electric cars

[mrmod]

Dan if a gas powered car hits a wall at 60 MPH there is a good probability that it will indeed burn. If a line or the tank is ruptured then morso. With todays cars and fuel injection the fuel systems are pressurized. A rupture in a high pressure fuel line creates a gas mist and alot more fumes which are actually what burns or explodes. The trick is to keep the fuel in an enclosed space where it can not turn to that fume or invisable gasious state that makes it flamable.

You are right (but i was talking about petrol and not gas). None the less if gas is pressurised it is even more dangerous (flammable is even worse). Gas is very different as it can escape better than a liquid.Hydrogen is dangerous in an internal combustion engine but a car that electrolyses water in order to create energy sounds much safer.

I see we have a bit of a language barrior bud. When I used the word gas I ment that stuff you get out of the gas pump at the gas station. I think you call it Petrol....liquid gas. The other type at the pumps here is Deisle fuel which does not explode or burn like regular car gas or petrol does. It has a far higher flash point.
When you talk about regular every day car gas or petrol it is not the gas in it's liquid form that readily burns, it's the fumes or the invisable gas that it turns into when it is left exposed to the air. Thats why when you are refueling your car at a petrol station you are supposed to shut your engine off,turn your cell phone off and put out your ciggeretts as these three items all have an ignition source for gas vapours.
When your car hits that wall at 60 MPH it comes to a sudden stop, everything under the hood is hot including the exhaust system. Electrical components may well be shorting and causing sparks, Gas line ruptures under pressure and the fuel vapours move forward at a rapid pace like everything else in a sudden stop at that speed. They come into contact with a heat source hot enough to ignite and there you have it.
You have to remember also that there are safty measures in place to try to stop this from happening. The problem is that in order for the car manufacturers to build new cars and increase fuel miliage while maintaining profits they had to reduce safty standards which is something you are not made aware of. Those crash test safty standerds we all know about and relate our safty to....well they are preformed at 15 kilometers per hour, thats around 9 MPH.

Aaaa i get you. Ok I admit defeat, you proved me wrong :rolleyes:. But crashes involving cars don't often involve explosions as that would be far too dangerous.


But euroncap (source) do their tests at 40 mph (front impact) and theyre the official testers in the EU. leepy:

I think electric are safer but anything involving speed can't be 100% safe.

Ok, so they are at 40MPH there, and I am not tring to prove anyone wrong but what is the speed limit on your highways?
Ours here are anywheres from 90 KPH to 110 KPH so where does any safty factor then come into play?
Then take into account that it is rare to find anyone traveling at the speed limit here, then take into account that most crashes on highways involve moving objects comeing in their direction.
I guess the point that I am tring to make is that the safty requirements are nothing more than a shame created to assist in the sale of the car. Gets the cash out of your pocket faster thinking it is a safe product.

[mrmod]

National speed limit is 70mph maximum here (112.65408 km/h) so not much difference. 60 in single carriageway and 50 to 40 in some areas. Villages 20 mph max.

In here the speed limit is taken very seriously ( a few points and you lose your license) :o.

I wont deny that safety requirements are used as a sale point. But i would definitly rather have mediocre safety requirements than none at all

which ever car they end up using it will still have to pass safety standards.

whether it's hydrogen powered or electric, it will be an improvement on what we use now. for me the duel powered cars only extend the use of fossil fuels.

[srijantje]

. for me the duel powered cars only extend the use of fossil fuels.

well,that is the idea,isn't it?

yes. but "is it the right idea" should be the question. by doing so they don't have to be too innovative do they. we can all make petrol from old cooking fat should we wish too. we have enough reserves of fossil fuels to last a long time and thats what they want, revenue from fossil fuels for a long time. they don't want to lose that revenue to hydrogen or electricity collected from alternative resources.

[srijantje]

yes,exactly

[mrmod]

But as we use more and more and there's more of us then it is inevitable .

They should develop the electric car now before we run out of crude oil and start paying out the ear for a gallon of gas trying to get every last drop. Then there will be a shortage. Long lines at refill stations, Fights over a gallon of gas. All while the oil company says oh wait, there is just a few drops more we can suck out of the ground, we insist.

I recall a respected member of SB providing some information in SD&D on the subject of fossil fuel reserves. Reserves he said and provided backup for what he was saying only talks about how much we have out of the ground and in reserve or something to that effect and that the total inground not taped yet reserves are estimated at enough to supply world needs at todays consumption with a factor added in to allow for increased usage projections that will last for the next 30 million years. I was shocked when i read the the material that he supplied to back up what he said. Now the number 30 million is low on my part as i think it was alot more than that. Can't remember who posted it but it was in a thread about it and i don't really have the time to look for it but i found myself asking...what bloody shortage?

a million year or a billion. all we're doing is unlocking stored co2 and choking ourselves. what he didn't say that to get most of it out we have to kill a lot of species. there's a lot there but the stuff that comes out of the ground with ease isn't as much as you think. the oil companies tell us we have to charge more in order to explore new ways to get at it that are financially viable. i's sooner see my tax dollar go to something that won't choke me to death and something that wont choke my grandkids to death.
