The weather is not melting cars. But there was a big fire in Tucson and the heat from the fire melted plastic parts on a bunch of cars in the parking lot. The pictures in this article fairly clearly match the cars, parking lot, and background building in the picture you attached.
So, are cars in Arizona melting in the heat? A few that were unfortunately ...
tl;dr: The claimed range is 50% higher than the worst assumptions for battery production, and 500% higher than the best assumptions. But it's not an apples to apples comparison.
Carbon emissions from battery production
The range of values estimated for emissions from battery production varies widely in the literature:
In an answer on Sustainability.SE I ...
I focused on the US for this answer. An apology does not automatically lead to the party being found guilty:
The apology may not be admissible in court (but the laws are complicated, as usual).
When it is admissible, the judge or jury will be deciding if anyone is guilty or not. In many cases, an apology is not seen as strong enough evidence on its own.
It's a PR stunt, and a very bad one at that. There are several debunkings out there, e.g. from ElecTrek, or (the best IMHO) from DÆrik @ YouTube.
Strongest points made by DÆrik:
The press release by PromoBot claims that the driver has "put the car in self-driving mode". Such a mode does not exist in available Tesla models.
The Tesla "autopilot" would not ...
This is something of an urban myth - the drying time gains were made by using oven-dried enamel coatings on the parts that could withstand the required curing temperatures.
The so-called "baked enamel" coating used by Ford was called "Japan Black" (produced for Ford by APV Engineered Coatings) - this is an asphalt-based enamel coating which is applied to ...
Ford has said that the F150 pickup has 150 million lines of code.
According to the New York Times:
Twenty years ago, cars had, on average, one million lines of code. The General Motors 2010 Chevrolet Volt had about 10 million lines of code — more than an F-35 fighter jet. Today, an average car has more than 100 million lines of code.
So, even if ...
In addition to all the other great answers there is one very important fact that's always ignored in these comparisons (Google translation, lightly corrected by me):
The total emissions of petrol and diesel are sugarcoated in this example.
For oil extraction, refinery and transport on tankers, in pipelines and trucks 44 kWh of energy was used for ...
tl;dr: No. The claim is that there would need to be six times as much electric generation, but if all cars in 2019 had been electric, only 1.43 times (43%) more generation would have been needed to power them all. This was most likely within the capacity of the existing power system.

...but China only has 37% of the world's reserves
Michael Karnerfors has provided evidence that China produces 95% of the world's rare earth elements. However, China does not hold that much of the world's reserves of such metals.
The US Geological Survey mineral commodity summary for 2017 for rare earths gives China's 2016 rare earth's production at 105,...
The car does not run on water. The article you link says quite clearly that "The car runs on acetylene gas".
Acetylene is an explosive gas that is used for welding, and before the invention of electric lamps it was used for lighting. It is produced from the reaction of calcium carbide and water, as follows:
CaC2 + 2H2O → Ca(OH)2 + C2H2
The problem is ...
LOC is a particularly bad metric, because it raises the question of what is a line of code. Do you include whitespace and comments? Compiler directives? Preprocessor definitions? How about lines containing only braces? Do you include makefiles or whatever scripts do the building? And in the end, does the number of LOC truly relate to the complexity of ...
I did some more research on this tonight, and was able to answer my own question, at least to some extent.
The conclusions seem to be:
For the world as a whole, this is a very unlikely claim.
For the United States of America in particular, this is likely true, at least for the deaths of Americans in wars since the country was founded. This is possibly the ...
A search on https://tineye.com led me to this tweet by @AyeElleJay with the caption "Slimmmmm! Arizona weather real different 😩" against that image.
Replies to the tweet questioned its validity, and a user named @TheMutHouse replied "this is from a recent fire in tucson, the neighboring apartment buildings cars were melted."
I'm not sure if it's the ...
If I'd spent 30 seconds looking instead of 2 minutes posting here I'd have found the answer on Snopes. Its an old legend dating back to at least 1978.
Origins: This legend surfaced in print in 1978, but an anecdotal sighting places it even earlier than that, in 1971. Though its exact beginnings can’t be pinpointed, according to Brunvand:
The June ...
And the mechanical friction caused by the alternator does not depend on whether electricity is being needed or not.
In other words, when energy is not needed it is wasted
Wrong. The electrical energy produced by the alternator is not the result of mechanical friction but of magnetic force on top of the (very small amount of) friction, which ...
I hope this helps...
Built in Germany from 1961 to 1968, the Amphicar is the only civilian amphibious passenger automobile ever to be mass produced. A total of 3,878 vehicles were produced in four colors: Beach White, Regatta Red, Fjord Green (Aqua), and Lagoon Blue--the color of ...
At least in Canada, no.
Canada actually has an "Apology Act" that essentially says that you can apologize for something and that apology is not to be considered a confession, admission of fault/guilt.
Apology Act, 2009
S.O. 2009, CHAPTER 3
Consolidation Period: From April 23, 2009 to the e-Laws currency date.
No, about 40 to 60%
Internal Combustion Engine (ICE) vehicles currently use 146 billion gallons of gasoline used each year annually. A gallon of gasoline represents about 33 kWh of energy. So all the ICE vehicles are burning about 4.8 million gigawatt-hours in their tanks.
The US currently produces about 4.2 million gWh of electricity annually.
The claim ...
From Cornell University News:
An acre of U.S. corn yields about 7,110 pounds of corn for processing into 328 gallons of ethanol.
That's 3,225 kg and 1241 liters.
Let's assume that the "large SUV" has a twenty gallon (76 litre) tank. So that's 7110 pounds divided by about 16. That comes out to 433 pounds (196 kg) of corn.
According to a December 2013 article in USA Today, the XL1 cannot meet US safety rules.
The latest teaser: XL1. It's a spaceship-like, ultra-high-mpg, plug-in diesel-electric hybrid. VW used exotic, but obtainable, materials and technologies to craft a mileage-above-all car able to get 261 mpg in European tests, equating, very roughly, to ...
Driving a jet ski for one hour will produce the equivalent amount of pollution as driving a new car 100,000 km.
This claim seems to be INCORRECT.
First, the claim appears to be credited to Stienstra (1998):
The state Air Resources Board is also considering taking statewide
action against personal watercraft, after a staff report said that two
While I don't know if this particular company is doing something useful or not, I can talk about what an aluminum battery could be used for in electric cars.
In general, electric cars use lithium ion batteries. The problem is that in order to get a decent range, you need a lot of batteries. From an engineering perspective, these batteries are heavy, which ...
IVL, the source of the 150 to 200 kilograms of CO2 figure, recently published a new study that ended up with a much lower estimate: 61-106kg per kWh of battery capacity, depending on the energy sources and efficiencies of different manufacturing plants. "[This] puts it much more in line with other studies."1
Reasons for the difference:
The new study ...
This is a thorny question, both because it is a politicized issue, and because the effects of cannabis use while driving are less well studied than the effects of alcohol, and appear to include a number of confounding factors.
Overall, my survey of the literature suggests that there are two questions, which have (surprisingly) different answers:
"Wars haven't killed all that many people," eh? I think you want this Wikipedia page on that topic. Simply summing all these estimates (using lower bounds where ranges appear) gives 344,998,537 as the death toll of this "very incomplete list of wars (an estimated 3,010 wars have taken place in recorded human history and 438 are recorded here)." Plenty of ...
Summary: Chevrolet explain that they took some effort to avoid actors, but further investigation found that some had appeared in the adverts.
The "Real People, Not Actors" is a ad campaign which is described as a focus-group type of ads undertaken by Chevrolet to capture honest reactions of real people which are uniformly positive about the Chevy vehicles. ...
There is no reason to doubt that Churchill explicitly mentioned Rolls-Royce in the context of the quote.
A Google Books search limited to books published before 1960 returns at least four publications that feature the Churchill quote including the Rolls-Royce reference:
Jackson, G. G. (1930). The world's aeroplanes and airships, p. 173.

Are there lots full of unsold cars? Yes
Are those cars being left to ruin? Almost certainly not.
Here is a much more reliable story about lots full of unsold cars, from Business Insider. However you should notice an important thing: it's from 2009 - when the most recent recession was just getting started, and car sales were plummetting.
The next thing to ...
This is the research paper in question.
The research paper was just released Nov 18th, 2017. Typically it takes some time for a proper peer review, and with a proper peer review, the next step for notable research papers is generally publication.
Compared to many other eye raising claims, this one has the form of an authentic claim.
The writers are ...
