EOS has proven in the past that 3D printing of structural steel can reduce material consumption by 75% and CO2 emissions by 40%. 3D printing has, according to the firm, the potential to outperform any other traditional method of manufacturing structural steel in terms of sustainability, energy consumption, CO2 emissions, raw material efficiency, recycling, transportation of raw materials and manufactured goods, and many other dimensions.

btw You cannot cast steel. Only iron.

Don't be ridiculous.
Casting Steel

My mistake. I was thinking of an other process when writing that.
It's called the Bessemer process.

That one is more for the SOLUTIONS thread... Will add comment, thanks.

Hopefully, the 3D-printing can pretty much eliminate the waste from machining and from underutilized/unneeded material. As an added bonus, you can get precision parts with aircraft-like strength-to-weight and all for low cost...


Good way to go!

Meanwhile, the natural world continues to respond to our continuing unnatural industrial scale rampant pollution:


Signs of spring 'shifting' in trees

... A 200-year-old record from a Norfolk estate shows warmer springs are causing most woodland plants to leaf earlier. But warmer autumns are having the opposite effect on some species...

... The researchers predict that trees like the oak, which are normally cloaked in leaves relatively late in spring, will soon overtake trees such as the hawthorn and silver birch that traditionally leaf early.

In the long-term, the survival of some woodland plants could be [are likely to be] affected as plants compete for light under the woodland canopy...

Such is the weight and momentum of water and the force of weather that we change at our peril for some areas:


US sea level north of New York City 'jumped by 128mm'

Sea levels along the northeast coast of the US rose by record levels during 2009-2010, a study has found.

Sea levels north of New York City rose by 128mm in two years, according to a report in the journal, Nature Communications. Coastal areas will need to prepare for short term and extreme sea level events, say US scientists.

Climate models suggest extreme sea level rises will become more common this century.

"The extreme sea level rise event during 2009-10 along the northeast coast of North America is unprecedented during the past century,"...

... "There is strong evidence that the likelihood of such events has been increased by climate change, and that we should expect more such events in the future.

"This example illustrates how individual extreme events are influenced by multiple factors - in this case the global rise of sea levels, regional changes in ocean circulation, and wind patterns."...



What new levels of CO2 and oceans do we push with our continued excess industrial pollution?...

http://sealevel.colorado.edu/content/tide-gauge-sea-level

Tide gauges may also move vertically with the region as a result of post-glacial rebound, tectonic uplift or crustal subsidence. This greatly complicates the problem of determining global sea level change from tide gauge data. Differences in global sea level estimates from tide gauge data usually reflect the investigator's approach in considering these vertical crustal movements.

Ah, yes, free hand to be alarmist if you massage the data one way, and nothing at all if you massage the data another.

The article itself if behind a pay wall so there is no way to know if the BBC is just printing alarmist FUD or not. (Alarmist FUD does sell advertising though.)

What to think, what to think .....
http://www.forbes.com/sites/mikecollins/2015/03/07/pseudo-science-and-the-age-of-irrationalism/

Pseudo science ignores the scientific method. It makes conclusions and then looks for facts to support the conclusions. In pseudoscience there is no healthy skepticism about fantastic claims, in fact there is an enthusiasm to accept untested personal testimony as a public truth ( as in the stories about UFOS).

It is more about what someone feels then facts. The elevation of individual testimony or sensation over logic and verifiable fact is not only popular; it is often linked to religion, spirituality, popular psychology and cults. Pseudoscience enthusiasts offer a hypothesis first and ignore facts such as the assertion that ancient aliens were behind most changes in history.
...
Pseudo-science comes in the form of books, products, seminars, newspapers, magazines, pop psychology, religion and TV shows. I think TV is very representative of what people are really interested in because it is based on ratings and numbers of viewers. There are channels called the history and science channels on cable TV but these are oxymoron’s because there is very little real science or history. Most of the programs are about UFOs and Ancient Aliens with a smattering of reality shows like Swamp People.

All of these examples make it very clear that pseudo science is a lot more popular with the public then real science which I believe is a real danger for the future. But before any attempt at making a case for science literacy, it is important to understand why people like pseudoscience.

Pseudo-science is very appealing to people who like black and white or fundamentalist thinking such as creationists and new earthers. People attracted to fundamentalist solutions prefer simple solutions to very complex problems. Secondly a lot of people who took science courses in high school remember very little science because the courses were taught through rote memorization. Third science is not easy to study and many people simply avoid hard subjects. And perhaps the biggest problem is that pseudo-science is easier and more entertaining than the real thing.

And Al Gore ...
http://scienceline.org/2008/12/ask-rettner-sea-level-rise-al-gore-an-inconvenient-truth/

Some of the most memorable images from Al Gore’s movie, An Inconvenient Truth, are the graphics that show how rising ocean levels will dramatically alter our planet’s coastlines. As Greenland’s ice sheets collapse, Gore predicts that our shores will be flooded and sea-bordering cities will sink beneath the water leaving millions of people homeless. His narration tells the audience that, due to global warming, melting ice could release enough water to cause at 20-foot rise in sea level “in the near future.”

http://cnsnews.com/news/article/barbara-hollingsworth/wrong-al-gore-predicted-arctic-summer-ice-could-disappear-2013

A 2007 prediction that summer in the North Pole could be “ice-free by 2013” that was cited by former Vice President Al Gore in his Nobel Peace Prize acceptance speech has proven to be off… by 920,000 square miles.

In his Dec. 10, 2007 “Earth has a fever” speech, Gore referred to a prediction by U.S. climate scientist Wieslaw Maslowski that the Arctic’s summer ice could “completely disappear” by 2013 due to global warming caused by carbon emissions.

Gore said that on Sept. 21, 2007, "scientists reported with unprecedented alarm that the North Polar icecap is, in their words, 'falling off a cliff.' One study estimated that it could be completely gone during summer in less than 22 years. Another new study to be presented by U.S. Navy researchers later this week warns that it could happen in as little as seven years, seven years from now."

Maslowski told members of the American Geophysical Union in 2007 that the Arctic’s summer ice could completely disappear within the decade. “If anything,” he said, “our projection of 2013 for the removal of ice in summer… is already too conservative.”

And that widely repeated 97% of scientists number ....
http://www.forbes.com/sites/mikecollins/2015/03/07/pseudo-science-and-the-age-of-irrationalism/

84% percent of scientists think that humans are warming the planet by burning fossil fuels but only 49% of the public believes it.

Human CO2 emmissions as the sole cause agent might even be true, but you don't "prove it" with "fantastic claims", in fact, that tends to disprove it! and make it pseudo science with as much validity as Japanese whale research.

In real science how many experiments are need to give an answer different than the theory to disprove the theory? One?

I Thinks he right. But it's not much we can do about them.
Volcanoes are massive CO2 emitters.
They have caused a lot of mayhay during the history and sometimes caused mass instinction.
But not reducing our CO2 emissions means that it's going to be even worse.

There is a btw supervolcano under Yellowstone Park.
I Think its bigger than that one in Russia causing a mass instinction.

WASTE TRILLIONs where 'it' Don't Count or Mean Anything.

The wast will be the trickle down through those 'greedy who govern' fingers where after each takes his/her 'share' the final reduced result is MILLIONS being spent on Ponzi Schemes of Moonbeams and Unicorn Farts to power an industrial society.

The taxation of carbon emissions should be dedicated to getting humanity OFF THIS MUDBALL by establishing SELF-SUSTAINING colonies on Luna, Mars, Ceres(wouldn't it be cool if the reflection in the crater turns out to be a greenhouse dome?), Vesta and maybe other inner Dwarf Planets. And eventually worlds around other stars.

Only by the insurance policy of the "fruit flies" spreading to other "apples" do we stand a chance of ultimate survival. The Earth WILL suffer cataclysms whether man made or hurled from deep space by an uncaring Universe. If mankind only exists here, when it is gone we are gone (Stegasaurus Steak anyone?).

This is an animated visualization of the startling decline of Arctic Sea Ice, showing the minimum volume reached every September since 1979, set on a map of New York with a 10km grid to give an idea of scale. It is clear that the trend of Arctic sea ice decline indicates that it'll be ice-free for an increasingly large part of the year, with consequences for the climate.

There is a problem.

Terraforming (literally, "Earth-shaping") of a planet, moon, or other body is the theoretical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to the biosphere of Earth to make it habitable by Earth-like life.

I Think we are terraforming the Earth right now in a bad way.
So how could it be possible do it in a good way on an other planet?
As an experiment we could first start making Sahara habitable...

The long timescales and practicality of terraforming are the subject of debate. Other unanswered questions relate to the ethics, logistics, economics, politics, and methodology of altering the environment of an extraterrestrial world.
