Biomass - Usage of tall size of local resources ①

I think that the use of biomass should be the subject of heat use. In fact, we live in an old house in Satoyama, have a bath, a kitchen, and a heating for firewood, but we need roughly 10kg a day for one agricultural container. Because the amount of heat changes in serrata, Cedar, and cypress, it is not to be said unconditionally. Because it is a warm Shizuoka, 10kg in winter, about half in summer.
　By the way, the furnace of "Love Agriculture Furnace" is developed after the war and the efficient furnace is made, and it uses it. The current housing consumption is 80 giga Joules. This is the kerosene equivalent of 6 liters a day. The wood pellets are about half the amount of heat of kerosene. 10kg = about 10 liters, so the firewood is about 5 liters of kerosene.
I think it's a reasonable line. The specific gravity of cypress is 0.41 t/m3. That is, it weighs 410kg per cubic metre. If it was roughly 400kg, 0.025 cubic meters. Roughly, it becomes a log of 40 cm in diameter and about 30cm in height. I can understand this size as a feeling. It is 3650kg per year, even if it is 10kg per day throughout the year. About nine cubic meters.

　I think the summer is about 6 cubic meters. The solar water heater has not been applied yet, but Shizuoka has a high weather rate, so it is not necessary to cook the vacuum tube in winter. With a solar water heater, the amount of firewood per year will be about 4.5 cubic meters. 1.8 m x 1.5 m x 0.4 m = 1.008 cubic meters of shelves should be five minutes.
