Adaptive Alcohol Cooking Stove
The concept of the alcohol stove was birthed from the idea of burning pure organic compounds. The growing popularity of the can-alcohol stove has made the idea attractive. Most people today use it when camping, to heat food, and to cook as well. The alcoholic fuel must have a substantial alcohol percentage of about 70% and above before it can be used as fuel. This property makes rubbing alcohol (methylated spirit) suitable for the stove.

Reducing Coconut Husk Pollution Using Cellulose- Degrading Bacteria to Make Self-Illuminating Ceiling Tiles
The study of Engineering is always exciting! Did you ever know that even Biology can be engineered? Well, it can, and is done presently. The fusion of engineering and biology is a breakthrough as seen by many scientists and is termed Synthetic Biology. Synthetic Biology, according to the National Human Genome Research Institute, is a field of science that involves redesigning organisms for useful purposes by engineering them to have new abilities. Amazing, right?

Determining The Best Load Scheduling Algorithm For A Home With Electricity Supply From Grid And Solar
Improving energy efficiency is becoming increasingly critical to reduce energy consumption and to solve the environmental crisis. The following paper describes a mixed-integer linear programming optimization algorithm to minimize the peak demand at the micro-grid level and to reduce the cost function in a smart home environment. The optimization methods take into account the time- varying electricity price and the varying energy demand peaks to determine the most suitable time to use home appliances. The algorithms are further used to compare the energy cost reduction results with and without the use of renewable resources and more precisely photovoltaic modules. Also, the sizing of a photovoltaic system is implemented to achieve further efficient energy optimization and appliance scheduling. Finally, a cost-benefit analysis is performed on all the scheduling algorithms to determine which is the most cost-effective.

Maximizing energy harnessing in solar ovens to use environmentally friendly energy: Material and angle of inclination
This paper reports on how a solar oven can be home-made, using cheap and readily available materials in the quench of using clean and renewable energy as an alternative to harmful fossil fuels for baking. We compared the heating effect of three readily available aluminium composites. We also analyzed the compromise angle of inclination of the reflectors for maximum possible energy harnessing to increase the efficiency of the solar oven. The analysis is statistically based and was examined using a 0.05 significance level.
