Comments Off on Wilson Solar Grill Stores the Sun’s Energy for Nighttime Fuel-Free Grilling

Many of us will be firing up our grills this weekend for some well-deserved barbecue time. After all, barbecuing is one of America’s greatest pastimes, but it certainly isn’t one of our most environmentally friendly. Whether you prefer charcoal, wood chips or propane, grilling releases emissions and contributes to poor air quality. Up until now, solar powered grilling has required, as you might expect, the sun, which means traditional fuel-fired grills are required after sunset. But new solar technology developed by MIT professor David Wilson could bring a nighttime solar-powered grill to the market very soon; an invention also of great benefit to those in developing nations who rely on wood to cook all their food. Wilson’s technology harnesses the sun and stores latent heat to allow cooking times for up to an amazing twenty five hours at temperatures above 450 degrees Fahrenheit . The technology uses a Fresnel lens to harness the sun’s energy to melt down a container of Lithium Nitrate. The Lithium Nitrate acts as a battery storing thermal energy for 25 hours at a time. The heat is then released as convection for outdoor cooking. “There are a lot of solar cookers out there,” says Wilson, “but surprisingly not many using latent-heat storage as an attribute to cook the food.” Wilson developed the idea after spending time in Nigeria, where wood is used for cooking, which causes a number of problems. Not only is cooking with firewood leading to respiratory illnesses , but is also increasing the rate of deforestation and women are being raped while searching for wood. A group of MIT students are working with the technology to develop a prototype solar grill. Derek Ham, Eric Uva, and Theodora Vardouli are conducting a study through their multi-disciplinary course “iTeams,” short for “Innovation Teams”, to determine the interest in such a concept and then hopefully launch a business to manufacture and distribute these grills. The goal is to develop a business model for distributing solar grills to developing nations as well as a grill for the American market. The American version is expected to be a hybrid propane/solar model that will allow for flame cooking as well as through thermal convection. If all goes well, in a couple years we just be giving solar grills as presents on Father’s Day and enjoying sun-kissed instead of char-broiled even after the sun goes down. + Solar Grill on Barbecue Lovers Via Treehugger Images ©Derek Ham

Comments Off on Fukusada + Pereira’s Faro Eco-Fireplace Is Designed for Impromptu Gatherings

Faro is a portable fireplace designed for bringing people together in a era saturated by technology. Made with clay, an iron frame and an EcoSmart ethanol burner, the piece was designed by Japanese Ryosuke Fukusada and Portuguese Rui Pereira . Concerned that a modern, high-tech world can promote anti-social behavior, Fukusada and Pereira wanted to create an object for warmth , relaxation and gathering. Safe for both indoor and outdoor use, Faro can also be placed outside and use as a wood burner. We have a hunch that Faro will be bringing people together when it premieres at this year’s Milan Design Week ! + Ryosuke Fukusada + Rui Pereira Via Spoon & Tamago Photos by Fukusada and Rui Pereira Permalink | Add to del.icio.us | digg Post tags: “green furniture” , clay , eco smart , ethanol burner , Faro , green events , green materials , green products , Milan Design Week 2013 , Rui Pereira , ryosuke fukusada , social design , stove , woodburner

Comments Off on 10 eco friendly stoves designed to reduce environmental pollution

C.S. Akhila: Oorja cooking stove Oorja cooking stove with fuel pellets From the conventional Chulhas used in villages to the more widely used LPG stoves in the cities, emission of greenhouse gases is one of the greatest of concerns of today. Though LPG stoves are said to be most convenient and cause less pollution, studies have shown that these stoves emit 15 times more CO2 than wood and kerosene. LPG contains propane, butane, unsaturated propylene, and butylenes liquefied under high pressure. It is to be kept in mind that even small amount leaks of LPG can be hazardous to the environment. People are increasingly adopting more eco-friendly ways of cooking that reduce environmental pollution, more economical and fuel efficient. 1. Oorja Stove One such environment friendly stove designed by the Indian Institute of Science is the “Oorja stove”. This stove has been proved to be almost smokeless, more efficient, and cheaper in terms of cost when compared to LPG. The fuel is obtained from agricultural waste like bagasse, groundnut husk, or cotton stalks. These wastes are highly compressed and made into pellets which the Oorja stove burns efficiently using an innovative gasification process. Today, over 4,75,000 homes use the Oorja stove across villages in Maharashtra, Karnataka, Tamil Nadu, and Andhra Pradesh. 2. Rocket Stove The “Rocket Stove” is an ecofriendly stove designed by a Japanese health researcher Junji Takano that is not only easy to use but also easy to make and is cost effective. Junji managed to create this “green” stove using large tin cans riveted to the ground. According to Junji, it has high heat transfer capacity causing less pollution which means less carbon dioxide is released into the atmosphere in comparison with a conventional stove. Apparently this Rocket stove is 60% less fuel than the other usual stoves. By using just 500 g of cardboard, one can cook 6 cups of rice and 2 kinds of dishes using this stove. 3. Eco Fire Pot stove “Eco Fire Pot stove” is an environment-friendly stove for a healthy life. Adama Karma is a natural therapist who believes in living close to nature was the one to design this stove. This stove can be made from scrap metals, clay or bricks according to the consumer’s requirements. It looks like a usual LPG stove with two burners with fuel enriched under the burner. Adama claims the fuel to be made from waste vegetable oil mixed with methanol or ethanol and wood ash. The stove can burn for six hours. It turns out that this stove does not emit anything which is harmful if inhaled and is also cost efficient. 4. Score “Score” is yet another ecofriendly stove which uses 1 kg of fuel per hour (wood or dung) created by the researchers of University of Nottingham. The stove is designed not only to produce heat but the heat so produced also gets converted to acoustic energy which in turn is converted to electricity with a linear alternator. This dual purpose stove ensures reduced fuel consumption by three times over traditional stoves and the electrical energy generated can charge 12 V battery, or provide mains AC voltage. Score project has proved to be successful in the rural areas of Kenya, Uganda, and Nepal. 5. Ecofriendly Cooking Stove for Bamburi Moving mountains trust has introduced an environment friendly stove with back boilers which produces hot water as a by-product of their cooking. The stove which is made from clay has a narrow opening to introduce wood as the fuel and a uniquely shaped hob to ensure least heat dissipation. The specially designed stove minimizes fuel consumption, requiring less wood collection and emits very less smoke minimizing bronchial problems. Though this was made specifically for the villagers of Bamburi, it will be a better alternative for traditional Chullas used in other villages. 6. Solar Stove Solar stoves work by harnessing UV radiation from the sun ad converting it to heat. In a country like India with tropical climate, harnessing solar energy is a smart way to control pollution. Though you cannot cook at night and cloudy whether conditions, by resorting to solar stoves as an alternative to LPG or other conventional cooking stoves in rural as well as urban areas (which would be most of the day time), pollution can be curtailed to a great extent. 7. Kenya Ceramic Jiko “Kenya Ceramic Jiko” (KCJ), designed by the efforts of some local and international agencies has become a widely used stove in Africa. It has a unique hour-glass shape different from a traditional jiko allowing maximum heat to be utilized. Also it encompasses a ceramic liner which helps in increasing efficiency at least by 1/4th compared to a traditional jiko. Also, it has been shown to reduce fuel usage by 30-50%. 8. Eco-Chulha The “Eco-Chulha” is yet another stove introduced by Abellon Clean Energy with the motive to provide cleaner solution to counter cooking smoke. The Eco-Chulha is a community stove especially designed to facilitate large scale cooking. It uses “Pellexo” which is a carbon-free pellet-fuel made from forest and agricultural residues. The stove is convenient to use, produces very little smoke devoid of carbon and allows faster cooking which reflects its heat efficiency. 9. Enviro-fuels Stove Enviro-fuels stove will soon hit the market, designed by Enviro Fuels Manufacturing Inc. of Florida. Though, it uses coal as the fuel, they acclaim that the stove is designed to produce maximum heat efficiency and maximum fuel combustion. The company’s president and CEO, Larry Hunt, explained that the fuel produces temperatures as high as or higher than 500 degree Celsius. 10. Electric Cooking Stoves Electric cooking stoves are a great alternative to LPGs in urban areas considering the fact that it does not produce any smoke. The time taken for cooking is faster using an electric cooker. No carbon-dioxide emission means no pollution. Although it has its own disadvantages of cost of electricity consumption, for those who can afford it, it’s a great alternative ensuring cleaner cooking. Resorting to such eco-friendly stoves and eco-sensitive ways of cooking will make a large difference in the years to come.

Changing the water filter, though great for water quality can be wasteful in respect to water quantity. The instructions usually suggest running a new filter through a few times before the water becomes thirst worthy. Next time around, use those extra jugs of waste water to quench the houseplants or the garden or for small and easy cleaning jobs (like rinsing the sink, wiping down the stove, walls or cupboards etc)
