Hello, I am currently working on a project which involves using a turbine to charge some rechargable batteries. I am currently in the beginning stages of the research and have some questions right off the bat. 1. Does anybody know what is needed to go from a turbine output to the batteries. Can I assume that the output from a turbine moving at a constant angular velocity will be a constant DC current? Is a voltage regulator required, or diode and capacitor combination in order to maintain a constant voltage/current for constant and/or nonconstant angular velocities? If anyone knows of a website that does a good job of teaching the fundamentals of turbines that would be great. 2. Does anybody know of any sites where I can get some good information about some of the turbines currently on the market? Would it be better to buy a prepackaged all in one deal, if so does anyone know where I might find one? 3. Somewhat unrelated, does anyone have any good electrical engineering fundamentals websites? I find that most sites simply give a schematic and don't really address the theory. I appreciate any information.
