I am amazed by your project, you are a genius, its good news for the rest of southern africa, I am more interested in how to go about fnding you and look for ways to bring that kind of service to the Namibians in rural areas as well.

Congratulations

Emily, Grant and all, nice going!… or nice doing! One concern I have about the design is how long will these Hippos last? How long before a hole is worn through the side from the abrasion from rolling them on rocky soil?

A solution I thought of would be to add a couple of giant rubber bands around them to create a wear surface — essentially a small tire to absorb the majority of the abrasion. An idea for your consideration. ~Pete

Congratulations Emily – this is so exciting and it would seem the Project H initiatives are really kicking off. This is such a great concept and I can’t wait to see the evolution of Project H over the next few years.

Amazing how this sort of enabling technology is completely available right now, all it takes is for someone to actually DO it. To put in the time and get it out there. sweet work

When I first saw this design, the idea was to persuade manufacturers to switch to this kind of barrel, which could then be reused to carry water. Is that still in the works, or has that delivery model been dropped?

I’m sure that the barrel is easier to roll with the metal bar. The prototype used a rope through the center.
