A diesel engine in which fuel is injected directly into the cylinder. Wow, that's another one that seems painfully obvious when you write it out. Most of the newer models are "turbo direct injection," which sounds significantly more complicated, not to mention badass.
Industry:Biotechnology; Energy
Substances discharged into the air during combustion, e.g., all that stuff that comes out of your car.
Industry:Biotechnology; Energy
Difference between the fossil energy needed to produce a fuel and the energy the fuel contains
Industry:Biotechnology; Energy
Agricultural crops grown specifically for their energy value.
Industry:Biotechnology; Energy
A number representing the energy stored in a fuel as compared to the energy required to produce, process, transport, and distribute that fuel.
Industry:Biotechnology; Energy
Alcohol containing two carbon atoms per molecule with about two-thirds the energy density of gasoline, mostly fermented from corn starch or sugar cane, also known as ‘grain alcohol’
Industry:Biotechnology; Energy
A fuel derived from the long-ago-dead-and-buried remains of organic life on Earth -- e.g., dinosaurs -- that is generally considered non-renewable. The use of these fuels contributes to pollution and is widely considered a factor in global climate change.
Industry:Biotechnology; Energy
A chemical or heat process used to convert carbonaceous material -- coal, petroleum, biomass -- into its gaseous components, carbon monoxide and hydrogen.
Industry:Biotechnology; Energy
The process of refining natural gas and other hydrocarbons into longer-chain hydrocarbons, which can be used to convert gaseous waste products into fuels.
Industry:Biotechnology; Energy
The point at which a liquid fuel cools to the consistency of petroleum jelly.
