CAD projects
Still to commence on:
Present projects can be found at:
• http://en.wikiversity.org/wiki/Appropriate_technology_designs
• http://en.wikiversity.org/wiki/Topic:Selfsufficiency
• http://peswiki.com/index.php/Directory:Home_Generation some designs here may be useful as well
Taken up projects
Projects details can be found in the documents in this shared folder.
Images of those documents can be found in this shared folder.
Construction projects
• AT elevator
• Organic buildings
• Settlement design
• Modular kiln
• AT crane
• Watchtower sleeping room
Employment projects
• AT ring spinning frame
• AT loom
• AT sewing machine
Transport projects
• AT sandals; for mere walking near the residence
• The C2C strapon quad roller skates; cradletocradle compliant roller skates
• The AT evelomobile
• The AT mobile shelter
• The AT dicycle; intented for transport in unsafe areas
• The AT electric skateboard
• The human powered vehicles for bicycle sharing systems
• The AT minivan; see also wikiversity)
• The Modular train; a train that can run on any type of rail
•
AT cable car; a vehicle more easy to implement than the freight tram,
at least in certain cities. This as the cable car uses its own lane, and
is thus doesn't clog the streets.
• The AT freight aircraft, see also aircraft for a better understanding of the project
• The AT SP (single person) aircraft: uses only a Beta Stirling engine for propulsion, see
File:SP airplane 1.png, File:SP airplane 2.png (note: untested)
• The AT airship, a design for a 2manned airship
• The AT catamaran; a large seaworthy vessel made at a low cost
• The AT monoxylon; a small vessel for shallow inland waters or lifeboat for larger vessels,
see also File:AT_monoxylon.png
• The AT ship control stand; usable for both watervehicles and LTA aerial vehicles
Energy projects
•
Open design water heater and electricity system (ODWHES): a energy
efficient water heater (gasfired or electrical) combined with a solar
thermal collector and a modular domestic electricity system
• AT solar power tower; a new design for a solar power tower.
• AT solar updraft tower
• Aerial WEH; a kytone
• TreeWEH; a CVTequipped (see comparison of transmissions) thai bladed rotor wind energy harvester
• MicroWEH battery; a rooftop wind turbine, ie for use on skyscrapers
• HP electricity generators for ODWHES
• Direct ethanol fuel cell; can be used to power the AT traction engine, PCBU, ...
•
AT CAD Team/AT IC motor 1 (gasoline); a gasolinetype IC engine,
capable of running on biobutanol, bioethanol, biomethanol, wood gas,
hydrogen, hydrogen peroxide, oxyhydrogen, nitrous oxide, biogas, pure
methane
• AT CAD Team/AT IC motor 1 (Diesel); a Dieseltype IC
engine, intented primarily for running on pure vegetable oil. Can also
be run on biodiesel and the fuels mentioned for the AT IC motor 1
(gasoline)
• AT CAD Team/AT IC motor 2; a quasiturbine type IC engine
• AT CAD Team/TECS steam 1 and 2: 2 models of a thermal energy conversion system
• AT squirrelcage rotor induction motor
• AT brushed electric motor/alternator
Space heating & cooling projects
• Opendesign heat pump
• Deep water source cooling radiator system
• Woodfueled space heating system
Food production (& storage & consumption & preparation) projects
• ISF rice huller
• ISF plough; plough is not appropriate for daytoday use (since notill farming is preferred), but it could be useful in some situations
• AT traction engine: an AT traction engine proposal
• The portable wood gas stove
• AT (microwave) oven
Water supply and distribution projects
• AT spiral pump
• AT water supply pump
• AT irrigation systems
• Treatment pond: see File:AT_Vertical_Flow_reedbed.png
• AT CAD Team/Seawater solar destillation plant
Personal hygiene projects
• AT CAD Team/AT showers
• AT dish washer; see also: Appropriate food preparation, storage, consumption utensils
• Modular solar tracking system; an idea for a modular solar tracking system that can disconnect evacuated tube collector panels. The same idea can btw be used with photovoltaïc solar panels
• AT CAD Team's DIY solar thermal collectors; 2 designs; 1 of a batch heater, the other being a evacuated tube collector
• Communal washing machine
Healthcare projects
• Mummy hammock; a hammock with mosquito net cutout
• AT inhaler, see File:AT_Inhaler.JPG
• Pyrotherapy and isolation sauna, see File:Pyrotherapy_and_Isolation sauna.JPG,
File:Pyrotherapy_and_isolation_sauna_steambath.png
• AT fractionating column, see Ethanol_production
• AT agricultural lands: medicinal, hygiene and IPC crops, see File:Medicinal_and_hygiene_crops.png
Waste disposal projects
• 4 composting toilet designs
• AT incinerator
Ecosystem repair projects
• The Pressurized Cavity for Breathing Underwater (PCBU); used as a movable moon pool, it can speed up coral rehabilitation projects or other projects requiring work below the watersurface
• RO telescope
• The UAS: a remote controlled aircraft, suitable for crop dusting (with organic pesticides), and for remote sensing/environment observation
Miscellaneous projects
• Multipurpose clothing design
• AT prosthetics
• AT electric screwdriver
Purchasing the models
The models can be purchased via Turbosquid , CGTrader or Fastspring.
