“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.”
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.

“Automation is the technology by which a process or procedure is performed with minimal human assistance.”
“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:Machine learning (ML) is the scientific study of w:algorithms and w:statistical models that w:computer systems use to effectively perform a specific task without using explicit instructions, relying on patterns and inference instead. ( Wikipedia )
- w:Natural language processing (NLP) is a subfield of w:computer science, information engineering, and w:artificial intelligence concerned with the interactions between computers and human (natural) languages, in particular how to program computers to process and analyze large amounts of w:natural language data. ( Wikipedia )
- w:Expert system is a computer system that emulates the decision-making ability of a human expert. ( Wikipedia )
There are various interesting ecological technologies being piloted.
Hydrogen fuel produced from (locally) harvested energy either by hydrogen panels or electrolysis plants can be considered and is being widely marketed as carbon-free, whereas steam reforming from other fuels causes carbon emissions.
Researchers from KU Leuven, Belgium have created hydrogen panels, that convert water vapor to hydrogen and oxygen using sunlight.

Hydrogen purified steel
HYBRIT is 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.

Plant-based batteries and 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.”
“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.”
Spent hemp has been studied for use in electrical engineering.

- VTT Technical Research Centre of Finland blog post "Greener electronics from spent grain and pine bark" states that VTT and Aalto University have joined the Academy of Finland's FinnCERES flagship programme to study the possibilities of using biocoal made from brewery waste and pulp mill waste to make batteries, w:supercapacitors and solar panels.
CO2 capture can refer to capturing CO2 from an industrial process or just grabbing it from air.
- FastCompany.com article 'We have the tech to suck CO2 from the air–but can it suck enough to make a difference?' (2019)
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.
Researchers from Purdue University have developed a technology entitled 'Use of Supercritical Water for the Liquefaction of Polypropylene into Oil' that works on polyolefin waste, the sort of plastic used for grocery bags, toys, and shrink wrap. This sort of plastic accounts for about 23% of plastic waste, according to researchers who describe the process in a paper published in Sustainable Chemistry and Engineering, a publication of the American Chemical Society. The new technique uses a process called hydrothermal liquefaction, in which very high temperatures melt pellets of polyolefin and then dissolve them in water. The by-products of this process are oil, gas, or solvents.

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.

According to Australian research, if 2% dry matter of the Asparagopsis taxiformis seaweed is added to cattle fodder, the bovines' methane production falls to a tiny fraction (fall of 98.9%) in 72 hrs compared to cattle fed with traditional feed.
- 'The red macroalgae Asparagopsis taxiformis is a potent natural antimethanogenic that reduces methane production during in vitro fermentation with rumen fluid' was published in Animal Production Science, a journal by CSIRO Publishing in February 2016

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.
