What happened to the electric cars and why don't they make them anymore?




Searcher


I was a child in the 70s when the electric cars came about and it seems like you don't see them any more?

Does anyone know why, other than they would be 30 years old now?



Answer
Hopefully they will come back and be affordable in the near future as battery technology improves, but here is the run down on why they were only concepts or projects:

1 - Battery packs weigh 1000 pounds
2 - Batteries lose full capacity after only 2-3 years
3 - Even with 1000 pounds, range was either 40 miles at 80 mph, or 80 miles at 40 mph. Neither made anyone happy.
4 - "Filling up the tank" took 8-10 hours (recharging)
5 - Battery replacement cost every few years was hundreds of $$
6 - Car cost was twice that of a gas car
7 - Batteries took up the whole car's cargo space

However I am part of an EV club myself, and between lithium ion technology and ultra capacators, we should see an affordable one in about 10 years or so. Maybe sooner. The Tesla electric uses 6,000 lithium ion computer batteries and is already under a hundred thousand. $95,000.00 I think. $45,000 just for the replacement battery pack though. Give it time and it will come down.

In the meantime, get a diesel and run B100 biodiesel or get a used Hybrid. Hybrids fix all these problems because the battery pack (cost) can be very small, yet you still can go 300 miles without stopping.

Good luck, by asking this question, I can tell you are on the right direction to making a difference.

My 5 year old has become very possessive of his space, toys, etc. and has increasingly been yelling at, pushing, and taunting his 2 yr. old brother. Today, he kicked him in the head. Time-outs, grounding, and sending him to his room just do not work as punishment for this and it keeps going on and seems to be getting worse. I prefer to use corporal punishment only for truly dangerous situations when other options have failed (child running into street, messing with electric outlets, etc.). I could use some advice here. Should I be spanking my older son for this behavior or would it make things worse (with him then thinking that hitting is "ok")? I need a solution from parents who have been through this. It is completely unacceptable for my older son to be treating my younger son this way but I don't want to escalate the situation -but clearly something needs to be done to protect the younger one.


Answer
If you spank your oldest son, he will not think that makes it okay for him to hit. Just because you take away a toy as punishment doesn't make him think he can do the same to his brother. I know, he already hits, pushes his brother around, and already takes toys away from him. If you don't put a stop to it, it could escalate. Children understand the difference between hitting and spanking. If they don't understand completely, they can learn really quick.

People are not allowed to hit, but a spanking is a disciplinary action used to stop/prevent the misbehavior of someone you are responsible for. Children know that responsible adults are allowed to drive cars, but they are not. Children need to learn that they can play catch outside, but can't throw balls at people's heads or inside the house at all.

Children need to learn that responsible adults will do whatever it takes to teach their children to behave and follow instruction, but that doesn't mean children can hit or mistreat people (especially their little brothers who they should treat with kindness and care). As it is, you are the only person who can stand up for your 2-year old. Truthfully, it sounds like your 5-year old needs his whole general attitude worked on.
