This article examines the medieval (Islamic) cities in India from an environmental and technological perspective. The main objectives of this article are (a) to identify and evaluate characteristic features of the cities that were closely linked with the natural environment, (b) to examine the environmental conservation measures, sustainable practices and eco-friendly technologies adopted in these cities, (c) to assess the environmental impact of these cities and (d) to explore those eco-friendly measures and technologies that are relevant even at present. This is a first of its kind review of the Islamic cities in India that flourished from the thirteenth to eighteenth century. Some of the important findings are the following: (a) water had a dominant role in the establishment of these cities, (b) gardens, canals, water-harvesting structures and sanitation were important characteristics of these cities that were profoundly integrated with the natural environment, (c) despite numerous environmental conservation measures adopted, several of these cities declined or were abandoned ironically due to environmental factors and (4) in response to natural environment, some exemplary eco-friendly technologies were introduced, particularly the karez technology for water-supply, which is worth considering to make contemporary Indian cities ecologically sustainable.

Near Future

This article looks at some comparative statistics on the development and use of electric vehicles (hereinafter referred to as EM) as an example of sales and future sales forecasts for EM in countries that focus on environmental conservation. Examples of financial investments already underway and to be made in the near future by the largest automakers in the development and distribution of EM in the world are given. Steps are taken to improve the environmental situation in countries (for example, the prohibition of entry into the city center), the scientific and applied problem of improving the energy efficiency and environmental safety of the operation of wheeled vehicles (hereinafter referred to as the CTE). The basic and more widespread schemes of conversion of the internal combustion engine car (hereinafter -ICE) to the electric motor car (by replacing the gasoline or diesel electric motor), as well as the main requirements that must be observed for the safe use and operation of the electric vehicle. The problem is solved by justifying the feasibility of re-equipment of the KTZ by replacing the internal combustion engine with an electric motor. On the basis of the statistics collected by the State Automobile Transit Research Institute on the number of issued conclusions of scientific and technical expertise regarding the approval of the possibility of conversion of a car with an internal combustion engine (gasoline or diesel) to a car with an electric motor (electric vehicle), the conclusions on the feasibility of such conclusion were made. Keywords: electricvehicles, ecological safety, electricmotor, statistics provided, car, vehicle by replacing.
