Solve the Flywheel-IVT Problem with This Simple Solution in 15 Seconds

In summary, this problem seems to be centered around understanding momentum and energy conservation. It seems as though there might be a problem with the calculation of torque, based on the incorrect assumption that momentum is conserved.

RonL: You just described our second generation 2-flywheel system. Exactly on target. If you search some of my previous posts you'll see how long I have been attempting to nail the mathematical analysis.

Kinetic power LLC has developed such a system (built and working) utilizing 2 variable-inertia flywheels, each coupled to a motor-generator as well as the epicyclic differential. My goal has been the performance modeling. My background is electronic engineering and obviuosly have been struggling with the math concepts, however with the recent inputs from this forum I believe I'm much closer to an understanding of what is happening. Thanks to all!

Thanks jimgram, that positive comment came at a really good time. :)

I will look at your post and for the company website.

I have looked at all your threads and post's in them, it seemed that in post #10 of "conservation of angular momentum" the full impact of just how much energy is in store became clear in your mind.
The name Kinetic Power, LLC. did not turn up anything that seemed to go along with this topic, do you have anything more, or did I get too close to the patent in process that is being worked on ?

RonL:
Actually, our patent application was recently published so we will be bringing our website up soon - as of now you are correct - there is no public info available. You are also correct about the understanding of angular momentum - I needed to visualize the whole system in the absence of earth-based physics (I.E. in space). It's still a problem however: I see that torque is applied to the gear housing and that dL/t = torque. L is I*[tex]\omega[/tex], so, it doen't matter how you assume I or [tex]\omega[/tex] for the conservation of momentum, but matters significantly with regard to the conservation of energy.

Thanks, I will be looking forward to a web site.

I have gone through the thread again, I'm a little embarrased that my post seems to parrot your post #30. I don't understand the math of the pdf in post#13, but I think I understand the problem.
I would like to throw out one of my observations from years of thought processing (and some actual bench testing) based on counter rotating flywheels, when the physical mechanical contact for energy exchange is removed you will find the efficiency to improve by a great amount.

A question about what I think is going on, and what I think most people fail to consider, or just overlook, would be...If power is added for an amount of time that brings a flywheel to it's maximum rpm, the kinetic energy has grown far in excess of the power used to bring it to that point, is this correct ?

It seems that most rebuttals to flywheel energy storage is, a cycle expressed as zero to max, and then max to zero, which will of course leave an overall loss every time. Cycle time at peak rpm is the most important thing.

So to me the total energy exchange between two interacting flywheels, if using only gas pressure and electromagnetic transfer, will result in the most efficiency possible.

The perfect system, as I have in mind, can come with a NDA and the price might be far cheaper than you would expect.

Jim, thanks for your threads.
