Article on Determining Price Points for Boko Fan/Light Console

Malaria Journal, one of the leading academic journals for Malaria research, has published a third article relating to our Boko Pilot study in Ghana. The research for this article was conducted by GWHN, in partnership with Tulane Univeristy, the Univeristy of Switzerland and the Noguchi Memorial Insitute for Medical Research.

Determining Price for Boko Fan/Light Consoles

While the two previous Malaria Journal articles published focused on whether having a fan/light console inside a mosquito net will increase net use (it does), this research was conducted to obtain prelimary information on what prices our study participants would be willing to pay for the fan/light consoles. This “Willingness to Pay (WTP)” Study provides helpful information for determining price thresholds and whether a viable business model can be developed to sell the fan/light consoles in impoverished rural areas where malaria is endemic.

The results of this study show that the mean WTP was approximately 55 Cedis (~13 USD). We also demonstrated demand suggesting that at a price that would support full manufacturing cost recovery a majority of households in the area would be willing to purchase at least one such system.

Below is a link to our article “Willingness to pay for small solar powered bed net fans: results of a Becker–DeGroot–Marschak auction in Ghana”:

Because of these continued positive results that show our idea is both effective and affordable, our next step is to develop a business model to sell and distribute our Boko Solar Systems, household solar systems that bring electricity and light to homes and which include the fan/light consoles to be used with mosquito nets that help reduce Malaria and save lives.

Bɔkɔɔ Study results published in Malaria Journal

The results of our Bɔkɔɔ Pilot Study conducted in Apese and Amanfrom Ghana have been published in two articles in Malaria Journal that can be found in the December 2016 and January 2017 issues of this prestigious publication. While both articles are encouraging and show promise for the Bɔkɔɔ fan/light console as a malaria prevention tool, the conclusions are also that more studies are needed to further validate our findings.

The latest article found in the January issue is a quantitative analysis and shows a positive correlation between bed net use and the use of the Bɔkɔɔ fan/light console. The article can be found here:

The first article found in the December issue is a qualitative analysis and shows that there is both a demand and desire for the Bɔkɔɔ fan/light console. The article can be found here:

In combination, these studies are encouraging and GWHN hopes to begin a scale-up study in 2017 in partnership with our research partners: Tulane University, The University of Switzerland- Basel and the Noguchi Memorial Institute of Medical Research.









Bɔkɔ Pilot Study Completed- Encouraging Results!

Villagers & researchers- Apese, Ghana 

The Bɔkɔ Pilot Study was completed in the villages of Apese and Amanfrom, Ghana in January (2016). We are very grateful for to all the participants in this study and to the local people who helped us with solar installations and keeping the project on track. Also special thanks to our team of data collectors from the Noguchi Memorial Institution of Medical Research, our project partners in Ghana.

Since the completion of the study, findings have since been analyzed by our project team lead by researchers from Swiss Tropical Public Health of the University of Switzerland- Basel and Tulane University’s  School of Public Health. Several manuscripts pertaining to our findings (both quantitative and qualitative) were created and submitted this summer for publication.

The findings of our pilot study were very encouraging showing high demand for our solar-powered fan/light consoles that go inside mosquito nets to keep people comfortable at night. We also achieved 99% bed net use rates with our Bɔkɔ fan in place, much higher than the national average in Ghana of around 50% use rates.  However, we have also concluded that a larger study is needed to further validate our results.  We hope to begin a scale-up project study in various parts of Ghana, and perhaps in an Asian country as well, in order to confirm our preliminary findings and expand our research and knowledge with regards to using the Bɔkɔ fan/light as an effective malaria prevention tool.

GWHN Supporters Come In All Sizes

We are always happy when the work that we do at GWHN has a positive effect on someone’s life, especially our kids. After all, they are our future and will someday lead the fight to bring universal use of green technologies and help eradicate deadly diseases such as Malaria.

Jackson  Boyd is one such kid. Jackson recently completed a science project and gave a presentation on solar power. He met with GWHN Executive Director, Peter Nardini, and obtained some solar cells and information on how to build solar panel for his experiments.

Jackson has a unique perspective on electricity as he grew up with solar power and all his neighbors have solar power in their off-grid community near Taos, New Mexico. Check out Jackson’s presentation here. We think that Jackson has a bright future. (pun intended!)



Boko Project – Moving on to Phase II

The Boko Project research team recently returned from Ghana where they collected  data for the first 5 months of our pilot study.

The good news is that up to the midpoint of our 10 month study, the fans are being used by over 95% of those who have received them. Furthermore, the use of the fans are resulting in greater use of the mosquito bed nets, which are a proven and effective malaria prevention tool.

The midpoint work included installing small solar systems in 30 new homes. Over the

course of several months, GWHN solar expert, Bill Miller helped trained four community members to conduct the solar installations and they are now able to do these installations unsupervised.

Boko Project partner, the Noguchi Memorial Institute of Medical Research (NMIMR), will continue to collect data on the use of the fans and bed nets up until January. Researchers from the Boko Project will return in to Ghana in January to complete the study.

At the end of the study all community households will receive a solar system and a water filter for helping us study the effect of the Boko fans on bed net use. We will be auctioning off the fan/light consoles to determine their value for members of our study community. This information will help us determine next steps in terms of console design and barriers to use.
