3000th Post! And Gratzel Cells…

Wow.... this is the 3000th post that I've made to my blog since it's inception. Huzzah.

I really need to get a hobby.

In any case, Bill Meara over at the Soldersmoke blog mentioned this video about constructing solar cells from donuts and tea.

It sounds like a joke, but it's not. It turns out that powdered donuts aren't just white because they have powdered sugar on them, but because they also contain titanium dioxide. Who knew? You can read about them on Wikipedia.
