They will certainly use some type of lube on any type friction surface. No escaping the need for lubricants.

The reason I am pro-electric has nothing to do with the environment. It is simply cost. I can get 300 miles out of my electric vehcile at a cost of $1.75 whereas 300 miles on a camry would be $10.75 (roughly assuming 30 MPG and gas price of $1.75/gal). That cost of gasoline also goes up at a greater rate than electricity when the price of oil increases.


That might be true now, but supply and demand tells us that as demand for electric energy increases, so will the price.

I think electric cars are reasonable for personal transportation, but I don’t see how it’s feasible for all transportation to move away from fossil fuels.

Wow. We have very different ideas about America, independence and freedom. But that’s ok because in America everyone can have different opinions.

Agreed, and no one is telling you any different.

Assuming this is a knock on tax credits, which is kind of nonsensical on the topic of freedom. You are free to take advantage of the credit, as are all car manufacturers. Do you only dislike tax credits for "green" products, or are you against all tax credits?

Personally I have no interest in an EV. I want to be able to pull into gas station, fill up in 5 min and go about my business for another 400 Miles. I have 4 vehicles at home. I don’t want the hassle of plugging them in at night and plugging them in at work. I know for sure my wife doesn’t want to fool with that when she gets to work. Next time I pull my boat to the coast and back I don’t want to have to stop on way home to recharge after fishing all day. Or when I go to the camp for the weekend where I don’t have electricity try to figure out how to recharge. I don’t want to maintain several batteries per vehicle times 4. Or next hurricane when electricity is out for few days??
Then EV's aren't for you yet! Though I'm willing to bet that you could easily get by replacing one of your four vehicles with one, and save on fuel and maintenance costs for the next decade. But of course, it's your choice!


My point, though, is that you (and most of us) are choosing to rely on other countries for your transportation needs. We exercise our freedom to remain non-free. And we are slowing America's progress toward being the leader in one of the fastest-growing industries in the world in the process.


It's one thing to choose to drive whatever you want, but it's another to do as many in this thread do and actively work against progress in the EV industry. The ONLY effect that will have is to hurt America, because the EV industry is going to charge ahead with or without us. We'd be wise to lead the way.

You forgot the part about "all other factors held equal". So it's not that simple, especially considering the energy market regulation.

Who said anything about all transportation? If we can just get most of our transportation needs away from fossil fuels, it would reduce our reliance on foreign oil and be great for our national security.

"ETA: and people in Europe have opinions "
You missed the point I was making. People in Sweden, France and Britain have the same opinion I do about EV's but their governments DGAF and have announced Gas vehicle bans. Can't / shouldn't happen in US right?

Subsidies for EV's-
Where do they stop? If EV's become the norm does the government give them on a couple hundred million vehicles? If EV's are so great why do sales dry up in states that discontinue them? example- 2stroke motors are bad for environment and not as efficient at 4 stroke motors. Should the government be offering to pay for everyone to upgrade? Where does it stop?

National security
I am guessing that you are talking about depending on OPEC for our oil. US is now biggest oil producer in the world and a net oil exporter. I lived through the oil embargo in the 70's. Yeah it sucked. Waiting in the lines for gas. Trying to "guard" our vehicles at night because people would come siphon the gas. But situation is far different now. Strategic oil reserve, etc. In my opinion US oil / energy revolution happening now is great for the country.

Again just my opinions. But my family risked their lives to travel to the US because of limited choices and lack of respect of their opinions by the French Government.

On the contrary, since 1960 the demand for electricity has gone up roughly 500%, during that time the average price adjusted cost of electricity has actually gone down.

Again, much of the recharging can be done during off peak hours when there is an excess of generation capability, times when power companies are willing to sell the power at a discount, but few residential customers take advantage of. This could change when demand is higher during off peak but would be realized by few residential consumers.

Fluoride-ion batteries would be more convenient and safer than gasoline and diesel.


Actually not. They have very specific needs as far as temperture is concerned and they rely on extremely toxic electrolytes. Also the technology is extremely expensive and isn't on the horizon for successful mass scaling. As for the efficiency, a Tesla drops 40% of its range in cold weather. That's an unavoidable fact of EV's whereas an ICE only loses a small percentage and that mainly applies to the increase in time spent in open-loop as the engine warms up.


quote:

That would be true if it were just a bigger li ion battery, but fluoride ion batteries charge quicker than li-ion. Also the increased capacity essentially lets you charge over night and give you enough charge for the week while also allowing for better fast charge technology for charging stations. Much more convenient than gas/diesel.


It's true of any battery chemistry, simply being able to accept a charge faster didn't negate the current capacity limitations of the average residential home. You simply have no concept the cost and technical aspects of installing a device capable of handling and delivering 30+kW to a battery without burning itself out. So yes, the battery might be able to accept electrons at a much higher rate, copper wires have a limit and it's expensive to run lengths of 8/3 or 6/3 in a house.

I see, battery tech can make essentially a quantum leap and you'd shrug it off as "less of a benefit than you think", even though by far the biggest drawback of EV's is their range. Meanwhile ICE's haven't improved substantially in a century, but we should stick with them!



I've actually stated that the technology would have to make a quantum leap, but you failed to understand that finer point in my discussion. Not only batteries but power generation, residential electrical supplies, and infrastructure would all have to make considerable technological advances to even give EV's a chance to replace the ICE en mass as you envision.

Well coal is cheap but coal's still black
It ain't never turning green
So plug your electric car in
Charge it good and strong
Do your shopping online we'll get you every time
Just keep your dirty lights on

I did the calculations earlier in the thread to show 2 cars in every household driven the average current milage would only increase residential power consumption by ~30% this is well within current offpeak generation/transmission capability. It was cocktail napkin numbers but show me where I am wrong.

To delivery 30kW of power in a residential home you definitely will run into issues. You are off on your wiring suggestion. 30kW is 125 amps @ 240V single phase and you can't begin to run that on 6 gauge copper (safely). Depending on the type of cable you will need at least #2 Cu. The issue will be much lower in non-residential areas where 3ph 480v is more prevalent. A 50 amp (12kW) 240v outlet should be too expensive in most homes, especially if the load center is in the garage. It would require 6/3 cable but that is about $2 a by the foot retail and around .70 in bulk.

The "wrong" comes in where you are making the usual assumptions within an ideal framework. During the summer there are already large metropolitan areas that can barely sustain current demand, 30% would be way beyond capacity and that 30% is a conservative estimate.

No, I said "runs" for a reason. I just did an install of a 36kW tankless water heater for a commercial customer and that was 4x 8/3 on 40A breakers. 8/3 is over $3/foot retail and a spool is still $2+/foot.

First of all, why do both cars have to be charged at the same time?

So many people talking without direct experience.

I plug my car in every night.

It is on a 50 amp breaker pumping 240v at 40 amps.

Yes a 6/3 cable was required.

Not understanding what the issue is? This is less then a home with 2 separate 4 ton HVAC units running on two 60 amp breakers correct?

First, SHOW me how the 30% is conservative and how it is only on an ideal framework and how reality differs. Also, note that 30% is just against residential demand, not the full demand. You seem to be missing that the majority of charging is and will be done at off-peak hours not in the heat of the day, areas with very cold climates don't rely heavily on electricity for heat due to cost.

8/3 is over $3/foot retail and a spool is still $2+/foot.


If you or whomever you work for is paying $2+ per foot for 8/3 NM on 1K spools you/they are getting raped. 8/3 NM is ~1,300 for a 1K spool RETAIL at the cheaper places, you can buy it under $2 by the foot at HD last time I looked.

If you have numbers I am happy to look at them, I won't say mine are perfect but if your numbers are wonky like your cable costs then they won't be of much use.

You should do some research.

My car gets more miles per charge then your car does on a full tank, I'd wager.

Secondly it takes you 10 minutes to run to get some gas. Do you know that the superchargers pump 72amps and 440v? Charges well over 200 miles per hour at that rate. In 10 minutes I can add about 40 miles. You taking a lot of unplanned 40+ mile trips?

Lastly, the car is smart. It KNOWS where the charging stations are and will reduce power as needed to ensure you never get stranded.

Talk about thinking harder, how many times do you get gas a week? Twice? so a minimum of 20 minutes a week to refuel? I'm at zero. Literally zero. You are wasting 18 hours of your life every year sitting at a gas station, while I'm at zero. 18 hours --- per year.... I can almost get to New York City in that time.

And you are talking about an unplanned trip? Do you make 18 hours worth of those every year???

The issue is batteries of different capacity or chemistry. If the battery capacity increases then you'll need a bigger charger (read: more current) to charge it as quickly as a lower capacity battery. If using batteries that can accept charge at a faster rate you still need a bigger charger. HVAC units need bigger breakers to handle the surge when they come on, running current is far lower. A charger maintains a high current draw for as long as the batteries require it. You are charging every night on batteries that are not even close to depleted, how long does it take to reach full charge? Now imagine if you wanted to charge in the same time it takes to fill up an empty tank of gasoline, vastly different requirement.

It's not as if you're standing there the whole time. It takes a couple seconds to plug in. Who cares how long it takes as long as it's charged by morning?

Blinders? I said by far the biggest knock on EV's is the range. A poster suggested a solution for that, and you went off about how long it would take to charge and the wiring requirements, so it's not really all that great. You're trying too hard.

No, not at all like a cheap Bic lighter. Butane is a gas at room temp, if a small container leaks no big deal. We were clearly talking about the safety of gasoline and diesel, so why are you talking about butane?

I know, it's big news when a lithium battery catches fire in someone's pocket. Know why? Because it's so fricking rare. Contrast that to vehicle fires, and only those that start in the fuel tank or fuel lines. That happens on average over 8 times a day. Are you sure you want to continue this argument that liquid fuels are safer than batteries?

There are no "considerable technological advances" required for power generation or infrastructure to handle EV's en masse. If EVERY SINGLE HOME in America switched to EV's overnight, we would probably see a 25-50% increase in RESIDENTIAL energy consumption. And considering most of that increase would be during off-peak hours, our current capacity and infrastructure might be able to handle that right now. Given that it will likely take decades for everyone to switch, I'm more than sure we won't be dealing with brownouts all the time.

Power generation capacity might need to be increased, as well as infrastructure in some places and residential energy supplies will need work or upgrades, but there are no technological advances required. Today's tech is more than capable. Energy storage is the only area where "considerable" technological advances are needed to fill all needs, but plenty of people are getting by even with today's tech.
