How much electromagnetic radiation do those car put out?
Will the battery price ever go down?
Tons! You'll probably get a tan just driving one.
The precious metals that go into electric cars are a limited resource.
Or glow in the dark!
I doubt it has been measured.
As far as battery prices, they "could" go down over time but I honestly think we will have another more viable gas alternative before that happens.
I just don't think EV's are the future, not to open that whole can of worms again but that's what I think. And I'm very heavily on the side of going green. But EV's just aren't and I'd rather see the infrastructure time and money go to something that really could be viable long term like Hydrogen.
E.V.'s the future?
Save the planet, huh?
So where is all that electricity coming from?
Hmmmmm your EV has a 350 mile range? how many times to you stop to re-charge if you need to go from, say, Florida to Illinois?
Hydrogen? Ever hear of the Hindenberg?
I searched using the following: Do hybrid car batteries put off electromagnetic radiation
They do give off radiation, however after randomly selecting and reading a couple of articles the verdict isn't clear. Listed below are some examples.

In theory, as more hybrid batteries are produced and if they are produced in numbers higher than demand the cost should come down.
However, as MMJ pointed out above the materials they are using are rare, and will get increasingly rare as production ramps up.
The Feds will also continue do their best to artificially suppress their prices with so called "credits".
A small amount of exposure is completely normal, the problem is how much will cause damage to the human body.
If your too close to the Sun, you fry. Would you tape your cellphone to your head 24/7? I wouldn't do it.
From all of the scientific articles I've read over the years, the verdict is still out. They really just don't seem to know yet.
" If your too close to the Sun"
* you're
.
The verdict is only out for paranoid people who don't understand physics.
.
Yes you can absolutely tape a cell phone to your head 24/7 without any ill effects. We are talking about milliwatts, up to maybe a couple of watts of energy at most. The warmth from the battery will probably be greater than the radio energy. None of it is ionizing.
.
Simply going outside will expose you to at least 1,360 watts of RF energy from the sun, for each square meter.
.
We are constantly bombarded by ionizing radiation (the bad kind). From the soil, water, cosmic rays. (On Earth's surface, they makes up about 17% of the background). Even things like bananas, and the air you breath. Your own body contains radioactive carbon. A flight from New York to London will expose you to the same amount of radiation as a dental x-ray.
.
We do not exist in an energy vacuum. You do not need to worry about cell phones and cars.
And most importantly, get your priorities straight. Don't smoke. Don't get fat. Drive safely.
and .. seriously? You're posting links from quacks, and websites that sell beanie caps to shield you from 5G??
{blackemo}:laughtertotears:
I knew you were going to respond, and you didn't disappoint.
You forgot alcohol and drugs as well.
I have zero concern about radiation. And mufflers flying through windshields as well.
All in good fun. {black}:hi:
Hey, my doctor says I can have one drink a day.
He never said how big!
Gotcha! I hate the stuff personally. Never developed a taste for it.
Seriously though, I do believe the case for too much exposure is over blown.
Until they really do a long term fully comprehensive study showing proof, I will be a skeptic that it's as harmful as some of these sites are claiming.
I think the proof already exists. There are everyday examples all around us.
A lot and no.
Fwiw. The hybrids battery for the Prius has gone down in price since it’s inception. From about $4000 to $2000 over the years. But then at the beginning of the pandemic, the prices shot up again to $4000.
IMHO, from a manufacturing standpoint, prices will go down, as it they get more efficient in making them. From a a mass production standpoint, prices will go down, as it is mass produced.
But!!! From a materials standpoint, prices will go up, as there is more demand for rare materials. From and inflation standpoint, prices will go up, well because, inflation.
Heck even back when Powell Crosley's WLW radio station was on the air with 500,000 watts of broadcast power it didn't hurt anyone, though it was reported that if you lived near the transmitter you'd hear the station through your dental fillings and light bulbs. (Yes, it's the same Crosley behind the Crosley automobile.)

So has anyone figured out what they are going to charge your for recycling those Tesla batteries that will cost you $22,500.00 in a couple of years to replace?
The health concerns from electromagnetic fields are primarily regarded as an alternating current issue due to it's constantly expanding and contracting magnetic field. It is said that the higher the frequency the greater the effect. I'm not sure if any of that has ever been borne out conclusively. Direct current used in EVs is not considered to be a health concern because the field strength doesn't change rapidly.
if you go outside on a sunny day, you are exposing yourself to EM field frequencies in the neighbourhood of 10,000 terrahertz (that's a 1 with 16 zeros after it, Hertz) and up. It doesn't get much higher than that.
Standing in front of a microwave oven packs an EMF wallop. No one seems to be afraid of them and they're not considered dangerous unless the metal can inside explodes.
Not to mention putting a cell phone up against your head.
We would all have brain tumors......
I've heard that driving a hybrid or electric car makes you sterile. 😮
Don't frighten the snow flakes
Microwaves would never be allowed to be sold if they leaked energy. They are well shielded.
That is true now. The modern ones are better shielded and have to comply with government standards but they still emit a few hundred milli gauss depending on wattage and proximity. Not much from the high frequency cooking energy but from the 60hz power transformer that supplies the magnetron.
I agree they are not a threat but they do emit EMF. That was my point.
so do light bulbs :silly:
Yes they do. It's an inescapable characteristic of AC. We are constantly exposed. I still feel fine. 🙂
uhhh... a DC light bulb does too. All light is EMF.
Yes but the magnetic fields associated with DC don't expand and contract constantly like AC. It has always been my understanding that the rapidly expanding and contracting magnetic fields have been the reason for concern regarding EMF exposure. You are correct. Any current carrying conductor weather it is AC or DC has an associated electromagnetic field.
The light itself is also is a form of electro magnetic radiation but does not have the same effect as current flowing through a wire. For example light waves/particles won't move a compass needle but the DC current flow in the lamp circuit will.
Aha! but if the compass needles were small enough, like the the size of atoms for example, light WOULD move them. In fact this is how microwave ovens work.
The oscillating EM fields that you describe (also known as light), which can be produced a variety of ways, including AC current, aren't harmful to us until the reach ionizing energies. Those start around 10,000 THz (ultra-violet light) and get up into the X-rays, gamma rays etc.
I don't think you can achieve frequencies like that with crude things like transformers, dish antennas, magnetrons etc. To get energies like that you need charged gases, accelerated particles etc.
Microwave energy is light but not in the visible spectrum and actually less energetic than visible light. The ovens work by the microwaves exciting the water molecules in whatever is being cooked, so yea I agree that light can move atoms but I think the movement in this case is random. In my compass needle example it would have been more precise to say the needle aligns it's self with the magnetic field in the conductor rather than just saying move.
I get the impression you enjoy physics?
I don't think the motion is random. The molecules react exactly how you would expect. Rotating back and forth , aligning themselves with the field, in time with the frequency.
.
By the way, I think EV's use high voltage motors with rapidly switching currents produced by inverters (like a microwave). They probably produce a great deal of EMI.
Even your traditional DC motor with commutators is going to produce enough excitation to pick up on a radio receiver.
.
I find physics fascinating.
I've always heard food cooked in a microwave oven cools down faster. The molecular alignment could be the reason now that you have me thinking about it.
These guys do an EMF survey of a Tesla with a milligauss meter. There is some but It doesn't look bad. You might find it interesting.

nothing to do with molecular alignment. The microwaves create a pattern which heats food very unevenly (hence the turntable). It also heats from the outside in (contrary to popular myth). Those contribute to the perception it cools faster. I always let my food sit a little when it's finished so that the heat has a chance to spread through the food, and then I heat it some more if necessary. This works much better.
that video made me ill . Please don't listen to a word they say.
Well thanks for that. I never thought I'd be getting cooking tips on the car care forum butcha never know....
Did you watch the video? I would be more afraid of getting electrocuted by an EV myself.
I watched it for a minute or two and gave up. Those two have no business giving advice.
And I agree ... electrocution or battery meltdown would be my biggest concern too.
Yea. I almost didn't post it because of those two but the next one looked worse.
