Hi Robert, just a quick reminder about variable transmissions, in the mid to late 70s Daf/volvo produced a little car with this variable transmission the Daf 66. This little car was around for some years as i recall. I remember working in a scrapyard in them days and we had broken several them the old belt variable drive which was so different at the time, just thought you may be interested. Very informative and interesting videos most enjoyable.

THANK YOU! i'll have to think about how i might be able to add it in. in my application, a further addition of a simple pendulum linkage could adjust the gearing automatically based on the elevation gradient. all mechanically controlled. wild and amazing! thank you for being such an inspiration Rob!

I liked the angle shifting transmission mechanism that was shown earlier. That would probably be compatible with the spring-loaded tail assembly dampener of the old Aeromotor type mechanical windpumps. However, I'm not sure if one would want the demand to control the transmission, or the supply. The variance in supply on a windmill can change very quickly.

Hi Robert, I live in rural South Australia, and I have both solar and wind. If I had wind only I would need a massive battery bank to bridge the power divide. My 15 Kw solar array charges my car runs the house and charges my 8 kw battery bank. Even a massive turbine wouldn't be cost effective as my wind resource is just too intimiternt, as you say it's horses for courses, the best solution for me was cheap second hand panels and Lifepo4 batteries. The wind comes in handy on the occasional night when wind speed is high. It's about one night a month. Love your video, all the best, one old tinkerer to another.

In the 1970’s a TV show air in Sydney Australia demonstrated a ACVT that was a liquid. When a voltage was passed through it it would start to become solid. The liquid was placed between two plates. One plate was the drive plate and the other was the driven plate. With no voltage applied the driven plate will not turn when the drive plate rotates. As the voltage is increased the liquid becomes more viscous and the driven plates starts to turn. If the weight placed on the driven plate is too great the liquid “breaks” marginally, the driven plate slows. Increase the voltage the liquid becomes even more viscous transmitting more rotational effort from the drive. Eventually, the voltage passing through the liquid causes the liquid to become a solid and totally variable. The weight that could be lifted, pushes or pulled is relative to the diameter of the plates. It showed a demo of this ACTV device connected to a crane it was able to lift and hold a 1 imperial ton load. The other advantage was it ability to dissipate heat be cause the liquid surrounding the two plates was still a liquid and thus easily cooled via a radiator. I wonder what happened to it.

Sorry to rabbit on, but it occurs to me that if a system had two stable fluid transmission systems, one with a shear thinning fluid, and another with a shear thickening fluid, it could be dialed in to be self-regulating on power output without any sort of external governor. If the fluids were immiscible, and had a density difference, perhaps they could even be contained within the same apparatus.

@@grunwode No, in simple terms there is just one container. The two plates are immersed in the fluid. Only that fluid that is between the plates is affected. A low voltage affects only a small portion of the fluid and,as the voltage is increased more fluid between the plates is affected. The fluid that is not between the plates circulates about the container from the rotation of the plates. The container is the radiator. The object is; the rotation of drive and driven is 1:1 that would equate to “final drive” with the differential would as it it is presently provide the final gearing as it presently does in motor vehicles. If driven plate is rotating slower that the drive plate, a greater voltage is applied to the plates. A sedan would have a smaller plate than a truck. While different levels of voltage would be available the car and truck.

Now that was what you made, but it applies to everything, even NASA made contraption, only the efficiency should be better. Let's use your 80 percent for this. That means there is a 20% loss. I am thinking like a VAWT and how it would use a transmission to go from vertical to horizontal. That transmission will induce a loss (in this example, that would be 20%). Wouldn't it be better to just go horizontal? I just think we are ending up with some really cool contraptions that in the end makes it less efficient and is a Rube Goldberg type mechanism. It would be akin to saving 10 mpg in a car, but it used 15 gallons more than just doing a direct drive instead. I understand the theoretical as long as chasing after it gets us to actually save more than we use with it.

It's the problem with friction transmissions. The reason you use a continuously variable transmission (CVT) is it best matches the rotor speed to the generator speed for all wind conditions so the loss in efficiency in transmission is often made up by the overall machine efficiency in converting wind to electrical power - bear in mind most wind turbines as total machines are only around 30% efficient - if you use a CVT that has a higher efficiency than a cone type friction transmission the efficiency can go even higher such that the total machine efficiency is raised above the total machine efficiency of just using a gear set - this is why automobile manufacturers are crazy for this tech

Looking at all the sliding, geared, racked parts made me think of a book I had (twice) that is actually not only obscure but the author really didn't want to write it. Antonin Svoboda preferred his treatises to be mind crushing pure theoretical logic, which is how I learned of him. One of my managers from a previous life showed me one of the manuscripts, photocopied (maybe even drum copied or faxed lol), which instantly gave me a headache. He smiled, and said "well you asked where I was getting inspiration for my designs/patents, this is one source but it's nearly unreadable". I noted the author and looked for works that I could kind of understand when I happened upon a Dover book (not an affiliate) that was clearly written in plain, easy to understand language (even if I can't comprehend 90% of the deeper math/engineering), so I picked it up. I loaned it to a mechanical engineer that was working on a wafer loader/handling design for semiconductor fabrication and never got it back. I found another volume at a bookstore that was part of a bigger series, hard cloth bound, with pullout nomograms, much nicer than the one I had although much less convenient to carry around and study. The text's title is Computing Mechanisms and Linkages by Antonin Svoboda There are a couple copies on archive dt org and I apologize in advance for your lost hours because I can barely read the thing and I still spent months staring at it until the book got packed somewhere in a move. When I can finally understand more of it I'll get another copy because there's nothing quite like it. If I say any more I might spoil some of the surprises so I'll stop there.
