IMHO, there is a major problem with Tesla's batteries. Boeing has had issues with its lithium-ion batteries catching on fire. I wouldn't be surprised if more Teslas have the same issues in the future.
> IMHO, there is a major problem with Tesla's batteries.
Is this based on any kind of information, or just supposition stemming from the problems Boeing had (where, IIRC, Tesla offered to provide engineering assistance).
Well, the Chevy Volts' lithium ion batteries also have fire issues too. Not to mention overheated laptops with li-ion batteries that have caught on fire.
We're still waiting on any categorical information from you, other than your baseless fears stemming from problems with wholly different companies using similar technology.
You said "IMHO ..." and then asserted something with no evidence. So the only germane information is the quality of your opinions. I made no assessment of those opinions, I simply listed what I found, based on your posts, and asked for confirmation. If merely listing these things constitutes an ad hominem attack, then it says more about your opinions than it does about me.
My point (addressed incorrectly) stands. It makes less sense for me to answer "no" than for the person I was responding to to answer "no". If I was making a "straw man" then in what way was it straw? If I was misrepresenting his/her opinions, how so? Otherwise, if more-or-less accurately summarizing a person's positions is ad hominem then what does that say of those positions?
What are your qualifications with regards to battery chemistry and energy management system engineering? I ask only because you said this is your opinion.
Yes, but it seems that that may have the same issues themselves. Li-ion batteries are notorious for catching on fire. Yes, the sample size is too small to make a determination on Tesla but I suspect they may run into the same issues as Boeing as they sell more cars.
This is why people call you 'shill'. You aren't disagreeing, just using leading speculation. These are specifically not the same issues as Boeing, whose design Musk criticised for ability to produce 'domino effect' fires that get out of control very fast. That did not happen here.
Casting aspersions like 'li-ion are notorious' also stinks, much like the smell of gasoline before it (notoriously) explodes.
Ignoring the facts of the particular case whilst hugely generalising about the technology isn't a good foundation of debate.
OK, add every laptop manufacturer, cellphone manufacturer, and any variety of portable device manufacturer on the planet to that list, then, as lithium ion or polymer batteries are flammable no matter what.
I assume you have a suggestion as to how this could be remedied? Or, actually, looking at your comment history, I see you are also a climate change denialist.
So, which oil giant do you work for, for whom you are spreading FUD?

First of all, I absolutely agree with what you have to say about the danger of batteries as an energy storage source. Spot on. Good work.
But please, please, please, let's not throw around "paid shill" accusations here. Even if it may be true, it degrades the discourse of conversation for the entire community. Your comment's point was perfectly valid without that.
Yes, please accuse anyone who disagrees with you as being a paid shill. Saying that the IPCC has lowered estimates, which it has admitted in its report, is now climate change skepticism? Really?
"But lithium-ion batteries have raised concerns in other vehicles. Two years ago, battery fires broke out in three Chevrolet Volt plug-in hybrid cars after crash-testing."
"Two years ago, battery fires broke out in three Chevrolet Volt plug-in hybrid cars after crash-testing."
"After" being the operative word. They crashed the Volts for testing purposes and then left them sitting outside with a nearly full but damaged battery. THREE WEEKS LATER a fire started.
When testing gasoline powered cars it is standard procedure to empty the tank immediately after crashing it, if they had drained or removed the Volts' batteries in a similar fashion nothing would have happened.

Well damn, those sound like verified deathtraps!
Seriously, the fact that she had to reach back two years probably says enough. On the general note of battery safety in crashes, there have been several Tesla Roadster crashes (to be expected with that style of car) (http://www.wreckedexotics.com/tesla/), how many of them resulted in dangerous battery fires? Clearly these batteries do not present a serious safety concern.

Imagine that, structurally compromised systems not disposed of properly are dangerous. That says more about GM than it does the technology.
When I have batteries take damage (falls, shorts, the ever popular screwdriver through them) they are disposed of properly immediately. I also only use proper chargers and don't over charge my batteries. Guess what? I've never had a fire caused by the battery (I've had people plug in components in reverse and blow up the diodes a couple times). I've been working with various battery technologies on a near daily basis for the last 14 years without incident.
Disclaimers: I'm a robotics/electric vehicle enthusiast. I don't do this stuff as my day job any more. I formerly worked in a university research lab building H2 powered race cars.
