Talks by John Barrie
01 Solar Power Saves Lives
In many parts of the world, families still rely on candles and kerosene for light. This talk explores how simple solar technologies are improving health, increasing household income, and helping children stay in school.
02 Designing Technology for a Billion People
Technology is often designed for wealthy markets and stable infrastructure. This talk explores how engineers and designers can create practical technologies that work for the one billion people who still live without electricity.
03 What Works in Humanitarian Technology
Technology is often designed for wealthy markets and stable infrastructure. This talk explores how engineers and designers can create practical technologies that work for the one billion people who still live without electricity.
John Barrie speaks at conferences, universities, and events focused on solar power, sustainable technology, engineering, and global development.
