A car that saves fuel by turning water into hydrogen.

Conference, conference, I am curious.

Well then, in a nutshell, today, the electric motor as a power unit is much less efficient than its weight and size by preventing internal combustion.

In addition, there is no difference in the level of pollution between an electric motor and an internal combustion engine, which is because both use the same energy source, only in one case they produce it at a distant power station and in another case you take some dinosaur juice with you.

By the way, someone who knows a little physics / chemistry / biology, is supposed to understand that it's just transferring energy from one form to another, that means you lose energy on something.

As for the future, you'll hear, I really do not know, if we move on to creating 100 percent green electricity, then maybe there's room for electric motors, and in that case, it's better to try to produce hydrogen for hydrogen engines that look much more promising, and again if you're talking about a future, You know, there's a situation in which we'll see some kind of nuclear reactor or something like that (yes yes I know that it was already discussed in the 50, something 3 fallout)

Although both the power station and the car work on fuel (in the first case it can also be gas and coal), but the mechanism is very, very different in configuration and scope so there is necessarily a correlation between efficiency. A power station can have a much higher efficiency, so even after offsetting the losses in the electric motor, it remains with a "gain".

Well then, in a nutshell, today, the electric motor as a power unit is much less efficient than its weight and size by preventing internal combustion.

Allow reference? If you include the batteries then you probably are right, but if you only take the drive unit (engine + chalk) the power-weight ratio of an electric motor, I think it should be much better - but not only because an electric motor does not require a standard gearbox. It already reduces weight by tens of kilograms, and even hundreds of heavy tools.

In addition, there is no difference in the level of pollution between an electric motor and an internal combustion engine, which is because both use the same energy source, only in one case they produce it at a distant power station and in another case you take some dinosaur juice with you. Very simplistic, and not really true, for two reasons:

1) The overall efficiency (refining and transmission of fuel and power generation) of a power plant is significantly higher than the efficiency of a typical internal combustion engine. Here is an example, although an old vehicle but will rely on the fact that there has been an improvement of 200% effectively since 95 ' http://www.electroauto.com/info/pollmyth.shtml.

In general when working on larger scale systems the greater the efficiency, the less there is overhead.

2) Concentration is the name of the game. If they discover new fuel and amazingly need to convert all cars, a matter of decades. If all the cars are electric, then you only have to convert power stations and you get the innovation within a few years. Electricity is a very successful form of energy. Any new fuel that is invented, any new method of producing electricity that will be discovered, will immediately get into your car.

By the way, someone who knows a little physics / chemistry / biology, is supposed to understand that it's just transferring energy from one form to another, that means you lose energy on something.

To propel a vehicle you must convert some energy into mechanical energy (there is no such thing as 'mechanical' fuel). Today, fuel is converted into a mechanic. With an electric motor, fuel will be converted to electricity, and then electricity to the mechanic. Ostensibly there is a waste here, but: the efficiency of an electric motor is very, very high, do not lose a lot there. Also, do not forget that in order to refuel, there is a fairly complex process (refining mainly) that the crude needs to go through, and there are full types for all sorts of cars. In general calculation, the extra conversion does not really cause you to lose anything in relation to the current situation.

As for the future, you'll hear, I really do not know, if we move on to creating 100 percent green electricity, then maybe there's room for electric motors, and in that case, it's better to try to produce hydrogen for hydrogen engines that look much more promising, and again if you're talking about a future, You know, there's a situation in which we'll see some kind of nuclear reactor or something like that (yes yes I know that it was already discussed in the 50, something 3 fallout)

A hydrogen engine is a combustion engine, only it is cleaner. If they learn to generate electricity from hydrogen efficiently, power stations will do it better than a vehicle just like the situation with oil today.

Other than hydrogen, it's explosive. I'm not sure you want to go around with a hydrogen tank in the vehicle (explosive, not flammable - much more dangerous than gasoline).

Beyond all the above, there are other advantages to an electric motor. The fact that you have 100% of the torque is already available from the 0 RPM is a huge advantage, there are almost no moving parts so the current maintenance is also Eden in relation to today The possibilities of planning with an electric motor are immeasurably greater than what a combustion engine allows - One on each wheel, is an interesting idea that has already been implemented in some models of models (models that work and drive 100%) - that's something you can not do with a combustion engine, and that's just the tip of the iceberg.

Currently there is only one drawback to the electric motor and this, again, the hoarding of electricity. It's a heavy and terrible thing right now. And will test all cell phone / netbook / laptop / electric toy / billboard cars and so'.

But because everything is electric then it is something that will have to be solved in one way or another. Whether it is better hoarding or very fast loading, better place replacement, in-drive charging and so on. The point is that the solution will be found, because there is no choice. And then the whole discussion of clean energy will become something that states are dealing with in power plants, rather than discussing each company She would have to investigate and solve herself. And it will be much easier, in my opinion.

I see no reason why in the future they will not switch to electric motors and refueling will actually replace energy cells at gas stations, that's what my understanding will be.

There will be cars that work on electric mazes, the "fueling" will be done by replacing "energy cells" (futuristic batteries) (and in the more distant future there will be units that will generate electricity within them).

There are many advantages to an electric motor ranging from function to recycling and manufacturing. (It consists of less flexible and more powerful)

And even in such a case it is better to try to produce hydrogen for hydrogen engines that look much more promising

And how exactly do hydrogen cars work? Hydrogen + Oxygen -> Fuel Cell -> Electricity -> Electric Motors

In any case the final paddle will be by electric motors, the power source can be batteries, hydrogen-oxygen fuel cell, futuristic capacitors etc.

Well then, in a nutshell, today, the electric motor as a power unit is much less efficient than its weight and size by preventing internal combustion.

In addition, there is no difference in the level of pollution between an electric motor and an internal combustion engine, which is because both use the same energy source, only in one case they produce it at a distant power station and in another case you take some dinosaur juice with you.

Electric motors today are very efficient (up to 95%), power / weight ratio of electric motors is excellent and reaches more than 10 hp per kg.

Subaru Impreza Turbo Enhanced "to the edge" can also give 500 hp and possibly more - from engine weighing including manifolds, transmissions, systems , Exhaust, etc. 300 Kg - barely 2 KW per kg This improved engine will last a few tens of thousands of kilometers before it will need a general renovation, the electric motor will last for a million km or more with minimal maintenance.

Moreover, electric motors are particularly efficient in traveling on an urban pattern (many seaweeds, long time crawling or standing) and their energy consumption in these situations is significantly lower than that of internal combustion engines.

Another advantage for cars with electric motors:

4 can be mounted in weak motors directly on the wheels instead of a central motor with mechanical power transmission to the four wheels. There is a great savings in weight, which is reflected in lower energy consumption.

For those interested in the subject, 2 lectures by Shay Agassi (one in English from 2010 and one in Hebrew from 2008, about an hour) on his project:

The lecture in English refers to the idea of ​​technological, entrepreneurial, business and political aspects. At first he talks a bit about his past, in any case a very interesting lecture, especially for those interested in business ventures.

In Hebrew, if I remember correctly, less relates to the political side.

Basically, this is the same lecture, more or less, in any case I recommend more about the lecture in English.

PS, I am aware that the discussion two months ago, but I have something interesting that I thought I should share :)

The future a little further away probably lies in fuel cells. (Hydrogen or methanol or something similar)

The thing is that today they are very expensive to produce, there is a significant decrease in performance over time, there are many other problems that we are dealing with

There are other solutions but the electric motor sounds very feasible in the short term.

A solar car can not develop enough energy because of the power of the area we have from solar energy.

The problem I see with such a motor is the loading time it takes

Maybe they'll find a solution, but I'm not a family waiting half an hour at a charging station to load the Mazda ...

There is also an idea that says that with the help of two atoms of hydrogen, it can be produced as 2500J, which is an insane amount, but science is still not there, and even if it is not as if it were called a bottle of mineral water and "fueling" The future and not only in these cars also as power and electricity programming

PS The engine of such a car would be included in an electric motor

The last comment reminds me of Mr. Fusion from the third part of "Back to the Future".

But seriously: I have been interested for some time in using SUPER CAPACITORS (or ULTRA CAPACITORS) instead of batteries - both in the automotive industry and in other fields , Etc.).

The problem as I understand it is the accumulation and release of energy too fast for continuous use as a tool for accumulation and use of electricity.

Is there a way to "slow" the sucking of tension from the receiver? Using electronic components to produce ashes between the power source (capacitor) and the voltage consumer?

It is enough that you find a capacitor that can store a huge amount of energy in a very short time and you have solved all the energy problems in the world with what is in the lightning .....

Every lightning absorbs a huge amount of electrical energy inside it
