Summary The application of an inorganic phase change material (PCM) on instrument panel for temperature control is reviewed here through numerical simulation. A constant heat flux is provided on one face of the panel, and the inhibited temperature build‐up is studied for different modes of PCM placement. The distribution of microencapsulated PCM over the surface of the panel as embedded in the paint layer reduces the temperature gradient that is unavoidable for lumped placement at one location on the panel, which also affects the average temperature. The effect of the size of microcapsules, ranging from mm to μm scale on characteristics of temperature build‐up, is reported here under two different exposure conditions of upper surface of the paint layer, that is, natural convection and fully insulated condition. The cooling characteristics of the panel in the absence of heat flux are presented.

Solar automatic fire tracker & extinguisher system is a new innovation technology and designed by our technology station (Process, Energy and Environmental Technology Station, University of Johannesburg) in combination with the characteristic of heat & fire detection apparatus. This industrial automation fire extinguisher have a platform with 90 degree of freedom and the DC motor base wheel will be passive or active, fixed or steerable according to system logic control unit to target a fire source. To get the system more effective and flexible the wheel will regulate with two characteristics: 1. Wheel spinning, 2. driving control. The whole system will operate by Solar energy source because it can be use in remote areas where it is too difficult to extend the electricity power grid connection to the fire extinguisher (solar extinguisher is not fix unit, it will always travel from one place to another place to find photon and detect flame). The most fun about the project is to watch him navigate from light source to light source trying desperately to stay alive. This character is the secondary operation when the battery status under the level of 60%.

This work is a development of an indigenous technology combined Flap-motor power generator (FMPG) and PV system that harnesses the free renewable energies in rural area to generate electricity. FMPG and solar renewable energy power technologies are affordable, clean and sustainable and can replace or supplement power generator for road traffic signal light. Combined energy systems integrate these renewable energy technologies with flap base car passing power generators, PV and batteries to provide road signal power in remote areas not connected to a utility grid. Such an isolated grid will help to supply electricity for traffic signal to avoid road accident and maximum vehicle efficiency at intersections. This power generation device will provide constant power supply while no sunlight for long days. At the same time technology will represent instance power supply for rural area traffic light electrification system without grid connection.
