the project aimed at designing a low cost less space consuming solar water heater for bathing purpose only(it heats to bathing hot only).
A thermocouple based solar boiler is deviced & tested for its hotness. it boils water at a lower temperature as low as 45degrees using low pressure boiling technique. this does not require huge panels, its cost is less than 75% of existing designs. the prototype design heats a volume of 22litres upto bathing hot. (the same type of hotness which you feel while holding a car steering of a car which was parked in hot sun.the car temperature will be less though)
