Peter Saunders must be one of the world's leading examples of entrepreneurship.

He never stops thinking and he never stops helping.

This talk tells the story of how he went from buying a small honey ice cream business at the age of 25, to securing millions of dollars from the Bill & Melinda Gates Foundation in his quest to solve the cold chain issues around immunisations in countries where there is little or no power. Oh, and in the middle of it all he set up what became the top training school in Europe for helicopter pilots.

The world needs more Peters.
