    emp vs pv panels..?

    Pv panels work because of the semiconductor junction like a diode or transistor.
    Does any one know for sure whether an EMP pulse will destroy a pv panel?[dunno][dunno]

    I dont know for SURE but what I have heard is that they would be somewhat similar to most other electronic stuff like computers and such in that a moderate EMP could knock them out. That said it should also be possible to put something along the lines of chicken wire around it to make a fariday cage for it so they could still function but be protected.

    Is there any way to make a homemade EMP device for testing purposes or is it like lasers where you have to have equipment which cost millions and need an entire building to work?

    anything homebuilt or otherwise creating that kind of a discharge would be outlawed by the fcc. I did see on the tele sandia or los alamos had built a reusable EMP generator for testing. they tested it on an suv like a "tracker" it killed the ignition / fi..killed it ded ( "d-e-d" dead)

    So it would have to be big in order to get the results you need to properly test with and if it's that big they will worry what you would do with it. Too bad. Used to be you could design stuff in your basement or garage, now you need a specially sanctioned laboratory and all kinds of officials watching over you and such nonsense. Shame when you think about it. Someone could invent an engine that works entirely off of salt water and someone would be there to make sure it never sees the light of day.

    Electromagnetic Pulse


    <table align="left"> <tbody><tr> <td>[​IMG] </td> </tr> </tbody></table>An electromagnetic pulse (EMP) is a sudden, high-intensity burst of broad-band electromagnetic radiation. The range of electromagnetic frequencies present depends on the source of the EMP. The high-altitude airburst of a nuclear weapon produces an intense EMP which, because of the relatively long duration of the explosion, contains strong low-frequency components (below 100 MHz).70 Conventional EMP devices built with explosively driven, high-power microwave technology produce a less intense, very short (nanoseconds) burst composed primarily of microwave frequencies (100 MHz - 100 Ghz).71 The range of the EMP effect depends on the strength of the source, as the initial electromagnetic shock wave propagates away from its source with a continuously decreasing intensity. The gamma radiation produced by a fission or fusion bomb interacts with the atmosphere, creating a large region of positive and negative charges by stripping electrons from atmospheric gasses.73 The motion of these charges create the EMP. The pulse enters all unshielded circuits within range, causing damage ranging from circuit malfunction and memory loss to overheating and melting. Militarily useful EMP can also be created by mating a compact pulsed power source (gigawatt range), an electrical energy converter, and a high-power microwave device such as the "vircator" (virtual cathode oscillator). An advantage of a conventional EMP device is that it can be triggered in a shorter amount of time, thereby putting more output energy into the higher microwave frequencies (above 100 MHz). Since modern electronics operate primarily in these microwave bands, the EMP produced by conventional devices is potentially very effective in shutting down electronics. Explosively pumped EMP devices such as the vircator have another advantage: it is possible to design them to focus their EMP in a particular direction. Even a focused EMP effect produced by a conventional device will probably have a lethal radius measured only in hundreds to thousands of meters, depending upon the strength of the power source and atmospheric absorption (particularly at frequencies above 20 Ghz). Finally, the USAF Phillips Laboratory has produced compact plasma toroids with energies in the range of 10 kilojoules.77 Directed at solid targets, the plasma toroids induce rapid heating at the surface, producing extreme mechanical and thermal shock as well as a burst of X rays.78 the X-ray burst can also be used to generate EMP. While theory predicts the toroids will be rapidly dissipated by the atmosphere, there may well be a method of delivering high-energy plasmas to the vicinity of a target that does not involve long paths in air. Capabilities:

    The few experiments with nuclear bursts in space have revealed that the size of the nuclear EMP effect is related less to the yield of the bomb than to the altitude of the burst. A 100-kiloton burst at an altitude of 60 miles would create damaging EMP over an area equal to half the US. At 300 miles, the same burst would create EMP over an area equal to the entire US plus most of Mexico and Canada. The gamma burst from a (purely theoretical) microyield nuclear device might be used to create a more manageable EMP effect. Electrical devices exposed t

    Well so much for my testing plans. Okay, moving on to will firecrackers end the world. Haha.

    Sandia has no problem generating kjoules..., ?I think the darkened city of los angeles may complain if you did it in your basement...I don't know, maybe a big batch of refried beans and a case of beer and enough effort and you too may be able to strip electrons outta' the atmosphere..Sounds like you got a bad case of "pinky and the brain" mwuhahahaha...

    Haha. Wait till I get up to prove whether the Big Bang really happened or not. Mwahahahaha. [LMAO] I have completely even forgotten the reason that I wanted to test anyway. I think I have CRS. It's not terminal yet. Haha.
