Nanotechnology and its applications are increasingly present in our daily lives. However, until recently they were considered science fiction.
Medicine, engineering, computer science, mechanics, physics or chemistry are just some of the disciplines that are already benefiting or will soon benefit from the possibilities offered by nanotechnology.
The possibilities offered are multiple and there are already on the market products applied in medicine and surgery, computer science, food, building construction, cosmetics, textile fabrics and systems for water purification and desalination.
For example, NASA relies on nanotechnology to advance its space challenges through new, more powerful computing technology, new sensors, new materials, and miniaturization. Nanotechnology will be the basis of the entire manufacturing industry.
Nanotechnology Applied In Water
According to a World Bank report, water is one of the major concerns of the United Nations. Almost half of the world’s population does not have access to a basic health system, and almost 1.5 billion people do not have access to clean and safe water.
Of all the water consumed in the world, 67% is used for agriculture and 19% for the industry. Domestic use accounts for less than 9%. Molecular manufacturing could replace a large percentage of industrial production. Much of the agriculture could be moved to greenhouses.
Domestic water can be treated and recycled. Taking these steps could reduce water consumption by at least 50% and probably by as much as 90%.
Water-related diseases account for the deaths of thousands, perhaps tens of thousands of children every day. All this could be prevented with basic technology, a technology that can be manufactured very cheaply if the factories are cheap and portable.
Nanotechnology Applied In Solar Energy
At present, the largest source of energy is derived from the burning of coal-containing fuels. This process is often inefficient, non-renewable and also has adverse effects on the environment.
Solar energy would be a viable alternative to energy in many parts of the world. This will happen, if the cost of its production and the land needed to generate it were sufficiently economic and storage systems to be sufficiently effective.
The generation of solar electricity depends on the photovoltaic conversion or the concentration of direct sunlight. Photovoltaic conversion works on cloudy days with lower efficiency while the direct sunlight concentration system can be achieved without semiconductors.
In both cases, not much material is required, and mechanical designs can be simple and relatively easy to maintain. Following the trend that was enhanced by genetic engineering, from corporate control from seed to product in the supermarket, nanotechnology agriculture would even control the atoms that make up those products.
