Concept
Using steam, the sun, pressure, and solar panels, pump, battery

1. Sun heats the water
2. Pressure adjustment allows for faster boiling
pv=nrt
3. Solar panel changes port sizes to adjust pressure
4. pump circulates the water via solar
5. Water could be a closed system or some stream source, if stream then could harness energy there also
6. Steam rises, water condenses,, cycle repeats
7. Ram pump can create constant flow from stream
8. Wind power could also charge a battery

Sun is outside the circuit
Stream is outside the circuit
System has inputs outside itself
