List of obsolete technology

This is a list of obsolete technology which includes newer technologies that replaced the older ones. Many technologies that have newer alternatives have not been completely replaced.

Obsolete technology Replacement Still used for
Bathing machine No longer required due to changing social standards of morality
Drive-through bank teller (sometimes featuring pneumatic tubes to transfer documents and money to outer lanes) ATM (drive-through or walk-up), online banking Drive-through tellers still exist to serve customers who prefer not to use the available technology or to handle transactions too complex to be handled by an ATM.
Hourglass Clock Tasks where a fixed amount of time can be measured with a low-tech solution: Exposure time tracker in saunas (where electronics might be damaged by the heat or ultraviolet light), retro kitchen timers, board games
Manual vacuum cleaner, carpet sweeper Electric vacuum cleaner Carpet sweepers are sometimes used in commercial applications (like movie theatres) where the noise of an electric vacuum is unwelcome
Primitive Fire making Ferrocerium, Match, Lighter Practiced as backup survival skills if advanced methods unavailable.
Quill pen, reed pen, dip pen, fountain pen Ballpoint pen Calligraphy, personal preference
Sundial Clock
Outhouse Flush Toilets, Sanitary sewers, Portable toilet Remote or undeveloped locations far from sewage systems.
Swamp cooler Air conditioning Dry climates
Lighting
Incandescent light bulbs Fluorescent lamps, cold cathode lamps, high-intensity discharge lamp, LEDs Specialty purposes; mandatory phase-out of incandescent light bulbs is happening in some countries. LEDs are also gradually replacing compact fluorescent lamps.
Moonlight towers Distributed street lighting
Producing light with fire. Early: candles, torches. Later: kerosene lamps, fuel-based lanterns, and gas light Flashlights, electric lights Torches sometimes used for performance purposes. Coleman Lanterns and similar are sometimes used for camping, but battery-powered lanterns are becoming more common. Gas lighting is still used for street lighting in some historic districts, but not indoors due to toxic emissions. Candles are still used for aesthetic purposes.
Kitchens and cooking

Pneumatic tubes for moving documents and postal items Electronic communication, mechanized surface vehicles Transport of physical items in hospitals and factories, scientific applications; Possible revival as a means of high-speed transportation
Typewriter Word processor Still used by some writers being deliberately low-tech
Slide rule, mechanical calculator Electronic calculator, computer
Vacuum tube Transistor Vacuum tubes are still used in microwave ovens, RF communications and radar, high power industrial switching such as in pulsed lasers and generation of x-rays. They have found niche popularity in more expensive guitar amplifiers and hi-fi power amplifiers.
