmful and what isn't. For example aspartame is generally considered safe. It might be carcinogenic in large quantities, but the same is true for other chemicals which are present in food, or develop during cooking.Quite often it's the food as a whole which is healthy or not so healthy, rather than the individual ingredients. For example, whole oranges are high in sugar, yet don't result in the same sugar spikes as orange juice, which is similar to a fizzy drink. What law can deal with that?Quote from: Andy Chee on March 30, 2024, 02:45:27 pmThe same is true of other vices such as alcohol.Quote from: NiHaoMike on March 31, 2024, 03:42:41 amThat's not true. A much lighter, energy dense battery would greatly increase the efficiency, as well as causing less air pollution from brake and rubber dust.

content: Quote from: NiHaoMike on March 31, 2024, 03:42:41 amSolid state lithium batteries will be half the size (and safer). Axial Flux motors can save several kilograms of copper windings. Charging losses can be greatly reduced if the car manufacturers would spend a little more effort on software, because the charger itself is efficient but the car wastes a bunch of energy needlessly running everything else.

content: Quote from: NiHaoMike on March 31, 2024, 03:42:41 amFar from it, and and it's not just about raw efficiency either: I explicitely mentioned the batteries, which currently still suck and are certainly not the end of the story.But even the rest is far from having ideal efficiency if you look closely at the whole chain.Again, my point is: do the maths, don't act with emotion and beliefs.

content: Quote from: SiliconWizard on March 31, 2024, 09:06:42 pmAren't EVs something like 80-90% efficient, as opposed to state of the art gas engines that top out around 40% before considering other losses? I'm sure a lot can be improved on the resources needed to manufacture a new car, but that's irrelevant for a car that's already been in use for many years.

content: Quote from: NiHaoMike on April 02, 2024, 02:41:51 amOf course not. That's about the efficiency of its main parts separately, as AVGresponding just said above, but of course not the whole chain as I said.Just start with a very optimistic: 90% for the electric motors, 90% for the power electronics driving these, 90% for the batteries themselves (which is probably very optimistic once they get hot), and another 90% for the charging. That's just 66%, accounting only for the main parts, and probably already very optimistic (real figures under real conditions may well be down to around 50-60%). Still significantly better that ICE for sure, but not that dramatically.

content: Quote from: SiliconWizard on April 02, 2024, 05:50:21 amORNL tested the 2012 Leaf motor and inverter at greater than 90% over most of its operating range.https://www.energy.gov/sites/default/files/2014/03/f13/ape006_burress_2013_o.pdfThe efficiency of the battery itself wasn't mentioned in that PDF but a similar one is listed at 96% round trip. The charger is easily 95% or better for an overall efficiency of greater than 82%.Quote from: AVGresponding on April 02, 2024, 05:19:29 amThe big improvements there would be aerodynamics and tires, which are already a big focus for EVs. One problem is that the higher efficiency tires are more expensive and wear out before the energy savings pay for themselves, particularly with EVs.

You shouldn't assume things, because you underestimate how bad software and cables can be.https://www-motor-no.translate.goog/elbil/dette-er-de-mest-og-minst-effektive-elbilene/199860?_x_tr_sl=nl&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wappFor example Renault Zoe: 52KWh pack, 54 KWh to charge it, ~81% efficiency.And all this discussion is off topic still.
