Sorry for your loss. Thanks for all you do

[StephenWells]

I'm a subscriber and watch your videos regularly. I noticed the photo of the lovely woman behind you and gather that you suffered a loss. I'm sorry for your loss. That's a lovely way to remember her.

We love watching you show us stuff! Your reaction to things makes it enjoyable because you find such joy in science. So sorry for your loss.

Thanks for being awesome Robert, so sorry for your loss.

First thing that comes to mind is a solution to wind wall problems. One of these on each column with an intermediate gear between and you would have additive torque for each pair of columns at an average speed. I can see real potential there as a solution to many issues with turbines and wind walls among many other things. My grandson is currently in his school's program for advanced health education. This does include use and creation of machines that improve surgery and treatment. I think I'll pass this video on to him as an issue right now in robotic medicine is a robotic stitching machine which is difficult to get two or more feet of the machine in sync to walk/pull itself across a wound without a lot of processing. I can see this as a jump off point for something like that. Who knows, but any solution might beat what is currently a bad one. With your blessings of course. Thanks Robert! I am kind of a clockwork nut, so this is something I really enjoy. Appreciate the videos Robert, please continue. Thanks again!

Hello Robert, every time I'm having a lull with my wind turbine project, ( Pardon the Pun 😁) you bring out another video that is very inspiring and gives me so much ''Food for Thought''. It's all very educating and taught by a great teacher. 💪👍

[DraugaDae]

Always enjoy watching - its wonderful to have your videos appear in my feed.

Hey Robert.

That setup is used for local speed variation in chairlift stations, it's known as the "cadenceur" and is used to combat detachable grip chairs and cabins slpiing and changing relative places on the cable. It's a fun mechanism.

For your uses, though, it still has slip, and if you want overlapping savonius turbines, the solution with the least loss would seem to me to be to gear them together and take a feed out somewhere.

(edit : the "its known as" refers to the part of the chairlift, not the mechanism itself, which is just a dual-driven planetary drive)

Nice to see your videos popping back up in my feed again. Welcome back, I hope you're well...

Much love, from somewhere in England.

[mbunds]

Thank you for another fascinating production! I always wondered how blade count affects output.

[daveh]

I'm loving mechanical mathematics, differentials got a whole new part of my mind working. Just toying with a slight logarithmic multiplier by driving the planetary axle with a heavily stepped down ring gear (simulation only).
Nice picture of Patti BTW.

[maddhattlizard]

I love watching your videos. I just got back onto the internet last year, so I'm glad you're still making them. My heart is with you.

[tamarhuard]

I love Robert, please continue to share your mind....

[BalticHomesteaders]

This is a nice gentle nudge that I really need to get on with making some wind turbines and generating some electricity 😊

[Pystro]

You actually DON'T want a differential in this situation. In order to overcome the low-torque phase of one wind turbine, it has to stay lined up with the high-torque phase of the other turbine (and vice versa). They _HAVE_ to be locked together, not linked via a differential.
Which is why stacking the turbines on top of each other is such an elegant solution: It's the easiest way to lock them together.

[TheElectronicDilettante]

For the vertically oriented, colorful vanes you showed rotating in opposite directions, you could use the planetary setup used in aircraft with ContraRotating Props but instead of have a static coupling, introduce a roller clutch around the cage of the planetary assembly. What’s more, for a vertical configuration, they would be very easily stackable to allow for more vanes to be attached.
Then, as suggested by another one of your viewers, use a hydrostatic type drive to transmit the power to the generators. You can also get a lot of torque multiplication using hydrostatic drives.
There’s a view printable models of the contra rotating propellers on Thingiverse and Printables if you need to see it in person.
Awesome video as always. Thanks

[DudleySmith-htnr]

Again, a different perspective of the use of compound planetary systems. Always thoughtful.

[arielmarshall]

Thank you for addressing this, I look forward to seeing it develop. I do not think I saw your cvt video, so I had no idea that variable transmissions came in this form factor. Hopefully I can share my version with you and your viewers also soon.

People sort out problems quicker than companies or government - keep up the good work 👍

[rikkiesix]

My condolences, now i understand why there were less videos. Be strong. Love your videos man
