Why is biodiesel neglected? So many people don’t have any concept of it! Why don’t you do an information blitz on this subject?

I'm not so sure biodiesel is all that neglected. If I did an information blitz on it, I'd remind its boosters that biodiesel is no magic elixir for a clean-energy, safe-climate future. Biodiesel could be a small part of our energy portfolio, if we were willing to intercept more oil and grease and divert it to fuel tanks before it reached our fast-food-crammed guts. And it’s certainly worthwhile to retrieve used kitchen oil and grease to run your car, as long as you don’t think you’re saving the world by gorging on Big Macs and avalanches of french fries to supply the raw, or, um, cooked material.
