The Kyoto Box is a solar cooker constructed from polypropylene with an acrylic plastic cover. The oven traps the sun's rays, creating enough heat to boil water or cook food.
Two nested cardboard or polypropylene boxes form the oven structure. Temperatures inside the box can quickly reach 80 degrees Celsius (176 degrees Fahrenheit) [1] on a sunny day. Temperatures could reach a maximum of 165 degrees Celsius. [2] Bohmer claimed that the oven was capable of boiling 10 liters of water in two to three hours. [3]
Solar cookers are being used by hundreds of thousands of people throughout the world. Solar cookers can also pasteurize or sterilize water to provide safe drinking water without using or collecting firewood. Kyoto Box is based on the original "Hot box" solar cooker, invented by De Sasseur in 1767.[ citation needed ]
After the award of the Financial Times Climate Change Challenge 2009 the design of the Kyoto Box was modified from the original cardboard to polypropylene, boosting the cooking performance. A further innovation was the use of a white reflector instead of one covered with aluminum foil or Mylar[ citation needed ]
The Norwegian inventor, Jon Bohmer, made the first model of the Kyoto Box with his daughters then aged 10 and 5 years old. It later won the FT Climate Change Challenge award, placing first in the competition. [4] [5]
The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit as the unit. Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride. The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F.
Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy, and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.
Pressure cooking is the process of cooking food under high pressure steam and water or a water-based cooking liquid, in a sealed vessel known as a pressure cooker. High pressure limits boiling, and creates higher cooking temperatures which cook food far more quickly.
Outdoor cooking is the preparation of food in the outdoors. A significant body of techniques and specialized equipment exists for it, traditionally associated with nomadic cultures such as the Berbers of North Africa, the Arab Bedouins, the Plains Indians, pioneers in North America, and indigenous tribes in South America. These methods have been refined in modern times for use during recreational outdoors pursuits, by campers and backpackers.
A rice cooker or rice steamer is an automated kitchen appliance designed to boil or steam rice. It consists of a heat source, a cooking bowl, and a thermostat. The thermostat measures the temperature of the cooking bowl and controls the heat. Complex, high-tech rice cookers may have more sensors and other components, and may be multipurpose.
An oven is a tool which is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. Because they are used for a variety of purposes, there are many different types of ovens. These types differ depending on their intended purpose and based upon how they generate heat.
A slow cooker, also known as a crock-pot, is a countertop electrical cooking appliance used to simmer at a lower temperature than other cooking methods, such as baking, boiling, and frying. This facilitates unattended cooking for many hours of dishes that would otherwise be boiled: pot roast, soups, stews and other dishes.
The gas mark is a temperature scale used on gas ovens and cookers in the United Kingdom, Ireland and some Commonwealth of Nations countries.
A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, and advanced, large-scale solar cookers can cook for hundreds of people. Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs and air pollution, and to help slow down deforestation and desertification.
Thermosiphon is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces. Thermosiphoning also occurs across air temperature gradients such as those utilized in a wood fire chimney or solar chimney.
Sikhye is a traditional sweet Korean rice beverage, usually served as a dessert. In addition to its liquid ingredients, Sikhye contains grains of cooked rice and in some cases pine nuts. It is similar to the Chinese jiuniang and Japanese amazake.
Solar Cookers International (SCI) is a 501(c)(3) nonprofit, non-governmental organization that works to improve human and environmental health by supporting the expansion of effective carbon-free solar cooking in world regions of greatest need. SCI leads through advocacy, research, and strengthening the capacity of the global solar cooking movement. SCI has consultative status with the United Nations Economic and Social Council (ECOSOC) and was founded in 1987.
Cooker may refer to several types of cooking appliances and devices used for cooking foods.
The degree Celsius is the unit of temperature on the Celsius scale, one of 2 temperature scales used in the International System of Units (SI), alongside the Kelvin scale. The degree Celsius can refer to a specific temperature on the Celsius scale or a unit to indicate a difference or range between two temperatures. It is named after the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale in 1742. Before being renamed in 1948 to honour Anders Celsius, the unit was called centigrade, from the Latin centum, which means 100, and gradus, which means steps. Most major countries use this scale; the other major scale, Fahrenheit, is still used in the United States, some island territories, and Liberia. The Kelvin scale is of use in the sciences, with 0 K (−273.15 °C) representing absolute zero.
The kelvin, symbol K, is the primary unit of temperature in the International System of Units (SI), used alongside its prefixed forms and the degree Celsius. It is named after the Belfast-born and University of Glasgow based engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907). The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its null (zero) point.
The Groasis Waterboxx is a device designed to help in growing trees in dry areas. It was invented and developed by Dutch former flower exporter Pieter Hoff, and won the Popular Science Green Tech Best of What’s New Innovation of the year award for 2010. The word "Groasis" is a neologism formed as a portmanteau of the words "grow" and "oasis".
Wonderbag is a stand-alone, non-electric insulated bag designed to reduce the amount of fuel required in the cooking of food in developing countries. Instead of being placed on a stove for the duration of the cooking period, food is instead heated to a hot enough temperature then transferred to the Wonderbag, which uses the principle of thermal insulation to continue cooking, and keeps food warm without needing additional fire or heat. Working on the principle of thermal cooking, the Wonderbag is estimated to save up to 30% of the total fuel costs associated with cooking with Kerosene ("paraffin") alone. In developing countries there are numerous advantages for the product, as it immediately helps ease deforestation of natural reserves, and it frees up those who would spend their time gathering the extra wood for fire fuel.
Community Cooker Foundation is an initiative by Planning Systems Services Ltd. in Nairobi, Kenya, established in 2010, with the goal of using the Community Cooker, a simple stove designed to turn rubbish into safe, clean and cheap energy, to transform Nairobi's largest slum, Kibera.
A multicooker is an electric kitchen appliance for automated cooking using a timer. A typical multicooker is able to boil, simmer, bake, fry, deep fry, grill roast, stew, steam and brown food.
