Moisture Power: A New Type of Clean Energy

 

Abstract

Harvesting energy from clean and renewable sources has boomed the development of diverse electrical generators to satisfy the growing demand of electricity in our daily life. Moisture enabled electric generator (MEG) is proposed as a means to produce electric power from air by absorbing gaseous or vaporous water molecules, which are ubiquitous in the atmosphere. In this regard, we designed and developed a series of graphene based MEGs with a heterogeneous structure and interface mediation between electrodes/materials with Schottky junctions. Benefiting from the functional groups-reconfiguration and inner protons asymmetrical distribution, the asymmetric porous graphene oxide membrane can proactively generate a sustained electrical voltage approaching 1.5 V. High voltage of up to 1000 V can be easily reached by simply scaling up the number of MEG units in series, enough to drive many commercial electronic devices such as liquid crystal displays (LCD) and light-emitting diodes (LED). This work provides insight for the design and development of MEGs that may promote the efficient conversion of potential energy in the environmental atmosphere to electricity for practical applications.
