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:
“What we call National-Socialism is the poisonous perversion of ideas which have a long history in German intellectual life.”
—Thomas Mann (1875–1955)
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
