Hello from Detroit Michigan USA Great video Brother thank you for sharing your knowledge and expertise and for taking us on your adventure Into Science
You're an inspiration, Robert. Seeing that curiosity of a child emerge when you experiment always puts a smile on my face. Your videos are extremely informative and easy to replicate. Thank you!
Mercury arc rectifiers are amazing if you know what they are capable of. Did you know they can convert AC and DC at high current, at the same time. That's pretty damn remarkable.
Rotary Hg vortex based systems (iron based ring magnet) could actually provide turbine driven version. They do have sime safety issues, however most of these can be reasonably addressed with rational design of housings and safety mechanisms that can contian spills in worst case scenario. Ironically a graphite sleeve filled with molten sulfur would allow these to both contian Hg in the current standard SOP for spills (sulfur powder or activated carbon), while also allowing solar heated graphite to liquify and store large temps of up too 400°C + around the glass housing wall of the rectifer. Hg is getting pricey.....but its a self regenerating electrode. In theory they should last forever and you can do way higher voltage/current density than most other known systems.
Another early rectifier loved by ham radio operators in the 1920s was the baking soda rectifier, being wet no doubt it was messy but very easy to make too.
rectifiers have interested me for years . i used to do odd work for a paper/ board mill the old m/cs ran a400 volt DC fed hrom an enormouse mercury arc rectifier the sound and light show from it was somthing to behold . i have worked on vintage black and white tvs that used selenium rectifiers and when they went bad well the smell is somthing you will never forget.
I would suggest taking your mV output and translate that into kinetic energy. Look to Lorentz force. Lorentz also induces rotation. Take a conductive rod and send current through it, within a stagnant magnetic field and you'll see the rod rotates. There is no commutation involved. The conflicting fields resist each other causing rotation/torque.
Robert, could you try this on alpha wire (~50 μm), and sputter on magnessium. Small diameter wires with an Mg-OH surface should in theory be able to be scavange thermoelectric work in hot fuids or steam when woven into braided cables and insterted into pipes. Being able to put this into heat pipe could provide large output when contextualized aginst the large thermal work loads even small and inexpensive copper heat pipe systems typically handle.
I wonder if a nano sphere creation process, similar to what Nighthawk Light described in his creation of his cooling paint would be possible here and if it would offer any benigit
One open question I have.... Given the heating method here vs. traditional publications from back in the day; is there carbon being composited on the copper wire?
Hey Robert, can you do a real life stress test on your 3d printed stackable gears? I want to see how long they last at a constant rate till they start to show damage.
Great vid Robert 😎👍 if you had a small tube with copper terminal caps filled with dry (or maybe in suspension) copper nano particles and ran your magnet rotor past it would anything happen?
So, how do thermal couplers work? When a flame such as a piolet light keeps it hot, it will allow a gas valve to operate safely so it will not open if the piolet goes out. when the appliance calls for heat and the piolet is out?😊
Hello! Is not about the video but i'm thinking.on making a Gravity battery and my idea is that i use a 12v dc winch, the cheapest on the internet, i'll use to raise the weight and then lower it and because is a dc motor i sholud have some energy back, that my plan but i haven't tryied yet and i'm sure is not that easy, maybe the winch Need some modification or maybe the gearbox in the winch isn't good for this job, anyway if is an intresting idea pls give us some advice it would be really usefull thx
This bloke is full of the proverbial, and clearly has a lot of people fooled. Most of what he comes out with is pure twaddle, and the rest he gets from Google. I was an electronics engineer when he was in nappies, and I wouldn't let him loose on a crystal set.
"90% of our electrical energy is provided as AC and there are 3 good reasons for that...." Yeah it's called L1, L2, L3 😀 Just a taunting the over-the-pondies 😛

some of these were still in use just a few years ago for electric trains (subway)
@@davestorm6718 a couple still are. But they're private.
They look so unreal have a search for this "Kempton Steam Museum - The Mercury Arc Rectifiers"

This is the same power supplier for use in WW2 transmission transceiver Robert. A very interesting part of physics. Nice video fella too.
That's wonderful content Rob. I can't wait to make one ! Rectifier here I come ! 👍🏻
Great work, thank you Robert and have a nice weekend
Thanks, you too!

Your nolage of science chemistry is crazy . My head is still spinning like the dc motor love it Robert thankyou.

your videos are getting more and more interesting every day
Thanks. And very interesting, the old TV were DC powered I think by selenium 10 diode rectifiers just before germanium types.
Could you form thin plates, or even coated pieces of glass or plastic, in order to generate electricity through the heat from the Sun?

Is that an alcohol torch ? Great videos, we really enjoy them here in Missouri.
Thank you for this interesting episode of Indiana Jones and the Lost Rectifier.
Really like this thermopile application. Isn't this a diode? Would it work even better at producing dc from ac current as a full-wave rectifier?
Blessed are we with peeps as u Rob! Does not the flame offer capacitance though? More training u need.
Fascinating
AC power delivery over long distances can be less efficient than DC (corona discharge and skin effect) given the same wire diameter.
you could use aluminium sulphide but it would stink.
Old rectifier resurfacing 🤣🤣🤣
Led ,capacitor, ambient heat .....version ....??.Peltier and thermal shielding.....more learnings!
An off the wall question for you Robert. In your younger years did you study Nomenclature?
One open question I have....
Given the heating method here vs. traditional publications from back in the day; is there carbon being composited on the copper wire?
Should have worn the Dr Who outfit when you started talking the chemistry stuff : - )
If you ever smelt a blown selenium rectifier you'll never forget it
Isn't "smelt" a fish?
I'd've liked to see a close up of the wire.
They are Thermogalvanic cells.
Hey Robert, can you do a real life stress test on your 3d printed stackable gears?
I want to see how long they last at a constant rate till they start to show damage.
are those 3d printed sound dampers? very interesting

Wow, thats awesome! Cool proof of concept and shows how easy it is, just how does the specs look like for such a rectifier? What are the limitations?
👏👏👏👏👏💎🌎💎🔆🙏
Whats copper oxide like for storing hydrogen 💡🤔
Very !
Nice
But can you make a transistor out of it????
I was here first! 😂😂
How can we know the average forward voltage of the different kinds of diodes you showed?

@thinkingandtinkering Thomas Townsend Brown
Did you ever investigate this further, Rob?
yes - there are more video on this
@@ThinkingandTinkering Looks like I'll be doing another deep dive into the channel. For this and the A4 paper battery too.
I have an idea about powering train engines generating electricity on the boxcar wheels. Reply if interested. Thx
