That's freaking awesome! A masterpiece of engineering.
WHoa! That's crazy!!! Sounds like it could be dangerous! What type of temperatures and pressures do you see sodium liquify?
Or is it a sodium solution? What is this load most commonly used for? Would this be a regularly used piece of equipment for industrial processes or is it a purpose built scientific instrument?
Perhaps it is a top secret scientific tool used to tune some sort of direct energy ray beam weapon?! Somehow the massive power capability just screams nefarious destructive usefulness! Hi!!!
I like the copper plumbing, it looks pretty cool too. The plumbing isnt what is carrying the sodium is it?
I don't know any hams who could afford the power bill.
It's a solution of Sodium and potassium, NaK, which is liquid @ room temperature.
Yes, the copper plumbing carries the solution.
If it were a pure Na solution, there would be an immediate explosion at the pressure gauge connection, which is wrapped with Teflon tape sealant.
pure Na is highly reactive with many common elements/compounds.
The only pure Na coolants (to the best of my knowledge) that are currently bring used as coolants are in "fast"or "breeder"reactors.
Due to its high boiling point, Na allows the reactor vessels operating pressures to be much lower than while using conventional coolants.
Na-23 has a low neutron absorption rate. when it does become radioactive, it forms Na-24 which has a short half life of 15 hours before it decays to harmless magnesium.
I think I'd push it to, say, 20 watts.
It's like automobiles: If you have to ask the price, you can't afford it. Most hams can't afford it, but some own a Rolls-Royce or Bentley without bothering to ask the price first.
If they OWN (and use) a 500 kW transmitter, the cost of operation won't bother them.
Many of today's HF amps are quite capable of producing a clean 2,000 to 2,500 Watts. That seems to be the new speed limit anyway...
I would still only put out 300 watts
The Alpha 8410 and the Ameritron AL-1500 come into mind.
I would stick with what I usually run, 100W. When rare DX comes up, I seriously doubt any amps capable of running well over 1.5KW are not already doing so. Look on a scope some time.
Going from 1K to 1.5K won't make that much difference on the other end, but it certainly would push some other peanut whistles out of the way for sure.....
