Why Tesla's are bad at towing!

Tesla said they have a goal of installing solar panels on the roof.

Yeah!!! If can now adds 50ft of range per day.

I'm exaggerating a bit but run the calculations on how much power you can generate given the surface area and angle to the sun available. It's simply not a viable solution to anything.

Batteries are not needed for a dedicated route.

I understand the London tube first ran with steam engines. Doubt that was pleasant.

No they aren’t. I don’t see what they have to do with battery powers vehicles. The only thing they have in common is electric motors.

The problem with your theory of buggy manufacturers and diesel trains is, electric cars have been around for over 100 years. There's been mass produced electric cars on and off for all those years. How come they still aren't the "go to" form of propulsion after 100 years of refinement?

Yes the gasoline vehicle progressed much faster at the beginning. Battery, motor and digital technology have taken a bit longer. The progress has come from other than the automotive industry. Remember when the world thought Elon was crazy to run a vehicle on laptop batteries? It about took the invention of the laptop to make EVs even possible.

The real trouble for petrol is that progress may slow as resources are increasingly directed toward EVs.

As I said it will be interesting how it plays out. Could be a big break in petrol technology soon that puts EVs back in hibernation. Time will tell.

Good point! I wonder if Tesla fanboys also use Unix. The arguments are the same.

Ad hominem fallacy and non sequitor.

I dont remember seeing or being able to buy any good EV in the past,
not until Tesla built it

And everyone driving one will tell you theyll never go back to fosil fuels its just that much better and I have no doubt more EVs are coming

For mass transport Electric is the best most eficient mover,
thats why countries w no natural resources aka oil have been relying on for half a century now with great success

Apples and oranges comparing Electric Cars with Subways or Electric trains. You do see the wires over the trains right? It's great that EV's work for some people. Again they HAVE been around for 100 years and have come and go. Always because of their short comings.

Norway who in March had 58% of new car sales are EV is planning of curb wireless charging.

European countries, unlike us, don't see EV vehicles as political, tree-hugger socialist plot. Just that's economical, practical and environmentally sensible.

I'm sure you all remember nicad batteries. They were a huge step up. But they had some serious flaws, particularly the "memory effect". Unless they were discharged all the way each time--and then fully recharged. Then came nickel metal hydride, a step up--but dendrites remained a problem, solution--charge slowly as you can stand. Now we are at LI. About their only problem is still the dreaded dendrites. As far as I can understand (I may be wrong), that is why they can't be recharged at low temperatures.

The latest LI technology has a "solid" electrolyte. Dendrites may not be an issue any longer.

There are also room temperature sodium batteries with a similar solid state electrolyte.

These last 2 have about 2.5 times the watt-hour capacity of current LI jars.

OK there are roughly 50,000 miles of interstate. I'm sure you'd want to add in all those miles of state thruways and such so lets call the total 70,000 miles. These are all multi-lane so let make a guess and call them 6 lanes, 3 each way, on average. Those will be more expensive to electrify so lets call that $1,000,000 a mile which works out to $70,000,000,000. Who is going to pay for that? I vote electric car owners should foot the bill. Plus the O&M costs.

Not going to happen ever.

But really do you think the first 1% would pay for all infrastructure and then the remaining 99% just come along and enjoy the ride.

You mean like the EV owners are doing right now?
