First PEGASUS EXPERIMENT

[stealthyaroura]

Robo at what temperature does mercury turn to vapour? Is it less than what the steel container will melt at?

The use of the rose bud and gas is needed maybe oxy/acet? Or what about an electric hot plate like one of those portable cookers? They get red hot.

Anyhow good to see you had a go. Very cool. Gold for effort.
Keep us posted.

Im kinda considering it.

Having a hard time getting a torch right now.mercury vaporizes and turns to plasma below steels melting point.

[stealthyaroura]

Thanks mate, hey there's no rush is there.
I found that out myself with the stubblefield coil.

Thought I would have that licked in a week, boy was I wrong but that's not what matters is it.
Cheers.

Do you have any way of measuring the temperature of the mercury or of the air inside the container?

GUYS, Thank you, It makes me feel much better that my own project seems to be taking ages. :c)

IF the UK guys want a high voltage probe search ebay for HVP-40 there's one for fifteen quid.
If someone else doesn't pick it up soon, I'll have it for my second scope. They are usually 50 upwards.

Here's the link:

high voltage probeooooh kinky hehe.

Nah I don't do pressure fruitbat me 'old chum things get done eventually.
The worst thing you can do is put a deadline on a project!

It just takes all the fun out of it and mistakes get made.

No way to take temp inside vessel.

No way to take temp inside vessel.

Is it possible that the heat is being dissipated by the container's wall and not enough reaches the mercury?

Sure you can, you just use a standard 'PT100' thermocouple probe, in this case one covering 500C or whatever that is in Farenheit: I'm not going to do ALL the groundwork for you but these probes are equal to 10mV= 1deg.C or something like that, so you can read them directly with a multimeter

Just a quick line to thank Luke for the 'Electronics for dummies' thread.

Just what the Doctor ordered - for me

..About time i went public with it...
Some kool updates coming soon, promise

Do you have any way of measuring the temperature of the mercury or of the air inside the container?

You do if it boils.  That would make it 357 °C less a little depending on the pressure.  I'd expect it to explode but I haven't followed the entire thread.

Is there some reason why the engineers here think the thing won't blow?

Stick a blow out plug in it less than the strenght of the steel. Worst you will get is a flat tire.
I would not start with a full tube of mercury. Keep adding it until you get your results or the plug blows and work it from there. In the states we like to break it till it works.

Weld a chain to that plug otherwise it could become a bullet. Don't face the plug in your dirrection when testing. Keep the weak part away from you.

Go Robo Go.........It will either fly or go pop. Record the heat in and the amount of mercury inside. If it blows then empty 100% and start again.

A quick test of this might be to get a regular gas stove with a high heat round burner. Take a circle of tube that is the same size as the center line of the flame and place it above the flame. It will do 3 things.

1) nothing but get hot.  Not enough heat or mercury
2) Blow out the plug(s)
3) Fly away

IF you are going to have pressurised mercury vapour flying about, then I'd seriously counsel some Proper Planning before you fire that bad boy up, around the issue of not breathing it in.
