About Efficiency of Wood Burning Fisher and EPA Stoves




Fisher wood stoves released about 50 – 80 grams of smoke for every kilogram of wood that was burned. By closing steel chimney off and limiting release to only a small hole, 6 inches in diameter, the heat would be retained in the room. It’s very important to underline that the new clean burning Fisher stove released less than 6 grams of smoke on every 1 kilogram of wood that was burned. These new clean burning stoves are known as EPA outdoor wood stoves.

The fire could also be controlled more easily. In addition, these new wood stoves could easily be used for cooling. Fisher wood stoves were made from heavy steel plates ¼’ and 5/16′ thick. The doors were made of cast-iron. Bob Fisher gave the original names for the models of stoves. They were “Papa Bear,” “Momma Bear” and “Baby Bear.” Nowadays the stoves designed by Bob Fisher are manufactured no more. However, they are still sold as vintage goods and have become collectors’ items.
In the mid-1980s the old wood stoves were replaced by clean burning stoves.

As for the design, the design of the Fisher stove was based on observing how heat was lost from a wood burning fireplace. The Fisher wood stoves had a plume-pipe that extended from the top of the steel box structure and released the smoke outside. Older models had steel doors. Newer models had heat resistant glass doors to show the fire within.

The Cactus Family - Cactaceae




The scientific name of the cactus family Cactaceae is.The Cactaceae are mostly spiny succulents with photosynthetic stems that are a little more than 100 genera and species from 1500 to 1800 (Neffeler 2002).
A succulent is a plant that stores water for times when water is scarce.They are commonly found in arid environments such as deserts or semi-desert.They can also live in areas of extreme rainfall, but unreliable (as when it rains only once or twice a year in quick bursts).The cactus plants are among the most remarkable and characteristics of hot and arid areas of the New World (Nyffeler, 2002).

The cactus family is entirely of U.S. origin.Most species of cacti occur on the ground while few can be found in the leaves of trees in tropical rainforests (Zomlefer 1994).Centers of diversity, arid regions of North and South America, including the southwestern United States and Mexico, eastern Brazil and eastern and western slopes of the Andes of South America (Nyffeler 2002.)

Others may occur in the Eastern and Middle Western U.S. The northern boundaries of cacti including Washington, Minnesota, Wisconsin, Massachusetts and even the Canadian provinces of British Columbia, Alberta and Ontario when they go south to the aforementioned fields of South America ( Benson 1969).

In the U. S. , The cacti are most abundant in Arizona, Texas and parts of southern California and New Mexico (Bowers, Burgess, & Turner 1995).The most remarkable species of cactus in the appeal stage is gigantic sequaro (Carnegia gigantea), considered the most succulent in the U.S. (Kearny, Peebles, 1969).

KEEPING CACTUS ALIVE IN WINTER




During the dormant period (winter) your cactus should be watered only enough to prevent it from shriveling. Don't water at all if it is humid for an extended period. During dormancy water is not taken in as rapidly by the plants roots, nor does it evaporate as quickly, and the result might be root rot. If possible bring your cactus inside the house and place it by a sunny window so it can continue to grow (slowly) through the winter. There are however other methods, as this cactophile explains.

Cacti are well suited to being packaged for extended periods without light or water, they will almost always arrive at your house in good condition. As most species are cold resistant, they can be shipped any time of year. Since Cacti are tough and hardy, they don't have to be shipped by an overnight service, like most tropicals.

About a couple weeks before the first hard frost (see Farmer's Almanac for dates) make sure that the soil dries up completely (shielding the plants from rain if required). Then just move the containers inside my garage to protect the cacti from freezing. The temperature in the attached, but unheated garage drops to about 38 degrees during the coldest part of Winter. There is no window, or lights available. The cacti remain sheltered in the garage, in total darkness, all Winter until you bring them out in the Spring after all danger of frost is past.

You can keep them under a shaded patio for a week or so, and slowly move them to partial direct sun, then full sun over the course of two weeks (they are subject to sunburn if exposed to direct sun immediately after emergence from the dark.) They are watered lightly each week unless water is provided naturally by rain.

When they are accustomed to full sun (May / June in my zone 5/6 location) you can use Miracle Grow plant food (as directed for container plants, even though they are exposed to the rain outdoors.) Then you should repeat fertilizing every 3 weeks or so during the Summer.

By July there is usually some good new growth which is very explosive in August and continues (slower) into late September. By late October the cycle continues and they are again placed in the dark shelter of a garage.
