Well How do one renew metals? once formed they stay that way - unless they undergo some special chemical/ metallurgical process.

Electricity is produced from steam - coal - or nuclear fired steam. Assuming there are lossess in steam to electricity conversion - using electricity to produce steam may not be possible. The used up steam - in steam turbines/boilers or other process industries are however used in co-generation.

Electric grid concept for surface travel already exist in the form of trams- electric trains

Most of us are like a frog living in a well. The frog thinks, the well itself is the universe as it has not seen anything beyond the well - similarly - our response being what we have seen, what we have experienced - what we believe - what we know. We do not manufacture any knowledge - We only discover or gain knowledge through research and use the same based on our understanding.

Some times I think, we could have been happier without all these knowledge. Were not we people , happy centuries ago - without present day technologies?

You wrote, "Were not we people , happy centuries ago - without present day technologies?"

Technology cuts both ways. However, if just the medical advances alone we have seen in the last century were not available today we would all be living a shorter and more painful lives.

In the end no one else or thing is responsible for your happiness!

That statement is so important I will say it again: No one else or thing is responsible for your happiness!

Each of us must cultivate our happiness and joy from within. It is all about your state of mind.

Thanks.. Hapiness and contentment has nothing to do with technolgoy - it is a mental aspect.

Tehchnology improvement in medicine improved health .. But also raised the costs of medicine and medical treatment and made us to go for medical insurances. it has made us struggle to earn and keep up our life standards and perhaps made us slave of technological advances.

Governments use technology to exert their superiorities over other countries and to control. They sell arms to make money and improve the arms technology further and resell newer arms to make money.

As you said, benefits of technolgoies cuts either way - But technology has made human beings as slave of technology rather than technology as slave of human beings

All one needs to do is look at the average life span of humans over the last 200 years and it is clear we are living longer and in better health.

This has not happened in a vacuum, but is a direct result of advances in medicine irrespective to cost.

No argument that governments use technologies to control people. That is their function.

If people have been enslaved by technology it is by their own choice. People can just as easily choose to free themselves from technology. It is all a state of mind.

I have lots of technology surrounding me, but it does not run my life, but serves my needs as I choose.

Well - good you appear to be at the prime of your life , that is a stage in human life when everything in life appears to be surmountable. I was also like that at one time, and slowly the present advanced medical science has not come to my rescue and I can see that I am slowing down. My views on life or technology now, are much different from what it was 10 - 15 years back. [I am actually a technical specialist in my chosen area]

the human life span has increased due to advnaces in medical science, so is the human population and the necessity that older people need no longer have to retire and need to continue working to keep their extended life functioning at current life styles. otherwise these older people are becoming a social burden. Younger people have to compete with older and experienced persons [like say myself].

It is not easy to live in a society and live differently from others. This is said easier than done. [At least for the majority it is so].

We do not know the art of how we can live without current technology as we have spent most of our life using the current technology. For example , let us say, like our ancestor who used hunting to live. In this sense, we are slave to the technology and the associated life style and this is not an option for most of us.

All human development is need based.

Human beings are blessed with intellects to over come the set backs of things around them and improve their quality of life.

As you say, there is no evidence that human beings were happier centuries back and they are unhappy today.

I do agree upon the fact that we are more greedy, materialistic and feel discontented upon our present status of beingness, a sort of insecurity for the future.Well that is all about one's attitude about life and conceptions about the very purpose of life.

One greatness about all objects[abiotic or biotic for that matter] every thing holds the utility factor right from trees for that matter.

As humans what best we can do is to keep improving our standard of living, share & practice human values in all possible deeds and look out for sustainability in all aspects.

Life on the planet is the gift of nature and Technology development is the gift of human efforts.We can never dispense with it.

At least the engineers' morale should be in high spirits.

thanks.

The discussion has become rather different from the original post. Initially every one tries to do the good by inventing. It may or may not happen that way. As individuals we cannot control anything and most likely we are part of a stream and nothing more.
