so it's a fuse that costs $5k or $10k. is it made from 5oz-10oz of solid platinum? what am i missing here [1]? [1] http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3D...

Market segmentation. How do you get people to pay you another 10k? With a widget that is useless but has huge bragging value. People who don't care about 10k will spend it on this, and those who do care will have no different lives.

Does it cause it to go to plaid?

Aparently the new Roadster will. [1] [1] http://techcrunch.com/2015/07/17/surprise-tesla-is-working-o...

I assume that means awd for the new roadster; Otherwise I don't see how they could do tires.

Tesla's seems to be beating a dead horse! Don't get me wrong; I love what Tesla does but making a faster production car seems to be an answer to the critics who I think have already taken home the message that the electric car is as fast as the best IC car! I think what they should address is getting out the affordable Model 3 as fast to the market as they can. They may loose the game if the incumbents beat them to i…

> I think what they should address is getting out the affordable Model 3 as fast to the market as they can.

I agree, but I doubt this project took any manpower or resources away from the Model 3. If anything, it'll generate some extra cash to help with their R&D.

Should that happen, my guess is that they would be quite happy to sell their batteries to everyone else.

And I bet everyone else would be quite happy to buy them rather than setting up their own factories.

Didn't Tesla already give away their battery intellectual property or similar? If they did why wouldn't these other companies not just produce it themselves to cut Tesla out?

What you are missing is that it's a 1500A fuse.

Wow is that 1500A with DC current? Wouldn't there be a big magnetic field generated when so much power is pulled through the wires/bus bars from the battery? Would be kinda funny to do an insane mode launch and your pocket change flys out of your pocket and sticks to the floor.

Perhaps this is a side-effect of all of the R&D that's going into developing other cars and the drive-train for the Model 3?

At high levels of current it takes pretty drastic measures to break the circuit. Even if the conductor melts away you can still have arcing, turning the air into plasma and a replacement conductor. Kind of nuts that they had to account for that in a car .

Kind of awesome, I think you mean.

What a fantastic read! I wonder if they get any tech or materials from SpaceX?

Well, SpaceX uses inconel. They also must have a quite good understanding of pyrotechnics, as they need to use that in a lot of places, eg. stage separation.

So I'd say yes, at least on the tech transfer part.
