They plan on doing a stretch of highway that will charge the car as you drive.

efficiency of led bulbs have been preached also. But every good long term led bulb I examine has a huge heat sink and heat dissipation system when it is of size.
The ones without the head sink don’t last long but they are efficient for the moment.
So, cite your source, I don’t believe you.
“Well here is someone who disagrees.”
That is for phones, not EV’s.
Live and learn.

ROTFLMAO!
I don’t think anyone with a pacemaker for instances, should be around when someone is charging their car
Especially when laying in a pool of salty water from melting snow off cars in states like NY.
Make the pad waterproof and put it on the driveway, away from the house.
Inefficient at high power. Transformer losses. And here you will have a very inefficient design as it is not all contained in one well designed package.
Is that before or after the car burns up in the garage?
Inductive charging involves large magnets. Anyone in range with a pace maker is at risk.
Check the fine print on your inductive stove — certain pacemakers will ....... “not” if within arm’s reach.
Of course, few will care. But, when their cell phones and other devices that charge magnetically suddenly catch fire — oh, my!
Interesting. I hadn’t thought of a pacemaker.
I’m pretty sure I wouldn’t want any magnetic media anywhere near it.
GM offered this on the first GM EV more than 2 decades ago. The technology isn’t new, at all. One problem is that it’s not very efficient.
If you can charge up while parked in front of somebody else’s house and you got something good going.
And the democRATS will now build much more electricity generation. /ssss.
The democRATS want to limit EVERYTHING they possibly can, except for themselves of course. Between the thousands of years of oil and natural gas under our feet, we could also build next generation nuclear plants and have very, very inexpensive and abundant energy. That leads directly to more freedom, and the democRATS despise free people.
Can’t see how it is wireless if there’s a wire from the pad to a plug in the garage. Of course, that means you’d have to make it home every night. What’s that going to do to your home insurance premiums? What about the extra pull on the power grid?
And if it works at the range of a foot, what does it do to other devices/items in the garage?
ROTFLMAO!
Read the WHOLE article. There is a comparable efficiency at a VERY PARTICULAR RANGE OF CHARGING, and that is a very LOW range of charging.
They quote 20% to 80% state of charge. Why the range? It is time sensitive. How confident are you going to be with a 20% charge? Of course eyes go to the 80, but there is also a 20.
“Level 2 home charger operates in the range of about 83-94% efficiency grid-to-battery depending on which one you buy.” Now that is quite a loss of efficiency to compare to. THAT IS A HUGE LOSS OF EFFICIENCY TO CONVERT ENERGY.
Now regarding cell phones. No one is going to wait a whole day for efficient charging, It is a lower power consumption and we can trade efficiency for convenience. Add another 5-10% efficiency cost to a EV for convenient/ fast charging, and there are problems and cost factors that get serious.
Now don’t laugh at the LED bulbs. Yes, the old led on the calculators were almost 100% efficiency. That was the selling point, but achieving in application and manufacture is another point. That does not mean all LED’s lights are efficient. Take a look at the higher wattage or long lived bulbs. They have massive heat dissipation systems. HEAT is inefficiency.
The short lived “fashion” when I grew up was “appropriate technology.” It was understood that in certain situation certain technology was a good thing. IF you changed some aspect of the system things changed.
Liberals look at one or two data points of a complex system like climate and think they understand it and can control it.
I am not against EV, they are appropriate for some people and some situations. But note the govt thinks one size fits all and will force you one way or the other. and in their “one size fits all”, THEY MAKE THINGS WORSE.
The fast charging version can also cook your dinner.
Keep your kids out of the garage as well as all metal objects.
Yeah, well.
The liberals that worship EVs and buy the damn things already has brain damage, so who cares?
