And i questioned your technical knowledge on this subject.
You and Morishta are the ones throwing out bull**** claims with no evidence. I am simply asking for your evidence, while providing my opinion. Case in point:

Probably should exchange complex for easy. Obviously gas cars are more complex, but they are easier to build.
Proof of this? Proof of Tesla's "moat"??

If the problem of cooling batteries was that easy then why isnt it solved yet by other car companies. And why do they keep releasing these crappy overpriced hybrid cars? Why isnt BMW simply postponing for a year, and then releasing a 300 mile range full eletric bmw?
Why did Microsoft design a working, simple, intuitive tablet, comparable to the iPad, in 2009, and then scrap it?
Your premise seems to be that if other companies could technically do something (as yet unprofitable and with as yet an unproven market), they would. That Tesla is only company that can technically do this. That's a ******edly hand wavy premise, frankly.
If you think Tesla has come up with some ground breaking technology, rather than simply cleverly deciding to use a one-off seriously under priced oversupply of an aging batteries on fully depreciated manufacturing equipment (and hence artificially cheap), then tell me what this amazing ground breaking technology is that others can't do, and I will eat humble pie.

And by large demand, i meant if you look at the price of the car. Porsche sells 130k cars a year, and they make a profit right? I seriously doubt there isnt that much demand for the Tesla S once they manage to fully realize production facilities. You also forget they have 20% gross margins, and they just need to scale up.
You say 20% gross margin like it's a good thing. Given the ongoing capex costs, it's not. And scale up to what? They're spending huge amounts of capex for what, exactly? If you read the article below, cheap batteries top out well below 100K cars. Then what? Pray?

And where do you get there will be a long term shortage of batteries? There is a short term shortage, but i cannot find any good source why this will be a long term problem. ANd please no vague statements.
Cost is the reason this will be a long term problem. You aren't looking too hard if you can't find any source on battery availability:
Putting Tesla Motor's Gargantuan Battery Supply Problem Into Perspective
Is a good summary. The key point:
Quote:
Manufacturing technology for 18650 cells has been fully optimized over the last two decades and the industry has finally reached a point where raw materials account for over 75% of cell costs, so future savings are highly unlikely.
What happens when cars start sucking up a substantial percentage of raw materials? Hint: the cost of the raw material goes up. What happen when you need to build new plants and can no longer rely on fully depreciated assets for production? Hint: the cost of the end product goes up a huge amount.

to quote henry ford here:
Seriously? No one quotes the failures, who say much the same thing.
Am I impressed with Tesla, the car, the company, its vision? Hugely. Do I think they're likely to be a large scale commercial success? Absolutely not. And you apparently agree:

At a net loss after capex. Sounds like a good proposition!
I claim it is unlikely to be harder than the engineering of a hybrid, with a battery, electric drive, plus a far more complex gasoline engine and all of its supporting components.

but they looked into it and figured that they couldnt make a good 300 mile range electric car.
You know this how?
Quote:
So thats why i think its not as easy as you claim it is.
Dumb reasoning, sir.

Other whise they would have said: 'oh we gotta cool some batteries? no problem, easy as pie! make it happen!' .
Cooling and monitoring batteries
is easy, dude. There are a large number of ways to monitor (temperature, pressure, electrical resistance). There are a large number of ways to cool (liquids, heat pipes, contact plates). There are a large number of ways to build for reliability (shielding, isolation, routing around bad cells, contact breakages via pyro, emergency venting + containment). This isn't space age engineering. It's well understood, and what isn't can be easily worked out. These are simple chemical reactions and current flows with extremely well understood characteristics. It's way simpler than building an internal combustion engine, let alone its support components.
Similarly, electric motors are possibly the most well understood and optimized devices in existence. They power everything from milliwatt devices through to hundred megawatt devices use for ship propulsion, pumping, etc. There are billions of them in existence.
That's all there is to the car. That plus some simple electronics, some decent drive train engineering, and some software, is the entire car. It is exactly this simplicity which allows Musk to even play the game with the high cost of batteries.
Is there complex engineering? Of course. Is it something other car manufacturers would have trouble doing? Absolutely not. It's a joke to suggest otherwise.
