1. Data-basing existing solar pumps2. Innovating a low cost alternative
Vision:
Values:
Well Dimensions:
64 Submersible pumps from 9 manufacturers
1. Data-basing existing solar pumps
Improved Functionality with criteria input and searching function
Create an interactive database of existing solar powered (DC) submersible water pumps suitable for pumping well water
Location:
Stirling
Engine
The Stirling Engine is a heat engine that converts heat to mechanical work
Sun Collection Method
Mission
:
Current Design
Power piston (dark grey) has compressed the gas, the displacer piston (light grey) has moved so that most of gas is adjacent to the hot heat exchanger.
The heated gas increase in pressure and pushes power piston to farthest limit of power
stroke
Displacer piston now moves, shunting gas to
cool end of cylinderCooled gas is now compressible by the flywheel momentum. This takes less energy, since when it is cooled its pressure drops.
