I figured out how to make one and made a smaller model, this article made me stop and think how lucky I am, and how great it is that people are trying and succeeding to help!

I think that they need this all over the world. Especially on densely populated areas like China, India, and many other rural countries. That way, we can reduce air pollution and less people would die.

This is the coolest thing ever! Never heard of the band though! :)
