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.

Planet Earth. Lets try to promote good tech and warn about and counteract bad tech.

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.”

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".”

Gibson Dunn & Crutcher (gibsondunn.com) is a global law firm, founded in Los Angeles in 1890. They publish a quarterly legal update on "Artificial Intelligence and Autonomous Systems"

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

 
The size of a hydrogen atom, the lightest atom, consisting of a proton and an electron. According to Wikipedia hydrogen atom is roughly 1,1 Å. An Ångstrom is 10−10 m or a ten-billionth of a metre
 
The distance of the hydrogen atoms in a H2 molecule. Pico is 1×10−12 m, or one trillionth (1/1000000000000) of a metre

Hydrogen can be produced by from water by electrolysis even on an industrial scale, with #Hydrogen panels or from hydrocarbons by steam reforming.

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.

“The Hydrogen economy is the use of hydrogen as a low carbon fuel, particularly for heating, hydrogen vehicles,[1] seasonal energy storage and long distance transport of energy.[2]

Hydrogen panels

Researchers from KU Leuven, Belgium have created hydrogen panels, that convert water vapor to hydrogen and oxygen using sunlight.

Hydrogen aviation

ZeroAvia.com has been developing fuel cell-based powertrains for aviation.

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.


Ecological electric

Sodium batteries

  • http://www.broadbit.com/ is a technology company developing revolutionary new batteries using novel sodium-based chemistries to power the future green economy.

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.


Recycling tech

Plastics-to-fuel

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.[3]

Food tech

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.

Cattle emissions

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.

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.”

~ Wikipedia on uses of supercapacitors

Mobility tech

Lists of shared and alternative transport and traveler routers lists carsharing, carpooling and traveler router services around the world.

Ultimate mobility app of the future

w:self-driving cars + w:carsharing fleets + w:peer-to-peer carsharing services integration + w:carpooling services integration + public transport travel routing integration of maximum smoothness.

GoMore.dk already made the "world first" of having p2p carsharing and carpooling in same app. They also offer leasing if you want to be the one sharing your ride. Hooray for Denmark.

They currently work in Denmark, Sweden, Norway, France and Spain.
