Efficiency
Open fire has four major disadvantages: It is dangerous, it produces much smoke, soot blackens the cookware, and the heat efficiency is poor. The enclosed design of the Lo Trau means complete combustion of the fuel, better use of the heat that it generated and thus reduce the fuel consumption by its furnace-like burning generated by the updraft through the chimney. Due to its furnace-like operation, most fuel will burned thoroughly into fine ashes with almost no waste. In situ test findings showed that it took only 5 minutes to boil water using an approximate 180g of rice husk. This figure is impressive when compared to liquefied petroleum gas (LPG), fuel wood, and charcoal stoves, which required 5, 15, and 20 minutes respectively to boil the same amount of water. It should also be noted that at the present time both wood and charcoal fires are frequently ignited using kerosene, a cost that would be eliminated with the rice husk stove.

Famous quotes containing the word efficiency:
“Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and the same in her efficiency and power of action; that is, nature’s laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through nature’s universal laws and rules.”
—Baruch (Benedict)
“I’ll take fifty percent efficiency to get one hundred percent loyalty.”
—Samuel Goldwyn (1882–1974)
““Never hug and kiss your children! Mother love may make your children’s infancy unhappy and prevent them from pursuing a career or getting married!” That’s total hogwash, of course. But it shows on extreme example of what state-of-the-art “scientific” parenting was supposed to be in early twentieth-century America. After all, that was the heyday of efficiency experts, time-and-motion studies, and the like.”
—Lawrence Kutner (20th century)
