Hi, and thank you both for your input. I am in the process of getting the last bits and pieces together for my 88 Nissan, and after I am able to drive it, the idea was to try different things to improve range. Because of some long 10% grades going into the next town, I thought regen might help. Will keep researching and posting. BTW wind tubines are also something I would like to try for a small charging station. Thanks again, Take care, Watt
