Bio-Beetle took something that was on the tip of everyone's tongue, and ran with it. Actually, they ran cars with it. It's Biodiesel, and Bio-Beetle is the first all-BD rental car company. Next time you're vacationing in Maui or Oahu Hawaii, take a zip around the islands in a snappy little VW running on fuel made from used cooking oil. There have been some worries lately about the viability of Biodiesel in large scale production, so it's refreshing to see a local solution like this. And the bugs are cute.
