Working from the idea that more people will fill up with biodiesel if they knew where they could get it, NearBio offers a free service delivering a database of more than 1,000 biodiesel sellers to mobile phones via WAP (wireless access protocol) or text messaging. Just punch in your city and state, or zip code, or GPS coordinates and NearBio gives you distance, directions, address, phone number, blends and other facility details for the five closest stations.
