Hybrid World Rally Cars

[itix]

Ok, for anyone that knows anything about electrics... The batteries would short circuit and burn. They'd have to be in an explosion safe cell as lithium burns when over heated.

For the people handling the car it would pose little to no risk as electricity generally takes the shortest route between positive and negative which means though the body work, through a cable or anything that doesn't have the thousands of ohms a human being has.

Humans have to be the only conductor between positive and negative to conduct... It is still surprising that so few actually know this.

The major hazard would be short circuit and battery explosion and for that there would have to be some form of protective case to the batteries (preferably water proof).

Hybrid systems are not more dangerous in road going version than they are in motorsport version.

With increasing use of hybrid technologies in all of the top levels of FIA motorsports, it is inevitable that hybrid technology will be coming to the World Rally Championship in the future.

No doubt. Just this week at Paris COP, Germany (and others) took the major step to get 0 emissions on all new cars before 2050. http://zevalliance.org/content/cop21-2050-announcement

2017 wrc regs will be used till the end of 2019. It'll be hard for FIA to keep alternative energy technologies away from WRC much longer than that.

The batteries will burn if short circuit happens soon. if not humans in the water with electricity will still be in danger, and water has more electrical resistance than human body, so?

So we have nice emissions of cars in our rich world and we don't care how the batteries are made in China and Korea.

We try to make the emission of cars smaller but we encourage the growth of car industry to ridiculous levels because it's good for our economy.

We create more and more complicated cars with very short livecycle but we pretend that buying a new car every five years is good for ecology.

We claim how we care about environment but we create lots of obstacles for second or third hand use of such cars to enlarge production.

We like to show how our factories and power plants are ecologic but we don't care that most of the sub-suppliers make their parts in China, India, Indonesia etc. where nobody cares about ecology.

We care about emissions of cars but in the same time we spent billions to promote diesels in passengers car about which everybody knows they are a lot worse for ecology than petrol cars.

We speak about cars emission but we don't care much about airplanes or ships.

We like to claim how we enhance ecological aspects of the traffic but we don't speak about the level of completely unnecessary transportation of goods which can be produced and spent on local basis. We created a colossal nonsense called subsidies which leads to insane transport of agricultural goods from place to place for thousands of kilometers. Than we created just-in-time ideology which again creates incredible traffic.

We can continue for a long time but I don't see anything ecological in all those ecological plans as nobody cares about basic things. It's like fighting a well known arsonist by buing better equipment for the firebrigade.

and water has more electrical resistance than human body, so?

You hit the nail here.

Water does not have more resistance than the human body, where ever did you read that?

Considering the broad "cable area" the water constitutes, electricity will not travel through the human body. The resistance is far less in water and the path for the electricity to travel through water is far shorter. Maybe you will feel a slight tickle but that is about it.

You have all sorts of ignition coils and other high voltage circuits in a car already and people aren't burnt to a crisp by regular car batteries either so why would they by hybrid batteries?
(try shorting the terminals with a spanner if you consider a regular battery weak... Ok actually don't because you can cause a regular battery to explode as well but...)

People have no concept of why regular electricity in the house pass through them... All electricity in modern grid nets is returned through the earth which is one gigantic conductor. If you hold something that want to return to the source through earth and stand on earth, you will be the conductor.

If you hold an iron bar and it touches a live source while connected to earth, you'll get burns on your hand due to hot iron and maybe a small tickle.

This is not difficult... Electricity follows the path of least resistance... And that is Not the human body. Skin is a pretty good isolator.

Water does not have more resistance than the human body

of course it does. water has much simpler and less electricity conductive structure, like lack of metal ions for one.

Also, Mirek has a lot of points in this post...

Society is moving towards "ecological" things but totally without ecological life cycles.

Still, dear Mirek, you are wrong about nothing being done about ships and planes. There is plenty done in both fields.

CO2 is not the worst emission with ships. They have NOx and SOx emissions far worse than cars due to the fuel they use and the slow speed of the engines. That's why loads of time and resources are put down on developing ways to combat this. I can go on for hours about this as this is my field of work... Should you be interested.
Regardless... The car will at some point be too expensive for the common man to run on standard fuels ad we know them today. I am 100% convinced that the car of the future will be powered from the grid, like most other personal appliances.

I don't like it but oil is running out and fossil fuels won't sustain personal transportation much longer.

I know this because I used to work in an industry that found oil, and I now work in an industry that ship oil (on a ship... You know, those that do nothing about their emissions).

There are lot of alternatives to fossil fuels, why are you so sure it'll be from the grid? Aren't electric plants also big polluter?

You forgot to say that we talk about electric car to be ecological but how do we take that electric energy? Most from carbon, gas, oil etc... Lithium himself is not renewable and will finish as well.
The point is that beside avoid fossils we should consume less energy, but the word "less" is again interest of who's there in Paris.
Look at them, they're the same doing wars from oil for decades, and now are talking about 0 emissions cars... Pathetic.
Sorry for OT...
