    “Technology ("science of craft", from Greek τέχνη, techne, "art, skill, cunning of hand"; and -λογία, -logia|) is the collection of techniques, skills, methods, and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation.”

    ~ Wikipedia on technology

    This article aims to gather tech relevant for the well being of the populations and the planet. Technology can be used for good and evil this is a good reason to keep up-to-date on the problems and opportunities and good solutions.

    Consumerium tech

    See systems selections for newest going ons


    Automation

    “Automation is the technology by which a process or procedure is performed with minimal human assistance.”

    Automated locking system makes bikesharing efficient.

    AI

    “Artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and animals. Colloquially, the term "artificial intelligence" is used to describe machines that mimic "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving".”

    AI is can be divided to multiple subfields:

    • w:Expert system is a computer system that emulates the decision-making ability of a human expert. ( Wikipedia )

    Ecological tech

    There are various interesting ecological technologies being piloted.

    Hydrogen purified steel

    HYBRIT an abbreviation of HYdrogen BReakthrough Ironmaking Technology, where iron for steel making is not purified by a process called coking, but instead using massive amounts of hydrogen to purify it.

    w:SSAB and partners are building a small-scale pilot production line in Luleå, Sweden, slated to be launched in 2020.

    Food from air and electricity

    In Finland Solar Foods Ltd. has demonstrated making protein called Solein with renewable electricity and CO2 as raw material and are building their first real plant soon.

    Water demand of this new method is fraction of plant-based nutrition, let alone meats and it is slightly CO2 negative if the electricity is not from CO2 emitting power plants.

    CO2 capture

    CO2 capture can refer to capturing CO2 from an industrial process or just grabbing it from air.

    Power-to-gas

    Power-to-gas technologies are advancing. Power-to-gas involves energy losses in the conversion, but the power of gaseous energy that it is much cheaper to store than electricity, plus the distribution networks largely exist already.

    Potential target fuels are hydrogen and methane. Hydrogen is being mixed into natural gas networks in Germany with no negative side-effects.

    w:Methanation is the process of making methane from carbon oxides and hydrogen. Methane is a drop-in replacement for LNG and therefore could help us away from fossil dependence/capitalism. The price of proton-exchange electrolyzers has dropped by roughly 40 percent during the past decade the Scientific American Reports

    Converting excess electricity from solar and wind farms to gases may be a very good idea as they can then readily be used to produce electricity during low-output times of solar and wind energy and because the systems to store the gas already exist.

    Hemp tech

    Development of sound hemp products has suffered from the prohibition of the plant since 1937

    Wikipedia's list of hemp products is not complete by a far shot.

    Hemp wood

    From seed to building material in less than a year is a reality in Kentucky as the first HempWood factory has opened. HempWood is said to have slightly better characteristics than oak.

    Hempcrete

    w:Hempcrete is a w:bio-composite material for construction.

    Hemp supercapacitors

    “A supercapacitor is a high-capacity capacitor with a capacitance value much higher than other capacitors, but with lower voltage limits, that bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries.”

    ~ Wikipedia on definition of a supercapacitator

    “Supercapacitors are used in applications requiring many rapid charge/discharge cycles, rather than long term compact energy storage — in automobiles, buses, trains, cranes and elevators, where they are used for regenerative braking, short-term energy storage, or burst-mode power delivery.”
