History and Design
The timeline of the development of the lò trấu is unclear, however it is known that the Lo Trau has been in use in Vietnam at least since the 1950s. The fixed version Lo Trau stove is thought to be strongly related to the Castrol stove design of the architect François de Cuvilliés in 1735 and similar European designs in the 1830s, with flue pipes connected to the chimney, oven holes into which concentric iron rings on which the pots were placed. Depending on the size of the pot or the heat needed, one could remove the inner rings. A recent innovation is the portable Lo Trau. Its compact design and efficient operation has been the target of a number of studies. Recently it has been distributed in the Negros area of the Philippines in the The Southern Negros Sustainable Agriculture Demonstration Projects in the 1990s . This relatively late uptake of apparently long-used innovation means the potential of rice husk as fuel has been overlooked by many for a long time, as well as the obscurity of the Lo Trau designs to the wider world.

Famous quotes containing the words history and/or design:
“the future is simply nothing at all. Nothing has happened to the present by becoming past except that fresh slices of existence have been added to the total history of the world. The past is thus as real as the present.”
—Charlie Dunbar Broad (18871971)
“The reason American cars dont sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. Thats why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
