The Water Channel is offering US$500 for the best idea for an alternative to the jerrycan. The ergonomics of jerrycans, which up to 80 million women in Africa have to use to carry water daily, can result in a high prevalence of spinal and back pain. There are a few alternatives like the water back pack and Hippo Roller, but the Water Channel is looking for fresh ideas: either to promote existing improved devices, or breakthrough designs as alternative options. The deadline is Dec. 15, 2012. Send idea and proposal entries to email@example.com.
