I really enjoy his videos, however there was one where he created a packed bed filter and suggested it made the water safe. It certainly makes the water look cleaner but that is a long way from being safe to drink.
It made me think twice about his credentials.
- redis_mlc 6y agoIf you expose water to sunlight UV, it will sterilize.
- VBprogrammer 6y agoAbsolutely, if the sun is able to penetrate (the container is UV transparent i.e. plastic bottles) and there aren't large clumps in the water which protect the pathogens from exposure. Which would make a packed bed filter a reasonable pre-filter before bottling and leaving in the sun for a number of hours. However, that wasn't what he said in the video, which was that the water hadn't been tested but was probably safe to drink.
