A team from Harvard is developing a dirt-charging phone system that will allow greater access to cell phones. With most people glued to their cellular screens almost 24/7, it seems unfathomable that anyone would not have one; but developing nations face many problems that are unfamiliar to North Americans, including not having a mobile device. Although this may seem like an insignificant issue compared to high death rates or low birth rates, the use of a cell phone is actually linked to crucial things like access to health care.
For developing nations, the use of “phones allow people living in remote areas to contact health care practitioners, or to use health care apps.” Due to the poor electrical system in these countries, it is difficult to keep these phones alive and charged. Led by Dr. Aviva Presser Aiden, the team from Harvard is developing a dirt-charging phone system “that gets its power from microbes in the soil.”
The dirt-charging phone system will be highly beneficial in providing greater health care in these developing nations.
