Exactly. My point was the 2 hot lines coming in to the house where not 220 individually. They are 110.
The transformer steps the line voltage down to 220v, two 110/120v phases plus neutral, no ground.
I wish I could afford a Tesla. The Volt is such a joke that I can't even get to work on one charge - I think that the pure electric range is only 25 miles
“Any American complaining about rising food costs has ample opportunity to save a LOT of money by shopping more intelligently and doing more of his own food preparation.”
Very true!
One can even buy free-range chicken and grass-fed/finished beef, if so inclined, and save money compared to eating out.
Explain to me how a nuclear plant has no footprint?...spent fuel rods emitting radiation if not kept cool is less dangerous than an element we get from our amazing planet and we then burn it in some manner to propel or heat and cool ourselves?...The batteries are made and shipped around the world until finally installed into one of the (worthless to me) so called “green” vehicles....Do a little research into the composition of the matal’s needed for the batteries and the trip from mining to final finished product and tell me how efficient they are!,.....THEN tell me what they will do with them when they no longer take a charge?...Another whole toxic pool of coal tar (which used to be used for roofing and it was great as a bitumen...these morons who a scamming billions in this “green” energy scam are so smart that they are stupid,can’t see the forest through the trees!...Oh ya I heard we reached peak Oil yesterday at 3:16 PM EST...
I've noticed the same thing. Several acquaintances replaced their Prius or Insight with VW or BMW turbo-diesels.
Although I agree with you and others that the writer is incorrect (about the 440), you are just as incorrect about the transformer stepping the voltage down to 220. (note: this only applies to transformers used for normal applications like homes. There are manufacturing plants that have their own transformers which have higher outputs because their equipment requires it.)
where I can choose to install 2 pole breakers for 220 circuits or single pole breakers for 120 circuits.
See, even you admit there are 2 120 circuits that have to be combined to make 240.
Another TECHNICAL point. Everyone calls it 110 and 220, but it is really 120 and 240. Simple math would tell you that 120 + 120 doesn't equal 220. Two legs of 120 volts is the max voltage the transformer is supposed to supply. The electrical devices we use are designed to operate optimally at 110 and 220. That's because many times there is a bit of voltage loss in house wiring, so the transformer is designed to put out a bit higher voltage than the devices normally use.
In my huge hometown of Houston Texas I only have seen charging stations for electric cars in the parking lots of Whole Foods grocery stores. I am sure there are more but I don’t know where. I’m not looking either.
When shopping for a new car, I look at a Prius. After contemplating, I told the salesman that it was about $5,000 to much money for the worth of the car. He agreed and said it is the dealer consensus that it is a niche car for people who hate oil companies and would rather give the money (saved in gas) to the dealer and the car maker. I bought an Impala and spent the money I saved on gas.
How about those batteries? How long do they last and what is a replacement cost? Anyone know?
to much money= too much money
The statement was correct. Nuclear power plants have no carbon emissions, therefore no “footprint”. As with hydroelectric power, nothing is burned to create heat.
If you read the article, it did say that hybrid cars are much better than all electric. I have a Ford C Max, and I love it. None dare call me liberal.
I’ve never seen so much HATE in an article.
Electricity from natural gas is a lot cleaner than coal. The article has merit, but fairly broad assertions.
Isn’t this an apples and oranges comparison? What’s the efficiency of an oil refinery used to produce automotive grade gasoline? Not saying they’re wrong on the larger point, but it seems supremely silly to pretend that no energy is lost between the well and the gas pump.
““Then the 220-volt electricity travels along power lines to a transformer which converts the power to 110 volts before going to your meter and finally going from your meter to your home charging station.”
Bull $hit!”
Yes it is. Local power distribution is most commonly done at 12,000 volts and transformed to 220 3-Wire to the home. But the massive transmission lines from hydroelectric installations ( can you say Hoover Dam) are done at more than 70,000 volts. If you tried to distribute at 220 volts, in a couple of miles nothing would come out the downstream end of the wire! If you did that all you would be doing is heating up copper wire.
” I use the free Tesla pumps so I spend no money for fuel. “
Hold on there, my friend. I wouldn’t say its “free”.
I am glad you are happy with your car. You should thank everybody on the board for their generous subsidies to Tesla that were required for you to be able to enjoy it.
You’re welcome.
Please keep it for 500k miles and don’t buy another one, I’m not sure the rest of us can afford for you to.
“We all have 220 in our homes, NOT 110.”
I agree, there are some mistakes here and that makes our side look weak and uninformed. EVERY HOUSE that contains a family capable of affording an electric car has 220 Volts running to it, and that is usually the charging voltage.
The claim that stuck out with me was that 2/3’s of the powerplant electricity produced is lost in transmission. I find that hard to believe. Maybe 10 to 15% or so, but not 2/3’s.
But even so, I still think that a LOT MORE work needs to be done before I’m convinced that there’s any ‘benefit’ to having electric cars on the road or even that they’re any cheaper to run.
For example, one concept that gets talked about, but has NEVER made it on to our highways is replaceable battery packs. Instead of sitting there at a Tesla charging station for hours, how about just swapping out battery packs? There is ONE BIG PROBLEM with that capability - if you do it, then you have to charge for depreciation of the battery pack (otherwise smart owners would just wait until their battery packs are nearly run-out and essentially get a free replacement). Once you charge for that, in addition to the electricity, guess what - more expensive than gasoline - which is why you don’t see it. Now that depreciation is simply hidden in the vehicle, as it ages.
And I also agree with the author that oil companies have NOTHING TO WORRY ABOUT...what can be the threat from cars that are about to hold the equivalent of 2 to 5 gallons of gasoline and take hours to refill (the low number is for hot and cold days when climate control eats badly into battery life)? Then there’s the very limited Lithium supply, not to mention that two thirds of Teslas need drive train replacement prior to 60,000. You may not have to change the oil 5 times, but having to change the equivalent of the engine and transmission on a regular basis is not, what I would consider, an improvement.
