Global Buckets?

Hi folks! Just wondering if anyone has ever heard of these Global Buckets? Seems like a great idea for the busy, and hardworking. Hope its ok to post a link. The videos on the side are great to watch! Thanks!

Darn it I forgot the link! Here http://www.globalbuckets.org/

Looks good and i am sure it works fine, one question. What medium is used to wick the water up? A strip of cotton or something similar?

looks kinda like a modified hempy bucket
