The Simple Way to Purify Water
- Take an empty transparent bottle
- Fill it with water
- Leave it out in the sun for 6 hours
- Drink the water

Does anyone else feel that we’ve been wasting a lot of resources building solar panel powered water purification plants? All this time we could have harnessed the sun’s rays directly.
