i need to create a source of several hundred thousand volts DC or greater, what would be the best approach to do this in DC?
Click For Summary
Discussion Overview
The discussion revolves around methods for generating high voltage direct current (DC), specifically targeting several hundred thousand volts or more. Participants explore various approaches, including voltage multipliers and alternative systems for converting AC to DC at high voltages, with a focus on applications such as charging capacitors and experimental setups.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant seeks advice on the best approach to create a high voltage DC source.
- Another participant inquires about the output specifications, including current and power requirements.
- A participant mentions resolving their issue by using a voltage multiplier and high voltage power source, emphasizing the need for high current and the challenges of converting AC to DC at high voltages.
- Suggestions include building a multi Wimshurst disk system powered by a small engine, with details on construction and balancing for effective charge generation.
- Pellettrons are proposed as another potential source of high voltage DC.
Areas of Agreement / Disagreement
Participants present multiple approaches and suggestions without reaching a consensus on a single best method. The discussion remains open with various competing ideas and techniques proposed.
Contextual Notes
Participants express uncertainty regarding the efficiency of different systems, such as friction-based methods and the effectiveness of AC to DC conversion at high voltages. Specific assumptions about the application and design requirements are not fully detailed.

What are the output specs? How much current & power? Who you going to zap?!

tis okay, problem sorted, thanks though, using voltage multiplier & HV power source, need as much current as possible you see & turning AC to DC at HV is difficult, & friction based systems seem inefficient-not zapping anyone except myself maybe, just for charging capacitors, am intereted in these 'crazy' gravitomagnetic experiments

Try building a multi wimhurst disk set ran by a little 4 stroke RC engine used in model airplanes. .049 cu. in. to 1.2 cu. in. (80cc to 20cc)
You can increase the RPMs of the Wimhurst disks by attaching an RC transmission to the engine.
Build the Wimhurst disks from round and balanced PC Board and setup the Wimhursts with thin stainless steel plates glued on by industrial epoxy, You can use the RC's Magneto to charge the Wimhurst plates to generate your charge potentials alone with any additional circuitries.
Must be very balanced and is rather noisy.
Electric motor driven Wimhurst disks is another option.
Pellettrons are another good source of High voltage DC.
This is the only advice I have to offer.
