Roaches may be your cellphone charging alternative

by Gareth Mankoo

The hamster may have served his time on the wheel because now we have spotted some potential in cockroaches. And what good are they elsewhere anyway? Why not get them to light out homes and charge our gizmos, for all those years of tormenting frights they have bestowed upon us? When a cockroach was rigged with electrodes it managed “a maximum power density reached nearly 100 microwatts per square centimeter at 0.2 volts. Maximum current density was about 450 microamps per square centimeter.” And the credit for this goes to the chemical reaction in the insects’ body.

The five-year study seems to have paid off satisfactorily. We are hoping it hits top gear.
