GM is pulling back on EVs

[Burkey]

Radiant cooling at night, and he thought the concrete would reflect sunlight.

He had a theory and was wrong. He also buys into the man made warming crap since it was hammered into his head since kindergarten. He is now using his engineering brain and finding out what he has been taught is not correct.

I knew this was going to be fun.

I can almost guarantee that a lot of what he was taught in school was wrong. When I went to school, there were 5 vowels. Now there’s 6. Was my eduction incorrect? Or, were we being taught what was known at the time? Do you see any correlation?

You’re telling us that your son failed to make the basic observation that concrete can become so hot in summer, that you can’t touch it without burning your skin….

However, he DID make the observation that clean concrete can in fact be quite “reflective”, meaning that the reflected light is within the frequency of what the human eye can see.

I wonder if a scientist might be able to explain why it absorbs heat so readily but reflects visible light?

Did his engineering degree cover the different forms of radiation and which frequencies they operate in? Does he now properly understand the riddle that he couldn’t solve by himself?

I remember a while back when you were telling us what a bunch of dumb shits engineers were. Unable to design basic systems and components so that they wouldn’t fail….obviously there are exceptions though.

Hello; Why not answer the question yourself.

Yep, they are the smartest dumb shits around. He can design a space craft but has trouble with hands on stuff, just like 99% of engineers out in the world.

So .04% vibrates so fast it heats up the other 99.96% so much that the earth will die. It only vibrates while facing the Sun. But .00000whatever of methane holds onto the heat so the vibrating heat won't dissipate into space?

I have some Ocean front property in Arizona I'll sell cheap.

Not only do YOU not have any idea what you’re talking about, but now, I don’t either…… Is your understanding THAT poor that you can’t even articulate your ideas coherently?

 

[K4fxd]

Makes perfect sense to me.

.04% of the atmosphere is Co2. You claim this Co2 vibrates from IR frequencies. The IR is only available while the Earth is pointing at the sun. During the dark period the Co2 stopps vibrating and the heat dissipates into space. Then you brought up methane which is 0.00017%. So I just supposed the .00017% of methane trapped the heat that was generated by the vibrating Co2 atoms, or molecules.

If you believe this I have some "ocean front property" in Az for sale cheap.

Because your retailer thinks you‘re an idiot.
I have no idea how solar on your house would cost more than 25% more for your home than it did on mine WITHOUT converting from USD to AUD, which only makes the equation worse.
7kw’s of panels on my shed, 5kw inverter.
13kw‘s of panels on the house, 10kw inverter.
$18k AUD installed. ($9,200 USD).
On track to pay itself off at the end of year 4.

Your payback period may well be due to how much sunlight you actually receive each year, or how much energy you actually consume, or any number of things.

Put differently, the fact that you can’t make it work, doesn’t mean that it can’t work. It can, maybe just not for you, with your usage and your location, which is when a person might take that money and invest in a solar (or wind) farm in an area where the conditions ARE right. Done well, the returns are pretty good, which is why solar farms are springing up all over the place here in Australia….

Wrong , but we all know you are a paid shill.

The HOA that governs the Decatur condominium in Colorado recently banned electric vehicles from its parking garage, reports the Summit Daily.
According to the outlet, residents received an email that said electric vehicles could no longer park or charge in the facility due to concerns about “increased fire risks if an (electric vehicle) fire happens in our garage.”
The HOA further claimed that “water will not extinguish a battery fire in an (electric vehicle), making a sprinkler system useless,” and that the design of the garage wouldn’t allow firefighters to address the situation effectively

Read this earlier as well. I was surprised this hasnt popped up before and more often. I’ve been around a few of these fires and it is not like dealing with a normal vehicle fire. Pretty crazy. I’m sure you recall the entire auto transport ship that went down due to a battery fire.

Hello; Several times the fire issue of BEV's has been posted. The comeback is ICE vehicles also catch fire, but this is not the main issue. Sure, both types can and do catch fire. The problem is an EV fire is so much more difficult to extinguish.
From what i have read even with many thousands of gallons, sometimes tens of thousands of gallons, the fire hazard is not over. Salvage yards apparently reported burned EV"s reigniting days later in their yards. The chemical energy of a battery is of a different sort of energy than the bonds between atoms of a fuel such as gasoline.

I had briefly heard of a container ship fire during which two firemen lost their lives. If that is the same ship fire caused by BEV's I was not aware.

The initial blaze is said to have started in the cargo hold, where thousands of cars, including some battery-electric vehicles, were being shipped to North America

It doesn't actually say what started the fire but you (and others) have assumed it was a BEV that started it. This subject has been brought up many times on this thread, in fact EV's are considerably LESS likely to catch fire than ICE powered cars.

Maybe a less 'sensational' report is here

Felicity Ace Fire is Out | Why Do Car Carriers Have Such Trouble? (autoweek.com)

The cause of the fire is still unclear. Keep in mind, gasoline cars are far more likely to have fires than electric cars—60 times more likely for straight-up gas cars and 200 times more likely when you combine gasoline cars and hybrids compared to EVs

It could have started in an EV (and even then it may not have been the HV battery) or more likely in an ICE car. Of course once the fire starts in enclosed space like that everything else will burn with it. I suspect we will never know.

Hello; I must figure Gregs still has me on ignore so this will not get thru into his safe space. He again ignores the bigger issue of the intensity of a BEV fire in terms of how difficult they are to extinguish.
If i am no longer ignored, then he pointedly omits the issue again. A fundamental problem without a good solution so far. A partial solution may be using firefighting foam. Foam has its own call a lawyer ad on late night TV now. Suspected of causing cancer.

A few weeks ago, a rechargeable floor vacuum had to be discarded. It would take a full charge, but the motor was bad. I removed the batteries and metal parts so they can be recycled. I had an issue with the individual Li-ion cells. Each was fully charged so would be risky to throw into a bag and carried to an area battery shop.
I rigged up an old 6 volt Die -hard lantern bulb to drain the charge by taping leads to the battery cells. That allowed the energy to dissipate as light energy. Took a while to drain all the cells.

The comeback yet again is that ICE also catch fire. True enough but not the serious issue. How to control the fuel differs greatly. With an ICE the fuel can be transfered with a pump if there is not a fire or washed away and diluted. To dissipate the energy (fuel) of an EV will require a circuit with some sort of resistance to slowly transfer the energy. I used old light bulbs but electric motors or resistance wires could have been used.

A bottom line is an ICE fire can be suppressed with hundreds of gallons of water. EV fires are known to have taken tens of thousands of gallons of water. Not a difference without a serious distinction.

EV fires being more intense is just a fact of life. Batteries carry 100% of the energy used for propulsion, gas cars only carry 50%. So with a gas car fire, all you have to do is cut off the oxygen supply which is relatively easy, and problem solved. With an EV, cooling the affected part of the pack is not as simple since you can't really see where it is. You need that sustained, constant cooling to defuse the runaway cell and stop it from involving other cells in the energy release.

For what it's worth, EV's are less likely to catch on fire in the first place. But it's just the way things go, some technologies will have disadvantages.

Absolutely. The main point I was trying to make was that the cause of the fire on that ship was unknown, ICE cars are more likely to have started it than the EV's from the probabilities but it may not have been the cars at all. However once alight in that environment everything would be toast anyway. There would be little chance of controlling a fire on a ship full of cars whatever propulsion method they use.

Most car fires are caused by electrical faults in the 12v circuits which of course are common to ICE/EV/PHEV/FCEV

If I own a parking garage and I have a choice of having a car on fire I'll choose an ICE all day every day. A BEV fire would destroy the structure. An ICE probably not.

Lots of parking garages are under Hotels ect, I see massive problems in the future.
