Biogas from cactus is a TechnologyLandmark for use in an OmegaMap. The information is derived from an article written by Sean Fleming on March 22, 2019 and presented by the World Economic Forum.

Since 2016 a new form of biogas has been used in Mexico to power agricultural equipment. Rogelio Sosa López, is a farmer and tortilla producer from Zitácuaro. He was always searching for new ways to keep operating costs down. Working with a colleague, Antonio Rodríguez they pulped cactus to make biogas.

It is now being used by the city of Zitacuaro to fuel a fleet of its vehicles. The fuel is made by a company called Nopalimex. The fuel has a number of advantages. Its functionality is improved – it costs about $0.65 per litre which is about one third cheaper than gasoline or diesel. It is said to burn much cleaner than conventional fuel. It is derived from a biological source, the prickly pear, commonly called the nopal and more formally Opuntia. This source grows prolifically to a height of seven or eight metres. Furthermore the nopal grows in areas not used for the cultivation of food.

Biogas from cactus contributes to the functionality of Process-Energy. Its position in the Functionality Grid is illustrated below. Its level of maturity is estimated at a technology readiness level of TRL 7. This level is described as: “System prototype demonstrated in operational environment”.

Biodegradable plastic from cactus has been identified as a Technology Landmark for use in an OmegaMap. If this technology succeeds it will lessen the accumulation of plastic pollution at present afflicting the ecosphere. The information source for this sketch is an article “This Mexican is making biofuel from cactus plants” written by Sean Flemming on March 22, 2019 and published in the World Economic Forum. Background information is contained in an article entitled “Nopal juice forms basis for new biodegradable plastic” published in Mexico News Daily on June 12, 2018.

Sandra Pascoe of the University of the Valley of Atemajac used the juice from the Nopal cactus to form plastic sheeting. She is now cooperating with the University of Guadelajara Centre for Biological and Agricultural Research.

The Nopal juice contains “…monosaccharides and polysaccharides, which can be combined with glycerol, natural waxes and proteins to create a liquid that forms into plasticky sheets.” These plastic sheets decompose naturally when buried.

The functionality that this invention is focused on is ProcessMatter. Its position in the functionality grid is illustrated below. Details of functional performance metrics are not available at this stage.

The technology readiness level (TRL) on a scale of 1-10 is judged to be TRL 4 “Technology validated in lab”.

ENERGY INDEPENDENT TREATMENT OF EFFLUENT

Seaside located effluent treatment that does not rely on an external energy source has been identified as a Technology Landmark for an OmegaMap. Its successful application would lessen the pollution caused by interruptions in power supply which result in untreated effluent being discharged into the ocean.

The information presented here is sourced from an article written by David Szondy, “Blue power”could make wastewater plants energy-independent”, New Atlas, July 30 2019.

Research at the University of Stanford has pointed to a process that is energy independent and carbon neutral. Its principle of operation is to use the salinity gradient that occurs when effluent is mixed with seawater. When this mixture is washed over electrodes made of Prussian Blue and polypyrrole, a battery is created.

The functionality focus is Process-Energy. Its position in the Functionality Grid is illustrated in the diagram below.

Two functional performance metrics (FPMs) can be considered. A functional performance metric that is used to express the reduction in energy needed for producing one unit of treated effluent. This would reflect an increase to the theoretical limit as external energy input becomes zero. Another functional performance metric could be output of energy related to the input of effluent. In this case: 0.65 kW/h of electricity per 1 cubic meter of effluent. Data on the improvement of this ratio is not available. 

The Technology readiness level on a scale of 1-10 seems to be at TRL 4 – i.e., “Technology validated in lab”.

STEEL BLAST FURNACE POWERED BY HYDROGEN

Steel blast furnaces powered by hydrogen would contribute significantly to a reduction in carbon emissions. This development is considered a Technology Landmark for an Omegamap.

The information presented below is based on an article; “How to Power a Steel Blast Furnace Using Only Hydrogen” written by Carolene Delbert on November 15 2019, in the Popular Mechanics Newsletter. This was based on an article published in Renew Economy written by Michael Mazengrab on November 13 2019. It was brought to our attention by Alan Brent in a post on LinkedIn.

Steelmakers in Germany moved toward carbon neutral steel production by using hydrogen to power a blast furnace. The company, ThyssenKrupp at its facility in North-Rhine Westphalia, used a new principle of operation. In its “furnace 9” it fed hydrogen into one of 28 tuyeres, or nozzles, that otherwise supply coal into the blast furnace. Following the successful trial, ThyssenKrupp plans to scale up the injection to all 28 tuyeres within the furnace and aims to eventually run at least three furnaces completely on hydrogen by 2023. It has committed to reducing emissions by 30 percent by 2030.

The functionality focused on here is Process-Energy. It is illustrated in the Functionality Grid below. To make 1000 kilograms of steel requires 780 kilograms of coal. Data could not be found on the input requirements of hydrogen. It is therefore not possible to calculate Functional Performance Metrics. However the company aims to be carbon neutral by 2050.

The technology readiness of this innovation is judged to be TRL 5 on a scale of 1 to 9, i.e. “Technology validated in relevant environment”.

LASER BEAM BOOSTS HARD DISC DRIVE

In an article on the Seagate Blog, December 2, entitled “HAMR Milestone: Seagate Achieves 16TB Capacity on Internal HAMR Test Units”, John Paulsen describes an enhanced hard disk drive. It has been identified as a Technology Landmark for an OmegaMap.

The abbreviation HAMR stands for Heat Assisted Magnetic Recording. “HAMR uses a new kind of media magnetic technology on each disk that allows data bits, or grains, to become smaller and more densely packed than ever…” The essence of the innovation lies in the principle of operation. A laser beam is used to heat tiny spots on the disk.

The functional performance metric is terabytes per drive. The units described by Paulsen store 16TB per drive. These are internal test units. The company is working on 20TB per drive by 2020. These units will be delivered at the same size as a conventional hard drive.

Their technology readiness level is judged to be TRL4, i.e., “Technology validated in lab”.

FOREST THERAPY: USING THE HEALING POWER OF TREES

Flag

The book Forest Bathing by Dr. Qing Li, Chairman of the Japanese Society of Forest Medicine, describes a medical technology landmark. It is considered a Technology Landmark for an OmegaMap.

The description starts with the natural pleasant sensation that many people have, while spending time in a forest. The five human senses can all come into play –  sight, hearing, touch, smell and taste.

The book then turns to aspects of healing. These include; reduced blood pressure, improved cardiovascular and metabolic activity, lower blood sugar levels, increasing the count of natural killer cells, and increasing  production of anti-cancer proteins. These have been scientifically observed by comparing the profiles of people who have engaged in forest therapy with the profiles of control groups. The former significantly outrank the latter.

This leads to a fundamental question. Is there  a physically identifiable emanation in a forest that carries the healing power? The answer suggested is “yes”. It is called phytoncide and is produced by trees to protect them from afflictions. Scientific studies have shown that phytoncides can be of benefit to humans as well. While research is ongoing we should regard available evidence as pointing to a medical technology landmark.

Forest therapy contributes to the functionality of Process-Matter. Its position in the Functionality Grid is illustrated below. Its level of maturity is estimated at a Technology Readiness Level of TRL 6. This level is described as: “Technology demonstrated in relevant environment”.
