Probably one of the more underappreciated or unknown parts of your influence is not only paying a craftspeople for their work but also showing off many wonderful artisans and small businesses who craft by hand. Keep it up, Andy!

In the examples shown the fabric/leather was almost always in contact with the glass and the comb was a consistent distance as well. Your machine has a lot of wobble to it, meaning it's not always in contact with the fabric so you only get a little charge each rotation, similarly the cylinder is often far too far away from the comb to actually transfer the electrons (at least until the voltage gets higher), that's why you have to spin it so much more.

i am also like 99% sure his leiden jars were barely functional (if at all) as well. the metal rod did not properly contact the inner foil nor was the outer foil connected to ground (or rather the felt) and on the water filled one you are supposed to fill the inside with saturated saline and wrap the outside in foil, or actually you can also place your jar into a second slightly bigger jar also filled with saline and just stick your contacts into the saltwater. the actually important part of the leiden jar is that the glass creates a thin insulator between two conductive materials holding opposing charges. saltwater is just a convenient way of having something conductive as close as possible to the glass so that the gap between the two conductors is as small as possible. the glass serves as dielectric aka insulator to allow the two "plates" of the capacitor to get closer while preventing a discharge between them. you can build a capacitor out of two metal plates and air but its maximum voltage will be limited by the air becoming ionized between them to the point where a spark strikes and the opposing charges get equalized.

I liked this episode. Really good to see the team colaborate with the glass blowing workshop, and the museum. Also, Andy's woodworking is looking so well polished compared to the start of the series. Such a great evolution.

To me, one of the most interesting quirks of history is that, though the materials and techniques required have existed since antiquity, the principle of electromagnetic induction (that passing a wire through a magnetic field produces a current) was not discovered until 1831. It would be quite easy to imagine an alternate history where this was discovered by the ancient Greeks, Romans, or Chinese, and the step from an electric generator to an electric motor is trivial. Perhaps the biggest limitation would have been the lack of supply of metal for wire?

The comb needs to be a consistent distance from the jar. I think that would help. It just means that the spindle isn't centered and the jar isn't perfectly round. You might be able to fix it by making the comb hang rested against the jar, with a spacer (wood?) that leaves only the smallest distance between the collecting jar and the comb. That way the imperfectly round glass jar still works.

More importantly it also shows Andy's willingness to admit that he can't do everything at a professional level himself with the glass, and like our ancestors of yore, turns to professionals in their fields for more expert work (though he's no slouch in the crafting department himself, he's more a jack of trades, able to do some of many fields).

One thing I love about this show, is how honest they are about the more than humble beginnings of our technology. It puts things into perspective for me.

I've seen glassblowing before, but not one where they were explaining what they were doing. Very cool :)

Also for the Leyden jar, you want the glass to be as thin as possible, and the surface area of the foils to be large. In capacitors, the closer the two plates get the more charge is stored, however depending on the insulator, the less voltage. This is probably why the plastic one they used at the museum worked so well, because the plastic is much thinner.

​@KurtBlanken At 17:25 he demonstrates that the static generator is capable of charging the Leyden jar he made. I'm sure there was a lot of cranking that was not videotaped or included in the video. The Leyden jar has a limit on how much charge it could hold, and there is a point of diminishing returns where more cranking won't increase the charge stored in the jar. After this point any static generator could continue to run without producing a noticeable increase in charge. The quality of the static generator would mostly determine how quickly you get to this point. You can increase the charge stored by using more jars, for increased surface area, or by improving the design of the jar used. I suggested one way the design of the jar could be improved to hold more charge.

This makes me appreciate the old old masters, engineers and scientists a lot more than before. As we have it hard for our next step in development on any fronts from biology to engineering it was as hard for them even if we think now it is easy!

I like that you're allowing professionals now that you've unlocked certain aspects, like the glassblowers and blacksmith friend

We just finished covering static electricity in school, and air humidity plays a big part in it. Make sure it's not too humid where ever you are, that could make it appear non-functional.

Definitely one of the coolest and best finished things I’ve seen you build

For the Leyden jar with only water, you should try putting foil on the outside. Also salt the water. I did this and it held some crazy voltage.

I think the comb might be doing a coronal discharge, and making the points sharp might help.

I had a bad experience with Medtronic in the 80's. I interviewed for a job as a tech writer and was eventually turned down for it. After talking to a few other failed candidates, we realized that HR was collecting everyone's suggestions for how to improve the company's documentation and docs department, and then they used all of that to do the work in-house based on "free advice."

Very cool to see you getting into electricity! Some basic building blocks of circuits (batteries, resistors, capacitors, inductors and vacuum tubes) are not terribly difficult to make, especially with your guys' craftsmanship. I'd love to see you build a simple circuit like a single diode AM radio receiver from scratch somewhere down the road! Looking forward to the next video as always.

This is an early version of the Van De Graph generator which are a fun science demo! They refine the process to get the biggest charge possible for impressive arcs and hair raising ability!

It would be neat if you could show how early magnets were made. Iron bars aligned with the poles and being struck by a hammer impart some magnetic force to the bar. Done over multiple instances, you can get a semi strong magnet. Once you make one magnet you can make other by moving the bar in one direction over another bar, aligning poles. Once you get a couple you can make a basic generator and motor.

Nice, 4:52 this is the Teylers museum in Haarlem, the Netherlands. My fathers grandfather was curator in this museum. I remember my father telling that they at home jokingly referred to these Leiden jars as "grand fathers pocket batteries".

I wish there was a way of improving precision because I think that's where the majority of your "work" losses are coming from the inconsistencies in the rotation of the glass and the differences in the distance between the glass and the comb and reducing the efficiency of the system. the same can be said of the lathe. that being said it is overall immensely impressive you were able to get the results you have. I am not discounting the work that goes into your machines. Keep up the great work. I love the progress you're making.

And then to replace the laden jars with capacitors made with paper sheets and metal sheets. 4 layers, rolled together: paper sheet, input metal sheet, paper sheet, output metal sheet.

All that hand sawing made me think that for your next project you should reinvent and build a table saw to make future projects easier. I bet that will be a super safe project.

Make sure that the outer foil of the leyden jar is connected to ground, Also old time radio tubes used a glue made from a mixture of shellac and wood flour to hold the base on

I couldn't see it in the video but did you ground the outside of the leyden jar? cause grounding the outside would make the inside more willing to accept charge

Nice. You might want to make the glass jar run smoothly instead of wobbling, then you can get the combs closer and you should get a better static capture.

The Bakken is such a local treasure

For the water version of the Leyden jar you need to keep your hand around the jar to produce a difference in potential. + go in but without the - on the exterior the jar can't stock energy. The creator of the Leyden jar himself made that mistake by putting the jar on a piece of wax for nothing to happen. After multiple tries, he forgot to put down the jar and received a nasty zap after filling the jar with electricity.

At the voltage and amperage involved (high voltage, low amperage), wood is less of an insulator and more of a resistor. It can drain the charge fairly rapidly. Found this out when trying to build an electroscope in my teens. Using a wooden lid for my container rapidly drained the charge from the electroscope. Replacing the wood with plastic, or insulating the metal from the wood, produced much better results.

I’d love to see him reattempt the suit video with his new skills.

It might ruin the authenticity, but you could throw some bronze bushings in the holes to extend the lifetime of the wood on wood shaft and supports. Same for the lathe, if not taking an attempt at making iron/steel bushings for that.

You should try grounding the outside of the Leyden jar while charging it. Also, you should do these experiments in the dark so you could more easily see very faint static discharges.

Nice work, now to the workmanship. You need to remove the glue on the glass jar and try gluing while spinning in order to get it to be more concentric while spinning. The electron distance varies too greatly per revolution to get a consistent charge and the first attempt had the comb contact the glass ( returning the charge ) a few times. If you look in a modern Van de Graaff Generator, the comb is a set distance, from the rubber band as well as offset to be on the ' leading ' side of the rotation. The same principles are here so the comb works better before the center line of the jar. Considering this was a first attempt, it is amazing and love how well the wood looks with just walnut juice, olive oil an wax.

Andy , can you please do a video about your discipline and determination? You have more than everyone else

I have a suggestion to make your life a little easier regarding the generator. As you are using Glass, it's best to use Cat Fur (don't kill your cat, your local vet may have some by chance), it will greatly strengthen the charge you get.
