A typical Petersen ploy... Focus on Tesla and try to spin it into a negative when it really is a positive. Lying by exclusion. Considering Tesla uses roughly 1/2 the Cobalt per kwhr compared to competitors, yeah, ummm I would say that they would be the LEAST affected by a cobalt shortage. I...

Maybe I was reading something that was misreported. i remember reading something about Powerwall V2 having double the energy density of the Powerwall version 1, and Powerwall V2 is supposed to be using the new 2170 cells. Also the 100 kwhr pack has an energy density of 8 lbs per kwhr, so...

Petersen is back, this time bashing the Tesla truck idea. He gets alot of things wrong again. 6 kwhr used to power a truck, yes, while true, he thinks a diesel engine is 100% efficient. Doesn't realize trucks don't constantly go up hill. An average truck gets 5 mpg and the ultra...

Considering Tesla uses LESS cobalt than almost every other EV on the market on a per kwhr basis, it would make them LESS impacted by a "cobalt nightmare" and actually give Tesla a competitive advantage. I see- Just throwing Tesla in there to get the clicks.

Petersen is still trying to beat down the Tesla. It's funny and sad at the same time. How many angles has he tried to attack Tesla? 1. Electrical grid 2. Life cycle assessments 3. Resource depletion 4. Finances (this can be broken down into like 10 separate sub-items) 5. That the early...

Yes, I was counting it as part of the base price (minus all the incentives first). Think your method makes better sense, If the fuel was removed $10 K over 36 months or $15 K over 36 months, the lease would be between $82 -$220 per month (makes no sense) It would be really interesting to see...

Just ran the calculations for the lease: The MSRP is 57500 cash or $499/month with $3600 down with free H2 up to $15 K of fuel and $13 K in rebates/credits... Bank gets the rebates and the fuel is already included. Subtract out the fuel and rebates (since they are baked into the price)...

In Petersens most recent article his unbridled zeal to attack Tesla and attack EVs in general made a case for investing in Tesla vs other EV technology. Think about it for a moment: He went on a rant about cobalt shortages, well guess what Tesla uses NCA which has a lower usage of cobalt than...

You know what I think would be funny; If someone could compile a list of Petersen predictions, denegrations against Tesla, dates and a one sentence thing to prove him wrong. I could giggle at that for hours.

Figure I would point out he's been relatively quite and not bashing Tesla in a while. It should be made known the amount of misinformation he spread, just in case he starts again. Guess he has no need to since his AXPW is crashing and crashing hard. If you had 100000 shares at 10 cents a...

It amazings me the ineptitude and false justification at S&P typically large companies are displaced by new entrants into the market. Someone needs to bone up on the Kodak case study, the GM case study, typewriter manufacturers, or even the buggy whip manufacturers. There is a phenomena...

If that graph is correct, even if you adjust for transmission losses just a rough eyeball of 220 lbs per MWH yield an equivalent emissions of 260 mpg car. Even if you use a plain old regular coal plant the emissions are equivalent to a 35 mpg car. Well, considering the Tesla is a sports...

Toyota is essentially screwed with fuel cells, at least in the US. What we have to do it look to the near future; First, you must build the stations and then you must compete with both the price of the car and the cost of the fuel. Let us look at 2017; Tesla's generation 3 is going to...

I think if we really want to get at the crux of the FCV vs EV arguement; the ZEV credits must be analyzed. For starters the question comes up as to why fuel cells get 9 credits vs EVs getting a maximum of 7. Secondly the entire purpose of the ZEV credit is for lower emissions correct and...

While true it would put more oil in circulation, but at the same time the cartels may cut back production to counter act that (that is what I would do), forcing the price up more and somewhat screwing over the US. That crude is a royal pain to refine (Valero does a good job of taking that...

When I was in college, we visited a chemical plant and a few days before they had an accident where one of the tanks flipped and the valve got sheared off and went through the wall and damaged 3 cars in the parking lot.

Ok , off on a little tangent, but what if a hydrogen car hits road debris like the ones a few Tesla owners have hit? Or what if some crazy owner decides to take a round about at a high speed in a hydrogen car around 2 AM and crashes? Questions, questions.

More like the light wars between Edison and Rockefeller. Actually same things were said 100 years ago against electricity too (fires, hazardous, etc).

To put in bluntly Toyota got really, really lucky at least in the US when it came to the Prius. If you look at the "jumps" in gas prices, 2005 and 2007 the Prius also started to take off. Had gasoline prices stayed at 2004 levels the Prius would be a footnote in automotive history. Toyota...

There is no way to make the fuel cell vehicles for 1 million cars per year; unless we are no longer earth bound or a huge platinum bearing meteor shower starts and rages for the next 100 years. Essentially, current technology the FCV if using platinum requires 150 grams of it. Doesn't sound...

I think people need to realize that the keystone pipeline ships from Canada and ships all the way to the Texas coast. That is interesting to say the least. It would be much cheaper to convert preexisting plants closer to the keystone pipeline and decrease transportation and pumping costs...

While you cited safety for the Mercedes and how people in China ignore the safety features in the back seats (seat belts). I don't believe that is a valid argument since any safety feature, or most safety features can be over ridden. Same could be said for American drivers, I don't have my...

Doesn't Disneyworld have something like this put with pressure? I thought they had piezoelectric transducers hooked into the surface of the main entrance or something. Could also work for roads.

"And the electric car is a loser on the total energy efficiency scale today. A gasoline-powered car is probably 80 percent efficient and isn’t carrying a bunch of lithium batteries around." Wow... I mean wow An 80% efficient gasoline car, for a tesla sized car (a jag) would get the equivalent...

That is what bothers me. Trish Reagan tries to be them down Never answered the question. incurred by the dealership or factory- why not, financing, hazardous materials inside of it, big purchase- So what, you can buy a $40,000 TV no questions asked, but buying a $15000 car is a big deal...

I do think they are corrupting the intent of the law here. Lemon laws should be used if the car is "unworkable"; i.e. it leaves you stranded on the highway without any reason. If the biggest gripe is the door handles, that is a situation that is not worthy of a lemon law suit in my...

Here's some real good questions Did you have the doors "locked" when they handles were not extending? A video can be pretty easily doctored Also, I can very easily interfere with my FOB if I have it in the same pocket as my cell phone. Move the phone, and the car receives the FOB signal...

So this past weekend my father was talking to a guy who works for a Chevy dealership in NJ. Any rate: here's the the dealerships issues: Lack of service centers, selling for a lower price, and that you can only go 200 miles per charge and that the superchargers are in inconvenient areas. I...

ecarfan, it's based on the price of the car and the income survey from here. I think there was a survey on here that pegs the income of over 100 K (makes sense since a household making 40 K probably will not purchase a 100 K car). It trends to be more republican or moderate than lower...

So let me put this in persepctive Democrats already dislike Christie Now Newt ( a hard rightwing republican says Christie is incorrect), that means senior citizens will not like Christie Tesla owners dislike Christie (not bragging but they are the upper middle class and typcially vote...

SO here's something else to consider, remember road damage is axle wt^4 9 axle; 80,000 lbs of gas per tanker, by driving a Model S vs a regular car, you have only caused 2% of the damage of a regular car on the road due to tanker deliveries if the miles are the same (80 K/9)^4 *9...

There was something a few weeks after Tesla paid off the loan where Fox was touting them as a success, new auto company, then left out they got they loan. It was truly funny to see the "reporter" back track... He said the company made it without taking any government money then one of the...

Another ICE fire, taxi in the city with lots of witnesses Photos: Cab Fire on Rittenhouse Square | News | Philadelphia Magazine Did not EVEN make the local news! Little blurb in an online magazine.

The important aspect to consider is that for the refining portion, you can assume it is a black box and do inputs and outputs. As long as you know the outputs per barrel and the energy in each of those outputs, it is a trivial calculation. I had a professor, smart guy, he used to do energy...

If you really want to get to the bottom of it, there is a basic chemical engineering principle called an energy balance. Essentially mass* energy per unit mass = X outputs mass* energy units =y Y/X = your energy efficiency in a barrel of oil contains 1.7 MWH of energy...

Actually there are scenarios were the use of an EV using baseload charging can actually decrease the grid emissions. Try to follow my logic. We know that energy consumption follows a graph where most usage comes during the day. This is a mix of baseload power, peak power and solar We...

He is so blinded by his hatred of EVs he can't make a logical decision. At least some people have rescinded, even Fox news supports Tesla now, even after the big Palin/Romney flap.

Not to tip my hand, but I'm currently analyzing the analysts to determine which analysts make the right call regarding Tesla stock. So I took articles from 2 years ago until today: Predefined setpoints, 1 month, 3 months, 6 months, 1 yr, and 2 yrs. Then i took the price the article was...

I agree, the NHTSA needs to concern themselves with cars that have caused serious injuries and fatalties to the occupants. It's sad to say, but there has to be a severity vs occurance. i.e. 2 fires that cause property damage over a recognized rare occurance that involves human interaction...

Well that capital expenditure is a one time cost. Spread out over a long period of time the capital expenditure per cell decreases. Kind of like saying that building a new refinery cost so many billions, and produces so many gallons, then only counting one years production.

Yep, I just checked, I can get the cells for 2.5 a pop online, not $4. He also thinks the battery costs 24 K to make and that the Gen III will have the same capacity has a Model S. not even close. Plus he forgets this little thing called capitalism. Markets will step up to the plate if...

Petersen is at it again: citing $4 per cell and saying that Panasonic is taking a loss on the cells.. yada yada, yada. BTW- great job capitalist oppressor!

I think it may be a little of both. For instance, I corrected him and showed him how to do a LCA, did he use it, did he even state in his paper that his stuff could be wrong? Nope. Presenting something as fact, when you extrapolate, and fail to follow the ISO standards is dishonest. That...

Except Tesla has that goo that protects if there is a failure in one battery. I likened it more to sickness and the immune system. a healthy person recovers from the flu, but throw in more and more diseases, it makes the immune system overload. Pulverizing batteries is like giving Krusty O's...

Thank you everyone. This is very helpful and actually shows that baseload, the more efficient energy generation is used to charge the EVs, and if this trend continues it is foreseeable that our energy consumption could get rid of peaker energy (less energy efficient)

I appreciate any help so I can determine the usage and charging patterns for Model S owners. If it falls within a two of those time frames, pick the one in which most charging occurs If you charge multiple times a day, pick the one in which most of your charging occurs.

I called him out again. His response was that Musk should release an LCA so he doesn't have to make up stuff from other LCAs. My point is that if you are a professor, and someone gives you a completely wrong answer, and then says, well, if person XYZ had done his work, and I had copied it...

Johnny boy poked his head into the second rebuttal article and tried to defend his work. Bring a stick to a gun fight. I like how he tried to say based on the energy usage, the tax payers are on the hook for over $2 per gallon, and that it's only saving 3,000 gallons over 180,000 miles...

Another Petersen article out today with LCA stuff. The LCA that he cited was decent, but then he goes and bastardizes it to meet his needs. (I don't like the soft science of including economics in with hard science though in the LCA- that shouldn't be in there) Why does he insist on...

Here's another way to think about it. There is a certain base load, that has to be running all the time regardless ( some plants get taken off line due to seasonal variability) Now you have day time usage. Of everyone had solar, and we could run off solar exclusively, then you switch and...
