The Renewable Resource of Urine Powered Electronics

Urine is rich in minerals and it is believed that this resource will be able to be harnessed and extracted efficiently and cost effectively at some point in the future to produce electrical energy. At the Bristol Robotics Laboratory in the U.K., urine is being studied as a potential energy resource for residential use within the near future (e.g. used to charge a smartphone etc.). Charging a smartphone with urine requires battery like fuel cells with Professor Ioannis Leropoulos (pronounced “yan-iss lee-raw-po-lis”) having developed a system capable of meeting this requirement. The application itself is referred to as “microbial fuel cell” technology, a system which leverages live bacteria to generate electrical current. Urine contains carbon, phosphorus, potassium, sulphur, magnesium, and creatinine, all elements which microbes require to continue living and growing which is why this technology functions as it does. The microbial fuel cell’s central tube is porous ceramic, allowing urine to permeate the tube and microbes to colonize it. As the elements of urine are consumed, electrons generated by the microbes are picked up by the cells of opposing wire coils, creating a battery. Not just any microbe will suffice however, as specific microbes are required for this process to be effective. To source the correct microbes, scientists leverage a plethora of microbes available within the natural environment (e.g. lake, pond, river sediment etc.). Each fuel cell produces 1.5 volts of electrical current, and when linked together in series, output can be increased to a level which is useful for daily activities. The system is able to be scaled so that it can be built into future homes, allowing for individuals and families to recycle urine as a means of generating electrical energy. Leropoulos’ work has been funded by the Bill & Melinda Gates Foundation as well as by the European Commission among others and is close to becoming commercially available as of 2020. For this system to benefit users, separate urinals would be installed but with redirected plumbing to funnel urine away from becoming mixed with common sewage and into a collection container, providing an on demand resource which can be utilized when needed

The Japanese Shinto Faith

The Japanese Shinto religion translates to mean “way of the gods” in Japanese and primarily focuses upon ancestors and nature, with practitioners believing that every aspect of the universe has a deity (e.g. rivers have a god, mountains have a god, soil has a god etc.) with ancestors believed to have created the world for the current generation living within it. Japanese architecture is an excellent example of Shintoism as Shinto shrines are left in a minimalist state of color and simplicity, unlike contemporary Chinese architecture which is highly colorful and decorative. Shinto shrines never depict imagery of deities as the wood of the architecture itself is representative of nature, and from that simplicity and minimalism. This is also because it is believed that so many gods exist within nature that it would be foolish to only highlight a few in particular. Practitioners of Shinto observe festivals and holidays but no particular day of prayer, unlike monotheistic religions (e.g. Sunday for Christianity, Friday for Islam and Judaism etc.). There is no mainstay scripture of morality or ethical system attached to Shintoism. In Shintoism, old shrines are dismantled and moved for new shrines to be erected every 20 years. The 3 main elements of Shintoism are the mirror, precious stones, and wood

The First Personal Computer and its Ramifications Upon Technology

 

The Altair 8800 from Micro Instrumentation Telemetry Systems is considered to be the first personal computer, although ironically, the system itself did nothing as software had yet to be invented. Steve Jobs and Steve Wozniak used the Altair 8800 as the basis for the Apple I, the first ever Apple product. Additionally, Bill Gates and his team wrote Basic for the Altair 8800 and created Microsoft from that programming language

Civilizations Mastery of Metal By Manipulating Fire

The more carbon rich a fuel is, the more heat it produces. Typical wood fires burn at 700 degrees Celsius, however 6000 years ago, ancient people discovered the adaptation of burning wood in a low oxygen environment, only partially burning, but in doing so creating a much purer carbon rich fuel; charcoal. Charcoal can burn at temperatures upwards of 1100 degrees Celsius, hot enough to melt ore out of rock. The mastering of metal produced tools, finance, and weaponry, forever changing the evolutionary story of human beings. By the Middle Ages, the production of charcoal for metal smelting and metal work was a major industry

 

The Person Who Invented the Internet

Tim Berners-Lee created the internet. Berners-Lee is the son of mathematicians, his mother and father part of a team who programmed the worlds first commercial stored program computer, the Manchester University Mark 1. Berners-Lee developed the original concept for the internet as a young boy, after discussing how machines might one day possess artificial intelligence with his father who was reading a book upon the human brain. Berners-Lee realized that if information could be linked, knowledge which would not normally be associated together, it would become much more useful. Ted Nelson helped expand upon Berners-Lee’s invention by developing the concept of hypertext, a method of digitally linking from one section to another. The development of the internet during the 1960’s became user friendly during the 1990’s as it became increasingly available to the public. Berners-Lee was able to take something which was too complicated for most people to use, and create a system which made it user friendly. Incompatibility between computers had been a thorn in the side of technology for years as specialized cables were needed to ensure computers could communicate with one another. Berners-Lee had the brilliant idea to create a centralized block which all cables would feed into so that one central unit could be used for every computer in the world to communicate. Berners-Lee furthered this idea by designing the concept of anything being linked to anything. A single global information space would be birthed as a direct result of this, a system with common rules, which would be accessible to everyone, that effectively provided as close as possible to no rules at all; a decentralized system. This arrangement would allow a new person to use the internet without having to ask anyone else. Anyone, anywhere, could now build a server and put anything upon it. Berners-Lee decided to name his creation the “World Wide Web” because he thought of it as a global network. Berners-Lee took his intellectual property and provided it to the public free of charge, despite having many commercial offers. Berners-Lee felt that the idea would not become the largest and greatest invention of humanity had it not been free, democratized, and decentralized. The fact that anybody could access the internet and anybody could put content onto it, made the internet massively popular early on and grew at a rate of 10x year upon year. Berners-Lee also created the World Wide Web Consortion, an institution which was designed to help the World Wide Web to develop and grow

The Person Who Invented Ecommerce

Michael Aldrich was an English inventor, innovator and entrepreneur who in 1979, invented the concept of ecommerce, enabling online transaction processing between consumers and businesses. Aldrich achieved this feat by connecting a modified television set to a transaction processing computer which could process purchases in real time via dedicated telephone line. This system entitled “Videotex” had a simple menu driven, human to computer interface, which predated the internet by more than a decade. In 1980, Aldrich invented the Teleputer, a multipurpose home information and entertainment centre which was a combination of the personal computer, television, and telecom networking technologies. Aldrich created the Teleputer using a modified 14” color television which was connected to a plinth containing a Zilog Z80 microprocessor running a modified version of the CP/M operating system and a chip set containing a modem, character generator and auto-dialler. The Teleputer operated as a stand alone, color, personal computer during an era when computer screens were primarily monochromatic. The Teleputer contained software and networking capabilities using dial up or leased telephone lines. The Teleputer system itself included 2 floppy discs, each with 360 kilobytes of memory, later upgraded to a 20 megabyte harddrive, a keyboard, and a printer

The Reason Aritifical Intelligence Differs From Traditional Software

Recently, many of the improvements made within the artificial intelligence sector have been due to the technology of “deep learning” which is also referred to as an “artificial neural network”. Traditional software is not intuitive as it simply follows a set of instructions predetermined by a programmer. If the software runs into a new problem which it has no answer prewritten for, it crashes. Deep learning is different as software can now write its own instructions instead of reading the instruction(s) of a programmer. Currently, as of 2021, deep learning is the equivalent of an all powerful, dim witted genie as it has the ability to evaluate the pixels of a photograph of a bottle of water, and can recognize with astonishing accuracy photographs of other water bottles, however it has no idea what the concept of water or the water bottle itself is, what the end user does to drink from the water bottle, what the end user needs the water for etc. This differs in human beings however as humans learn from a sample size of one, and are able to surmise the purpose of water and everything else which is relevant from witnessing it being used upon a single occasion

Rapid Advancements Within Computer Technologies Allowing for the Reduction of Cost and Increase of Performance

In 1985, the worlds most powerful computer was the Cray-2 which cost $35,000,000 ($35 million), and could not see, hear, or speak with its environment. Today, smartphones process data 10x faster and cost less than $1000.00, with the ability to see, hear, and interact with the end user (e.g Apple’s Siri, Microsoft’s Cortana, Samsung’s Bixby etc.). In 1956, the International Business Machines Corporation’s best hard drive weighed 2000 lbs., was 5 megabytes in size, and cost $3000.00 per month which equates to $28,000 as of 2019 when accounting for inflation. In 2019, most solid state Universal Serial Bus drives possess 200x as much storage at a minimum and cost less than $5.00

The Baptistère de Saint Louis and its Significance to European Culture

The Baptistère de Saint Louis was created by Malmuk craftspeople to be used as a luxury bowl to hold holy water during christenings, in fact King Louis XIII used the same object during his christening as an infant. Despite being created by Islamic craftspeople and depicting graphic violence of decapitation and limb severance, the Baptistère de Saint Louis was used for hundreds of years, seemingly without conflict between Islamic and Christian traditions and viewpoints. The object itself is a basin of metal and copper alloy which is inlayed with silver and was crafted in Syria or Egypt during the mid 14th century

 

Technology Provided by the Iron Age

Iron was favored over bronze throughout history because it could be formed into thin and detailed structures which could not be achieved when casting bronze. This is important because it meant that iron blades could be worked and therefore sharpened to a much more refined degree than bronze which was brittle. Iron is also more readily found, a metal which could be found locally around the world and did not depend upon an immense, trading network. By 400 B.C., iron tools and iron objects became ubiquitous throughout various civilizations with the effects of this new technology felt upon the cutting edge of agricultural technology. Iron is more practical than bronze as bronze needs to be melted down and recast if broken in opposition to iron which could be taken to a fire, hit with a hard object, and repaired to the point at which it becomes functional once again. These aspects helped iron to gain favor worldwide as the metal of choice for building and advancing society. As the Iron Age progressed, knowledge about where iron deposits are found became better understood with more and more iron becoming available upon the open market. This is important because the more readily available a particular type of artifact is, the younger the item typically presents as. As time progressed, iron became akin to plastic of the modern day, being cost effective and readily available to manufacture virtually anywhere. Iron tipped wooden plows allowed for more difficult soils to be farmed, which meant that more land could be cultivated making iron truly an agricultural and commercial revolution in the ancient world. Despite lasting for a period of 1000 years, the Bronze Age was quickly replaced with the more effective and efficient Iron Age. The issue of total replacement is complicated as bronze was not only used for tool making, it also helped to create an elite class and was used for spiritual and ceremonial objects as well as visual displays of prestige and wealth. Iron tools several hundred years later, failed to achieve the same intrinsic value within society that bronze once had as it was less rare and precious and therefore less valuable. Iron tools however were highly practical unlike their bronze counterparts, a feature which plagued agriculture and society as a whole
