... experiment? ... I haven't, but after reading about the experiment I'll tune up the wilmshurst generator and give it a try. There are two outputs of the ...
Hello All, I had tried to create a 'solid state' VDG by using a negative Ion Generator. I placed the output inside of a sphere and let it run, but it never...
Hi Todd How big is the sphere, it may be that the charge you put in is dissipated by ionisation of the air, which I think will always happen even if there is...
Hi Elmer, I was thinking that unlike the belt which is a continuous DC power supply, the Ion generator most likely uses a multiplier circuit with diodes and...
The VDG sphere really is only charging up to the voltage the belt provides, no more... but the belt is a voltage amplifier. Pull two charges apart, the voltage...
Steve, I would have to disagree with your hypothesis on these three points: 1. If the belt were charging to the full output voltage then the rubber belt I use...
... The belt is not charged to the full potential at the bottom. It picks up a few hundred volts, then the physical motion of the belt carries the charge far...
Todd, Steve and All, Van de Graaff generator operation is through both increased voltage by separation of charged surfaces (the belt and the lower roller) and...
Steve, Don and all the members of the group, I would like to say thank you to both Steve and Don for their input, and to say I am sorry to Steve if any of my...
Hi Todd Explanation seems feasible, but I thought that pail effect is that it will continue to increase in voltage until the air ionizes. In that I mean, if ...
Trevor, I don't know so I am only going by observation, but when I run my big (to me) VDG I can feel the e-field expand around the output terminal but as soon...
I am a bit like you there Todd. Not actually sure, but you sure can feel that field as soon as you start your machine – even the small ones. The air, ...
Hi All, Well the humid season has arrived, and it doesn't seem worth it to run any of my devices. Well if any of you were wondering, the demonstration I was...
Hi Todd It has been a while since I have said anything – I feel sorry for people who live in the tropics as you have to pack up your gear for nearly 6...
Hi Trev, I live in Massachusetts, USA on the coast and while far from tropical we do get our share of moisture so I can sympathize. I forgot to mention that...
Thanks Todd I have the Perspex disc now for a year and haven’t done anything with them. Soon now I guess, but they are 6mm thick 13” Diameter. I think...
Hi Todd That's the place I got my Wimshurst Generator from. In fact I got one last year, and picked up another this year since as I thought the price was...
Hi Phil, It would be nice if we could use this humidity the way nature does, to make electricity. But I think my landlord would frown on thunderclouds in my...
Hello all, I'm new to this group and failry new to electrostatics as a hobby. I got started about six months ago when my daughter wanted to make a Leyden jar...
Hi Paul: Welcome on board! Sounds like you are really on a roll building stuff. Cruise the photo section to see what us folks are up to. Let's see some of ...
Hi Paul Welcome to the group. You are a tinkerer and like myself, love making things from old parts and scrap. You will find this group most helpful. They...
Thanks for the welcome. I found a very good book from Lindsay called "The Boy Electrician," first published in 1940. Loads of great projects and ideas, from ...
Hi Paul, I've had good results following advice from http://www.alaska.net/~natnkell/leyden.htm I use a plastic rubbermaid 1.9L storage jar, with a screw on...
... Yes, I found this site. Very useful. His cookie sheet electrophorus is very surprising and effective! ... I read in A. D. Moore about using the charge to...
I know this is geared more toward VanDeGraaff generators and such, but I was hoping I might get some insight on charging a capacitor. I started out wanting to...
Hi Troy, ... A properly designed voltage multiplier can work quite well for capacitor charging. For example, by using a number of identical lower voltage ...
If you are using a voltage multiplier/adder the output is allready DC at the output. 100kV you must be talking about a Cockroft Walton style adder. If you're...
I guess I should have clarified that, yes I am using a voltage multiplier. I am assuming that it has a standard recovery time. I'll look into that. What I am...
