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

1. 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.

2. The heated gas increase in pressure and pushes power piston to farthest limit of power stroke

3. Displacer piston now moves, shunting gas to cool end of cylinder

4. Cooled gas is now compressible by the flywheel momentum. This takes less energy, since when it is cooled its pressure drops.

2. INNOVATING A LOWER COST ALTERNATIVE
