rubber
|
||||
------
|
||||
|
||||
Rubber is a biologically-derived material that has industrial uses due
|
||||
to its electrical resistivity and its impermeability. In technic, it
|
||||
is used in a few recipes, and it must be acquired by tapping rubber trees.
|
||||
|
||||
If you have the moretrees mod installed, the rubber trees you need
|
||||
are those defined by that mod. If not, technic supplies a copy of the
|
||||
moretrees rubber tree.
|
||||
|
||||
Extracting rubber requires a specific tool, a tree tap. Using the tree
|
||||
tap (by left-clicking) on a rubber tree trunk block extracts a lump of
|
||||
raw latex from the trunk. Each trunk block can be repeatedly tapped for
|
||||
latex, at intervals of several minutes; its appearance changes to show
|
||||
whether it is currently ripe for tapping. Each tree has several trunk
|
||||
blocks, so several latex lumps can be extracted from a tree in one visit.
|
||||
|
||||
Raw latex isn't used directly. It must be vulcanized to produce finished
|
||||
rubber. This can be performed by simply cooking the latex, with each
|
||||
latex lump producing one lump of rubber. If you have an extractor,
|
||||
however, the latex is better processed there: each latex lump will
|
||||
produce three lumps of rubber.

electrical power
|
||||
----------------
|
||||
|
||||
Most machines in technic are electrically powered. To operate them it is
|
||||
necessary to construct an electrical power network. The network links
|
||||
together power generators and power-consuming machines, connecting them
|
||||
using power cables.
|
||||
|
||||
There are three tiers of electrical networking: low voltage (LV),
|
||||
medium voltage (MV), and high voltage (HV). Each network must operate
|
||||
at a single voltage, and most electrical items are specific to a single
|
||||
voltage. Generally, the machines of higher tiers are more powerful,
|
||||
but consume more energy and are more expensive to build, than machines
|
||||
of lower tiers. It is normal to build networks of all three tiers,
|
||||
in ascending order as one progresses through the game, but it is not
|
||||
strictly necessary to do this. Building HV equipment requires some parts
|
||||
that can only be manufactured using electrical machines, either LV or MV,
|
||||
so it is not possible to build an HV network first, but it is possible
|
||||
to skip either LV or MV on the way to HV.
|
||||
|
||||
Each voltage has its own cable type, with distinctive insulation. Cable
|
||||
segments connect to each other and to compatible machines automatically.
|
||||
Incompatible electrical items don't connect. All non-cable electrical
|
||||
items must be connected via cable: they don't connect directly to each
|
||||
other. Most electrical items can connect to cables in any direction,
|
||||
but there are a couple of important exceptions noted below.
|
||||
|
||||
To be useful, an electrical network must connect at least one power
|
||||
generator to at least one power-consuming machine. In addition to these
|
||||
items, the network must have a "switching station" in order to operate:
|
||||
no energy will flow without one. Unlike most electrical items, the
|
||||
switching station is not voltage-specific: the same item will manage
|
||||
a network of any tier. However, also unlike most electrical items,
|
||||
it is picky about the direction in which it is connected to the cable:
|
||||
the cable must be directly below the switching station. Due to a bug,
|
||||
the switching station will visually appear to connect to cables on other
|
||||
sides, but those connections don't do anything.
|
||||
|
||||
Hovering over a network's switching station will show the aggregate energy
|
||||
supply and demand, which is useful for troubleshooting. Electrical energy
|
||||
is measured in "EU", and power (energy flow) in EU per second (EU/s).
|
||||
Energy is shifted around a network instantaneously once per second.
|
||||
|
||||
In a simple network with only generators and consumers, if total
|
||||
demand exceeds total supply then no energy will flow, the machines
|
||||
will do nothing, and the generators' output will be lost. To handle
|
||||
this situation, it is recommended to add a battery box to the network.
|
||||
A battery box will store generated energy, and when enough has been
|
||||
stored to run the consumers for one second it will deliver it to the
|
||||
consumers, letting them run part-time. It also stores spare energy
|
||||
when supply exceeds demand, to let consumers run full-time when their
|
||||
demand occasionally peaks above the supply. More battery boxes can
|
||||
be added to cope with larger periods of mismatched supply and demand,
|
||||
such as those resulting from using solar generators (which only produce
|
||||
energy in the daytime).
|
||||
|
||||
When there are electrical networks of multiple tiers, it can be appealing
|
||||
to generate energy on one tier and transfer it to another. The most
|
||||
direct way to do this is with the "supply converter", which can be
|
||||
directly wired into two networks. It is another tier-independent item,
|
||||
and also particular about the direction of cable connections: it must
|
||||
have the cable of one network directly above, and the cable of another
|
||||
network directly below. The supply converter demands 10000 EU/s from
|
||||
the network above, and when this network gives it power it supplies 9000
|
||||
EU/s to the network below. Thus it is only 90% efficient, unlike most of
|
||||
the electrical system which is 100% efficient in moving energy around.
|
||||
To transfer more than 10000 EU/s between networks, connect multiple
|
||||
supply converters in parallel.
