Trying to protect people from every conceivable form of self-harm at the government level is evil. Progress is made by every person being a small experiment of what works and what doesn't, and that produces winners and losers. Restrict liberty too much, and we're all just losers. I'd rather live in a world of winners and losers where the losers still aren't miserable, rather than live in a world where everyone is a miserable loser. Balance is key.



OK, what's preventing this club from existing now? If it's as lucrative as you suggest, the market would jump on it already. Why don't you start a Go Fund Me?



Your consistent error in thinking in nearly every post is that if something is technically possible, it is economically possible. "Wireless" inductive power transfer has been around since Tesla (the person, not the manufacturer), and the reason it isn't widely used isn't because it's new technology, but rather it's expensive and inefficient. We could have had our electric busses and light rail use inductive power all along, but didn't because an overhead line is way cheaper and efficient.

If anything, we'll have overhead lines supplying power.



I'm all onboard with dumping political (incorrectness). It's worthless garbage in all cases.

The researcher is confined to research and not activism because people don't listen to facts, they respond to emotional fanaticism (Trump). The second someone becomes an emotional fanatic, they have abandoned their rational mode of operation.

So you see, at best a researcher can inform someone who is influential, who is then likely to take the seeds of truth and embellish them to the point of absurdity.

A true researcher takes criticism and responds to it in a scientific way. If Jacobson is sticking to political tactics rather than responding to valid criticism, he has left the arena of researcher and entered the arena of politics / religion.

Your analogy is ridiculous. As I've said, it isn't clear what the extent of threat to humanity global warming is. If you really think your analogy is valid, then you should be on a terrorist watch list as your actions towards people viewed as the steamroller would justify your emotional view of them.

*Clean Technica is a cult which sometimes happens upon factual sources of info.
'Knowledge will forever govern ignorance,and a people who mean to be their own governors must arm them selves with the power knowledge gives.A popular government without popular information or the means of acquiring it is but a prologue to a farce or tragedy,or both.' James Madison.
*the example of the meat lobbyist points to a structural impediment to the dissemination of information to We The People by a legal fiction (a corporation).
*State boards of education might have included the health information in their curriculum as a favor to taxpayers who fund public education.
*With healthier citizens,capital could be directed towards the 'impossible' transition to alternate and renewable energy.
--------------------------------------------------------------------------------------
*Since there's no conversation about climate change and it's ramifications,why would citizens have it on their minds? Why would they do anything when Dancing with the Stars or the Royal Wedding is more important?
*An AM's CLUB would only happen if people conceived a need for it.

Was World War-II economically impossible?

My powers of imagination could not conceive of automobiles operating off catenary lines.Lutz's road-based solution seemed more plausible.As I understand it,even the Hughes Electronics inductive charging technology of 1987 was near-100% efficient.
-----------------------------------------------------------------------------------
Emotion,especially fear,is a successful evolutionary adaptation.The book,'The Gift of Fear,' addresses this vestigial,ancient facility.
Since the 1890s,the advertising industry has employed it in marketing campaigns as an effective tool to motivate human behavior.Ivy Lee taught both John D. Rockefeller and Adolph Hitler how to capitalize on its use.
If you buy into Abraham Lincoln's argument that,'to know and not tell makes cowards of men,' then how could Stanford's team act any differently than they did? Climate change is considered an existential threat.There's nothing more important than an existential threat.We are free to believe whatever we want.So far.
-------------------------------------------------------------------------------------
From Lomberg:
'(Albert Gore's) supercilious attitude to our democratic freedom and contests our basic right to decide for ourselves how we lead our lives,so long as doing so does not bring us into collision with others.'
Do you see how he qualifies our right to choose? Our freedom is contextual.It's conditional.You don't trespass on your neighbor and expect forgiveness.You don't use your neighbors atmosphere for a sewer.
'Your freedom ends where mine begins' kind of a concept.(don't tread on me)
The steamroller was meant to be a dramatic metaphor to touch on just how serious business as usual might be to Jacobsen.
I'm not apologizing for him.His actions are just information.
Molina and Rowland were eviscerated for their revelation about chloroflourocarbons and the ozone hole in the 1980s.Most people alive today might be thankful that they came forwards with their inconvenient truth.

Hughes Electronics developed the Magne Charge interface for General Motors. The General Motors EV1 electric car was charged by inserting an inductive charging paddle into a receptacle on the vehicle. General Motors and Toyota agreed on this interface and it was also used in the Chevrolet S-10 EV and Toyota RAV4 EV vehicles.

The problem isn't so much one of education, it's of interest. Knowing something is meaningless unless we're motivated to do something about that knowledge. As you point out, people want to watch mindless stuff to occupy their bored and underutilized minds.

Climate change is not an existential threat. Show me someone with compelling data to suggest it is and I'll be open to the idea. I've not heard anyone but environmental extremists suggest humanity is seriously threatened by GW.

I agree that freedom is conditional, which is why I'm not a Libertarian. Their attitude often is something along the lines of "what do you care if I pee on my end of the pool".

The thing is, when everyone is peeing, it takes a united effort (global) to have a meaningful impact in a just way to every person.

At Permalink #1977 I posted about Software Defined Electricity. The story was reported on Slashdot with a link to this discussion on EEVblog: https://www.eevblog.com/forum/dodgy-...l-electricity/. cdoerfler is apparently a principal in 3DFS and was quoted in the Vox article.

Same as it ever was.

It might have been Jerry Seinfeld who made fun of Tabloids at the supermarket checkout line,with headlines like 'Child Who Cries Rocks!',or,'Woman Gives Birth To Her Own Mother!'
I had an uncle who was fond of saying that 'Dog Bites Man!' isn't news,but 'Man Bites Dog!' is.
Lomberg cited a textbook for journalists which emphasized using a shock and awe sort of drama when constructing story lines for publication/broadcast.
-------------------------------------------------------------------------------------
I keep my radar on for anything to do about the climate mentioned in the media.And,other than tangential comments made on AccuWeather,and the PBS NewsHour/NOVA,It looks like an abyss out there.
If climate change isn't news it has no importance.If it was important,all the networks would be covering it.
If it's not important,we don't pay attention to it,and are unaware of developments.
--------------------------------------------------------------------------------------
If you have access to Science or Nature,you can read the articles/papers/etc.. right from the climatologists' mouths.
They're observing changes which are exceeding the best model predictions for some of the parameters which are kinda the canaries in the coal mine of change.
Latent heat of fusion is a compelling mechanism with respect to ice and snow.
The Btu's it takes to melt 1-lb of 32F ice,into 32F water,once the ice is melted,will go on to raise the temp of that 32F water to 176F.
And without the 85% reflective index(albedo) of the ice/snow,we now have dark water which absorbs 93% of the incoming solar radiation,exacerbating and amplifying the warming.Evaporation,atmospheric rivers,Salinity,density,stratification,light penetration.................the list goes on and on........... reflects these self-reinforcing feedback loops that are scaring the ....out of some observers.
Dissolved Methane,frozen Methane which are more potent GHGs increase the warming.70-billion metric tonnes of Methane release potential.
Warm water intrusion is attacking continental glaciers from below the water line,Greenland and Antarctica.Earthquakes from continental rebound as weight of ice sheets diminish.
Without ice shelves buttressing the continental ice sheets,they accelerate calving events,with ice bergs which raise sea level.
The polar jet is being deformed by warmer air infiltrating the poles,which upsets the jet stream which is experiencing excursions below the equator at times.Meridonal transits can lock geographic locations into a high pressure areas for weeks at a time with no relief from heat events.Thawing permafrost.
Extreme weather events are becoming less rare.
It just goes on and on.
Heat deaths.Drought.Crop failures.Seawater infiltration into freshwater.Grounded airline flights do to density altitude go-no-go situations.Flooding,more powerful storms.Forest kills as insects migrate north.Wildfires as dead forests provide fuel for lightning strikes.Then mudslides after severe rain events hit the wildfire locations.Tropical diseases are moving north.Hurricane/cyclone/typhoon intensification.
We know from climate proxies,that in the past,Earth has undergone 'abrupt' climate change in as little as a decade.
We can't genetically engineer plants to deal with something like that.Species of flora which cannot move north face extinction.Photosynthesis ceases at 104F.Leaves wilt,pollination stops,solar capture is reduced,stomata,which otherwise absorb CO2 for growth close down.
Phytoplankton which provide our breathing oxygen are negatively impacted by warming ocean temperature.Ocean acidification (lobster,starfish,zooplankton,shrimp,coral die off).Algal blooms,red tides,dead zones,beach closings,coastal nuclear powerplant shutdowns (cooling failures),nuclear-powered military vessel shutdowns (cooling failures).Heat indexes as high as 176-degrees F in the Middle East.
It goes on and on.And its the speed at which its happening that's alarming observers.
Last week we had 109-degree F heat index here.
It's an interesting movie to watch!

If you had 2 laminated iron cores in contact with each other only then can you begin to approach 100% efficiency.
I didn't even know air coupled inductors could reach 86%.
My J1772 is around 99% efficient.

There's nothing wrong with j1772 or CHAdeMO.
J1772 is simple and it works.

The stupid EV1 paddle charger combines the most of the cost and complexity of CHAdeMO with the limited power of J1722.
I can buy a 3.8kw J1722 for under $200, sometimes you can find a first gen leaf 120v J1722 brick for a little less than that and 6.6kw J1722 setups range from $400 to $1000.
I doubt that paddle charger thing could have been built and sold for much less than $1000.
It's like they really worked hard to develope the most complicated answer possible for a very simple problem when they came up with the padel.

An alarming compendium. But no mention of the electrical effects on weather, earthquakes and health and cognition*.

Yesterday, Suspicious 0bservers was complaining that the USGS called that latest volcano in Hawaii an earthquake (that sent a plume 12,000ft in the air. ). Today they let go of their explanation of an 'exploding gas pocket and admitted it's another volcano'. They're getting bigger.

edit:
* No sooner do I post 'health and cognition, and i find this from S0:

Efficiency of road embedded inductive charging systems isn't even the big issue that precludes it's consideration. The hardware is massively material intensive. building out massive coils into every highway at a capacity to keep big trucks nominally charged is another fantasy concept that can't happen.
.
Even fixed inductive charge stations for autonomous cabs and busses are of limited value because the charge rates are limited to whatever massive, heavy, and expensive, size of a coil that you feel like dragging around in the car. Electric busses will be much better to have the operator just step out to plug in for a few minuted while people get on and off. And if you want a a high tech solution for charging an roving autonomous fleet, I would recommend developing a standardized contact plate system that would reach up and touch the matching plates on the underside of the vehicle after sliding covers are retracted.
.
In large cities where travel areas are dense it will be a long time before even this makes more sense than just having human attendants running up and down at large charging lots, plugging and unplugging vehicles to keep them charged.
.
Overnight inducutive charging systems in a home garage for people that are too lazy to plug in might find a few takers. But thinking that we are going to run heavy transport on inductive highways is , again, impossible.
