This is a short update on our project to develop an indicator for the method of Solar Water Disinfection (SODIS). Things have been busy at our side: Our partner for the development of the indicator, PotaVida (http://potavida.org) not only produced the first series of prototypes but also participated at the Washington Environmental Innovation Challenge of the University of Washington. They placed second, which is a great achievement considering the strong competition from 104 other teams.
In the next few weeks, we will start calibration measurements of the prototype, whereas the team of PotaVida already is working on an improved design of the device. The requirements are very challenging: it has to be waterproof, resistant to solar radiation and heat, lightweight and low-cost.
Based on the data of calibration and laboratory experiments, we then will produce a small series of the indicator and field test it with potential users in the second half of 2011. We are currently raising funds for these field tests and welcome any support to bring us closer to our goal: to facilitate the promotion of Solar Water Disinfection, which has the potential to benefit millions of people who currently do not have access to safe drinking water.
We also would like to point out to the “recurring donation campaign” on the Global Giving website. With this new feature, you can now donate over a certain period of time (e.g., $10 per month), rather than one amount at a time. Such recurring donations help us to improve project planning and we would like to encourage you to make use of this function for future donations.
Thank you again for your support.
