Affecting One Billion People
Here is an idea that could potentially affect 1 billon people; a sustainable fridge. Just heat it up on a cooking fire for 30 minutes, let it cool for 1 hour, finally place it inside the container to cool. No electricity required. It will cool a 15 litter vessel down to near freezing for 24 hours. Great for storing vacines, food, etc. Cost $25 in high volumes and $40 in low volumes.
