<p>@Dean J What do you mean retooled it? As I see it now, it looks like many students will go for the water purifying/solar panel ones. I had a really cool and high-brow idea for it, but that got shot down when I reread it, because it was something that there might not be the technology for for a few decades, and I realized that you all were probably looking for something small and able to be done yourself. But it was unique and interesting. </p>
