How Green is Green Industry Highlighting "Green Automotive"

01/24/2011 3:42 AM

I have had quite an education of late in the intricate manufacture of batteries for future electric cars.

I have pondered for a few years, whether the pollution from future electricity generation demands will be less or more than the current carbon emissions from gasolene engines. As we switch over more and more to electric cars this becomes a burning question. Without undertaking an in depth study and devoting time and resources that I do not have, I sneakily shelve that deeper thinking.

I imagine many of us do the same when we try to comprehend the long term impact of what we are doing now, on our future health and welfare, we leave the answering to someone else.

I will try to draw a mental picture of the power-pack for a fully electric car, little imagination is at work here and less is needed to see a question.

A power source will be assembled from batteries, very slightly taller and slightly fatter than our current AA size battery. Trays of batteries with approximately 650 individual cells are manufactured. There are approximately 11 trays used in one car. That is a whopping amount of batteries in one car. It is about 7,000 batteries to get rid of when the car is no longer viable or heaven forbid, the battery packs die before the car is obsolete.

Couple this picture with the previous sneaking suspicion, (shelved by Joe Rat in this rat race), that electricity generation will equal or surpass the pollution from current gasolene engines, and it scares me to think of where to dispose of these byproducts.

I am hoping that a few of our forum genii can put this into perspective both from an energy generation to recharge the said batteries and the fate of the batteries themselves.

How about submitting this to the Guinness Book of Records in the pompousness × vacuousness category?

You have spent 6 hours on line, trolling for subjects to dish out snide comments too. Get a life or stay on line and complete your application to Guinness.

Better still have a few pints, it will take the edge off and "Guiness is Good for You!"

Admittedly I do sometimes comment snidely on various posts, but it is not because I am trolling for them--it is because such posts pop up incessantly. Over-unity, electrical questions that fail to provide the voltage, questions that repeat something that has already been treated many times, weird conspiracy-theory noise, obvious homework, no prior effort at research, etc.

FWIW, I like Guinness, among other good choices.

Let me say that the tone of the first two replies would put sincere people off joining the discussion and for that I apologize.

I do hope some people have some different perspective on the issue and are willing to ignore the bad start and share their ideas.

Was there some kind of question to be answered here? Or was it "sneakily shelved" into some deeper thought? Sorry, I don't get it.

Questions: lines 2-3 from start and line 5 from the end!

Innovations never call for external support. It is better you work out your idea in a realistic perspective, say a small scale proto model and know your self. *Battery cars are good for short range transport and not workable for long range transport as well the load and speed capacities.. * If you want to contain single passenger or minimal passenger low range vehicles, focus your work to that limit. *Battery storage of electricity is a fantasy right from Edison's days. The winner is undoubtedly IC engine run by hydro carbon compacted fuel chargers. * Electricity and cars are linkable for zero emissions. but not by batteries.

I can't find a "?" in the original post.

Engineers are trained to make decisions based on hard data, math, and science, not emotions like suspicion, fear, and paranoia.

Battery technology is beyond the simplistic 7000 cell example suggested. There is also a large and expanding recycling infrastructure for battery types typically used in EV's.

With a little research, data can be found that supports the hypothesis that EV's are cleaner(by at least a small margin) than internal combustion vehicles (ICV's) when charged from "dirty" grid sources. If EV's are recharged from home or utility based "renewable" sources, they easily win the cleaner/dirtier debate.

To be successful on a large scale (not the tiny numbers we'll see this decade) any battery system adopted for use in EV's will have to pass environmental impact (both production and recycling), performance, reliability, and cost goals which should guarantee EV's will continue to be a cleaner alternative to ICV's. The reduced functionality(limited range) of current EV's and the cost penalties(even with subsidies) are the major hurdles for now. Battery technology still needs further improvement and sales volumes need to increase to bring manufacturing costs down before we see a mass market movement towards EV's.

While EV's may fill a large percentage of commuter vehicle applications in 20-30 years, I still see many transportation applications where ICV's will remain the only viable option. Fuel "sources" may shift, but ICV's will be around for a long time.

I can assure you that the technology you say is simplistic is very very state of the art in the company that I speak of, it is not a sample , it is a fact.

Their car has gone 300+ miles on one charge. Their battery packs are exactly as I describe to you. Their next vehicle is a beautifully styled 4 door sedan. The battery technology is identical to their older Roadster model. The battery packs may have to be increased to supply power to a much bigger, heavier car.

"Battery technology is beyond the simplistic 7000 cell example suggested. There is also a large and expanding recycling infrastructure for battery types typically used in EV's".

I don't know anything of the recycling of these batteries and would welcome an education on it.

I agree that battery technology will have to and has made great strides in recent years. My Forum thread was just to see what others think on the subject.
