EV drawbacks

One thing that does make me laugh is the alarming headlines like "it's the hottest day on record" etc
Well the "on record" or since records began is bit of a clue
How long have we kept temperature records? 150 -200 years maybe!
Not billions of years

That was shared a bit back Baz. Not only are you right, it’s worse…

Measurements began in the mid 1800s. At what many have proven was a historic LOW POINT in global temperatures when looked at over proper timescales.

Obviously, if you’re in a historic low point, the only way is up…

Oops I probably read it then forgot 😂😂😂 oh well I do remember having a good summer last year
This year not so good
 
They gave up on long range forecasting back in 2009.

Met Office admits ‘barbecue summer is off’

The Met Office officials refused to apologise today after admitting that the “barbecue summer” they had predicted was no longer likely.

As rain lashed down on most of Britain, a revised forecast was published suggesting that the weather in August would be changeable with more rain as well as sunny periods.

A Met spokeswoman insisted that updates were always made to long-range forecasts and explained that the earlier prediction had included June and July as well as August.

“’Barbecue summer’ was a phrase that we used to convey the fact that the weather was likely to be better than the last two years,” she said. “People have said to us, that I’ve spoken to, ‘I’ve had more barbecues this summer than in the last two years’.”


The revised forecast will come as an embarrassment to the Met Office who published a press release in April detailing news of a hot summer.


As for climate modelling, the climate is a chaotic system and chaos cannot be modelled.

Numbers limit how accurately digital computers model chaos

Digital computers use numbers based on flawed representations of real numbers, which may lead to inaccuracies when simulating the motion of molecules, weather systems and fluids, find UCL and Tufts University scientists.
www.ucl.ac.uk www.ucl.ac.uk

Professor Peter Coveney, Director of the UCL Centre for Computational Science and study co-author, said: “Our work shows that the behaviour of the chaotic dynamical systems is richer than any digital computer can capture. Chaos is more commonplace than many people may realise and even for very simple chaotic systems, numbers used by digital computers can lead to errors that are not obvious but can have a big impact. Ultimately, computers can’t simulate everything.”

So a pointless exercise.

Dropping like flies, because even CORPORATE WELFARE known as "subsidies" (the government pissing away tax dollars of working people like a drunken sailor) are not enough to resuscitate the stillborn EV disaster
 
Read the first and last sentence of this excellent chart from the local Orlando museum. They can’t hide the truth of long term natural cyclic warming & cooling.

Snapped this screen image of local news this morning, with what looks like a tesla model 3 burned out. This was part of a four home destroying fire that started in one homes garage. Unclear if this car was the ignition source but worrisome none the less.

Did a YouTube search yesterday on tesla fires and was amazed at how many results came back. Included a few news stories reporting on deaths of occupants, included one where it was concluded two people died from "thermal" effects, not the proceeding crash impact. Another of a mother and teenage daughter both killed after an impact with a tree at residential street speeds, with ensuing fire. Took firefighters many hours and about 100x more water to put out the vehicle compared to a gas car fire.

I don’t think you can put the fires out, especially with water. I think the idea of using so much water is to contain the situation whilst the batteries ‘melt down’ and consume themselves.
 
Once one cell is violated in a battery powered car, and starts cooking, the end results are thermal runaway, pretty much cant be put out.
One method is to blast the cells next to the violated battery with water to help keep them from hitting ignition temp. Tesla started encasing their batteries in titanium so keep them from being exposed or opening up during a collision. Helped...a little. Cost a lot!

Bottom line for fighting a lithium ion car battery afire?

Let it burn.

And the gasses that said fire gives off are some of the most toxic and dangerous out there. You don't have to breathe them for them to kill you.
Hybrids are really hideous as you have a tank of gasoline next to a 1500 degree heat source that cannot be extinguished.
Hint: don't let it happen in your garage.

This is a good piece on battery powered cars that catch fire.

Electric vehicle fires: Where the waiting game wins

Firefighters love testing new tactics and tools, but some methods simply don’t address the key issue with EV fires

Lithium, like sodium reacts violently with water ..... water is actually feeding the reaction.
As others have said ..... better to let it burn ..... use the water to save combustibles nearby.
