The MOSS Grads with Dr. KeithThomsen

MOSS Explorers: Breaking it down

  On the second day of our adventure we visited with Keith Thompson who talked with us about the process of converting woody feedstocks to bio-fuel.  One of the things we discussed was the difference between bio chemical and thermo chemical treatments (gasification, pyrolysis, and liquefaction) of the biomass.  The bio chemical conversion process uses…

MOSS Explorers: Checking out airplanes

In the Alaska Airlines headquarters! I know it’s only a model, but check out the plane in the video. The “scimitar winglets” at the end of the wings cost about a million dollars to build and install, but the money that they save by reducing wind resistance easily pays for the cost in one year.…

MOSS Explorers: Life Cycle Assessment

How green is green? If we compare biofuel against fossil fuel, which one is environmentally friendlier than the other? Comparing the carbon released during combustion does not provide a full picture of carbon footprint of either fuel. Materials had to be collected, transported, refined, and transported again before they reach their final destination as fuel…

MOSS Explorers: Conversion Process

The second step in the process from wood to wing is the conversion of the woody biomass to bio-fuel.  There are three basic types of biomass that can be made into bio fuel, starchy, triglycerides, and lignocellulosic feedstocks.  Lignocellulosic biomass is the most abundant type of biomass and the most commonly used to make bio-fuel.…
