Activity Analysis: The Work Space Module
This is the intellectual and control centre of the dwelling. It is a place of quietness and concentration; a place to research and study; a place in which to invent and design, to formulate plans, crystallize ideas and connect with the world.
On the right is a plan view is of the dwelling's Work Space. The curved green enclosure to the right, spanning the 90° arc between the two windows, provides a continuous desk surface and storage for books, stationery and equipment. Between each passage and its adjacent window is a floor to ceiling book case unit. The curved green unit, spanning the 90° arc between the two passages, is the Laboratory work bench and cupboards. In the centre of the Work Space is a console containing five work stations used for computing, communications and navigation.
The Work Space's 7-segment central console is shown on the left. It is rotating in order to show details of its 5 equipped segments. Three of these are computer work stations. One of the remaining 2 is a printing and scanning station. Another is a communications and navigation station. Each equipped segment has a pair of standard 23-inch rack rails at the rear, between which up to 3 standard flat-format 23-inch equipment cabinets may be mounted. Two of the 7 segments are unequipped to allow access.
The outer radius of the console is 2½ metres. The desk sectors are 75 cm deep. This leaves the inner circle of the console with a radius of 1·75; metres to give adequate space for chairs and personal access.
On the right is a plan view of the console, which is oriented to be consistent with the plan view of the whole Work Space module shown above. The two computer segments that are next to each other are straight-forward PC workstations. They have access to the console's local-area network and may be switched off when not in use. The segment diametrically opposite these two is also a computer station. However, this computer hosts various servers. It is therefore kept running all the time. This computer also acts as the dwelling's router, which provides access to the outside world.
The view on the left shows one of the two normal computer stations. A monitor screen is mounted on the central rack-rails of each station. The height of each screen can be adjusted independently to suit each human user. Each station's computer is housed in a standard flat-format 23-inch cabinet set above the screen. The cabinet shown below desk level houses a battery back-up power supply and cooling system for the screen and computer. A keyboard and mouse are placed on the table in front of the screen.
A loudspeaker is fixed to each rack-rail just above the screen to provide local sound. Additionally, each computer workstations has a headset (headphones with a boom microphone) for private listening and voice communication. This normally hangs on a hook fixed to the side of the vertical divider panel at the left of the workstation's desk area. Headset cables are normally connected to the left earpiece.
Diametrically opposite the above pair of PC workstations is the server/router station shown on the right. Although it can also be used as a general purpose PC workstation, the server/router station's main roles are as follows: 1) running on-line servers such as web, FTP, eMule, gnutella and G2, 2) running a local area network (LAN) router serving the other two workstations and the printer/scanner station and 3) running an infrastructure router which acts as a 3-way junction in our Landshare World's global network. For this reason it is generally kept running continuously.
On the right of the server/router station is the printer/scanner station as shown on the left. I can never decide whether I prefer a separate printer and scanner or a device which incorporates both. Both options have their different merits. On the left, it is a combined unit that is shown in the middle of the segment's desk space. Its printing and scanning services are made available to the workstations via the local area network. Stationery and consumables for the printer and scanner are stored within the confines of the segment.
There is plenty of room around the circular corridor outside the console to access the rear of each flat-format computer cabinet for maintaining and upgrading the equipment. All power and signal cables are channelled neatly within a cable gully along the outer circumference of the desk surface. From there, they run up the insides of the hollow rack rails to the equipment cabinets. Cooling fans from all equipment cases have a clear exhaust path into the large peripheral corridor around the console.
The dwelling's means of navigating and of communicating with the world are accommodated within the Nav/Com segment of the console. Uniquely, this segment has two sets of vertical rack rails: one for navigation equipment and one for communications equipment.
In Landshare World, there is a communications infrastructure, which fulfils the role currently fulfilled by the Internet. It is not, however, safe or expedient for landshare dwellers to be dependent upon the services or subjected to the ulterior motives of corporate or State interests. The Landshare Internet is therefore based on a distributed millimetric radio network in which each dwelling is an active node.
For this purpose, 3 radio-frequency (RF) modems are housed in the upper right-hand cabinet of the comms segment. Each of these highly sophisticated and configurable modems is connected by a LAN cable to a router socket on the server/router computer. The co-axial input and output of each modem are connected to each of 3 millimetric radio transceivers in the same cabinet. These in turn are connected to dish aerials mounted in the roof of the Work Space module.
Each of the three millimetric transceivers forms one end of a point-to-point communications link between this Landshare dwelling and one of 3 neighbouring Landshare dwellings. Thus is formed a worldwide wireless network of low vulnerability. Its much larger number of nodes makes it somewhat slower than the present-day Internet. Notwithstanding, its lack of speed is well overcome by adopting a different paradigm for distributing information.
The high bandwidth communication, provided by this Landshare "Internet", is not always necessary. But direct ultra-reliable low bandwidth communication, which the Landshare "Internet" cannot provide, sometimes is, especially in emergencies. For this reason, the communications segment also contains low, medium, high frequency and VHF equipment, which exploit the facilities nature provides for infrastructure-independent communication.
For this purpose, the communications segment also contains communications equipment covering the long wave (low frequency), medium wave (medium frequency), short wave (high frequency) and VHF. Included in the cabinets are front-ends and converters reaching up to 2 gigahertz.
To be able to transmit and receive radio signals effectively, these equipments must be coupled to the universe via appropriate forms of electromagnetic transducers. Depending on the part of the radio spectrum concerned, these transducers can be variously aerial wires, rod antennas, magnetic loops, dipole-fed multi-element arrays and waveguide-fed dishes, plus other exotic concoctions.
Rod antennas of various sizes are built into the space above the ceiling of the Work Space module. These extend upwards through the roof above and can be retracted by motors, which also close the roof opening during storms. Magnetic loops of a broad range of sizes are built into the fabric of the dwelling. Dish and array antennas are also accommodated in the space above the ceiling of the Work Space module.
The Earth's Ionosphere offers a more direct and infrastructure-free means of communication. It can, however, be a fickle friend. Long-range communication paths open and close arbitrarily at different frequencies. Finding the optimum working frequency between two locations - at different times of the day, year and solar cycle - requires much knowledge, skill and patience.
For this reason, HF communication has a permanent element of on-going research. Hence research is also a function of the communications segment. To maintain a reliable channel, it is generally necessary to use multiple-diversity links. That is, having equipment working on more than one frequency at a time, so that, when one or more channels fade out, at least one other is still open.
Research also continues into different ways of using the short wave spectrum, such as sharing the space via a chip-coded spread spectrum regime to offer both reliability and privacy. And underpinning all is an on-going programme of research into the electric and magnetic aspects of the Earth's atmosphere, and indeed, of the universe beyond.
Landshare society is semi-nomadic. For this reason, the dwelling is vehicular. It is able to move from one location to another. For this it needs a means of navigation and flight control.
A diversity of active conventional means of navigation are installed in the so far unused tower units in the vertical side cabinets of the central console. These include a compass, sextant, inertial platforms, radio aids and GPS. They also include research devices for new experimental means of navigation such as neural network based landscape recognition, geo-sonic resonance, pulsar signature recognition and automatic optical star fixing.
The aim of these new experimental methods is to make dwelling navigation as independent as possible of artificial infrastructure. Some of these tower units also contain devices for invoking and controlling the dwelling's motive power.
Within the dedicated Laboratory space, shown on the left of the plan view, the residents monitor and control the general operation of their dwelling and gleba. Herein also they do special projects that are of particular interest to them. Projects are of two types:
those that are essential and common to all landshare-based dwellings and
those that are of specific interest to the particular occupiers of this dwelling.
The first type includes monitoring and control units for all the essential systems and services within the dwelling such as electrical power and lighting, heating and cooling, air circulation and filtering, vacuum services, water and waste, sound and communications, and surveillance.
The first type also includes apparatus for monitoring a multiplicity of parameters fed from sensors throughout the gleba.
Among these are devices for monitoring and analysing natural resources, climate and crop health both in the field and in storage. Software is used for analysing raw data. For example, a neural network program is used to analyse the spectrum of reflected light from a crop to determine its condition and readiness for harvesting. Other software is used for analysing soil and climate to determine the best crop mixes and rotations for the particular gleba.
Particular instances of the second type of project depend on the personal interests of the residents. I would like to work on the development of a fractal architecture for a global communications network that would link all landshare-based dwellings seamlessly, rendering them immune from State and corporate invasion of personal peace and privacy.
This gleba-based dwelling is designed to be self-sufficient in maintenance and repair. Its occupiers therefore need to be equipped to keep the shell and all its systems in good repair and working order without any help from outside services. This is the purpose of the workshop.
Each of the 6 sections of the workshop's peripheral cupboard contains a workstation with a particular speciality. Examples of different possible specialities are:
This workshop is thus equipped to maintain and repair (and possibly construct) all types of items and devices used within the farmlet. These would include:
- Electronics work bench,
- Fitter's work bench,
- Drill press and routing machine,
- Light engineering lathe,
- Radial-arm saw bench,
- Welding/brazing bay.
- furniture and domestic appliances,
- computer, communications, monitoring and surveillance equipment,
- alternative energy generation, storage and distribution systems,
- water and sewage processing systems,
- small subsystems and components from vehicles and farm equipment.
The workshop is located in a separate room at ground level beneath the main work space and is accessible only via its own separate outside door. It includes new forms of machine tools made of triangulated tubing of light metal alloys or strong composite materials, with mild or tool quality steel being used only for tools and hardened work surfaces.
The workshop should perhaps be the first space in the dwelling shell to be equipped. The facilities of the workshop could then be fully utilised in the construction of the other spaces and infrastructures of the dwelling.
