How about if you don't have air conditioning? A lot of people in the ME can't afford it and the power is often intermittent at best in many places. Also, clean water can be a luxury in many places in the ME.
Years ago a good friend of mine worked on a project to research if smart guns were possible. The problem was that they succeeded and they had built prototypes. The way it worked is that the police officer would wear a special bracelet with a transmitter. A detector in the gun would prevent the gun from firing if it did not detect the bracelet. It also could detect if the gun was not being held properly (i.e. the wrist bent) and would also prevent firing. It worked extremely well. The police who tried it loved it. If someone tried to wrestle the gun away from the cop it couldn't be fired. If the cop's wrist were bent from someone trying to take the gun, the gun would not go off. It also worked with existing guns and was fairly inexpensive to implement but it was also very effective and reliable in their testing. The local police department who was testing it wanted the technology.
The problem was when the senators that commissioned the study found out that they succeeded, they decided to bury the report and changed the definition so that a gun had to be able to determine the intent of the shooter (an impossible task). The gun industry was also totally against this.
In my state 30% of the power comes from renewable sources. There is virtually no coal and the rest comes from nuclear and natural gas. Every year our power gets cleaner as more renewable sources come online. Across the United States the use of coal is declining due to costs and pollution.
My father just retired two weeks ago to the day. He's into his 70s. While still working and pulling in a very nice salary he had to take social security whether he wanted it or not. He was also forced to take money out of his 401K which he didn't need or want to do. I doubt he'll sit at home idle for too long, though.
There's also a lot of baby boomers retiring, hence a lower participation rate. The number of illegals has been dropping in recent years. Some industries are also hit hard and unlikely to recover (i.e. coal) and others show no signs of recovery (oil). For example, if you're in West Virginia and you can't find work in the coal mines, it'd be stupid to look for work in West Virginia or continue that line of work.
It sounds like a fucked up state. I have a friend who ran into similar stuff in Utah. To qualify for food stamps you had to make less than around $3500/year. He made more than that, but not a lot more. Unemployment required you to have worked a 9 month stint to qualify and since the jobs tended to be short lived he couldn't qualify for anything. There were housing programs, but they only kick in once you're homeless and do nothing for someone about to go homeless. It seems totally fucked up. I would think it would be a lot cheaper to help someone before they end up on the streets. It would certainly help on things like medical.
I'm sure a lot of this came after the Three Mile Island accident. The problem is that most people today think of Chernobyl or Fukushima. Chernobyl was an accident waiting to happen due it its inherently unsafe design. Japan also has had a history of poor maintenance of their nuclear facilities and Fukushima was an old reactor.
Other events have also taken place like the vessel head of the Davis-Besse reactor degradation.
If you remove the regulation and inspections, the utilities have been shown time and again they'll do as little maintenance as they can get away with. I know I have zero trust in PG&E, my energy provider. They blew up a neighborhood in San Bruno due to shoddy records and shoddy maintenance. Similarly, the Rancho Seco station (the closest one to me) was shut down years ago because of constant safety problems. It had the third most serious safety-related occurrence in the US..
I can give you a perfect example, while it may be less than 100 miles it is still a very significant distance. I often travel through Bridgeport, CA. It used to have a grocery store and a general store. The grocery store closed, leaving only the general store, which has a limited selection and prices are high. When gas was $3 elsewhere, it was over $5 there because it is so isolated. It's a half hour drive to Lee Vining, another small town. The closest major town is Gardnerville, NV, which is 65 miles away or Bishop, CA at around 90 miles away.
Now this is in eastern California. Head over to places like Montana, Wyoming, parts of Texas and other low population states and you would have much further to travel. Small towns typically have only one grocery store and not all small towns do. Read about what some people are dealing with when the the Walmart in their small town closes, leaving the town without a single grocery store.
Sure, in a big city there are a bazillion places one can go for shopping and services. In the rural areas, not so much.
I wear a Casio watch. I never have to charge it or set it since it charges via solar and sets itself over RF. It also is fairly rugged. I tend to be hard on watches so it frequently gets banged about. I rarely have to so much as push a button or touch it.
I don't need something to tell me all my notifications. I'll look at notifications when I'm damned ready to (if ever). It tells me the time and date, which is what I care about the most. If I wanted something to monitor health it certainly wouldn't be an iWatch because it doesn't work very well. I have a friend who was CEO of a company that designs sensors for that sort of application and he was able to explain why most devices like the iWatch don't work very well and the fact that there's not much Apple can do to fix it. He said rather than licensing his company's technology, Apple would try and develop their own, though it would likely require hitting a number of his company's patents (when has that stopped Apple?). The other problem is that the sensor needs to be in direct contact with the skin. A normal watch on the wrist doesn't work that way. It's basically "You're holding it wrong." like with the Apple iPhone 4. Also, the iWatch is not very useful without an iPhone. I would also be very frustrated about having to charge my watch all the time.
The problem the other car manufacturers have is the dealerships. Dealerships make most of their money from service and financing, mostly from service. There's a lot less service for EVs. Elon has also said that they don't want service to be a cash cow like it is for dealerships. Dealerships will even lose money on a car if they know they can make it up with service and or financing. Dealerships don't have the manufacturer's best interest, either. Dealerships will push the cars that make them the most money, and it's not a car that requires less service.
EVs need a lot less service than ICE vehicles. There are far fewer moving parts. On my model S, the electric motor is lubricated for 12 years. There are no regular oil changes. There's no belts to change, spark plugs to replace or engine air filters. They can't try and tell you you need your injectors cleaned. There's no fuel pump, transmission or clutch. Even the brakes will last a lot longer due to regenerative braking. There are only a dozen moving parts in the entire drivetrain from what I have been told. There are not a bunch of things bolted onto an engine since they're all electric. The power steering and AC compressor are electric. An electric AC compressor is totally sealed and is typically a lot more reliable than one driven off of the engine. There is no starter motor to go out or alternator to go out. There's no ignition system to wear out. I don't even need to take it in to flash firmware updates. There still is a 12V battery, though. For a while they were going through those quickly until one of their software updates reduced the heavy cycling of the AGM battery that tended to kill it every 12-16 months.
The AC induction motor has no friction points except the bearings on the shaft. A well-designed power inverter should last a very long time. Even the batteries should last a long time. Panasonic says the ones in my car will have 80% capacity after 3000 cycles. That's over 600,000 miles! Even if they do have to replace the battery, it takes very little time (the battery swap station at Harris Ranch takes around 3 minutes to do a battery swap). Removing the motor and inverter is also fairly simple to replace compared to a gasoline engine since the number of hookups is significantly less and the whole module just drops from the bottom of the car.
There is still service that needs to be done. I have yearly service on my model S. They perform a wheel alignment, rotate the tires, fill the windshield fluid, change the wiper blades, change the cabin air filter and check everything. Every couple of years they also flush the brake fluid and I wouldn't be surprised they change the coolant.
I sold my old Prius to my parents. The touch screen later stopped accepting touch input. The dealer wants well over 5K to replace it with well over $1K for labor. According to a Youtube video I found it takes less than 20 minutes to replace yourself, and replacement units can be bought on Ebay for under $300.
On my model S I accidentally broke one of the clips on top of my car for a roof rack. The only way to repair it is to replace the entire panel, which has a clear-coat finish on it. Total cost, including labor to replace it? $175. If it had been my Prius, Toyota would have found a way to charge over $1000.
The stock is quite volatile. I'm kicking myself that I didn't buy a lot more stock at $38. I bought some stock rather than put money in for a future battery replacement before I got my model S in 2013. I can buy many replacement batteries having spent far on the stock. If Tesla is able to execute I think there is a good upside. Tesla could be profitable any time they want but instead they are investing big time on R&D and building out their factories. I may be emotionally invested, but every single investment I have made (not following anyone else's advice) has done extremely well in the long term. Would I buy more stock now? Only if I see a big dip, and I'm kicking myself that I didn't do that the last time.
Tesla has proven that they have strong demand for their products without any advertising other than their showrooms, though I heard that the Superchargers are budgeted under marketing.
You heard wrong. I've had my model S for over 3 years and have about 40K miles on it. I have not seen any noticeable degradation in range. The Panasonic cells are rated to have 80% of their capacity after 3000 cycles. 3000 cycles is at least 600K miles with my 85KWH battery pack. The new cars have an even bigger pack (90KW) except for the lower end ones (70KWH). If I consider 200 miles of range per cycle it works out to 600K miles. I easily exceed the 200 mile range on a charge.
The loss should be much less at 100K miles. I have 40K miles on my model S and haven't noticed any drop in range. Panasonic says that the batteries will be at 80% capacity after 3000 cycles. 3000 cycles on my P85 is in excess of 600K miles. 100K miles is less than 500 cycles.
I haven't noticed much loss in my Model S after over 3 years and almost 40K miles. My previous car, a Prius, had no loss in mileage after 100K miles. The losses in the other cars are going to be much higher because of the much smaller batteries. The loss of capacity is due to cycling of the battery. For my P85, 1000 cycles on the battery is around 200K miles. The batteries should be good for longer than that. These are automotive grade batteries, not the crappy ones they put in most consumer devices.
It charges at 240V, so under 1v is under 1% loss. I doubt there's any noticeable loss at the connector since it is designed to handle far more current when supercharging. The inverters for charging the battery are also probably quite efficient, probably over 95% and more like 96-97% efficient. The wireless charging would be in addition to the normal losses. The incoming AC would need to be converted to DC, then converted back to AC at a higher frequency. Then there are the losses involved in the energy transfer across the air gap.
One other problem is that with Tesla's skateboard design is that there really isn't any good place to put the receiving module. You wouldn't want to mount it under the battery since you would be affecting clearance as well as aerodynamics. The area aft of the motor and inverter isn't a good spot either since it would be further away. The area in front doesn't have a lot of space either.
There are far better solutions than wireless charging. Why not instead just have something that extends a plug upwards into the car, or productise Tesla's robotic charger? I imagine it might even be cheaper since far less high power electronics would be needed.
I have a friend who is TG and was born female but in every sense identifies as male except what's between his legs. Should he be forced to go into the lady's room despite looking and sounding male? Everyone always assumes it's male to female. That may be a high percentage of cases, not everyone is male to female.
Personally I don't see what the huge deal is. When I was in college, the bathrooms in my dorm were non-gender specific (with multiple stalls). It was no big deal.
LGBT is not new. The only thing that is new is that people are now public about it. I know several transgender people. They basically are the sex they identify with. When they study the brains of transgender people, their brains are wired like their identified sex, not their biological sex. Some of it is likely genetics and some may be environmentally caused (look up the effects of BPA which is a very common plastic additive).
Not all are male to female. I know one person who went the other way. Other than being born the right sex, the people I know are generally rather normal. I know two TG people who I consider extremely smart, some of the best software engineers I've met.
For these people it's no more a choice than it is a normal person's choice to be male or female.
What happens if you're in a small town and the grocery store decides to discriminate? Or if all of a particular type of business? Or real-estate people? They could bring back red-lining. The moment it's OK for one business to discriminate, it's OK for all businesses to do it.
As it is, there are many places in this country where people have to drive 100 miles to the closest grocery store.
What happens if the local religiously affiliated hospital decides to discriminate?
If you provide a service to the public, you must accept the public, you cannot discriminate who you serve within reason. (I.e. shirt and shoes required, or nicely dressed in a fancy restaurant). A public facing entity should not be able to discriminate based on religion, ethnicity, sex or LGBT. If you don't want to serve everyone, don't open a public business.
DC cabling is very efficient, especially when you consider the fact that the cabling in a Tesla is designed to handle far, far more power. Power loss in wire is non-linear based on current, it's basically (I^2) * R. The loss in the flexible cable going to my Tesla loses less than 1V at 20KW. The cable gets a little warm, but it's still quite comfortable to touch. If there were significant loses anywhere near the loss due to wireless charging then UL wouldn't approve it. It would turn the copper cabling into a 2000 watt heater if it's only 90% efficient.
The loss when charging my Tesla at 20KW through the cable is fairly minimal. There is an 8V drop between the meter and the shutoff switch in my garage over a 100 foot run, but the drop between that and my car going through the flexible wire is fairly minimal, maybe a volt. The cable gets warm, though not uncomfortably so. One of these days I need to track down where the 8v drop is coming from. At 10KW the drop is negligible.
Personally I don't see much need for wireless charging, at least for Tesla. The Tesla connector is much nicer than the J1772 connector. The mechanical design of the connector funnels it into place, rotating it as needed in the process so the connector is basically self-aligning.
It takes me under 5 seconds to plug my car in, including the time spent taking two steps back from the driver side door when I get out of my car. It isn't critical how I park my car, and when I pull my car out of my garage there's nothing on the floor when I back out. There's nothing added under the car either, no extra weight or complexity, nor anything reducing the clearance between the battery and the road.
10% loss at 20KW is still a lot. It's like having a 2000 watt heater in the garage while charging, in addition to the heat generated by charging the car.
I usually charge my car at 10KW since the loss is significantly less (loss due to current is non-linear).
I had a coworker who lives in a condo who bought a model S. He had no problem getting a charger installed. It helps that in California HOAs generally cannot block the installation of EV chargers.

Personally I don't see much need for wireless charging, at least for Tesla. The Tesla connector is much nicer than the J1772 connector. The mechanical design of the connector funnels it into place, rotating it as needed in the process so the connector is basically self-aligning.
It takes me under 5 seconds to plug my car in, including the time spent taking two steps back from the driver side door when I get out of my car. It isn't critical how I park my car, and when I pull my car out of my garage there's nothing on the floor when I back out. There's nothing added under the car either, no extra weight or complexity, nor anything reducing the clearance between the battery and the road.
10% loss at 20KW is still a lot. It's like having a 2000 watt heater in the garage while charging, in addition to the heat generated by charging the car.
I usually charge my car at 10KW since the loss is significantly less (loss due to current is non-linear).
I had a coworker who lives in a condo who bought a model S. He had no problem getting a charger installed. It helps that in California HOAs generally cannot block the installation of EV chargers.
