Everyone driving electric cars----------what a joke.

I was an engineer after retiring from the Air Force. One of our major activities was called a single point failure analysis. We went over our design from top to bottom to make sure no single point failure would cause the whole system to fail. That was before it was put into production.

I'm not sure I believe all of that, but it's food for thought.

 

Is that a crack at the expense of gingers?

 

And yet we have mechanical failures in the production process of some planes. Is what it is. We are on the whole a reactive
society when it comes to problems.

 

Makes a lot of sense.. I tend to think of it in just two categories. Those who believe in science and those who just make up sht and believe in woo woo.

 

Yup. And in general terms, I don’t think we have enough people out side of the intel and military who get the relationship between terrorism, immigration, weather events and pandemics are all influenced by AGW and the need to make the biggest single user of fossil fuels, our military, more electric and renewable.

Until we do, we have a very piecemeal and ineffective way of dealing with problems. At the heart of solving most of our problems, is technology. We can’t sit here and make fun of science and education and expect to be taken seriously about the electric car not being an important solution ingredient

 

Regarding batteries that are too cold to start the car: if they haven't already, they will fix that problem by making batteries that start in the cold, or creating a warming system of some sort. Just like automatic transmissions were invented so that we didn't have to shift gears, etc. It isn't like they are planning to make one model that we'll all have to drive. Automobile technology is not going to reach a peak any time soon.

 

How nice. How would it be if we all moved there?

 

Toyota gets it, they use nickel metal hydrid batteries in hybrids in the north, and lithium batteries in the south.

 

A disaster. I guess i should keep it a secret.

 

Last year or the year before a section of I83 was shut down for hours during a snowstorm. News reports said a couple of electric cars were stuck and the batteries were completely drained. My sister has a well off in law who bragged about having a Tesla. While he would respond with its range with normal driving, he would never respond when I asked him about the range when using heat or AC.

 

It is warmer today in Seattle Washington than it is in Houston Texas.

I have been reading about Bill Gates’ energy initiatives. Which seems to be more of him funding what Gates sees as promising research and/or technology. Recently he has been saying that he does not believe that either the government or the people will solve the energy and pollution problems. That it will come through technological development. A sentiment I agree with.

Ford has come out with an all electric Mustang. GM has an all electric Camaro. Electric is becoming cool.

 

Two things:

1. This extreme weather is, in fact, the result of climate change.

2. I've heard the tale of wind turbines supposedly freezing from the cold and causing the blackouts, but I'm not sure that's true. After all, don't they use massive amounts of wind power to generate energy in countries like Denmark and Norway? Last I heard, it gets really cold quite often in those places.

Here's what happened to the Texas enery grid:

Ha ha
Exactly. You point out the biggest problem people have converting to solar. Most are living already in decades old houses. It’s hard to rationalize moving out of an area you like just to install solar panels. One can do every thing right for efficiency, but if you live in the woods where the average winter temps are in the teens, you will use some fossil fuels. Minimizing the impact is just as important for some as converting* completely is for others.

 

Sounds like it’s warmer in Maine then in Texas.

 

Hmmm ... no, I disagree. As the technology of wind turbines and solar arrays improves and the devices become more efficient at generating and storing energy, the cost will go down significantly. All technology improves over time.

 

Yes sometimes. But consider the millions of parts in a single airliner. In spite of what is likely numerous component failures over the lifetime of that aircraft, the vast majority are retired without being involved in a single disastrous failure.

I absolutely guarantee you that they have studied virtually every possible scenario. Some go undetected, but it is rare. Ultimately after they go through all of that, it comes down to human judgement to determine whether they have looked at everything as much as possible. They also question whether redundancy is adequate or is something additional needed such as more extensive training of pilots and crew. The Max 737 is a classic example. For minimum aircraft resistance and performance, you have to get rid of natural stability. Those aircraft could not take off without that computer. The aircraft would tumble end over end as soon as it left the runway. No human could intervene quickly enough. They have been designing military aircraft that way for decades. The Max 737 failed too often with not enough training for the crew to recognize the problem soon enough.

It is more than sometimes. I is always for aircraft, but sometimes human judgement if flawed.

 

It's odd how many on the right do that, in order to make your views prove or strengthen theirs.

 

I worked on a lot of projects that had double redundancy which was required for safety reasons when human passengers were involved. Failure detection and correction was designed into the system. Designed a lot of sensor circuits to monitor the system. Redundant circuitry in case there is failure in one.

 

Google is your friend. It took less than 10 seconds to find a long list of articles on the subject, but this one explains it pretty well.

Google "cold weather and electric cars" for more.

 

Are you truly unaware of how arrogant and pompous that sounds?

Would it kill you to google up some information on the current state and plans for improvements in solar and wind technology before posting? There are many terabytes of information at your fingertips.

 

I predict that after this tragedy the Ford f 150 will sell even more more trucks in Texas. It’s hard to rationalize going out and buying a big generator for your house, but if your truck comes with one, the wife will now be much more willing to let hubby buy one of these. 7.2 kw of power is more then enough for emergency home use.

Off topic. A long time ago in a galaxy far, far away ... I once lived on a farm in a remote area of Kentucky. Among other things, I learned how to split logs. I found it to be a zen-like task ... very meditative.

 

It’s really hard for the uninformed to believe in something they can’t see. I bet if this were in the age of Tomas Edison, he’d be considered a wild eyed liberal dreamer.
