The numbers don't make sense to me.

My 5KW Honda generator with an 11 HP engine gives me about 2.2 KW-Hr per gallon of gasoline. An EV going 65 MPH consumes about 16.7 KW-Hr per hour (25 KW-Hr to go 100 miles).

It seems the EV would need a 16.7 KW generator driven by a 37 HP engine and get less than 10 Mi/gal.

Looked into getting a Tesla and our power company said the TVA grid can’t sustain more than 2 EVa on a street. This is their plan to shut the grid down and take control


lol what BS.

Most OT homes will only use about 15% more electricity a month per EV, depending on usage. Besides, people can get solar panels. The US can build nuclear plants. Only a loser thinks this is an insurmountable challenge.

I don't give a shite how good or bad EVs are for the environment, btw. They're a good fit for a lot of daily commuters and some of them are powerful as hell.

There’s a lot of mining needed to produce batteries. Parts of Alabama are already being bought up towards that end. Plus the electricity will be produced by fossil fuels, more of which will be required. The grid infrastructure will need to be beefed up substantially I would suspect. Then there’s battery disposal issues, increased fire risk possibly using less clean generation resources to meet more extreme peak demand… There’s pluses to EVs, but saving the environment has never been one of them.


Every single electric vehicle, regardless of model, utilizes copper wire as well. Copper isn’t difficult to mine but Afghanistan was out copper mine because companies like the Serrie Nevada club and Save our planet have stocks in over sea mining operations

When I’m reality Alaska has 6 trillion in copper sitting a shovels dig below the secluded tundra. Most think prestige rivers, glaciers, mountains and streams when they picture Alaska, and it has that, but the landmass stretches the same distance as FL to New Mexico. 85% is frozen Tundra inhabited by virtually nothing

Honest question. If you take a road trip and have to stop to charge your car, how long does that take?

Generally, 10-15 minutes.

You don't have to charge from 0-100. Using the GPS in the car, it'll tell you how long you need to charge to get to your next supercharger. So you don't even have to charge from 30-100, or anything like that. You just charge enough with a bit of a buffer to get to the next station. On some of the level 3 chargers now, 10 minutes is max, not long at all, certainly not nearly as long as you see a lot of posters in these weekly threads who always say 1-2 hours.

How much range does that get you?

My car's max range is 260 miles.

But please see the edit above on my last post, I added a lot more info


Main thing, you don't have to charge all the way to 100% with each stop, the car will tell you how much you need to get to the next supercharger.

To add a little more info, charging from 20-80% is what you can quickly do in about 15 minutes.

But if you want to charge to 100%, that last 20% takes a considerably longer time, because it has to slow to a trickle when it's filling up for the safety of the batteries.


That being said, the supercharger stations are located close enough that you pretty much never need to charge to 100% to have enough to get to your next supercharger.

I'm thinking I'd always want to charge a bit over what the car tells me, in case of a traffic jam or something. Of course, that could screw you gas or electric.

In a normal day. I can easily put 300 miles on my car. Obviously I go through cars like water. Buying only used cars with about 50-60k on them. Right now I'm running the last coming year on my Nisson with 215,000 on it.

When someone tells me they have a 275 mile range ...that doesn't get me there and back. To make the point. Use Hollywood to describe why.

And Justice for All. The Judge takes our lawyer on a helicopter ride. He brags about challenging the fuel gauge each time out. Past 1/2 tank ....a little further out. Turns and heads to the airport .....ends up in the water and has to wade ashore because the tank ran out.

So a family day trip must be half range to get there and back.

Meanwhile, Wind and Solar equals the garbage burner, like Bayer, The trash burner like the landfill ....they are the grid heavily regulated by the Utility. They can be cut off and the switches opened if the power is unstable or what we call dirty. With careful planning, the Utility must run their transmission lines as if those co-gens are not available.

Where they get in trouble quickly, becomes Texas in an unanticipated, unplanned winter freeze lasting weeks instead of days. Becomes an East Coast black out simply because a tree limb fell across distribution lines that swung the system wildly and took the whole east coast offline .....Why? Because the Protection Relays were not set properly.

And Biden is proud that less than a tenth of a multi trillion dollar fraud will go toward infrastructure.

I am curious to see what the long term effects on battery life will be with all these hot fast charges. Everything I have ever been taught when it comes to batteries goes against fast charging.

range anxiety is definitely real, and I used to do this at first. Maybe under specific conditions I'd still do it but you get used to it and just trust the car at some point.

I love my LED lights and no government mandate had to get me to buy them. They just provide a lot of light that is very energy efficient because they produce very little heat and almost all light.

Then too, there is that bathroom incandescent ligh
t that always went out when I got up to pee.


Agreed. Anyone thinking LED lights are bad are delusional. I still have some in my house that get turned on every day and have been in use for almost 10 years.

Also, when you see a rating for the light fixtures, it's for incandescent. You can put an LED bulb in (say an overhead fixture in your bathroom) that is 10x the incandescent rating.

I don't think a Tesla or EV may be the best idea for anyone who drives that much daily, unless you're getting one of those $100k expensive ones with 400+ miles then I think it makes a lot of sense for the cost savings. But if it's cutting it close on your daily miles, it just doesn't seem worth it yet.

Units that have been 100% supercharged only saw minimal degradation over typical use units.

EV’s are not the answer and I’m a huge supporter. Everything in moderation is good. EV’s are not THE future. They are part of it but ICE will be dethroned simply because of politics. Lithium production is so harmful to the environment.


I am very similar on this. I am not anti EV but they have their limits and roles. They are working feverishly to get the inconveniences like charge times down. But the big epiphany to me was when the Sweedish guy blew up his 12 yr old Tesla rather than change the batteries for $20K. It made .e realize the used car market for EVs is very different than ICEs because once the batteries go the car is worthless and useless.
