at present due to di
culties in water pumping. All these can
be made productive for wealth creation via food production by
the installation of solar-powered water-pumping systems. Water-
pumping systems can have a wide range of power requirements
depending on their size. They can also be expanded as the water
demand grows with time. This is a practical example of technology
transfer andfood production for the modern society.
10.8 Solar Power Applications on Roads
There are many opportunities for the development of our future
roads using solar energy. The development of a road network is
crucial to the economic development of any country. Road signage,
tra
c lights, street lighting, and future solar-powered electric car
parks are a few examples (Fig. 10.9). Solar-powered street lighting
will improve security on roads by removing the need for electric
cables and use of electricity from the national grid. In all tra
c
lights, high-power-consuming filament bulbs should be replaced
