Puluj ( Crookes ) Tubes - windmill and radiometer

Puluj Tubes from around 1900 working. The heating action of the electrons makes the paddles go round in the same way the heat from sunlight makes a solar radiometer turn. These would commonly be called Crookes tubes, more correctly they are called Puluj tubes in all the old catalogues.

where might one purchase this fine item

[AlastairWright]

They're rare antiques. I've seen three for sale in the last decade and the last one sold for a lot of money.

[AlastairWright]

Yes they produce some X-rays. I doubt the modern reproductions use leaded glass as it fluoresces blue and all the modern tubes I've seen fluoresce green.

The trick is not to run the tube for long, keep the voltage to the minimum and operate the tube from 6 feet away.

[AlastairWright]

It was proved by J J Thomson in 1900 that the wheel is turned by the heating action of the cathode rays in exactly the same way sunlight turns a solar radiometer. He calculated that the electrons alone would turn the wheel about one revolution per minute.

Looks like somthing from a mad scientist's lab in an early sci-fi movie. But serioulsy, I think that is cool. I'd love to do my own high-voltage experiments, but I'm sure I'd kill myself.

your home must be like dr frankenstein's broodwar.

spiffy colors, got to love them antique gadgets

[giakful]

I would love to have this object. where can I buy it?

[MrGoogfan]

That's beautiful.

I'll just scoot right into this...as i read through this debate, both sides seemed possibly valid, but you ruined your comeback with the "we'll have some intelligent discussion". That was an intelligent discussion, unless the definition of one is when you are right. Douche McDouche

where can i buy one of this?

[flick2040]

I would not have thought of xrays being produced. If i was in the same room as this machine I would be tempted to get some lead and film to make a poor mans dosimeter.

way cool though.
