If I mention a “green metal” you might think of copper due to its propensity to turn green as it oxidizes. But as it turns out, silver is a “green metal” as well – green as in environmentally friendly. In fact, silver is playing an increasingly large role in efforts to protect the environment.
As you probably know, silver is an important component in the solar energy industry. Now scientists have discovered that silver works better than copper as a catalyst to transform greenhouse gas. This story was highlighted among other technological innovations using silver in the latest edition of the Silver Institute’s Silver News.
Thanks to gold, you may see even sharper images on your smartphone, computer and television screens the future.
We’ve seen tremendous advances in high-resolution technology over the last decade or so. Modern smartphone displays pack millions of pixels in a few inches of space giving us crystal clear images. But researchers at Cambridge University have created even smaller pixels using gold nanoparticles.
This is another in a long list of technological innovations using gold that researchers have developed over the last several years.
Not too long ago, CNBC commentator Jim Leventhal said he had no interest in gold because it has “no uses as a metal.” Of course, this comment is utterly absurd. It goes to show that just because you have an MBA doesn’t mean you have common sense. After all, anybody with an ounce of common sense knows that there are hundreds of uses for gold. In fact, the demand for gold in industry and technology is growing steadily.
Here’s just one example – scientists have discovered a way to use gold to keep your glasses from fogging up.
Overall, gold used in technological applications grew 1% to 85.3 tons in the third quarter. That marked the eighth consecutive quarter of year-on-year growth. Strong demand in the electronics sector helped drive overall industrial and tech demand for the yellow metal higher.
Could gold help us find space aliens?
It just might!
NASA’s James Webb Space Telescope (JWST) is scheduled to launch into space in 2021. NASA claims the $10 billion telescope will allow scientists to “look back in time to see the very first galaxies that formed in the early Universe.” And thanks to its golden mirror and incredibly sensitive camera system, it may allow us to detect alien life out in space.
3D printing is a rapidly evolving technology that could potentially change the world like the internet did. People are most familiar with 3-D printing due to the controversy surrounding 3D printed firearms. But the technology can be used to produce everything from tiny precision components to houses.
Now gold has a role to play in the evolution of 3D printing technology. Scientists at Vanderbilt University have developed a process using gold nanoparticles to reveal tiny defects in 3D printed parts.
