Abstract
The invention discloses a tubular hydro-voltaic device configured to generate voltage and current. The device includes a tubular structure containing activated porous carbon of predetermined thickness and length. The tubular structure is placed in a reservoir of fluid whereby the contact between the tubular structure and fluid produces a capillary action of the fluid into the tubular structure forming an electric double layer at carbon particle-water interfaces of the activated porous carbon material leading to voltage and current generation. The voltage and current generated by the tubular hydro-voltaic device are a function of the thickness of the tubular structure, the length of the tubular structure, or a combination thereof. The device has potential to provide power at remote locations, as a device of size 50 mm length×10 mm diameter×1.5 mm thickness is capable of generating mA level currents at 0.85 V or more.
