There's been a lot of stuff lately that I've wanted to talk about, but I've been caught up in other things. A few quickies:

- Potential new biofuel, although Kumar warns: beware of fancy press releases.

- Our grease collection program seems to indicate that people are eating out less, or that restaurants are stretching their grease longer. Either way, it jives with the idea of an economic recession.

- The ever-increasing price of petroleum diesel poses an interesting question for Yokayo: if the "right" price for our fuel is below that of diesel, then how do we protect the supply for the customers that we've already invested time and energy in? In other words, how do we make sure that new, largely uninformed opportunists don't swoop in and buy it all up? One theory is that our price should never be below that of petroleum diesel, but that's a tough one to swallow. We think about this a lot these days.

- Finally, a question for you: Petrosun- greenwashing corporate scam artist, or leader of the algae pack? I would lean toward the former, but that might just be because I'm jaded.
