Use aluminum wiring in a house they said, no problems at all they said.

Aluminum wiring in a house can pose significant safety risks. Homes with aluminum wiring are 55 times more likely to have fire hazards, particularly if built or renovated between 1965 and 1972. Aluminum wiring can lead to arcing, which increases the risk of house fires.

Well, it all sounds good, but then, I've learned that when something sounds that good, it usually isn't.

Questions include how the tests were influenced by how the battery was charged, how they measured the degradation, and what the battery does after 10,000 charges.

Saying the battery only loses 1% after 10,000 charges suggests that it would only lose 2% after 20,000 charges, but the reality is that the capacity may fall apart and drop to only 20% capacity on the 10,001st charge.

I'll wait until these batteries have been so documented and approved that they begin showing up with commercial availability.

We'll find out then just what is the catch to these batteries.

Is Aluminum Wiring in a House Safe? | Angi

you think thats bad you should see how bad the boats made out of aluminum are,,

I heard they sink the minute you put them in the water,,

They are fine, they don't have current running through them.....Though they might run with or against the current.

are you saying aluminum used in one way doesnt have the same problem as another??

it would help if you explained the real problem with aluminum wiring instead of just making up bullshit comments,,

 

[HikerGuy83]

I am totally a fossil fuels guy, but all technologies go through evolutions.

That is one the problems with early technology adoption. In six months, there might be a better mouse trap on the market. So, you have to decide "should I buy or should I wait?"

Let's hope this kind of things goes forward. I really don't care about greenhouse gasses, but if the technology can cut the cost of transportation, then

GREAT !

Is Aluminum Wiring in a House Safe? | Angi

Yup, it's no longer used in domestic dwellings. My son is an electrician and he saves the scrap. The only aluminium he brings back is industrial sized cable, 2" to 3" diameter. It contains 3 triangle cores. As for any kind of battery, in the future houses will be plugged into a fusion reactor.

pretty much every house in the USA with 100amp or bigger has aluminum coming into the house,,

What are you fake repping for you retard. Yes, as I said, it's no longer used in domestic dwellings. The above are two texts with my son. The first one last Friday about amperage into domestic houses. The second is if Aluminium wiring is still used in domestic dwellings. The answer is no for the reasons he's mentioned, yet it's not banned. Like I said, it's used commercially, so the likes of electric companies still use it, but not electricians doing work in domestic housing. If you still use it in the US, good for you, but not in the UK. It tests crap and it's a fire hazard.

You need to read better.

That is no longer prevailing practice and with the many weaknesses of Aluminum wiring now know to be a major cause of house fires, here is an article written by a certified Home Inspector showing that Aluminum wiring in the home is bad idea.

Aluminum Wiring in Houses: Safety Issues & 3 Repair Options​

Hubert Miles | Licensed Home Inspector, CMI, CPI

Updated on June 14, 2024

Excerpt:

You’ve heard negative stories about aluminum wiring, which might be true. Since I can’t read your thoughts, this post will debunk myths and provide answers.

The bad news is that solid aluminum wire is not good for branch circuits. Many houses still use aluminum wire for stoves and main power.

Solid aluminum wiring has many downsides, including rust and creeping. Aluminum wires are unsafe and can cause arcing, leading to house fires. Although aluminum wiring can be risky, there are ways to reduce these risks and use it in your home.

First, forget the controversy; aluminum has a rich electrical wiring story. Of course, it is not as decorated as copper, but it is worth mentioning.

Is Aluminum Wiring Safe? Common Problems and Safety Issues​

Many homeowners and homebuyers wonder if aluminum wiring is safe. Unfortunately, no, unless you’re speaking of multi-stranded wire.

Aluminum has several issues that make it a less attractive wiring option. Many homes started using aluminum and discovered these issues. These are three of the common problems that affect aluminum wiring:

are you saying aluminum used in one way doesnt have the same problem as another?

It would be hard to say that an aluminum boat is prone to arcing and sparking until they’ve been attacked by a swarm of electric eels.

Boats in the water, regardless of their material, aren’t likely to be used for passing large electric current.

you may want to read that again very closely,,

Typical sizes of wires for 100 Amp Service are 4 AWG or 2 AWG for copper wiring and 2 AWG, 1 AWG, or 1/0 AWG for aluminum or copper-clad wiring. These sizes are also used for direct burial. When choosing 100 amp service wire size, remember that a 100 amp circuit at 240V can proceed up to 24,000W of electricity.Mar 23, 2023

youre taking it out of context,,

his claim was aluminum shouldnt be trusted because in another application it has problems,,

Well, it all sounds good, but then, I've learned that when something sounds that good, it usually isn't.

Questions include how the tests were influenced by how the battery was charged, how they measured the degradation, and what the battery does after 10,000 charges.

Saying the battery only loses 1% after 10,000 charges suggests that it would only lose 2% after 20,000 charges, but the reality is that the capacity may fall apart and drop to only 20% capacity on the 10,001st charge.

I'll wait until these batteries have been so documented and approved that they begin showing up with commercial availability.

We'll find out then just what is the catch to these batteries.

OK, so they only have a range of 500 miles, far less than claimed. So 10,000 charges represents 500 X 10,000 =5,000,000 miles. I really don't think the 5,000,001 is a problem. If the battery lives up to the early estimates it will certainly be fast tracked, so we should see soon if it lives up to the early brags.

You might be right, but I'm trained to assume the worst, so, I have to figure that most people will keep their cars charged by recharging long before the "tank is empty" because they never know when they will have another chance or pass another convenient working charging station.

Only California has a fair number of Tesla EV charging stations, many are always famously not working, so what are the odds of finding an aluminum battery charging station? And what about charging at home? How will that be done, what will it cost and how long will that take?

Then there are the brownouts where the city orders you to conserve electricity by not charging your cars.

So that 10,000 charges might only be 5,000 charges and instead of 1000 miles or even 500 miles, they might be every 100 miles, about what most people drive per week. It still looks good on paper, but what will it cost? And the ultimate determinator will be in real world independent testing.

What I really wonder if that if these aluminum batteries are so promising, and aluminum is so cheap and plentiful, why did we waste so much time and money chasing after lithium?

My experience in the R&D field is that it was deliberate, what they call designed obsolescence--- basically, milking the consumer along to maximize the amount of profits made at the user's expense.
