Our local PBS station hosted a
"Green Expo". My boss sent me to check it out. All in all, it wasn't too impessive, but there was a local company, "The Battery Post" that refurbishes 12 volt automotive batteries. They pour a "proprietary chemical" in them, put them on a pulsing charger to desulfinate the plates, and sell them for $30 a piece. They don't have a web site, but their phone no. is (574) 288-5332, email is
