With the ever-increasing demand for energy, we have to focus our attention on greener alternatives. The main problems with non-conventional energy sources are that they need storage. Flywheel batteries seem to solve this problem to a great extend. Flywheel energy storage systems are non-polluting; need no replacement and little maintenance. The basic working of flywheel batteries and their applications are discussed in brief. Flywheel batteries stores energy as rotational kinetic energy of the flywheel and this energy can be retrieved either th ....etc

Nuclear Batteries-Daintiest Dynamos

Micro electro mechanical systems (MEMS) comprise a rapidly expanding research field with potential applications varying from sensors in air bags, wrist-warn GPS receivers, and matchbox size digital cameras to more recent optical applications. Depending on the application, these devices often require an on board power source for remote operation, especially in cases requiring for an extended period of time. In the quest to boost micro scale power generation several groups have turn their efforts to well kno ....etc

Bacteria powered batteries use the chemical energy generated by bacteria, and convert it into electrical energy using a relatively simple mechanism. Like most batteries, a bacteria powered battery has an anode (the negative end) and a cathode (the positive end). In addition to the anode and cathode, a bacteria powered battery also has a membrane capable of filtering electrons (anions) and protons (cations) produced during the chemical breakdown of substances by bacteria.

Abstract

A Vanadium-Vanadium Redox battery can improve Photovoltaic system performance, reliability and robustness by increasing the energy conversion efficiency of the battery to 87%, by making the battery life, efficiency and ongoing energy capacity independent of state of charge and load profiles and by reducing maintenance requirements. High battery efficiency reduces the required PV while a battery life insensitive to battery usage relaxes system constraints. These advantages are utilised in a demonstration PV system in Thailand that w ....etc
