Tesla unveils new solar roofs

braindrain said:
Well yes after having a history of not being able to make the goals you claim a good salesman which is what Musk is is going to try and spin that history in a positive light. The difference is you seem to believe every word he says.
And no spin is going to change the fact that he has repeatedly made promises that his company falls short of.

Oh and here is an article dated March of 2009 where it was known that the 2012 model S would be $49,900 after rebate.

He never stated $50,000 without tax rebate, that is just fact.

"In order for us to be confident of achieving volume production of Model 3 by late 2017, we actually have to set a date of mid-2017 and really hold people's feet to the fire, internally and externally," Musk said on the call.

It’s an odd admission from Musk—essentially admitting that he sets fake deadlines with the assumption that there will be some level of failure along the way. Tesla deadlines aren't meant to be met, Musk says: they just pressure employees

I don't simply make excuses.

And he never said that only some people would be able to buy the car at that price either. Setting a price that has to rely on varying state and federal rebates that only some people will qualify for is not what an objective person would claim is the actual price of the car.

Did he say only some people would be able to buy the car at that price or that he was needing the help of the government to met his goal.
This is a perfect example of what I am talking about. It shows the mental bending over backwards you are doing to support him. If any person couldn't walk into a dealer and lay down a 50000 and buy the car outright with out help from both the varying state and federal government then objectively he didn't met that goal. Your bias is simply blinding you to that fact.
 
Now let's see if braindrain is biased. I have shown his examples of my bias as completely wrong. Will he admit it, or continue down this path.
 
Oh he posted while I was writing. He continued down the path as expected. The one who really is biased.

You have shown no such thing. The only thing you have shown is that you are apparently willing to believe every word that comes out of Musks mouth.

That's fine man. We all have our own biases. Apparently this one just happens to be yours.

You already admitted that not everyone will qualify for those rebates so how exactly is the using the rebates an honest description of the starting price of the car if not everyone can buy it for that.

Look it's rather obvious you are so caught up in your love affair nothing is going to change your mind. And I really don't care that much as like I said I am overall rather supportive of Musks efforts. Just not a nut swinger like some.

Have a nice day.
 
Tesla is creating gigafactories where raw materials come in one end and the finished product comes out the other end. The factory space will be fully optimized and designed like they would a machine, and much if not all fully automated with some of the world's best robotic engineers constantly innovating making the automation more and more efficient.

This is just a guess and very well could be wrong, but I am thinking three different type gigafactories being created 1/ An auto/battery gigafactory, 2/ a solely battery with grid, business, and home batteries, and 3/solar gigafactories that manufacture solar panels and shingles. https://photos.google.com/album/AF1QipOU1GPd4-ypVkednTuI0Qw67f9gKAcBomfERbzD

The article left off the most important step, Statistical Process Control!
SPC is what allowed the semiconductor industry to produce an unending supply of processors and memory, at ever cheaper prices.
The way it works is that the piece is examined at each step of the process, those pieces falling outside
of the statistical norms are culled from production, so the remaining steps need not be performed on bad product.

It sort of hints at it here: "At Tesla, it is critical to build as much as possible completely by robots. The Tesla cars are designed to be built with millimeter accuracy and to stay in tolerance by measuring them constantly so they never manufacture something out of specification."

Rumor new Tesla superchargers will charge the cars in a few seconds, faster than gas vehicles at the pump. That will ease range anxiety and eliminate 40 minute charge times.

It would be interesting to see what they are doing, Batteries store electrons as chemical changes,
these usually involve heat. driving that much chemical change that quickly, would cause a lot of heat.
Pushing batteries to the edge lately has resulted in pyrotechnical consequences.

By using supercapacitors instead of batteries, since they don't work on chemical reactions:

Supercapacitor breakthrough suggests EVs could charge in seconds but with a trade-off


The trade-off is in range, but not everyone needs to go 300 miles every trip.

Not necessarily. If he commercialized this technology , the energy density of the super-capacitors would almost be equivalent to the lithium ion batteries https://www.ncbi.nlm.nih.gov/pubmed/26818532

ON EDIT:

Another advancement that will potentially make an effect too (though it is not yet commericalized)

I think 47 W h kg is well below the better batteries, and many times below hydrocarbon fuels.
 
Tesla's estimate of $21.85 per square foot is based on a roof that's 35% solar tiles. CEO Elon Musk said most roofs would likely be around 40%, but depending on the home, it could be 70%.

To help put the cost into perspective, a Tesla Solar Roof for a home needing 3,000 square feet of roofing would cost more than $65,000 if 35% of the tiles were solar. According to Consumer Reports, a slate-tile roof for a home the same size would cost about $45,000, and an asphalt roof would be about $20,000.

So realistically this is going to be $70K v 20k or 50K for the solar part for those owning a McMansion. I suspect that the comparison looks a lot worse with normal sized houses because the percentage that needs to be solar goes way up but they dont give us that number...maybe 55K v 10k.

Thoughts?
 
Photo taken on Aug. 3, 2016 shows solar panels installed on a building of municipal government of Wenzhou, east China's Zhejiang Province. Covering 10,000 square meters in area, solar panels installed on buildings of the municipal government were put into use on Wednesday, which could generate electricity of 1.066 megawatts
