This [[Improved cook stoves|Improved Fuel Stove]], or Rocket Stove, is the final project for [[Engr305]] at [[Humboldt State University]]. The project goal is to construct a demonstration rocket stove for the [[Campus Center for Appropriate Technology]] on the campus of Humboldt State University. The rocket stove will serve as an example of improved fuel stove technology and development; students and public touring the center will learn about the design, function and need for improved fuel stoves around the world. The rocket stove will also enable the residents of the center to cook with traditional [[biomass]], reducing their dependence on petroleum based energy sources. It is important to note that rocket stoves are designed for populations around the world who depend on biomass for their cooking fuel. The use of rocket stoves in developed nations is not necessary. Developed nations using modern cooking methods are not faced with health and environmental issues related with traditional cooking methods. The improved fuel stove was designed, built and tested by Daniel Moyer and Tyler Jones.

It looked like the rocket stove has not been used in quite some time. Reasons for not using the rocket stove is easy of use. Its difficult to light and once it is lit it's hard to stay lit. The bottoms of pots get scorched. It also becomes very smokey when using. The weather has taken its toll on it. I was bummed out that we couldn’t test it out and see actual results. We are planning on going back to do some testing and see how it compares with when it was first built.We will post results once we run some tests.
 
We proceed with the analytical analysis. The first thing that we noticed was the smoke flute and the laminated information were gone. Rust has taken its toll on the stove.The top and bottom have taken the most hit from it. There are some holes from the rust going all the way through the top. So the top will soon need to be replaced. The bottom also has been affected. It appears that the rust has eaten the metal, and is now really thin at the bottom. No holes yet but maybe in the near future. There doesn't seem to be much continuity of the rocket.
Moving on to the combustion chamber. The heat resistant sealant that was used to seal the ceramic bricks is almost completely gone. The bottom brick is also in bad shape. When we wiggled the bottom brick we saw that only one big chunk moved. We also noticed that the back part of the combustion chamber had cracks.
 
Test results will be posted soon.
