The earthen solar cooker is a low cost and low environmental impact design by Bart Orlando for use by the poor in refugee camps and in villages of nonindustrialized nations. The design is simple; a large parabolicly shaped hole in the ground lined with reflective materials such as salvaged pieces of broken glass mirrors, reflective can lids or with funding, approximately 50 one foot diameter mirror finished aluminum food serving plates collected each day by10am and used to line the hole (earthen solar cooker). Sunlight is concentrated to the base of the hole where 10 one gallon black containers of water can be boiled per hour and used for drinking or food preparation. (A 7ft diameter hole, 5ft deep cooks 10 gal of rice/hr from 11am to 3pm on an 85f summer day in south central Oregon.) The plates are redistributed with servings of the solar cooked food. When cleaned, the reflective plates can be used as person grooming mirrors until collected the next morning for solar cooking again. As part of a food aid program to prevent stunting of malnurished children, shipments of canned vegetables in 1 gallon cans specially designed to have flat, mirror finished lids of stainless steel which can then be used as reflectors. The remaining can cylinders could be used to fashion rocket stoves or solar cooking/water pasteurizing pots once blackened over a wood fire. (see photos below)
