Beside the different technical structures both models also differ in power
transfer and efficiency. For the same amount of power the Steam Box
model needs more fuel then the D 20 model. The generator is excellent to
explore the power transfer.
1.4 What function has the steam engine nowadays?
In the area of the power engines the steam engine was substituted through
the combustion engine. Because of the high energy content of the fuel (10-
12 kWh per litre) one gains a higher efficiency together with less weight
and more comfortable operation. Today there are still areas of use for the
steam engine. These constructions are used in the coal mining and conveyor
belts. Here the steam engine works as well as a winding machine for coal
and at the same time as a brake to let down filling material. The kinetic
energy which is produced through the letting down movement is used to
heat up the steam.
Now and again there are engineers who pick up the principle of the steam
engine and bring it into the world with modern materials. One advantage to
the combustion engine is the external combustion process and the use of a
variety of fuels. Another one is the overload capacity of the steam engine.
Overload capacity means that the nominal value and the continuous power
transfer can be shortly and without problems exceeded. One can prove this
in the described experiments, f. ex. by short-circuiting the generator.
Modern steam engines with low emission combustion produce steam
efficiently and then similar like a diesel engine they inject the steam
through nozzles. Those engines work in the 2-stroke process and do not
need common lubricants, because the mechanical parts are made out of
carbonic components.
1.4.1 Hybrid systems consisting photovoltaic constructions and
the steam engine
There exist different explorations and examinations regarding to hybrid
systems consisting modern photovoltaic in combination with modern
concepts of the steam engine.
These combined systems make sense in climate regions where solar energy
mainly is used in the summer season and a complement is needed for the
