... DICK: Congratulations, and pardon my jealousy! 25" arcs from the top & sides...WOW! I guess my failure is that I don't have an involute opening to my 30" ...
Hal: Before you try the bowling ball caper.......If your terminal polarity is (+), try running the the VDG reversed with the terminal (-). The reasoning:...
Dick, Do you have an theories as to why terminal polarity changes performance? That is very interesting and puzzling to me. Also, I have never tested the...
DICK: Since my Bonetti (and VDG) interests are temporarily on the back burner, all I can say is that I believe Prometheus has a positive terminal output. (I...
Paul: My original VDG uses nylon bottom, teflon top. Zeus uses nylon bottom PVC top. Both have negative top terminals. If you have a 0-50uA meter, remove the...
Hal: I have tried pumping both Junior and Zeus with a 10Kv 20 ma bridge rectified oil burner transformer with aluminum rollers at the bottom and non...
DICK: Perhaps the inefficiency of transporting Proton charges may be due to the fact that a Proton is almost 2000 times as massive as an Electron. (1840X to be...
Hal: Certainly, in your case, it sounds easier to set up the pump mode than to flip polarity, at least for initial evaluation. The original VDG at the MOS uses...
Anyone know of some cool computer program to simulate VDG's? Preferebly Java, Open Source, Linux, Mac OS X, or UNIX as I can run them but not a Windows program...
Thanks for the FYI. My latest VDG uses a 6" belt of vinyl impregnated nylon, 36" diameter spun aluminum sphere, 8" dia 1/4" wall white PVC column. Sparks...
... due to ... Proton ... Hey Steve: You mean you can't charge the VDG with protons? I've heard of cyclotrons accelerating protons into an energetic beam for...
Hello Derrik, I would agree that building a Cyclotron at home would be more than cool but I'd hardly refer to a $15K+ project using a multi-ton magnet as...

... The Amateur Scientist was a great column from a time when Scientific American was great. One of it's editors, Jearl Walker, is a professor at Cleveland...
Dr. Resonance states that leakage losses become substantial with PVC columns over 8" diameter. I made a "non-scientific" test with my VDG "Prometheus" (see my...
Hal: If my pourous memory serves me correctly we discussed column material some time ago and I think one of us asked the good Dr. deQueiroz about the exact...

Hi, I'm new to the group, and had a few questions/thoughts: (1) After wandering around Home Depot for hours without success, I am wondering if somebody has a...
I'm sure others are the group will have useful advice for you, however I guess I get to take the first stab at it. 1) If you are making a smaller VDG rod is a...
HEY, MARK & TIM: Without a lathe, you simply can't depend on your shafts to run true, and your rollers to be accurately aligned on your shafts. If you don't...
Hi Mark & Tim: Welcome. Addressing your questions as you listed them; 1. Rollers - I am using a bottom roller of solid nylon, bar stock purchased from...
Whoops, sorry about the blank message. Materials choices all depend on how big a machine your making. I made a modest machine with about a 16in terminal. I...
