Rain Water Harvesting Structure

There is heavy rainfall in Konkan region; however, water run away on the slopes and very little water (around 18%) is left for the use. Hence, people face severe scarcity of water in summer season.

Six houses are constructed around the sides of the hexagonal water tank. When the rain falls on the roof of the houses, it runs away on the roof and gets deposited in the tank.

The capacity of water tank is 1.2lakh liters. Considering the per capita consumption of 25 lit/day, water stored in the tank will be enough for six families for four months of summer season.

Rain Water Harvesting Structure

A Pedal Powered generator provides a method of generating electricity by means of a modified bicycle for producing electricity by means of a Direct Current (DC) generator that is connected by a chain to the flywheel.

The energy generated by the DC generator can be stored in various types of dry/lead-acid batteries. Also, energy that is stored within the battery can be utilized as DC current for use in DC appliances and by using inverter can be use to run alternating Current (AC) appliances.

The unit can generate 100W power by peddling 1 hr @40-50 rpm. It is enough to light two CFL lamps (10W) for five hours.
