While working for Good Good Design I developed and incorporate a set of icons for the TEL (Technology Exchange Lab) website.

TEL is a nonprofit organization dedicated to bringing communities out of poverty by driving the adoption of innovative, cost-effective and sustainable solutions. They host a crowd-sourced database of innovations in order to connect practical solutions to the people who need them.

These icons were created to be a simple representation of the different kinds of practical solutions TEL represents: Water & Sanitation, Agriculture & Tools, Energy & Cooking, Education & Connectivity, Housing & Transport and Health & Medical Care. https://www.techxlab.org/project-accelerator/
