So how does a Tesla Coil that can discharge 1 million volts look like, and what damage can it do? Well, from the next video it seems obvious that you wanna stay WAAAAAYYYYY back when it's operating. Now that is a true light show! Enjoy!

A really cool gadget, which I can see beeing used for an every day commute in the city. Practical, and (maybe) cheap, it would be ideal. Not to mention the lack of pollution, as it would be an electric vehicle! Cool!

Wow. This is something new, and somewhat cool: making your Christmas tree light up from the electricity of an electric eel. Now that's power saving!

Fero-magnetic fluid is the stuff that Ferrari makes its car suspensions from. It's a fluid containing iron particles. When an electromagnetic force is applied to it, it tends to shape itself to the wave lines of the electromagnetic field. You can try something similar at home with some iron shavings on a plate, and a magnet underneath the plate. It's used in car suspensions because it can modify the stiffness of the ride almost instantly. Her's another use for fero-magnetic fluid, this time with beauty in mind, and less practical. Enjoy it!

Here's a cool electric gyroscope, that you could probably build at home. It's very simple, and yet it works amazingly well. Have a look!

Here's a funny video (probably a commercial) where a guy gets pwned by his lawnmower. Very funny! Enjoy!

After seeing how a desk's drawer can sound like chewbacca, it's time to see if a more complex equipment like an electric quitar can match that performance. You be the judge! EnjoY

That's among the funniest movies I've seen all year. The poor goat doesn't know what it's getting into. Look at it getting chased all over the field, until it manages to jump over the electric fence! Haha! Enjoy!

Yeah, well this guy has some pretty good pen spinning tricks up his sleeve, but when it comes to smarts....well that's a whole different chapter. He almost gets himself killed. Idiot!

The best way to find out if your friend is a wuss! Hilarious!

Bored with its everyday activities, a little goat amuses itself in licking an electric fence. Go goat go

If you've been drinking, like the guy in the video, you'd probably might consider taking a second look on the sign on the fence you're urinating on, making sure you won't have any surprises. Wow. That's a shocker!

This tree made the mistake of toughing those high voltage wires. This lead to an electric arc to be formed between the tree and the wires. This arc, eventually vaporized the tree sap and burned the tree in half. Pretty spectacular show! Enjoy!

This baby should go head to head in a drag race with a F1 car, not a Corvette. Damn..this the fastest accelerating, road legal car I've ever seen. Too bad the owner is so full of himself Enjoy the show!

The latest technology for the blind is tongue vision. It allows images to be displayed from a video camera sensor as electrical impulses to the tongue. It seems that the brain can adapt, and with time it can be used naturally. The only drawback is for the moment it's low resolution. Hope they fix it! Enjoy!

For the first time a gene was identified that allows the repair of damaged nerves in nematodes. The study is from Science Express. A gene that can stimulate the growth of nerve cells was first identified by researchers at the University of Utah (USA), thanks to cutting-edge experimental techniques and a huge genetic screening on a nematode (cylindrical or worm). The neurons, which in the embrio are able to regenerate, in adults have their capacity to "repair" reduced or absent. In other words, damage to the central nervous system (brain or spinal cord) and its consequences - paralysis, loss or reduction of cognitive faculties - are permanent. "In the past molecules have been identified that can inhibit the growth of neurons in different organisms," says the coordinator of research Michael Bastiani, "but their removal in the laboratory had no effect. That is why we went to look for those genes that can stimulate rather than inhibit, the regeneration of nerve. " Taking as a experimental model flat worms (Caenorhabditis elegans), biologists have searched for the genes that trigger the regrowth of motor (neurons that "command" voluntary muscles): in practice, with an experimental technique called RNA interference to "shut down ", one by one, 5000 on 20,000 genes in the DNA of worms (genes similar are also present in humans). The analysis led to the identification of dlk-1, which appears to play a key role in the regeneration of nerve tissue, and three other genes responsible for the formation of axons (parts of the neuron that conduct electrical signal). The researchers found that in nematodes, the gene dlk-1 not only triggers a chain of events known as "Map kinase" behind the growth of neurons, but also that their regeneration can be increased or decreased by stimulating the gene to produce amounts more or less high of the protein dlk-1.

The switch that turns off and on to command the superconducting property of the new device is a trivial electric field. In practice, what has been done by Andrea Ankle and colleagues at the University of Geneva in the first superconducting transistors. The operation, represents a milestone of applied physics and paves the way for the development of a new generation of microchips - and therefore computers - much faster than at present. To understand how and why the device is considered so promising it must be from another discovery, made last year by the same group of university research in Switzerland and published in Science. In one study, physicists have created a single crystal in which two metal oxides (strontium titanate and lanthanum aluminate) are separated. Between these two materials, researchers have found a layer of free electrons (electronic cloud) and 0.3 Kelvin - that is just above absolute zero - traveling without any resistance. At that temperature, the crystal becomes a superconductor. Scientists have now discovered how to turn off and turn on the superconductivity of this crystal at will, or modules, simply by applying an electric field to the point of contact between the two oxides. The result is a version of superconductive field effect transistors (FET) devices known in applied physics, able to switch from one state to a semiconductor insulator, and basic digital information in electronics (the fact that the current can pass or not is used as a binary 1-0 to store information). As the field effect transistors is a semiconductor, however, it always has resistance to the passage of current. This means that the speed at which you can get the electrons when the device is "on" is limited which means heat develops beyond a certain limit. This side effect is damaging the transistor. A superconducting transistor, however, can pass electrons (and record information) much more quickly, as it does not oppose any resistance to the passage of current and, therefore, not heat. There remains the problem of extremely low temperatures required for superconductivity. A limit that research is a long time trying to overcome.

A highly resistant and self lubricating material has been discovered, thanks to the formation of an oxide surface that captures the water vapor Hard as diamond and slippery as a sheet of ice. The secret of the extraordinary characteristics of Bam, a special alloy-ceramics produced by blending a mix of boron, aluminum and magnesium (AlMgB14) with titanium boride (TiB2), was unveiled by researchers of Ames Laboratory, in Iowa (Usa ), who had accidentally discovered it a decade ago. In 1999, researchers tried to obtain a substance capable of generating electricity if overheated, when, unexpectedly, found in the hands a league owned by the exceptional and seemingly inexplicable. The Bam is tough, despite possessing a complex structure, asymmetrical and not compact. Moreover, says Alan Russel of Iowa University, it is inherently slippery. One characteristic that, according to researchers, could be due to the formation on the surface of boron oxide, which can attract water molecules present in the air.

An amazing material was developed by Chinese scientists which is composed of carbon nanotube films and has a possible application (among otther) to produce the world's thinnest speakers. Nanotubes, are a new carbon breed of material, which is 1000 times smaller than the width of a hair and can give sound with the "same quality of conventional speakers". This, however, does not require magnets of any sort or moving parts for that matter at all. You can easilly imagine speakers everywhere: on walls, helmets, thinner ear plugs or even on your shirt. This is possible because very thin carbon nanotube films, with the right frequency of electric currents, can emit sound. It also has a wide frequency response range and high sound pressure. It also turns out that they are practical to build, and are even stretchable. Here is a video with the actual speackers embedded in a flag!
