High Voltage Happiness? How to Make a Negative Ion Generator « Fear Of Lightning. In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits. However, they also look amazing in the dark (check out the photos below, purple plasma is amazing!). And if all else fails, they make a cool nightlight. If you've ever been around a Tesla coil, cathode ray tube TV or sometimes even on a trampoline, you've probably noticed that smell; the smell of "static" electricity. I say "static" because, in this case, negative ions are produced by "streamers" of electricity looking for their positive counterpart.
The Circuits Parts There are two simple circuits for creating negative ions (there are more, but I'm only covering the easiest and most effective). Circuit 1: Note: The circuit diagram specifies 220 volt AC input. Circuit 2: (extracted from Wireless Transfer of Energy) Using a screwdriver specific to your TV's screws, carefully open up the TV.

If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). Reaction_version5.swf (application/x-shockwave-flash Object)
Amazing 3D Printer Video. 10 Common Misconceptions Dispelled. Can The Human Brain See Quantum Images? The strange rules of the quantum world lead to many weird phenomena. One of these is the puzzling process of quantum imaging, which allows images to form in hitherto unimagined ways. Researchers begin by creating entangled pairs by sending a single laser beam into a non-linear crystal, which converts single photons into entangled pairs of lower frequency photons, a process known as parametric down conversion. A continuous beam generates a series of pairs of entangled photons. Next, they send the entangled photons towards a pair of detectors. Each member of an entangled pair by itself fluctuates in random ways that make its time and position of arrival uncertain.
Use one of the detectors to receive just one half of the entangled photons and the result is a blur, smeared by the process of randomness. But use two detectors to receive both sets of photons and the uncertainties disappear, or at least are dramatically reduced. Of course, there are some significant experimental challenges.
