Do any of the bigger FP or CP birds have the traditional cabin style?

Now if only mine would arrive...I ordered it from Heli-Pal on 8-1-12.

Somehow Hal - I don't think that power plant is going to fit into the BL.

I dont know, I've picked up some pretty heavy stuff with mine. Maybe not a Tesla Coil but it did carry my ipod aloft so I could look down and see if my gutters needed cleaning.

Well, that ain't no Tesla Coil!

I don't build Tesla Coils anymore because their primary excitation voltages are lethal, and I've managed to avoid electrocution over the past 60 years that I've been building 'em, so at age 76, I'm through with Tesla Coils!

Pictured is my Van de Graaff Electrostatic Generator. I designed it for a discharge of 1.16 million volts in stored direct current energy.
Direct-current discharges in this scale are harmless.

The belt is driven by a 1/4 HP motor, and the terminal sphere is 30" in diameter, formed in two halves at a metal-spinning shop.

In practice, my yield was only about 600,000 volts because of extreme coronal losses at the column's entry into the sphere.

Because of its potential for discharging through the ceiling of my game room, I dismantled it, and now the column and sphere are a garden ornament!

Heres what it looks like so far.

So its like a giant capacitor? Store and release all at once? What ever it is it looks impressive. Bet it was fun to build.

That's right, Tom.....a Giant Capacitor!

The discharge energy was stored as a capacitance between the sphere and the discharge electrodes alongside the generator.

When the voltage became sufficient to ionize and break down the air gap, then a discharge would occur, with an energy equal to 1/2 CE squared.

Thus, when the voltage is doubled, the energy is quadrupled!

Tennis, anyone?.....

Tom the fuse looks good! Now if we can just find the darn right decals Confused

Hal I received a mild electrical shock just looking at that thing! Laughing

That's due to induction, Tony!

Here are a couple of commercial Van de Graaff machines. The larger one will yield 400,000 volts on a good day with low humidity; the smaller one about half that. Fortunately, here in the High Desert our R.H. is always pretty low.

The other tall item is the ground terminal that the discharges arc to.

I improved the big machine by replacing the sleeve bearings on the upper pulley with ball bearings.
