A brand new design for a photo voltaic cooking system might assist rural communities put together meals extra sustainably, experiences a brand new research. The supplies used on this system must be simply accessible for individuals in locations the place there are few choices in addition to burning wooden or coal.
Engineers in Nigeria have developed an improved photo voltaic cooking system that’s designed to interchange cooking over fires made with coal, wooden, or different supplies, in line with the research which appeared in Frontiers in Vitality Analysis. There are nonetheless many components of the world the place individuals cook dinner instantly over such fires, which is damaging for the setting in addition to the local people’s well being. This new method combines two standard photo voltaic oven designs and goals to offer a cleaner and more healthy various.
“Cooking by the burning of firewood and different non-environmental and non-eco-friendly fuels remains to be predominant in most growing nations, particularly among the many individuals residing in rural areas and a few city cities,” stated lead creator Dr Clement A. Komolafe, of Landmark College.
“To be able to discourage using hazardous fuels for cooking, we considered combining the photo voltaic field and parabolic dish sorts to supply one novel photo voltaic cooking system utilizing regionally sourced supplies.”
A mixture of two designs
There are two precept preparations for standard photo voltaic cookers. The primary is a field (typically fabricated from glass or a clear materials), which traps warmth from the solar’s rays. The second is a parabolic or spherical construction that displays and focuses daylight to accentuate the warmth.
This newest cooker combines each approaches to seize much more warmth. The preliminary checks confirmed that the cooker obtained heating energy (wattage) of as much as 58.2W, which was sufficient to boil water, in addition to cook dinner rice and plantains. This efficiency compares effectively with present traits in photo voltaic cooking applied sciences.
Design options additionally embody making it simple for one particular person to function and easy to assemble. As well as, no particular coaching could be wanted to make use of the gadget.
Domestically sourced components and supplies
The group seemingly used simply accessible supplies resembling aluminum sheet, iron, metal pipes, plywood, and reflective glass to construct the gadget. The group additionally in contrast two warmth storage supplies that may be simple to entry: black coated gravel (granite) and used engine oil. A monitoring gadget offered the electronics wanted to measure the temperature and humidity for the research.
“The subsequent steps embody design modifications to additional scale back the speed of warmth loss by means of the wall of the cooking field for higher effectivity,” stated Komolafe. “For fast redistribution of this new gadget design to rural communities, we’re inviting People, company organizations, and authorities parastatals to sponsor or accomplice within the challenge.”
