Good Afternoon everyone, Question: What are some effective ways to generate a high voltage (Multiple KV) using amateur equipment? I've dealt with high voltage before, so I'm aware of the safety issues. Anyway, here is what I've got thus far: If you go on ebay, and search for high voltage power supplies, you'll find two things. You'll find the really sketchy "1 MV converter for $7, shipped from china", or you'll find a few legitimate ones which, for the low price of $500 dollars, can generate up to 3 KV. Of course there are the capacitors, but they still only go up to a few hundred volts without spending hundreds. The other methodology I've looked at, is the ol' leyden jar method. Leyden jars are cheap, and if you have a static generator (Van de Graff or Wimshurst), they can presumably generate "quite a bit". My only problem with this method, is that I haven't been able to find any reliable way to predict/measure what voltage is actually produced...Not capacitance, but voltage. So, if you wanted to generate a few KV, what would you use? I'm leaning towards Leyden jars, but is there a way to predict what voltage you'll get before you build the thing? I know it changes depending on how charged it is, but how would one calculate the upper bound (Assuming one exists)? If I completely missed something let me know! Thanks in advance, Yours in Science, Kyle P.S. I'm about 90% sure this is in the right category (high energy...?) - If not, feel free to move me around!
