Get a bigger Pelican case. The ONLY thing that should penetrate the case are sensors and power feeds - NOTHING high-speed or digital off the CPU. If it's environmentally sealed, then only use environmentally sealed stuff outside. EVERYTHING ELSE goes in the Pelican case. Screw it down (easy to drill through them, use a dab of silicone sealant on all screws/washers) internally. Stuff that can handle connectors like cameras, GPS antennas, and power won't have a issue with a mil-spec circular connector.
A torus is the folk who walk aroun an take photos of stuff an eat at yer local restraunt and thing... Usully show up on big ol bus and wear funny shorts an hats.
Alaska is North of Japan, due to being higher in Latitude. Just like San Francisco is North of Los Angeles. Heading straight North from Los Angeles and you miss SF by quite a bit, as SF is actually NNW of LA; but it's a general direction that matters here. in that regard, Alaska is North of Japan, and Japan is North of Hong Kong.
Way too low to be any impact to life, and probably below the level of detection just 10 years ago. The problem arises when we can detect things - way below safe levels - and people go OMG WE HAVE XXX PRESENT!
Put the electronics in a Pelican case. Use a motorcycle camera on the outside. Use waterproof, circular mil-spec connectors for the camera and power supply to the case. Done.
Which is why the GP's contention of in China "you can make purchases via face recognition" is irrelevant in a discussion about receipts. Receipts as a whole are irrelevant in China.
The charging system for an EV starts with electricity at the wall and includes components from there all the way to components inside the car connected to the battery. All have impacts on efficiency.
Yes, and changing that last link from a connector to an air-core transformer is necessarily more lossy. I don't know why you have an issue with this. The math is right above - coupling factor. You will never be as efficient when you terminate your charging system with a transformer (air core or iron core, although iron is more efficient) as compared to a hard-wired connector. Just not going to happen.
Maybe the rational approach is to realize there is no one-size-fits-all solution; a transport infrastructure designed for cities won't work in rural areas, and unimproved roads in rural areas doesn't work in cities. You need both, where appropriate.
Being able to accelerate quickly and well beyond the speed limit has saved my life
And you can, under the EU proposal.
For now... If the powers-that-be decide your stretch of road is now "too congested" - too bad. It's essentially a throttle-by-wire-by-bureaucrat solution.
In China, when you buy any item worth returning (say, a new electric tea kettle) you also try it out right in the store to make sure it works - because once you leave, there IS no warranty. Regardless of what anyone says, or is written. No warranty will ever be honored, so why worry about a receipt unless it's for tax/business purposes?
Just remember, according to California and Prop 65 - toast and prune juice will give you cancer! They are only looking out for you. Now ignore the pile of poo outside your door in SF, mind the needles in the grass, and eat your tofu and drink your boba (with no plastic utensils, straws, or paper receipts mind you - it's for the Earth, after all...)
The EU just abandoned their 2050 climate goals because there was no chance of reaching it. And Germany has seen coal use slightly rise over the last 10 years - no chance of meeting their own 2020 and 2030 commitments.
The future isn't solar and wind (because it's not working); it's nuclear. That is the only way forward out of pollution and limited power.
Why would I need to? I've never asserted that. I suggest that you stop strawmanning me and keep to arguments that I have actually made.
Because the original article that I said was wrong - that you too offense of - made that very claim. That it was more efficient than a connector. And that is flat out wrong.
True or False. Measured from wall to battery, modern inductive chargers for electric battery vehicles are in the same efficiency range as modern wired chargers.
The claim was more efficient. Nice goal-post move... And it is false. Take any charger, add a wireless transformer system to the output - and you've made it quite a bit less efficient. Provably so.
And that right there is the fail. Show me for a transformer how you can get a K value (coupling factor) of 1. You can't - unless there is no secondary (which means - it's not a transformer). Thus there is ALWAYS a loss in a transformer. Apply the low permeability of air (1, versus 1000+ for steel) and you have even more loss. It doesn't have to go beyond that..
If there is a transformer, it WILL be lossy. If there is resistance, it WILL be lossy. It will never be as efficient - laws of physics and such. I would assume a STEM person would understand that...
Lastly, add in the permeability of the core material - steel versus air - and it is quite obvious why an air core transformer will never be as efficient as a steel core, let alone a connector.
You don't want to believe it, fine. Physics says you're wrong. Go talk to your local EE professor and ask them if an air-core transformer, with a wide separation of misaligned coils, will be more efficient than a direct electrical wired connection. Learn for yourself.
The inventor of the World Wide Web, hypertext, and linking was European, and invented it all at CERN in Europe. And now Europe effectively destroys the entire thing by taxing the very item (hyperlink) that created it all...
Truly, it is just a matter of time before the EU taxes air and sunshine...

Your mastery of the English Language is ribbeting!
If the solar wind was strong enough to strip away CO2 and CH4, it would have also been strong enough to strip away water vapor.
Correct! Now, how long does it take for water to sublimate into vapor to be stripped away? Does it happen all at one time?

Business is just trying to catch up with celebrities and government officials...
Yep! And you just punted on every commitment you had made prior...
Personally, I don't want either - but I'll take my chances with the extremely rare latter than the universal former.

There has to be a way we could work AI and blockchain in here to make it more secure...

All I've been arguing is "as efficient".
And that right there is the fail. Show me for a transformer how you can get a K value (coupling factor) of 1. You can't - unless there is no secondary (which means - it's not a transformer). Thus there is ALWAYS a loss in a transformer. Apply the low permeability of air (1, versus 1000+ for steel) and you have even more loss. It doesn't have to go beyond that..

Actually, I am an electrical engineer, I've designed many power systems, and it's quite obvious. for anyone with first year EE or physics.
First, start with a primer on air core transformers.
Then check a simple model and experiment (which confirms the model) to see what kind of coupling you can get. See slide 5 about the coupling factor.
Now learn about how coupling factor - leakage inductance - affects efficiency.
Lastly, add in the permeability of the core material - steel versus air - and it is quite obvious why an air core transformer will never be as efficient as a steel core, let alone a connector.
You don't want to believe it, fine. Physics says you're wrong. Go talk to your local EE professor and ask them if an air-core transformer, with a wide separation of misaligned coils, will be more efficient than a direct electrical wired connection. Learn for yourself.
Except is is flat, shiny, and has rounded corners.
