power generators
----------------
### fuel-fired generators ###
Electrical energy can be generated at any voltage (LV, MV, or HV)
by fuel-fired generators. These are all capable of burning any type
of combustible fuel, such as coal. They are relatively easy to build,
and so tend to be the first kind of generator used to power electrical
machines. In this role they form an intermediate step between the
directly fuel-fired machines and a more mature electrical network
powered by means other than fuel combustion. They are also, by virtue of
simplicity and controllability, a useful fallback or peak load generator
for electrical networks that normally use more sophisticated generators.
The MV and HV fuel-fired generators can accept fuel via pneumatic tube,
from any direction.
Keeping a fuel-fired generator fully fuelled is usually wasteful, because
it will burn fuel as long as it has any, even if there is no demand for
the electrical power that it generates. This is unlike the directly
fuel-fired machines, which only burn fuel when they have work to do.
To satisfy intermittent demand without waste, a fuel-fired generator must
only be given fuel when there is either demand for the energy or at least
sufficient battery capacity on the network to soak up the excess energy.
The higher-tier fuel-fired generators get much more energy out of a
fuel item than the lower-tier ones. The difference is much more than
is needed to overcome the inefficiency of supply converters, so it is
worth operating fuel-fired generators at a higher tier than the machines
being powered.
### hydro generator ###
The hydro generator is an LV power generator that generates a small amount
of power from the natural motion of water. To operate, the generator must
be horizontally adjacent to water. It doesn't matter whether the water
consists of source blocks or flowing blocks. Having water adjacent on
more than one side, up to the full four, increases the generator's output.
The water itself is unaffected by the generator.
### geothermal generator ###
The geothermal generator is an LV power generator that generates a small
amount of power from the temperature difference between lava and water.
To operate, the generator must be horizontally adjacent to both lava
and water. It doesn't matter whether the liquids consist of source
blocks or flowing blocks.
Beware that if lava and water blocks are adjacent to each other then the
lava will be solidified into stone or obsidian. If the lava adjacent to
the generator is thus destroyed, the generator will stop producing power.
Currently, in the default Minetest game, lava is destroyed even if
it is only diagonally adjacent to water. Under these circumstances,
the only way to operate the geothermal generator is with it adjacent
to one lava block and one water block, which are on opposite sides of
the generator. If diagonal adjacency doesn't destroy lava, such as with
the gloopblocks mod, then it is possible to have more than one lava or
water block adjacent to the geothermal generator. This increases the
generator's output, with the maximum output achieved with two adjacent
blocks of each liquid.
