Infinitely Variable Transmission?
This is what I came up with and I would like to hear your opinions on it. It starts with input to a differential, one side of which is inverted and the other isn't before returning to a second reverse powered differential. The two sides are slowed using a fluid braking system which has a rotor powered by the side's drive-line, and a flow limiting valve to apply resistance. As one side slows the other accelerates. When there is no brake power on either side you have reached a powered neutral, and when the second side is braked the direction changes and accelerates.
So, will it work? How practical is it? Are you going to say it sucks, then steal my idea?
