... hi, For people who have trouble finding the above document, try: http://v3.espacenet.com/origdoc?DB=EPODOC&IDX=EP1368582&QPN=EP1368582 I think it works in...
... It sounds like it would work, but I'm having a tough time picturing it. Could someone who understands and has a mental picture make a sketch of what it...
Garth and Pushbeltman, thanks for the patent and link. The "heart" of this system is the "Pitch Transfer Gear". This “Pitch Transfer Gear" should be able to...

I hope to find just how efficient ECVT (like that used on the Prius) is. A manuel transmission generally have an efficiency of 95%, but it doesn't let the...
Thanks. Vitor. By the way, next website you have there. Helps me a lot. So the efficiency is a couple of percentage better than that of the belt pulley CVT...
With all this talk of transmission efficiency, we are ignoring the gear meshing / differential loss? For example, the loss on the planetary power split...
Vitor :Thus, it seams that they share the same approach. -I mean: instead of using a CVT (to widen the electric motor's capability to the whole vehicle speed...
<<I realize the Prius uses the motor for low speed. But doesn't it also use it in highway speed? Because the motor is always connected to the wheels.>> Yes,...

Tom Kasmer has just completed the website about his Hydristor CVT. http://www.hydristor.com This is a hydrostatic CVT. To see how it works, I recommend you...
Okay, I've done extensive comparision between Honda's IMA drive and Toyota's Synergy Drive. I've come to the conclusion that Toyota's Synergy Drive is slightly...
I don't see how it can achieve 95% efficiency. What makes it so much better than current hydrostatic transmission? ... click on the "Design News - Variable...
Honda's IMA is inherently more efficient in steady speed conditions such as highway comutes as it is inherently lighter and does not have the electrical losses...
the design eliminates vane tip friction. The usual friction drives a concentric nesting of endless metal belts and creates a "hydrodynamic bearing and ...

The first model was tested at Tecumseh test lab and hit 94.7% overall. So it sounds like you have made some progress in testing! What was the torque, load, and...
Honda-power is puny compared to this devices ability. See SAE paper 2004-01-0356 for details. Perhaps...however, similar type generator/motor designs are now...
But energy conversion loss and motor loss will still likely prohibit the system from achieving an efficiency of above 90%. The problem with the electric design...

right now, I am provodong those details to potential customers who are also signing my non-disclosure agreement. When my IPO is done, that information will ...
When my IPO is done, that information will become public. That is interesting...what is the date of your IPO? Glad you are making progress. I look forward to...
Ken, You missed the point. The earlier email referred to how much better the Honda system could be if a highly efficient-high powered mechanical device was ...

Thanks. I realize the system is a hydrostatic transmission. In order to achieve that kind of efficiency, the pump and the motor both need efficiency of about...
