Tesla - Pimping Elon's Ride?


#2147

I flip flop between Musk being a Genius (The first time I saw the video of his spaceX rocket landing vertically I was awe struck, I shared it with everyone who would let me) a charlatan (hyperloop/car sled/monorail thing) or a mentaller (The Thai cave incident).
However, that video basically says that batteries have crap power to weight ratio compared to an ICE. He never proves that Tesla batteries are nonsense compared to other batteries though.


#2148

At the end he complains about click bait but he’s no better himself

His biggest mistake was to compare the weight of an EV battery with an empty or full fuel tank, he will understand things better if he compares an EV battery with the weight of his car engine + transmission + fuel tank

But its not all bad, he’s on the right track when it comes to Hydrogen

A new battery technology that will suck less than Tesla’s current batteries.

(Co-)Founder of PayPal, Tesla Motors & SpaceX.
And of course starting off with Zip2, which he sold for a third of a billion.

He’s most definitely parked in genius territory.

I’d hazard a guess and say recreational ( and perhaps some non-recreational) drug use explains his otherwise erratic behaviour.
However, given the unbelievable mental pressure he puts himself under, it’s not something I’d hold against him.

It looks like the bug fix for the Tesla’s swerving into lane separators gets lost in some updates.

Sales may be struggling.

The Tesla Model 3 News Is Bad – the Model S and Model X News Is Worse

The Tesla Model 3’s growth is stalling out, while Model S and Model X demand has fallen off a cliff.

It’s Friday :icon_biggrin: Enjoy!

Bad news for Tesla and EVs in general – making the battery alone causes up to 100g CO2 per kilometre over its lifetime. Add the CO2 associated with electricity generation and EVs produce more CO2 than diesels, according to a German study. Natural gas powered cars would use two thirds less.


#2157

The CO2 estimates may or may not be realistic, but they can never escape from the fact that in an urban environment (where most vehicles are driven) they are non polluting and their use will ensure the air at street level is far cleaner than it is at present.

Funded by someone with hydrogen power interests perhaps?


#2158

The numbers used in that study are pure BS, they are putting their thumb on the scales in a really obvious way

eg they assume that an EV battery will only last for 150K KM, we know this is wrong, the batteries in the gen 1 Leaf will last far longer than that, there are Teslas still going strong with close to half a million miles on the clock, and that’s in the Model S/X the cells in the Model 3 are known to be better

Plenty of people will believe it of course, there are still people who claim EVs need new batteries every 3 to 5 years

I just took a look at carzone.ie and there is a cheap Nissan Leaf with just under 200,000 KM on the clock, according to study above the car needs to be scrapped but I would bet its good for and another 100K KM no problem

They do seem to be taking liberties alright. Their CO2 estimates for battery production come from a Swedish paper – Romare & Dahllöf (2017): The Lifecycle Energy Consumption and Greenhouse Gas Emissions from Lithium-Ion Batteries. But that paper gives GHG numbers in kg CO2 per kWh of battery capacity, leaving it up to the authors of the German paper to pick a lifetime mileage to spread it across.

The operating numbers are then disimproved further by the amount of lignite burned in German electricity production, following their curtailment of 170 TWh per year due to shutdown of nukes.

It seems reasonable to say that the GHG implications of electric cars are far from negligible, but not as bad as this German paper is suggesting.


#2160

Yes your urban environments are cleaner and thats a good thing, but lets not loose sight of why we want to convert to electric - green house gasses.

For me it’s 95% of why we want an alternative to ICE. Ignoring sunk carbon costs from manufacture and disposal - charging EV’s from the grid where a high %age of base load and standby load means releasing sequestered carbon is not sustainable, maybe Musks next car will amphibious to cope with rising sea levels?

Regardless of Tesla’s own internal woes, I think this is the real killer for them – the world’s biggest carmaker with all of its mass production and mass market expertise is about to roll out models with equal or better range and charging performance …

It’s likely to be a lower price too, possibly in the high €20k’s after subsidies even in Ireland. I know which one I’d expect higher quality / better warranty from.

Tesla has completed its ~$240M all-stock acquisition of Maxwell Technologies! This could have huge implications for the company’s battery technology roadmap. Maxwell’s Dry Battery Electrodes offer a cheaper, more efficient and more sustainable way to produce lithium-ion cells. This means cheaper EVs, with more range! According to my research, this will put Tesla EVEN FURTHER ahead in battery technology, compared to legacy OEMs.
