Yes, they are useful, but not for survival of humanity. Humans can live without cars for that matter.


Electric cars are like digital vs analog cameras, or CRT vs LED screens, etc. There are so many analogies, but it seems the "common" people are far more close to cars. It took a while for photographers to recognize and eventually accept digital photography, same thing here.

They certainly take less resources, not too much less if the country generates electricity burning fossil fuel, but less none the less.

Start with the basics, take a look at a combustion engine vs electric motors. The complexity of the first vs the simplicity of the second. As a driver, you will immediately notice the amount of extra maintenance steps no longer needed. An electric car only uses some oil for the driving wheel, and even this nearly optional.

You see, direct mechanical direction is becoming a thing of the past, and that's when you actually drive the car yourself... Same as many other input methods are no longer direct, the gas and the brakes, these made their way into conventional cars. You push the gas pedal and you are no longer pulling some lever inside allowing more gasoline flow like it used to be. no. Modern cars today are pretty much "by wire", with the "inputs" being more or less glorified digital controls that tell a computer the intention of the driver (ie, accelerate), same with braking.

Take a simple toy electric car, and you are looking at a simplified version of what you will be driving. It has a battery, it has en electric motor, and wheels. Add direction and brakes, mostly for regulatory reasons. Tesla cars are known to brake plenty with regenerative braking, meaning, if you release the pedals, the car doesn't coast as much because the regenerating of energy happens to make the car slow down so much that people call it 1 pedal driving (ie: just push to accelerate, release to brake). Many people claim they can drive without ever touching the mechanical brakes, especially when regenerative braking is set at its highest regenerative level (it can be softened/disabled). If you know car mechanics, try to digest the magnitude of simplicity this entails. You do know Tesla doesn't even bother with gear changes? Of course they don't electric motors are very efficient which is how they found their way into Rail locomotion so early in the 20th century and ever since (No diesel locomotion engine remains that drive directly the wheels, all they do is put an electric motor and a diesel generator next to each other). This is because the electric engine is so powerful under varying loads already.

So you end with: Car body, wheels, battery bank, electric engine directly attached to wheel (no transmission), lights, chairs, windshield a single digital screen (optional) and you are pretty much done. Elon Musk had a chance when he started Tesla, to move humanity into electric cars. When he started, electric cars were still seen as toys with much disdain. It took him alone to prove them wrong, as the big manufacturers didn't care, and he delivered, and the big guys now how no choice but to follow, and this is why you see many brands jumping in.

To accelerate things, the efficient electric motor patented by Tesla has been given away for anyone to use. The patent is only used defensively, anyone is welcome to use it without paying royalties, not unlike Free Open Source software.

Did i mention that, going to a gas station to "fill" disappears from your life? The idea with the electric car, is that you plug it anywhere you park. So you will see more and more parking with electricity, and less and less gas stations. Think of, places where you used to go develop your photographs, in the past these shops were all over the place, now they are hard to find, if any remain. Or you could think of VHS rental shop, now that there is digital streaming, the likes of blockbuster, once staple of living, are no more.

In the following years you will see the combustion car quickly diminish at an accelerated rate. Business like restaurants to attract customers will make sure all their park space has electric plugs, kinda like you wouln't go to a shop without wifi anymore.

And yes, the lovers of "vroom" would claim how this is the end of the world, that cars are "not fun anymore", but such is progress. It has happened to so many things already, new generations will simply not know about it. Did you know the military doesn't teach morse code anymore? Yup, it remains in movies, just like the telegraph, the record player, vhs... Maybe the television will follow, who needs it when everything is streamed online? Aside from being a glorified big display with a tuner, that tuner is having less and less use, or the ones used by cable box, digital and all, are a thing of the past. Because there is no point in getting 500 channels when you are only going to watch only a few for few hours, and its what they want not what you want anyway.

I say we are no longer waiting for the future, the cars exist, we have entered in the phase of massive global-scale adoption. China is probably coming with cheaper, shorter ranged (and probably not as safe as Tesla) electric cars, but good enough for commuters. Of course it doesn't help that Beijing is smoke city...

It will simply become too cumbersome to keep running combustion engine cars anymore. Think of this, your VHS is broken, you need to take it for repairs, can you find a repair technician quickly? Not anymore right? Those that remain are the old people who used to do it in their glory days. Same with cars.

Love it or hate it, electric cars have arrived. Be thankful if you are still allowed to direct the wheels, because self driving is also making tremendous advance. Google (renamed Alphabet/Waymo) already envisioned a car that is essentially a chair with a tablet on wheels. No wheel, pedals, no nothing. You tell it where you want to go, and off it goes. You might say that was too early but i expect this to return once the things are considered safe enough...

I wonder how the electric car owners will get on when the power companies go bankrupt.

Efficient diesel id better for the environment than electric cars, and pretty soon the politicians will have to admit that. All electric cars do is to export pollution from the cities into the countryside. However taxing diesel car owners is great for the exchequer, and they make it much easier for the police to control drivers from a remote control centre.

Also, we should dump the idea of self-driving chains of lorries, and go back to good old electric trains.

This is an interesting question. In my opinion, Tesla has the best electric cars at the moment as Mr. Musk spent a lot of money fo the R&D department and they are way ahead of the others. To answer the second question I would say that yes they are very important for the environment. I wouldn't say for the survival tho. But we can slowly start saving the planet if more and more people have electric car. On the other side it will also be cheaper to drive electric.

We are near have shortages of electricity and how can electric cars help save the future?

What I want to know if people can generate cars that will run using trashes because pollution is killing us now and with the help of another innovative works let’s see if they can handle creating moving cars that don’t need electricity,gasoline or even solar power

No, it's not, many things are essential to our survival like Food, water and, etc.

For example:

Everyone thinks about Alternative Energy as the messiah of the earth, it will free us from the pollution, but let's take solar collectors - they are really hard to utilize https://www.theverge.com/2018/10/25/18018820/solar-panel-waste-chemicals-energy-environment-recycling, of course, it is an old article, but still it has a point, that it creates other problems, which needs solving.

I don't know if electric cars possess the same threat with their batteries. But I would not state that it is essential for our survival.

I’m thinking about making the jump to an electric car sometime next year. I had originally hoped to hold out for Dyson’s creation but read they are no longer going forward with their plans to build an electric car. I think I’ll likely get a Tesla as a result, but want to see what their truck and suv models look like first. I think if Tesla can live up to it’s promise of a self driving car by next summer, it will be a real game changer.

I hope down the line (rather sooner than later actually) most Cars will be electronic.

Hey buddies,

I say Subaru Turbo Diesel is best. Wrruum! Psiuuh!  That`s why im talking about BCH ASIC hashing 14,6 Ph/s 

I meant to say about extinction of humanity in less than 100 years.

Of course it will be useful for the future. The future needs more clean energy
Also these cars will save a lot of energy

Of course they are useful and extremely necessary in the future. Because we pollute nature with oil waste.
Only until prices fall significantly, these will be cars for rich people.

Why do engineers not want to develop water engines when people come to the decision that it is environmentally safe and useful...

The Ed Gray electric motor is basically simple. It has 3 armature arms, and two stator windings, similar to a starter motor on a car. The difference is that the windings are for very high voltage - as high as 50,000 volts.

Electricity is sent to both, the armature arms and stators at just the time that they pass each other. The high voltage is directed so that the face of the stator, and the armature arm passing it, both suddenly have the same magnetic field, north or south.

When this happens, there is a repulsion between the arm and the stator, causing the motor to turn. The high voltage electricity acts only for an instant, and is best produced by a spark to increase its force.

Since the electricity only acts for an instant, very little electricity is used. Since it is high voltage (low amperage), there is a lot of force produced.

At times Ed Gray believed that this motor form produced over unity power. Google "Ed Gray motor."

100 years?  I bet you we see a huge jump in starvation in a little as a couple years. Our crops are already failing.

Some scientists believe the modern electric car, with it's large battery, wi never go mainstream.   Solar power improvements will decrease battery needs.  Of course, there will always be a market for vehicles that need more power or operate when it's not sunny.

Of course its Tesla right now but most other companies were working on it and yes electric cars will be the future and by 2030 electric cars will replace half of current technology cars but not sure it is going to help for the survival of humanity.We have lot other risks like climate changes which could change the entire world in less than 100 years.

^ I found and read this article https://www.energysage.com/electric-vehicles/buyers-guide/top-ev-companies/. this article writes about the list of car companies that are developing electric cars.

Do you think that electric cars are useful for the future and the survival of humanity on earth? Electric cars are increasingly in the mood and are pointing towards mass adoption, here we can discuss about:
