Current technology for piston engines in cars is around 20% efficiency.

200 times better is - 4000% efficiency!

That means you get 40 times the energy out than what you put in.
This is a "Perpetual Motion Machine of the first kind", something that violates the laws of thermodynamics.
Take a working model to the patent office, and you will make a billion dollars (unless someone comes up with a quite different way that produces 50 times the input energy...).
See: https://en.wikipedia.org/wiki/Perpetual_motion#Classification

I was going to make a comment exactly like this one when I got off from work. Looks like you beat me to it. Now I have to wonder what kind of math paulgriffiths used to reach his "200 times more power efficient" figure.

Well, goes like this, if can give it 10 times more power then can make it 10 times smaller at the original power output, thus also 10 times lighter... thus somewhere up to 100 times more efficient.
Now, car engines are terribly inefficient because cars weight 100 people and if 1 person can push a car 10 mph then 100 could push it 1000 mph if using some sort of gear.

Something  I am wondering about is, if we have so many magnets have we changed the north pole? Is the effect now wider or more concentrated as most magnets are in the northern hemisphere.

So, all new motors, speakers should be shielded.

You need to read up on the inverse cube law for a start.

[evan_au]

if 1 person can push a car 10 mph then 100 could push it 1000 mph if using some sort of gear.

The power to overcome air resistance grows as something like the square of the speed. So using 100 times the power will not get you 100 times the speed.

The air resistance increases even faster as you approach the speed of sound, so you won't reach 1000 mph this way.

This sounds like the argument "If one woman can deliver a baby in 9 months, then 9 women could deliver a baby in 1 month". It just leaves out too many factors.

Show us a photo of your working model, and report on what power it can produce!

Cars moving too? Stroking metal against a magnet makes them magnetic though cars change direction. (1 meter engine * 1500 meters * 10 * 365 days * billion cars is a lot of meters(5,475,000,000,000,000 or 5.5 quadrillion meters).
The earth's surface is 510,000,000 square miles(1,147,500,000,000,000 square meters).
   
5,475,000,000,000,000 /  1,147,500,000,000,000 = 4.77 times a year the total earth surface is stroked by car engines. A concern?
Earth may not have a core and may just contain metal? Say 1% metal. 3000 miles deep of it.
4.77 times over 100 years is 477 times a meter engine stroking the earth( about 1/3 mile).
1% of 3000 miles is 30 miles.
So we have stroked about 1/90th of the magnetic field?


So all Magnets & Electromagnetic devices must be shielded, Transport, Motors, Electricity Transformers, Wind Farms, Particle Accelerators etc...
Electricity cables too...

I have to repeat this unless something wrong with my math. Also magnets are a lot stronger magnetic influence than just metal?

This is NOT an emergency. If you don't know electronics don't go fixing your washing machine. (Motor will overheat or may not be as powerful, electronics will pump in more power, both burn out and cause a fire. If you advise anyone to do this then you will probably burn.

Since there is metal in the sea I see this only as a current temporary problem?

Humanity has practically nil effect on the properties of the Earth's core, so no, we are not changing the North Pole.

Well, stroking 4.77 times the earth surface with electric cars(being 1000's more influential than just metal is 3 miles of intense magnetism, will defiantly swing your compass.
It may remove faster that it is being produced. I'm sure your get lost with your compass in a street let alone a car park.



I would respect an electric car manufacturer that shields it's motors anyway because don't want the iron in my blood pulled to my skin. Or having iron deficiency(In women of childbearing age, the most common cause of iron deficiency anemia is a loss of iron in the blood due to heavy menstruation or pregnancy. A poor diet or certain intestinal diseases that affect how the body absorbs iron can also cause iron deficiency anemia.Iron is important because it helps you get enough oxygen throughout your body. ... If you do not have enough iron, your body makes fewer and smaller red blood cells . Then your body has less hemoglobin, and you cannot get enough oxygen. Iron deficiency is the most common cause of anemia.).

Seawater contains no iron but does contain 0.1% magnesium. An electric car magnets could be 1000's times more magnetic influence than just metal. So 1000's * 0.1% is 1,000,000 times more influential than seawater which is probably the only stuff naturally moving on earth.
Get my drift/current when a car goes 70mph? Sea moves about 5mph. So electric cars are 12 million times stronger than the sea per square meter.
Sea is 315,000,000,000,000 square meters. So (1 billion cars * 12 million) / 315,000,000,000,000 = World using non shielded Electric car magnets being 38 times more influential problem than the sea.

So yes I would say our current magnets & electromagnets are already a concern.

I using math is clever and world shielding it's magnets & electromagnets will be wise.

\i would have no respect for a car manufacturer who didn't  understand that the iron in blood isn't metallic and is actually slightly repelled by a magnetic field (as is water).

I also don't have much respect for people who randomly put nonsense in big letters and/ or funny colours.

I presume you forgot to read up on the inverse cube law too.

Don't you think it might be a good idea if you got over your delusions of adequacy, and learned some stuff before pontificating nonsense?

A magnetic compass still pretty much works as well as it did in Columbus's day.

Your calculations make no sense.

(1) Magnesium is not ferromagnetic when it is a metal, let alone when it is an ion dissolved in water.
(2) Where did you get that figure for an electric car motor being thousands of times more magnetic than "just metal"? I'm guessing you pulled that out of thin air.
(3) The direction and velocity of both cars and seawater varies immensely.
(4) Knowing the surface area of seawater is insufficient to calculation how magnetic it is. You need to know its volume as well.
(5) As Bored Chemist pointed out, you aren't considering the inverse cube law.

Your calculations are completely meaningless.

deoxygenated? If you do not have enough iron, your body makes fewer and smaller red blood cells . Then your body has less hemoglobin, and you cannot get enough oxygen.
Snowball effect?

The magnetic fields of MRI machines are routinely over 40,000 times stronger than the Earth's magnetic field. If they don't harm hemoglobin, then a bunch of electric cars aren't going to either.

Now very strong magnets over many hours over many days is a lot of time compared to a MRI scan even if MRI is 40 times stronger(isit?).

You have any evidence that chronic exposure to strong magnetic fields has any effect on blood oxygen? Moreover, don't you realize just how weak a magnetic field from even something like a powerful neodymium magnet is if you are so much as ten feet from it? That's what makes the inverse cube law important: magnetic field strength falls off very rapidly with increasing distance.

sorry, sea is only at it's very deepest 7 miles. So 38 times will say is 12?

And what equations are you using to get that result?

I said ferromagnetic. That is the kind of magnetism that common magnets have. Paramagnetism is usually much, much weaker.
