Bacteria able to generate electricity in microbial fuel cells (MFCs) are of great interest, but there are few strains capable of high power production in these systems. Here we report that the phototrophic purple nonsulfur bacterium Rhodopseudomonas palustris DX-1, isolated from an MFC, produced electricity at higher power densities (2720 +/- 60 mW/m2) than mixed cultures in the same device. Wh...

Enzyme-based biofuel cells (EBFCs) are systems that use a variety of organic compounds to produce electricity through oxido-reductase enzymes, such as oxidase or dehydrogenase as biocatalysts immobilized on electrodes. In this study, a single-chamber EBFC consisting of carbon electrodes that operating at ambient temperature in phosphate buffer, pH 7 is reported. The EBFC anode was based on gluc...

introduction nowadays, energy, water and environmental issues are the intersection of all human’s requisites. supplying energy from a wide range of clean sources is a reliable response in order to obtain all of the requisites of mankind. salinity gradient power is a clean energy source that is available everywhere and has the capacity of supplying a reasonable amount of energy suitable to be us...

Renewable energy provides 20% of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It provides almost onefifth of the electricity in world. Hydropower is produced in more than 150 countries. The main objective of this paper is modelling and analysis of the effects of the power system stabilizer (PSS) for load frequency control (LFC) system ...

BACKGROUND Much research in the field of energy harvesting has sought to develop devices capable of generating electricity during daily activities with minimum user effort. No previous study has considered the metabolic cost of carrying the harvester when determining the energetic effects it has on the user. When considering device carrying costs, no energy harvester to date has demonstrated th...

In the Ontario power system, almost all coal power plants have been recently closed. The major power generation in Ontario is currently provided by nuclear power plants (base-load generation). Additionally, wind generation typically is maximum at night, a time period when the demand is minimum. This raises the question whether energy storage systems (ESSs) should be deployed in Ontario to shift...
