Engineers are always on the hunt for more efficient ways to power the humble double-A battery. So far, industry geniuses have tried unusual mediums such as air and even spit. Yet the search is far from over–as electronics innovator Juan Pablo Esquivel is testing a paper battery.
“We develop small, nontoxic, inexpensive fuel cells and batteries that don’t need to be recycled and could be thrown away with no ecological impact,” he explains.
The petite power cell will charge disposable devices and microelectronics. And no–we’re not talking Hot Wheels. Esquivel aims to make pregnancy, glucose, and and disease tests cheaper and more accessible.
“Esquivel is like Cristiano Ronaldo, and, like Ronaldo, he’s playing for an excellent team. That’s why he gets results,” jokes Antonio Martínez, a professor at the Polytechnic University of Madrid.
With single-use devices hitting the bins before they lose charge, landfills could use a little less lithium.
