All it really does is allow both wheels to spin at the same speed. Which happens to feel like its "transferring power from the wheels that slip to the wheels that grip."
An open dif. is like having one wheel drive in a two wheel drive car. An LSD is like having two wheel drive in a two wheel drive car.
There is a lot of technicla junk about it, but that the basic..."How Stuff Works" will probably tell you better than I did.
The solution to these problems(open differential) is the limited slip differential (LSD), sometimes called positraction. Limited slip differentials use various mechanisms to allow normal differential action when going around turns. When a wheel slips, they allow more torque to be transferred to the non-slipping wheel.
