the dvd is poor and the system they tell you to build is all 12volt dc.the socall wind generater is being made out of all old car alternator. that look like a old bird with fan blades.so it will only produce 12volt and not much of that.unless you have about 5 acers of land you are wasting you money and there is no way to get in touch with them.
