It can be that simple

This blog is starting to become only about the hexayurt, however I want it to be about how low tech can save the world. It is often too easy to try to fall into the trap that some new fancy technology (cold fusion) is gonna solve all of our ailments. Maybe it will but what really gets me buzzing is not the anti mosquito laser turrets. It is the stuff that makes me think, “It can’t be that simple”. The hexayurt is one of them, using a foot of insulation in homes is another. However, I don’t think I have ever seen one as midbogglingly simple and world changing as this one.

The SODIS Method

In 2004, only forty-two percent of people in rural areas had access to clean water. Leaving contaminated water in clear plastic bottles in the sunlight for 6 hours (or 2 days if not sufficiently sunny) decontaminates the water. After the number of health, water and sanitation workshops I have attended I was surprised this has been around since 2006 and it was the first time I had heard about it.

There are a bunch of variable factors but nothing major.

Technology so simple all you need is a leaflet or a teacher, (and soap and bottles but I will assume those are in place.)

this is the kind of stuff I think will really change the world for the poorest. Coming soon, simple mobile stethoscope and how to make and carbon negative fires
