Nikola Tesla. He was the man behind some of the greatest inventions of all time, including radio and alternating current. But perhaps his most visually fascinating invention is the Tesla coil. While maintaining a low current, it can produce dangerous high frequencies and voltages that can well exceed 1,000,000 volts, discharging it in the form of electrical arcs very similar to lightning.
The Telegraph reports that a team of researchers lead by Dr. Sang-Woo Kim of the Institute of Nanotechnology at Sungkyunkwan University in Seoul have developed a method for converting the energy from sound into electricity. They've applied the research to the charging of mobile phones, and while you don't have to yell with all the emotion and fear exhibited above by Drew Barrymore in Scream, it sounds like the more energy the better. Dr. Sang-Woo Kim says:
Another example of outstanding resourcefulness and ingenuity in the medical community (see earlier this week: Blood Sucking Plunger Could Heal Millions).
Redstone and electricity have much in common. They both have what's called resistance. That is, they only travel a certain distance before the signal degrades to the point where it's unusable, and they take a certain amount of time to get there. With electricity, that time is nearly instantaneous because electricity is extremely fast. Redstone, on the other hand, is pretty slow.
In this article, I'll show you how to make a portable prank stun-baton. Powered by static electricity, simply charge up the baton, and discharge it for a static surprise. The concept behind this device ties in with Leyden jars, and their tendencies to retain static electricity.

According to the article, there's going to be HDBaseT, which can carry both video and audio signals, and a network connection, a USB connection and electricity with a single cable.
If you ever find yourself in the unfortunate predicament of being stranded outdoors in the snow, don't eat snow off the ground. Eating solid snow will sap your body of precious internal heat (since the heat will be used to melt the consumed ice), so it is best to melt the snow completely before drinking to stay hydrated.
Direct current (DC) by definition flows in one direction. Alternating current (AC), on the other hand, periodically changes direction, or reverses polarity. It is indeed possible for a portion of a circuit that is normally DC to periodically change direction, or reverse polarity like an AC circuit.
This low impact woodland home in Wales is the cream of the crop. The woodland home was built entirely of natural materials, and best of all - only took 4 months and $5000 to complete.

However, the circuit described in this article consists of a flyback transformer, n...
In this series, I'll be exploring electromagnetic weapons, how to build them, their function and application to the future, and the amazing possibilities electromagnetism has to offer. First, the electromagnetic pulse generator, or EMP. You've probably heard of these before, and their devastating effects on electronics. A simple EMP consists of a capacitor, transformer, trigger, and coil of copper wire. This, when triggered, would produce an intense magnetic field for a brief period, similar ...
