Abstract:
The present invention relates to a parabolic solar cooker designed for efficient and sustainable cooking by harnessing solar energy. The cooker features a precisely engineered parabolic reflector with a diameter of 1.40 meters (customizable to other sizes), capable of concentrating sunlight onto a focal point to achieve high thermal intensities suitable for cooking a wide range of foods.

Technical Field:
This invention pertains to the field of renewable energy appliances, specifically solar thermal cooking devices utilizing parabolic reflectors to convert solar radiation into usable heat.

Background:
Traditional cooking methods often rely on fossil fuels or biomass, contributing to environmental pollution and deforestation. Solar cookers provide an eco-friendly alternative that reduces reliance on non-renewable energy sources and improves public health by eliminating smoke emissions.

Detailed Description:

• Reflector Geometry: The solar cooker employs a parabolic reflector with a diameter of approximately 1.40 meters, constructed from lightweight, durable materials such as anodized aluminum or reflective polymer sheets. The parabolic shape ensures that incoming solar radiation is focused precisely at the focal point to maximize heat concentration.

• Focal Point: Positioned at the parabola’s focal length, the cooking vessel or receiver is supported by an adjustable mount allowing optimal alignment with the sun’s rays throughout the day.

• Support Structure: The cooker includes a stable, adjustable frame designed to maintain the reflector’s orientation and angle, accommodating geographic latitude and seasonal sun path variations.

• Thermal Efficiency: The design achieves high thermal efficiency by minimizing reflective losses and maximizing solar radiation absorption at the focal point. This enables cooking temperatures exceeding 200°C under optimal solar conditions.

• Scalability: The parabolic cooker can be manufactured in various sizes to accommodate different cooking needs, from small portable units for individual use to larger models suitable for community kitchens or institutional applications.

• Additional Features: Optional enhancements include transparent protective covers to reduce convective heat loss, adjustable tracking mechanisms for automatic sun-following, and integration with thermal storage systems for cooking during off-peak sunlight hours.

Industrial Applicability:
This solar cooker design is highly suitable for manufacturing by companies specializing in renewable energy appliances, outdoor cooking equipment, or sustainable technology solutions. The modularity and scalability of the design make it adaptable for diverse markets and user requirements globally.
