Tesla - Master of Lightning: A Weapon to End War. Tesla inherited from his father a deep hatred of war. Throughout his life, he sought a technological way to end warfare. He thought that war could be converted into, "a mere spectacle of machines. " In 1931 Tesla announced to reporters at a press conference that he was on the verge of discovering an entirely new source of energy. Asked to explain the nature of the power, he replied, "The idea first came upon me as a tremendous shock... I can only say at this time that it will come from an entirely new and unsuspected source. " War clouds were again darkening Europe. The idea generated considerable interest and controversy. By 1937 it was clear that war would soon break out in Europe. What set Tesla's proposal apart from the usual run of fantasy "death rays" was a unique vacuum chamber with one end open to the atmosphere.

Of all the countries to receive Tesla's proposal, the greatest interest came from the Soviet Union. GOOG CEO Predicts A Predictable Future Web - Stunning Absence Of Any Real Insights.

GOOG CEO Predicts A Predictable Future Web - Stunning Absence Of Any Real Insights

I'm rarely impressed by Mr Schmidt's predictions or analysis of Internet trends. Even though he is CEO of Google, his position seems to fail to provide him with much insightful to say about the future Internet. Take a look: Google's Eric Schmidt on What the Web Will Look Like in 5 Years Chinese language will dominate the web? So what? Teenagers are the model, they move seamlessly from app to app? There is less of a generational gap than many people without teenagers think.

Five years is a factor of ten in Moore's Law. Distribution distinctions between the web, radio and TV will go away. People will listen more to other people than to traditional sources. LED Lights Make Augmented Vision a Reality. LED Lights Make Augmented Vision a Reality Okay, this is just freaky.

LED Lights Make Augmented Vision a Reality

We know LED lights are versatile enough to be used for practically anything, but LED contact lenses? Really?! Yes, as it turns out, really. University of Washington researchers have figured out how to implant semitransparent red and blue LED lights in contact lenses, for the purpose of receiving and displaying data in sharp visual images and video. Once miniature green LEDs are developed (and they’re in the works, as of now), full color displays will be possible. Lead researcher Babak Parvis comments “You won’t necessarily have to shift your focus to see the image generated by the contact lens,” it would just appear in front of you and your view of the real world will be completely unobstructed when the display is turned off.

Ah, the real world. Thanks to Extreme Tech for the quote and Trendhunter for the images. Practical Advances in Everyday Living. Heat-Releasing Walls To keep a room cool, just let the walls melt.

Practical Advances in Everyday Living

That's the trick with National Gypsum's Thermalcore, wall panels that absorb and release heat to maintain a comfortable ambient temperature without air-conditioning. At the core of each panel are paraffin-wax capsules made by BASF. When the temperature climbs above 73 degrees, the paraffin melts, drawing in heat and slowing the rise -- much as a melting ice cube "absorbs" the heat of warm water to cool it.

With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures.
