Thoughts on TESLA

Q 3 Earnings due out Nov. 7th or there about's. Stay tuned......

I have not had crow, but is it kind of like chicken?

Most likely, darker meat and tougher. Fried may not be good, but stewed is probably more edible.

No. I think it’s bitter.

FREQUENTLY ASKED QUESTIONS ABOUT CROWS

In my opinion, crow tastes just fine. It is similar to wild duck or any other wild bird with very dark meat. Crows have no white meat on them, as is true for most birds. (Whenever someone says something "tastes like chicken" remember that they're talking about the DARK meat of chicken, not the white.)

 

[NW-Bound]

Crows may be too small to eat. Ravens on the other hand are almost as large a chicken. They would make a good meal, I think.

On youtube, I saw several guys preparing crow breasts, and it looks red like duck breasts, and one guy said it tasted like duck.

We have some turkey buzzards around here that eat roadkill. They are pretty big (turkey size) and probably full of dark meat and muscle. Pretty ugly birds though.

I love it when a thread really goes off track.

 

[aja8888]

Somehow, we lost Oneil...he was keeping it on track!

 

[bobandsherry]

Somehow, we lost Oneil...he was keeping it on track!

He'll be back, just wait for another $20-30 increase in the stock. Heck, after seeing the resistance at $250 I snuck in and grabbed a few shares at $255. Now deciding on when to exit. It was purely a gamble with no intentions for holding long term. I guess if Tesla hits $330 again it will pay for my order of crow I'll be out before that.

 

[NW-Bound]

Well, don't you get tired of badmouthing Musk day in, day out? The poor guy has not been tweeting, has he?

So, until something exciting happens, like the next Tesla earning report, we can keep the thread alive with some side discussions. It's more fun that way. When something relevant comes up, we will get back on topic.

Deal?

So I did an image search for "Tesla" and "roadkill" and this was one of the hits:

It's my guess that Tesla will be dead long before the internal combustion engine is.

+1. Many large industrial applications for electric motors like locomotives and ore trucks use Diesel engines to run generators that charge batteries to run the motors.

How about ocean going vessels and aircraft? Nowhere to "plug in" in those places. Then there is emergency response equipment like fire trucks, helicopters, military vehicles, etc.

Electric vehicles will propagate and become more common, and they will have their place, but there will continue to be ICE and turbine engines for a long time.

The neighbors 17 year old son got to drive around the block in a 1970 Chevelle with V-8 and manual transmission , 4 on the floor, headers, , etc.

You should of seen the look on his face. Far cry from the Hundai Santa fe he he has always driven.

I also had an interesting look on my face after I drove Dad's recently acquired '72 Chevelle he bought from a friend in 1980.

Turns out it was the basic model with no power steering or brakes. At the first brake and steering event, you should have seen the look on my face!

I actually learned to love that car. I also built up some good calf muscles. Nothing like pushing that hydraulic oil down to the cylinders all by yourself.

And for those who might not be aware, a gas turbine (any combustion turbine, versus a steam turbine), is an Internal Combustion Engine (ICE).

I broke that out separately for those who don't understand the concept and wanted to make a point about "other than piston" engines.

I assumed you knew the difference from the context, but I just thought it might not be clear to others.

https://www.economist.com/leaders/2017/08/12/the-death-of-the-internal-combustion-engine.

I thought the Economist was better at real journalism than that. I was disappointed.

A few things I picked up on:

The internal combustion engine is the mightiest motor in history.

Steam turbines are the mightiest 'motors' by far (the context implies 'motor' and 'engine' are used interchangeable here). And it's not clear if by 'internal combustion engine', they mean ' internal combustion piston engine'. But I found:

The largest piston engine was ~ 109,000 HP. The largest gas turbine is 500,000 HP, and the largest steam turbine (external combustion)...

https://www.ge.com/reports/two-gian...ed-arabelle-head-for-the-english-countryside/

... the largest steam turbine ever built— ... A pair of them, each capable of producing 1,770 megawatts...
​

that's over 2 million HP! So the ICE is not the 'mightiest motor in history' by far - The Economist is off by a factor of ~ 2,000x (!) if the comparison is to ICE piston engines, or a factor of 4x if we include gas turbines (which are not used in any production automobile, if that was their point).

And then:

Compared with existing vehicles, electric cars are much simpler and have fewer parts; they are more like computers on wheels. That means they need fewer people to assemble them and fewer subsidiary systems from specialist suppliers.

Is that true? I found:

" The 85 kWh battery pack contains 7,104 lithium-ion battery cells"

​

Plus the cell packaging and temperature control components.

And if they are so simple to assemble, why:

https://www.wired.com/story/musk-model-3-tesla-production-delays-january/

Musk had predicted that by the end of the year, the Model 3 production line would be humming along, cranking out 5,000 cars per week. In a Wednesday letter to investors, the company pushed that target back to March 2018 ....

The feeble numbers can be traced back to the Nevada Gigafactory where Tesla builds batteries for the cars.
​

and another source:

It has now been confirmed by Tesla in their shareholder’s letter:

“To date, our primary production constraint has been in the battery module assembly line at Gigafactory 1, where cells are packaged into modules. Four modules are packaged into an aluminum case to form a Model 3 battery pack. The combined complexity of module design and its automated manufacturing process has taken this line longer to ramp than expected.
​

And of course, the obligatory reference to the EV as "zero-emission" which is BS. If they want to to say "zero-tailpipe-emission", it's at least defensible, but not so meaningful (other than from a very local pollution, NIMBY POV).

And "as electric cars become more efficient "... EVS are already very efficient in terms of turning the power from the socket to the wheels. There is really very little 'more' to be realized. It's just not very relevant at all. But it sounds good, right?

[Texas Proud]

EDR.... I have not read the article and might never do so...


But, the reference of mightiest engine might be in the common use of them... IOW, there are millions of cars with them out there... no so much with turbines... they keep the economy humming along....


I will admit that this is a stretch and if I read I would know it is just plain wrong... just wanted to throw it out...




But hey, what about the Saturn V rocket... https://www.quora.com/What-was-the-horsepower-and-torque-of-the-Saturn-V-rocket

So, assuming my math is correct (which is debatable), that's (1,746,000lb*8,800ft)/550=27,936,000hp per engine, and at that time (first stage burnout, four engines would be firing for a total of 111,744,000hp. Which is a meaningless number, which is why rockets are not generally rated in horsepower.

Rockets are external combustion engines. (or maybe not?... see follow up posts!)

[Totoro]

They are?

 

[ERD50]

They are?

Hmm, I thought so, but now I'm actually having trouble finding a clear distinction.

This ( https://www.sciencedaily.com/terms/rocket_engine.htm ) said 'most', not 'all':

"Most rocket engines are internal combustion engines...", so I'm not sure where the distinction lies. I was thinking that in something like a Saturn rocket, the combustion takes place outside the chamber, but I guess inside the nozzle? Is that internal or external?

Seems fuzzy, but at a minimum, I'd say my statement is too strong, I'll see if I can still edit...

I'm not sure what the technical distinction would be. It seems logical that if the combustion gases are also the working fluid, then it is an IC engine, but if the working fluid is something other than the combustion gases, it is external combustion. If that's right, then a "regular" rocket engine would be internal combustion, unless, for example, the combustion was being used to make steam which was then expelled to make thrust.
