you get 600 high amperage volts running through you you are probably going to boil, linemen have to be real careful with the voltages they work around ,where the electricity goes to ground or exits it leaves holes in the body.

Aparently Tesla's newest cars are 800 volts, others run even higher. I think the power line into my house is only 220 volts, and triple phase industrial motors mostly draw 440 to 660 volts IIRC. How do you even charge something like that with solar?.

That kind of voltage is a totally different beast from the low voltage 12 to 48 volts stuff we usually see. Probably beyond what most electricians work with , as well.

Ok, glad I found the GBR forum, as in GasBikeReview.com.

I was scared there for a minute as I need help servicing the 2-stoke engine on my gas-powered bicycle. Thought about an electric bicycle, but that battery manufacturing does so much damage to the environment and besides, I need something loud so pedestrians on the bike path get out of my way.

Leave it to a lefty to argue using an exception to the rule. Do you understand how lithium is mined ? It's 1000 plus times worse . Plus we aren't talking about E-Bikes . We are talking about everything . People like you don't get it do you ? The save the earth BS isn't about anything other then control . 15 minute cities , Social Credit Scoring , Digital money ? Where do you think that's all leading to ? Especially when C02 is actually essential for things to grow . The more we have the more plant life flourishes .

Electric Cars aren't efficient. Quiet ? Yet we are mining a product that ruins the land , destroys wildlife . Is impossible to dispose of . Plus you still need fossil fuels to produce it . You can't even make batteries without coal mines .

Electric companies are in trouble with supplying off the grid now . To believe this is the future is nonsense . Are we going to plus an extension cord in to travel abroad ? Or is the real goal to make travel of any distance impossible for the average person ?

Many battery packs are designed in sections or strings of cells. The strings can be charged in parallel at a lower voltage and then put in series to get the higher voltage required.

"Lefty?" Why are you assuming that, especially considering Elon Musk is himself a Ron DeSantis supporter?

"Exception to the rule?" Please explain how lithium is mined differently for electric bikes than it is for electric cars.

"Do you understand how lithium is mined ?" Do you understand the difference in quantities needed for one time versus constant refilling? There's a big difference mining something once to build the car versus mining something continuously to fuel it over its lifetime:

And then add in recycling of the battery materials versus the pollution from burning gasoline. Read more here.

"Electric Cars aren't efficient." They are more efficient than gasoline-powered cars. Matter of fact, most EVs are so efficient that even when powered with electricity generated exclusively from coal they pollute less. Look up efficiency of gasoline engines - there are indisputable facts that a gasoline engine can't be more than 35% efficient, due to thermal and other losses.

"You can't even make batteries without coal mines . " Sort-of. It is true that refining of some battery materials requires high heat, which today is economically viable only by burning fossil fuels (not necessarily coal), but again, overall the impact on the environment over a vehicle's lifetime is less for EVs than for ICE vehicles. Here's another good article: https://climate.mit.edu/ask-mit/how-much-co2-emitted-manufacturing-batteries

"Electric companies are in trouble with supplying off the grid now . " That's not really true. California, for instance, hasn't had troubles since the illegal Enron-enabled diverting of power, also due to more renewable sources being added to the gird. And since most vehicle charging takes place at night when electricity demand is low, EV charging actually helps increase power plant utilization, which lowers overall cost per kW.

Of course, you actually believe that more CO2 is better and that EVs are part of a giant conspiracy to control all of us. So, you're your own worst enemy in any logical argument.

 

[PDoz]

Imagine living on a shrinking pacific island and reading BS about the world needing more co2 to feed the trees.

Disclaimer - clearly as an Australian this is just propaganda , an attempt to make our economy stronger by mining more lithium / rare earth metals . We're going to be RICH when the conspiracy theorists stamp out child labour and our lithium is the only globally accepted option.....power to the people.....

If batteries are re-usable . Why is it less then 5% are actually recycled ? What's happening that we aren't bothering ? Is it true they can be reused ? Seems odd if the figures of 90 % can be recycled . It's not being done . Especially when they are so costly environmentally to produce in the first place . As well as economically . The ground where it's mined from can't be reused I think a minimum of 50 years . I believe I have read 100 years . Plus it completely destroys all animal life .

Elon is simply capitalizing : I don't think he believes the planet is in danger . It's not . Quit believing what you read online . How is an EV more efficient. And what pollutions are there in the World besides China . WHo refuses to use Filters . As I said I have no issue with EV as an addition . But as a sole source ? Impossible . Gas and Oil brought us into the Modern Era . Wind Solar and EV is a step back .
You need to keep up . Enron was a lie . I suppose you don't believe millions have died from C-19 Vaccines /

The argument is does the planet need saving ? Are we experiencing more Earthquakes and worse more frequent storms due to climate ? Where's the evidence ? In the 1980's in the USA . We had massive snow storms . Record snow falls . And what did they tell us ? That we'd be in an ICE AGE by 2000. Never even came close . Then it changed to massive heat . Now it's climate change . Climate changes everyday .

Would you agree that most people today are deceived ? If you answer no you are deceived Would you agree Earthquakes and Storm size and frequency are increasing ? Do you agree that man today is self righteous lovers of Self ? That Homosexuality is exploding ? DO you agree we are fast approaching a Digital system with a World govt ? Do you agree that AI can already easily monitor the whole of the planet ? Worse then we have ever seen ? Would you agree there's no current strong world leader with answers for peace and security ? Would you agree Covid was the first virus that ever effected the whole planet all at once ? Would you agree that ALIENS / UFO's with real ships who appear to travel in an out of our dimension. Is a true thing ? Would you agree that among all nations . Israel is the most hated ? Even though they are the most environmentally safe nation by current standards . Would you agree that mankind is not only capable of destroying everything . But that we are already in WW3? Would you agree that over 70% of all the Fish , Birds and mammal wildlife has died off since 1976?
All that I just mentioned in the last paragraph are true things . They are also all things that have gotten way more intense in the last 10 years . Most of us just didn't know about it pre Covid .

...C-19 Vaccines ... Homosexuality ...ALIENS / UFO's ... WW3...
All that I just mentioned in the last paragraph are true things .

I think you left out that Apollo 11 was filmed in a movie studio, that the earth is flat, and that the Sandy Hook massacre was actually a hoax designed so the government could confiscate our firearms.

EVs are not just about ecology... they are quieter, cooler, roomier and less maintenence.

Don't think I'll ever go back to ICE for the inconvenience alone.

I have an EV and dont plan on traveling with it outside of my village (Coachella Valley in So Cal) with it in the near future. Range anxiety is not worth it at my age. I have 2 ICE cars that I can use if I need to get over to the coast or go watch Spring Training in Arizona. Too many times the listed charging sites are either out of order or just straight not working-or there is an ICE car parked in the stall. Give me a Shell or a Chevron or hell even a Circle K for petrol...

 

[BigNerd]

Tesla if you need to do.more than local driving... or rent an ICE.

But infrastructure is improving and 18 minute 80% recharges are pretty good.

I hear ya BN, but I bot a Hyundai Kona mainly for the warranty and the 7500 tax credit. Luckily I have a couple of back up ICE cars. The Kona is great for groceries and golf. I disagree with you on the infrastructure part. Unless you have a Tesla, you are taking a huge gamble on a long distance trip. (unless you like driving from EV charging station to station with the AC and radio turned off sweating bullets driving 50 when everyone else is going 80)

As this thread was going for the weeds, I'll reply to this illustration. I sort of know the theory but haven't the vocabulary to discuss electricity . But in practical terms it means needing a south facing roof the size of three mid-century houses . Or a miracle location.

Drive across Texas, pulling a trailer Vs Drive 2 miles to shopping and 10 miles to work. A hammer and a screwdriver are different tools, too.

As someone living in a miracle location, my panels face north

I drive around 200 km / Wk , so presumably recharging an average 70 kwh ev each week would be more than enough? We average 3.5 kw/h per day from each kw of panels in southern Australia , so doesn't that just mean a 3kw system ?

A 3 kw solar array takes up. about the same roof space as a single carport.

Actually a 3 kw array is quite small, only 6 or 8 new panels, as you say it will fit on a carport or even the roof of a camper, but that's based on 110v to 220v . I don't know the difference between DC volts and AC volts either yet, or what's needed to get to 800v.

I look on solar as a good supplement,I would get a turnkey system from "Iron Edison" and play "wattmiser", you can already buy a small solar dedicated freezer for a reasonable amount, if I didnt have too leave the grid I would stay on the "Umbilicus". People slay Me with their "all or nothing" attitude.
Some Folks need to take a deep breath and consider what the biggest single user of electricity is, wait for it, heating water and space heating, solar( non electric except for circulating pumps) is very goo at heating water. Solar like Fusion( solar itself was once used as a misdirection by big oil, reasd the history) is a somewhat doable misdirection, If Dr.Greer is correct new(old) technolgy will make even thorium reactors obselete, deal with it Nuclear is the closest thing we have to so called"green energy".

It's all good as extra . But they want it as only . Look at Germany or Europe in general . Last winter people burned wood to survive . excessive heat isn't as deadly as excessive cold . Especially on older people

I learned as a kid that most people will always follow the crowd and the status quo . Time is running out . And running out really fast . People are in denial because the Sun still shines . Until the day it doesn't
