Global Warming

It's already being done: it's called co-generation. Unfortunately, a certain amount of heat energy is still necessary to ensure that exhaust can discharged from the stack etc, so there is a limit to how much energy can actually be recovered.

"As Engineers what solutions can we suggest to the world?"

Does anyone know how to design a Political Scrubber?

Getting politics out of the subject would be the biggest single advancement humans could ever make on the subject.

Hey A.H., your forgot to mention tha a "Lawyer Scubber" is needed as well for any advancement to be made by mankind on the issue of Global Warming!!!

it keeps coming back to "hang all the Lawyers....." time after time after time! LOL

You get the Lawyer Scrubber free if you place your order of the Political Scrubber in the next 30 minuets.

We have nothing to do with politians let them do their job we will have to do ours. We are silient workers for wellfare of human kind.

An environmental engineer is the last person to ask your question too, they ony are taught environmentalpolitics with a spot of engineere, just enough of both to be dangerous.

now break out the Thermo books and lets discuss the laws of thermo

"An environmental engineer is the last person to ask your question too, they ony are taught environmentalpolitics with a spot of engineere, just enough of both to be dangerous."

Oh boy, then that means I cut out every single class on environmental politics. Funny, my attendance showed 100%, and all I'm ever interested in is remediating environmental damage, developing alternative energy and pollution control.

Dear Vicini,

Your comments regarding Environmental Engineers is way way off base and totally incorrect. I don't know where you got your information in regards to EE's. Could it possibly be that you found the info in a trash can that's sitting in your Living Room? Or was it found in the Living Room of that radio jerk /political hatchet boy Rush L.? Hmmm you both spew politically motivated venom equally well, so that must mean that you're cut from the same cookie cutter or are, God Forbid or Heaven help us, twins???? *LOL*

I'm going to set you straight by teaching you something useful about Environmental Engineering. First off, I'm an Environmental Engineer and strongly resent your statements. I'm also a Civil and Structural Engineer. All Bach. Science degrees, and a partially completed MS in Environmental Engineering (Thesis Work needs to be finalized). Hardly any of my EE education involved what you state as environmental-politics, nor were any courses that I took whatsoever involved politics. Other than the requisite General Studies/Liberal Arts courses that all college students (including engineers) are mandated to take now days in the USA and Canada, I can assure you that the remainder of my courses involved the physical sciences, calculus, and engineering courses.

Why don't you go back to school and learn something useful that will benefit mankind, and in the meantime drop your soap-box antics! By that I mean you ought to terminate your politically-motivated gobbledy-gook psycho babble rhetoric agenda!!! It serves no purpose here.

Maybe if you were brave enough you would have registered your true name and location, as well as your educational/career credentials & professional accomplishments that you have hopefully acquired since puberty, all posted for all CR4 Forum membership to read and assess prior to your posting of additional trash can babble????

I'm strongly of the opinion that idiots such as yourself belong elsewhere on the WWW, and not at all involved with the CR4 Forum.

The post has a fatally flaw. Even larger than the one behind the global warming scam.

Global warming is not due to excess heat generated by man's energy use. A brief calculation of the energy incident on the earth from the sun, compared to man's total energy use will show that the heat generated by man is incidental.

The global warming alarmists will say that the reason for warming is the generation of carbon dioxide as a natural byproduct of burning hydrocarbons. CO2 is a greenhouse gas; it is transparent to incoming solar radiation in the visible light frequencies, but blocks re-radiation from earth at the lower infrared frequencies associated with earth temperatures.

Thus it acts to accept incoming energy, but block the flow of outgoing energy, contributing to warming. This actually works on Venus, where the CO2 concentration in the atmosphere is almost 100%. But the global warming alarmists/scam artists/scientifically ignorant hacks (take your pick, and they are not necessarily mutually exclusive) linearly scale the effect down to the earth CO2 concentration - a small fraction of a percent) and predict a few degrees increase over decades, a prediction well below the statistical noise floor, and also ignoring all sorts of other effects which can offset the effect of a concentration as low as that on earth.

Here's an analogy. We know that swallowing a whole bottle of aspirin pills will be fatal, almost all the time. From that we can scale down to saying that swallowing a half bottle will be fatal some smaller percentage of the time, or cause certain problems that are serious, but not fatal. We can continue to scale back our predictions for lower doses, but at the point where we are down to one pill, any sort of scaling is still going to predict some negative side effect. When in fact, there are many good results from taking one or two aspirin, when needed. And in fact a low dose of aspirin on a regular basis is prescribed for some people to reduce the chance of blood clots.

On the other hand, regular consumption of aspirin is bad for the kidneys, so people with impaired kidney function have to be pretty near aspirin free. But this prediction would never be made based on a whole bottle being fatal, because it isn't the kidney's being affected by that overdose. It's like saying that a cowboy who lost a shootout in the old West died of lead poisoning.

So the global warming fad/scam is bad science, to say the least, but it isn't as bad as saying people are releasing too much heat into the atmosphere. If that were all the problem was, we could make a major dent in it by firing all members of the House and Senate of the United States of America.

Oh my God, I never wanted this blog turning into hot discussions and blame game.I would again request all, please, instead of making offensive comments to each other kindly put your thoughts to core of the problem and suggest any solution if you have any.

Commission design of a heat tornado to suck GW into space

or a C02 free zone allowing heat to pass

As Engineers what solutions can we suggest to the world?. Actually heat is energy which is generated by spending more energy. It is wasted in heating up earth atmosphere. Can we not recycle this energy and minimise heat emission and saving of the earth?. Well I am not an Environmental Engineer but I have just expressed my thoughts. Finally it will be we engineers who have to search for solution and give it world.

OK, and then define what is going on, not a consensus but truth (we have plenty of facts to support each side) . When I first questioned the political game aspects, I was bought into the fray of GW, Now called climate change.

1.) The first steps to solving a problem is to define the problem itself.

2.) Second Step, The cause.

But since there seems to be plenty of so called facts and stats that support just about every position.

3.) Since #1 and especially #2 is difficult at best, then use more common sense. One should be good stewards of the planet. By controlling what we put into the atmosphere as well as the earth.

4.) The hard part of #3 is getting everybody on board to try to do this in a equal and fair matter, with equal meaning finically fair, as to not impede economic growth of a country. (Which would make the difficulty of #1 and #2 seem like a cake walk.)

After which one can refine the finer points.

Now suresh sharma: you've been on this site for a long enough time to have at least noticed that climate change is a much contested issue here. Next time may be a good idea to put in some ground rules for posting and facilitate the your discussion fairly. You should have at least known it was going to get into a fray. And it still will, because of the steps needed to be taken and the passion involved.

Dear Phoenix, (Sorry I do not know your real name)

1. My purpose of inviting this topic for discussion was to initiate the Brain Storming session in positive way.

2. All of us in little way can conserve the energy and subsequently reduce warming of the earth.

3.We in India, a rather poor country, consisting of villages are trying to convince the villagers to reduce burning of the forest wood for their day to day cooking purpose.We are trying to prome Solar Cookers. May be such small efforts can save Global Warming.

4. What I wanted was many of us still working in industry can reduce energy consumption by carrying out energy audits by qualified Energy Auditors.Also our other friends who are on the shop floor can give a thought to this problem and can contribute in some way.

5.When I last visited U.S I was surprised to see many big cars parked in school compound.On my enquiry I was told they belong to students who buy gas guzzling old cars as they can not afford new cars. I was surprised to learn that there was no public transport available to them. Now if somebody can take up the issue with local authorities then this can also avoid large scale Auto emission.

Well, I am living 1000s miles away so I may not be aware of your real life problems.

I hope this will meet queries you have raised. I welcome healthy discussions.

Wish You and All Merry Christmas and New Year.

Suresh Sharma.

Merry Christmas, Suresh!

"When I last visited U.S I was surprised to see many big cars parked in school compound.On my enquiry I was told they belong to students who buy gas guzzling old cars as they can not afford new cars. I was surprised to learn that there was no public transport available to them."

There is a public transport system for the kids and it is called a school bus! Still, when you get to be the age where you can drive there is great temptation (and peer pressure) to own and drive a car. That urge settles down a little as they grow older, but the US has a culture of independence and driving at whim is one of those things.

Also, the US is a BIG country and driving long distances is not atypical for us. Just this week I drove 280 miles twice to drop off machined parts at a metal refinisher 2+ hours away from me. Public transportation is just not an option in these instances and it would have turned 4 to 5 hour journey into a 7 to 10 hour ordeal, plus the burden of hand carrying a large package.

Lastly, climate change is a subject that may be very valid, but the problem with the subject is that it has been totally infiltrated by politicians and used as a yoke of tyranny against the people. If there is one thing that causes controversy in the US, it is politics.

Personally, I would just assume to send all of our politicians to Antarctica, but international law would prohibit that.

Hi Hero,

Merry Christmas & Happy New Year,

I understand your problem. Of course you can not carry package in "Greyhound" or "Amtrak". Your case is different. I also understand American culture of being independent, but rising oil prices has pinched many of Americans.Well culture will have have to change to suit current economic situation.Here in India owning a car was luxury of rich people, but with salaries going sky wards young people have their own cars. This has resulted in traffic jams, pollution and parking problems.

Gas is under $3.00 per gallon here, so no one is really complaining.

It sounds like India is going through some rapid growth. I have a number of friends (engineers) that I was lucky to have as working guests in the US for some extended stays. I always enjoyed hosting them at my house. One engineer brought his wife to America and they would bring in some amazing foods for me to try at work. I had them over one Christmas and they cooked us dinner. I love the food!!!

Another engineer I taught how to drive a car so she could get back and forth. It was winter and she was terrified of driving, let alone in the snow. I had a brainstorm and decided to take her to an unused parking lot with fresh snow. I showed her how to do figure eights on the lot. At first she was "white knuckles" as she gingerly turned the car. 15 minutes later she was sliding the car around in circles laughing and having the time of her life. She would not stop! In less than 30 minutes she had a good understanding of what it feels like when a car skids and how to correct it. What a blast!

India is on my list of must-see places one of these days. The culture and foods are amazing. I also look forward to getting some amazing photographs some day.

Anyway, welcome to progress!
