New Pedestrianism
New Pedestrianism (NP) is a more pedestrian and ecology-oriented variation of New Urbanism in urban planning theory, founded in 1999 by Michael E. Arth, an American artist, urban/home/landscape designer, futurist, and author. NP addresses the problems associated with New Urbanism and is an attempt to solve various social, health, energy, economic, aesthetic, and environmental problems, with special focus on reducing the role of the automobile.A neighborhood or new town utilizing NP is called a Pedestrian Village. Pedestrian Villages can range from being nearly car-free to having automobile access behind nearly every house and business, but pedestrian lanes are always in front. To a large extent New Urbanism is a revival of traditional street patterns and urban design. New Pedestrianism also respects traditional town design, but seeks to further reduce the negative impact of the automobile, the use of which has increased dramatically since WWII. By eliminating the front street and replacing it with a tree-lined pedestrian lane, emphasis is placed on low-impact alternative travel such as walking and cycling. Pedestrian lanes are usually 12 to 15 feet (5 m) wide, with one smooth side for rolling conveyances such as bicycles, Segways, and skates and the other, narrower, textured side for pedestrians and wheelchairs. Eliminating the automobile street from the front allows for intimate scale plazas, fountains, pocket parks, as well as an unspoiled connection to natural features such as lakes, streams, and forests that may border or be included in a Pedestrian Village. A vast public realm is created that is free from the sight, smell, and sound of automobiles, yet automobiles are still served on a separate network. New Pedestrianism has been proposed for Kisima Kaya, a new town in Kenya, for Tiger Bay Village, FL as a solution to the homeless problem, and for new towns and neighborhoods that can be built anywhere whether as rehabilitation of existing neighborhoods, infill, edge-of-town neighborhoods, or new towns.

LightScribe
LightScribe is an optical disc recording technology that was created by the Hewlett-Packard Company. It uses specially coated recordable CD and DVD media to produce laser-etched labels with text or graphics, as opposed to stick-on labels and printable discs. Although HP is no longer developing the technology, it is still maintained and supported by a number of independent enthusiasts. The LightScribe method uses the laser in a way similar to when plain data are written to the disc; a greyscale image of the label is etched (physically burned) onto the upper side of the disc using a laser. In the beginning, the discs were available only in a sepia color but later became available in many monochromatic colors. The purpose of LightScribe is to allow users to create direct-to-disc labels (as opposed to stick-on labels), using their optical disc writer. Special discs and a compatible disc writer are required. Before or after burning data to the read-side of the disc, the user turns the disc over and inserts it with the label side down. The drive's laser then burns the label side in such a way that an image is produced. (see Thermal printing; LightScribe uses a laser instead of a thermal printing head)

Bluetooth Low Energy Beacon
Bluetooth beacons are hardware transmitters - a class of Bluetooth low energy (LE) devices that broadcast their identifier to nearby portable electronic devices. The technology enables smartphones, tablets and other devices to perform actions when in close proximity to a beacon. Bluetooth beacons use Bluetooth low energy proximity sensing to transmit a universally unique identifier picked up by a compatible app or operating system. The identifier and several bytes sent with it can be used to determine the device's physical location, track customers, or trigger a location-based action on the device such as a check-in on social media or a push notification. One application is distributing messages at a specific Point of Interest, for example a store, a bus stop, a room or a more specific location like a piece of furniture or a vending machine. This is similar to previously used geopush technology based on GPS, but with a much reduced impact on battery life and much extended precision. Another application is an indoor positioning system, which helps smartphones determine their approximate location or context. With the help of a Bluetooth beacon, a smartphone's software can approximately find its relative location to a Bluetooth beacon in a store. Brick and mortar retail stores use the beacons for mobile commerce, offering customers special deals through mobile marketing, and can enable mobile payments through point of sale systems. Bluetooth beacons differ from some other location-based technologies as the broadcasting device (beacon) is only a 1-way transmitter to the receiving smartphone or receiving device, and necessitates a specific app installed on the device to interact with the beacons. This ensures that only the installed app (not the Bluetooth beacon transmitter) can track users, potentially against their will, as they passively walk around the transmitters. Bluetooth beacon transmitters come in a variety of form factors, including small coin cell devices, USB sticks, and generic Bluetooth 4.0 capable USB dongles.

Zero Energy Buildings Concept-Definition Review for Latin America
In recent decades, European countries have developed concepts, definitions, and construction technologies for Zero Energy Building (ZEB) that are effective and correspond to their specific climates. Latin American countries are still trying to find adequate solutions which respond to the local climatic, cultural, social, technical, and economic context. As such, this paper aims to establish the basis of the minimum energy efficiency and the renewable threshold for the definition of ZEB in order to better understand the application in Panama, based on assessing the energy regulations implemented in Panama. To achieve this aim, a review concentrated on the concept-definition and implementation adopted by Latin American countries is presented first before the paper converges into defining a framework for application in Panama. Finally, a case-study-based theoretical framework proposing a ZEB definition for Panama is discussed. The results of this study showed a net primary energy balance, of which the range falls into a plus energy building definition, indicating that all of the cases studied could supply their electricity needs using Photovoltaic generation. All dwellings studied have the potential to become a plus energy building, depending on the available roof surface area. Finally, a strengths, weaknesses, opportunities and threats analysis is presented in order to assess and support the introduction of such a ZEB definition and framework.

Collaborative Learning
Collaborative learning is an exchange of ideas that enables and improves the interaction between two students (student–student) coping with the learning material on a network. When somebody imagine individuals seemingly completely focused on the screens and keyboards of their devices, people most frequently have a preconception that they are using those learning devices by themselves. However, such images of individual learning accompanied by electronic tools frequently do not reflect the hidden reality. In reality, students often use their computers to interact with others, and it is frequently their peers whom they interact with. These ideas arise from learning technology known as collaborative learning. Collaborative learning principles arise from a well-established approach to education, have a specific meaning and are specifically applied in practice.

Field-emission Display
A field-emission display (FED) is a flat panel display technology that uses large-area field electron emission sources to provide electrons that strike colored phosphor to produce a color image. In a general sense, an FED consists of a matrix of cathode ray tubes, each tube producing a single sub-pixel, grouped in threes to form red-green-blue (RGB) pixels. FEDs combine the advantages of CRTs, namely their high contrast levels and very fast response times, with the packaging advantages of LCD and other flat-panel technologies. They also offer the possibility of requiring less power, about half that of an LCD system. Sony was the major proponent of the FED design and put considerable research and development effort into the system during the 2000s, planning mass production in 2009. Sony's FED efforts started winding down in 2009, as LCD became the dominant flat-panel technology. In January 2010, AU Optronics announced that it acquired essential FED assets from Sony and intends to continue development of the technology. (As of 2016), no large-scale commercial FED production has been undertaken. FEDs can also be made transparent. FEDs are closely related to another developing display technology, the surface-conduction electron-emitter display (SED), differing primarily in details of the electron-emission system.

Lithium as an Investment
In 2020, Lithium has been included in the list for Critical global elements critical metal, and will be one of the drivers of the fourth industrial revolution. Lithium company stocks on the worldwide exchanges have rallied from the end of 2020 and through 2021 with many Lithium Explorers/Developers/Producer miners' share prices' rising 1000% to 6000% within 12 months on the ASX: the Australian Securities Stock Exchange. Stocks are expected to continue to rally as a shortfall deficit of Lithium supply world-wide is expected from beginning of 2022. The Battery-grade Lithium deficit is expected to persist to an incredible 2030, as there are not enough mines coming online to supply the demand in EV Batteries & Energy Storage systems to 2030. This makes Lithium a highly lucrative commodity to invest into, the term entered a "Lithium commodities Super-cycle" has been used by industry commentators during 2021 to describe the event, also the term "A Once in a Century" event is occurring in 2021 and will persist till new Energy technologies come online to replace Lithium Batteries, this is not expected till after 2040 as there are no technologies that will be suitable for the diversity of applications for Lithium Energy storage systems. Lithium carbonate prices have made a resurgence from 2019-2020 all time lows, rising some 500% as of 21/11/2021 trading at US$29,000/tonne, Lithium Carbonate/Lithium Hydroxide is a Lithium chemical compound also known as LCE(Lithium Carbonate Equivalent) and is used as a Precursor in the manufacture of Cathode Cells for electric vehicle (EV) batteries. As a result and along with major Governmental new energy policies in 2020, in preparation to the fazing out of fossil fuels & reductions in carbon emissions vehicles & coal power, has kick-started a flurry of renewed investments & Joint Ventures/acquisitions between Miners & Strategic major investor companies throughout the world. Recently the world saw the COP26: Climate Change Summit for Action in Glasgow during November 2021. The agreements signed by all countries involved, has accelerated the action towards renewables adoption & the reforestation among other items & actions. Lithium will play a key & critical role towards the reduction of Carbon emissions, "1.5ToStayAlive" "1.5toSurvive" slogans for maintaining the critical 1.5 degrees & the storage of renewables clean green energy, harnessed from the sustainable wind, solar & hydropower, also tidal. Also big on the COP26 agenda was the fazing out of coal all-together. Lithium is an essential mineral that goes into the manufacture of electric batteries (Lithium-ion battery: portable electronics, EV and renewable ESS). Lithium supply is expected to fall short of the demand for this metal by 2022. Demand/supply discrepancy "the Great divide" ratio has been witnessed in July 2021 when the BMX Spot price Platform went live and the price for Lithium Spodumene Concentrate 6% (SC6) reached a record price of US$1,400/tonne, rising from its lowest of US$395/tonne in September 2020. Today SC6 price(21 November 2021) trades at US$2,550/tonne, Australia's Pilbara Minerals, the company that developed the BMX Spot Sales Platform are commended for this initiative with Ken Brinson, CEO, saying the price for Spodumene Concentrate 6% is now transparent to the market making it a fairer playing field for the Miners and the Chemical Converter Customers. Governments are adopting the New Energy Lithium Technology rapidly as the pressure to meet the Paris Agreement CO2 Carbon emissions reductions. Major Car Manufacturers are planning on a large line-up of new Electric Vehicles by 2025, in what's called the "EV Revolution". The growing adoption of electric vehicles (EVs) is driving the increasing demand for lithium, significant amounts of lithium supply will need to be brought online to meet this demand growth to 2030 and beyond. The situation is seen as critical as the world depends on Lithium. A new technology in the extraction of Lithium from Geothermal brine, the extraction method is called DLE-Direct Lithium Extraction and if/when the technology succeeds in "scale" it will be celebrated as it will help alleviate the pressure on the tight Lithium supply, the technology is not expected for another 4-5 yrs(2025/26) if not longer. See Start-ups Vulcan Energies(ASX:VUL) & Lilac Solutions(USA) for their efforts in DLE. Pond evaporation extraction Technology is considered old & expected to be obsolete as it conflicts with a world turning towards ESG(Environmental Social & Governance) compliance in mining/extractive practices. Products that reduce carbon emissions, including electric batteries, are globally expected to create a $23 Trillion market over the next decade to 2030. Lithium is considered a superior lightweight metal element for its electrochemical properties as a charge carrier in the electric battery, currently there is no known replacement element to achieve such effective performance for automotive battery applications. According to Volkswagen, in the near future lithium will be one of the most sought-after raw metals on earth. Forecasted EV battery demand growth is driving the need to significantly increase battery production globally. Major battery manufacturers have already committed $175Billion by the start of 2021. Even though a significant amount of capital has already been committed, further investment is expected, to satisfy the forecasted growing supply chain demand of batteries to 2030. There has been a trend already with lithium chemicals compounds producing companies, battery manufacturer companies and even major car manufacturers investing or partnering with raw material suppliers/miners. Large investments are flowing into the lithium supply chain from established majors. Companies with partnerships or joint ventures will be more resilient in the long run. Major car manufacturers' plans to spend over $300 billion are being invested and forecasted over the next 4 (2025) to 10 years (2030) during the adoption of electric vehicles (EV). Automakers’ plans to spend at least $300 billion on EVs are driven largely by environmental concerns and government policy for GHG reduction and supported by rapid technological advances that have improved battery cost, range and charging time. Since 2018, we have seen an accelerated rate of industry spending especially through 2020. Most importantly, with the global push for sustainable and low carbon footprint mining, processing and manufacturing, where will the lithium that is ESG sustainably sourced with a GHG low-carbon footprint come from. Necessary to feed the burgeoning energy storage needs for the growing transport and military sector; electronic consumer requirements; and in particular the domestic & commercial automotive supply chain where investment spending and forecasts are $US400 to $US500 billion . Both the drive to decarbonize and the 4IR depend on critical minerals like lithium. The Fourth Industrial Revolution (4IR or Industry 4.0) has been defined as technological developments in cyber-physical systems such as high capacity connectivity; new human-machine interaction modes such as touch interfaces and virtual reality systems; and improvements in transferring digital instructions to the physical world including robotics and 3D printing (additive manufacturing); the Internet of Things (IoT); “big data” and cloud computing; artificial intelligence-based systems; improvements to and the uptake of Off-Grid / Stand-Alone Renewable Energy Systems: solar, wind, wave, hydroelectric and the Lithium-ion electric batteries (for renewable ESS and EV). Speculation in lithium compounds used as feedstocks for major applications. The main intermediates are lithium hydroxide and lithium carbonate, and these are the commodities that the LME has chosen as the most appropriate to establish reference pricing. Speculators hope to make a viable play on a perceived growth in demand for lithium metal due to the widespread adoption of lithium batteries in emerging technologies. Lithium batteries have become a preferred power source for energy-hungry devices such as cell phones because they are more efficient and scalable than previous-generation nickel-metal hydride batteries thus they are in high demand in support of automobile and electronics manufacturing. Factors that could result in limitations affecting overall lithium supply are seen by some as prescient; with predicted supply chain volatility potentially overpowering other market factors and becoming the primary price driver, essentially resulting in a seller's market and thereby making the metal a profitable investment.
