Scientists at Linkoping University made bean roots conduct electricity and store energy. For this, the plants were watered with a solution with a conjugated ETE-S oligomer. It absorbed into fabrics and created a conductive polymer film, liu.se reports.
Bean roots could conduct electricity for at least a month with an indicator of 10 siemens per centimeter.
(Siemens is the reciprocal of an ohm for electrical conductivity. By definition, Siemens is equal to the electrical conductivity of a conductor whose resistance is 1 ohm.)
To store energy, scientists created a supercapacitor, in which the roots worked like electrodes in the process of charging and discharging. During the study, the beans grew and developed normally.
Before that, scientists conducted a similar experiment with roses. A bean-based supercapacitor stored 100 times more energy than a flower cell.
