Chapter 8
The micro-engines work using similar principles as their large-scale counterparts. They
suck air into a compressor and ignite it with fuel.
The compressed air then spins a set of
turbines that are connected to a generator to generate electrical power. The fuels used
could be hydrogen, diesel based, or more energy-dense solid fuels. Made from layers
of silicon wafers, these tiny engines are supposed to output the same levels of electrical
power per unit of fuel as their large-scale counterparts.
Their proponents claim they have two advantages. First, they can output far more power
using less fuel than fuel cells ...
