Product description Brand name and product description

The Hot Spot Concentrating Dish is a 114 cm  (45 in) diameter of highly-reflective aluminium plate that catches sun’s radiant energy and concentrates it to a 10 cm (4 in) to 15 cm (6 in) diameter spot of highly concentrated energy. This energy is easily directed onto any cooking surface. It boils 1,36 litres (48 oz) of water in 15 minutes at 900 W/m2 sunlight intensity and up to 538 ºC (1000 ºF) temperatures are easily achievable on a sunny day.

The reflective film is deformed by applying a vacuum with a simple hand pump to the inside of the dish to achieve a concave shape. Slight adjustments of the dish position are required every 5 minutes so as to follow the sun’s position. The food needs to be elevated, and sunglasses are required when using the dish.

The Hot Spot Concentrating Dish is designed and manufactured by A Better Focus Company which is located in Massillon, Ohio, USA.
