Tesla to Texas: How Do You Like Us Now?

[YALE]

Problem is, I'm usually right. Sometimes insanity can let you see things a little more clearly.

Dude, that is not how insanity works. That's how insanity tells you it works.

Then i would like to ask. How do you account for the greater efficiency of the electric motor? It seems the least efficient electric motor is still more efficient than the most efficient internal combustion. 40% vs 95%. copy paste:

Electric motors convert from 50 to 95% of their input energy to output power, generating mechanical rotation much more efficiently than gasoline engines.

Overall efficiency, of course, varies among electric motors, depending on the size and special characteristics of each motor. Motors under one horsepower typically fall within a 50 to 75% efficiency range, whereas larger gasoline engines normally convert only about 25% of the chemical energy they consume into useful mechanical work. Diesel engines, on the average, are around 40% efficient, while most natural gas engines approximate 37% efficiency.



The next gen of batteries is called Lithium air batteries and they have potential to hold 15x more electricity than a li-ion of comparable size. So youd be able to go thousands of miles on a charge instead of hundreds. In this way they would far outdo gasoline. But I do not know when we will begin to see lithium air batteries

This. If electric motors are so inefficient, why do we attach them to diesel engines where we can and experience massive increases in energy efficiency?

We may have figured out why he encountered "insurmountable" problems with his electric car.

Im not a greenie but the fact does make me question all the people saying

"Well them there coal fire plants will power the cars! So its no different!"

Not really. If you made them use the 95% efficient motors just like they regulate gas engines, you would be getting a 70% increase in efficiency thats 70% less gasoline used and a heck of a lot less dependency on foreign oil.

this smiley is gross

As these become more popular, fuel tax revenue will continue to drop and thus, we are about to get a higher gas tax, more road usage fees and more toll roads.

And those tax hikes will be done by all the Republicans in Austin who will blame it on non existant Democrats when the next election comes around.

Sounds like a win-win for your side.

Because Democrats hate to get new tax money that they can hand out....

Please tell us some more fairy tales

[Lajntx]

I find it funny that so many on here have claimed to be pro small government, and complain about dealerships on top of that, then come out in support of Texas banning auto sales that don't go through a dealer.

Because I posted the story. So therefore it must be attacked - No matter how much sence it makes, how solid the facts are, how little the government, or how pro private sector it is.


Watching Fox News and listening to Glen Beck all day does things to people.

There are many prime examples of it on here.

You didn't answer why he was wrong, you answered why you wanted him to be wrong. You may be an automotive engineer who faced seemingly insurmountable engineering issues in the 80's, but don't you think technology has progressed in the last 26 years? Also, just because you're unable to figure something out doesn't mean someone else can't.

It seems to me that you're simply being pessimistic because you don't like electric cars. Which is fine, you don't have to like them. The fact of the matter is, electric cars are here to stay for the foreseeable future.

I was in a hurry so I did not take the time to answer him. Regenerative braking cost more watts then it saves because you are always carrying the weight of the system. The problems that can't be overcome are buss energy losses, how quickly amps can be sunk into the motor and the effects that temp has on the power that that motor can produce. They are also issues that with throttling the motor without large energy losses that has partially been solved through pwm.

Then i would like to ask. How do you account for the greater efficiency of the electric motor? It seems the least efficient electric motor is still more efficient than the most efficient internal combustion. 40% vs 95%. copy paste:

The issue is not the efficiency of the electric motor because that is immaterial. The issues is what is the efficiency of the engine that produced the power in the first place and how much power is lost getting the power to the charger (about 12 percent national average), how much power is lost with the charger(ever put your hand on the charger? It gets DAMN hot and that is lost power)and how much is lost getting from the battery to the motor moving the car.

Dated pics of said electric car, and specifications?

Did you also build a robot?

The car was a 79 rx-7 that had a 90hp GE dc motor; I filled the car with wheelchair batteries that were donated by interstate. No pictures but I sold the car to a man in Flowermound who still drives it from time to time.

I do have a relative who is a specialist in robotics and nano tech who is helping me build the robot sentry gun that someone posted a vid of a few weeks ago to mount one of my 1919s on and will post a demo of it once it is done.

Remind me, who wanted to spend the Texas budget surplus again and who wanted to return it to the taxpayers?

This actually sounds pretty cool.

You seriously don't know how to spell "sense?". Have you ever considered the reason no one sees the world like you is because you're the dumbass?

Someone else will probably confirm if I am right, but I thought I had read somewhere that robotic guns were illegal. I don't think it was worded as robotic but it was talking about what you are building. Maybe I am wrong but that sounds like prison time.

[Ruffdaddy]

My back ground is automotive engineering and I say that you are beyond brain dead if you believe any of the crap that you just posted.

Lol...suuuure. What company is it that you worked for? What design and development work did you specifically do? What's your education?

You sound like one of those old engineers that never properly did anything, failed at a lot and assumed your inadequacies on everyone else.
