Abstract
Hot cites are often referred to hot countries. Typical areas include Southwest Asia, Africa and some near the equator. Hot cities generally have difficult conditions to grow into cities. However, there are some cities that have been exported and developed with the choice of resources, and others that have not been developed due to lack of resources. However, most countries in these countries are located between 0 and 30 degrees latitude, which increases solar radiation, so they can secure more solar energy than other regions and produce enough energy to replace fossil fuels. It is also expected to create city that conforms to UNSDGs by producing renewable energy called solar energy. Developed cities in Hot City are to collect solar heat by attaching a transparent solar panel (TSP), a laminate with transparent solar panels, inside a building formed by glass. By using TSP, it has supplemented problems such as oxygen and humidity, shortening of life expectancy due to organic materials, aesthetic problems, and inefficient spatial layout that were present in current solar panels. In addition, the energy efficiency generated by TSP's power generation technology could help provide a smoother supply of electricity to homes and businesses, as studies have shown that coating the entire glass surface of the United States, 5 ~ 7 billion square meters, produces an additional 100 gigawatt power. In addition, surplus energy after use can be utilized by introducing a system called swytch token. Swytch tokens will have a positive effect on increasing the number of people who want to produce and consume them with a system that rewards those who produce renewable energy with economic value. To provide economic rewards, there is a Proof Of Production (POP) system that proves that energy is produced, and blockchain, a distributed data technology that stores data in blocks and links it to chains, replicating it to numerous computers at the same time. Blockchain use allows users to disclose transaction details without storing them on a centralized server, which reduces falsification of data, increases transparency, and allows them to pay tokens to computers, store and use them. It will be presented as an example of a leading advanced city that can incorporate blockchain and virtual currency into cities. In the case of developing cities, however, not only are there not enough skyscrapers to use TSP technology, but also lack housing supplies, making it difficult to supply and demand energy. To compensate for this, 3D printing is used to create dwellings and attach TSPs. New story and ICON, which make housing used by 3D printing in the U.S.A, unveiled prototype housing, which is built based on international architectural law and lasts longer than standard concrete bricks, and boasts excellent economic feasibility with a 24-hour price of $10,000. Already in the case of Haiti, Bolivia, El Salvador and Mexico, more than 800 homes are known to have collaborated with the community, using local labor and materials without supplying materials abroad. Based on these examples, organizations such as international organizations and NGOs can establish 3D printing houses and link them to 3D printing houses using TSP technology, not only the housing problems of poor and refugees but also the culture, characteristics and traditions of each community can be specialized. Most of all, as the price of solar-related technology is falling, it will be a little more common technology in the future. Lastly, rather than making a city with fossil fuels seeking profit, we should create an advanced city that uses future innovative technologies such as next-generation solar energy development and 3D printing to convey new hope to the poor.
