Seven tips to help your invention succeed
Featured Article
Many of you learned about the distribution challenge from my colleague and Essmart's co-founder, Jackie Stenson. If you haven't watched her E4C webinar, please do so. It is a fantastic introduction to the problem of distributing the life-improving technologies that many of you are inventing at this moment. She highlights the truth that our social enterprise, Essmart, was founded on: Even though you may have created an amazing technology that is a real labor of love and technical wizardry, distributing it to the people you made it for will be your biggest challenge.

Pit Latrine Emptying

We are developing a mechanized technology to empty pit latrines. Currently, they are often emptied by hand, which is unsanitary, or by vacuum tankers, which cannot physically access many latrines. One issue we have run into in field testing is the presence of household trash in pits (usually plastic bags and cloth). We are looking for ways to remove the trash BEFORE emptying the pit, or to grind it down to smaller sizes that can be more easily removed (~2 inches long). This would lead us to a two step process: 1) Remove/grind trash 2) Remove sludge We have had success with the second step, but the trash poses an issue. We are using a 27 HP gasoline-powered engine with a hydraulic motor for the sludge removal step, so it is available for the trash removal/grinding step as well. The question we really have is... what can grind up trash in sludge, or what can remove it from the sludge quickly and hygienically (some sort of "fishing tool" or maybe a rotating tool?)

Handmade windcatcher for a girls' hostel in Malawi

We are designing and building a hostel for girls who are going at the Liwonde Secondary School. This building will provide a safe place for those girls, who have to wlk long distances to study. We want to maximise the amount of fresh air coming inside the rooms, and this is why we are looking for an open source way of designing a windcatcher (http://www.monodraught.com/products/natural-ventilation/15/windcatcher-x-air/products/natural-ventilation/15/windcatcher-x-air/?info=70). We would like this windcatcher to be easy to reproduce, in order that the community can easily produce others. It is possible to get more information about this project on our website:http://gcius.ca/index.php/projet-2014-liwonde-malawi/21-projets/projet-2014-malawi/58-projet-2014-liwonde-malawi-english.
