Design of a Matched IR Emitter for a Portable propane fired TPV Power System
ABSTRACT: The design of an IR emitter is described for use with a small portable cylindrical ThermoPhotoVoltaic (TPV) generator. The IR emitter consists of a cylindrical array of 1 to 2 mm diameter ceramic rods. The spacing between these rods is chosen such that slits are formed between the rods with a slit width equal to about 1/10* of the rod diameter. Computational Fluid Dynamic (CFD) modeling ...

Tips on Cleaning Your Solar Lights
Solar lights are not a common part of life or lighting in many households but they are gaining a bit of ground. Most of them are used outdoors and this means that they will definitely get dirty after a while. These lights require regular maintenance but the fact that these lights are placed outside means that you will probably check on them less often. You will find no moving parts in a solar ...

Swollen LiFePO4 Batteries? How To Prevent?
Swollen LiFePO4 batteries are the result of too much current inside a cell of the battery, which causes a build-up of heat and gas. This can be caused by overcharging, deep discharge, overheating to battery or manufacturer defects, or environmental reasons. In this article, we discuss why that happens and how you can prevent that. LiFePO4 battery swelling is one of the important physical ...
