Hi, can you explain a little bit why you are using a hose pump vs. another (piston) pump ?
Hi, I have chosen a peristaltic pump, as it is robust.
Maintenance is simple and the parts are easy to get.
Do you have any doubt?
Your Constructive Criticism is welcome :-)
A Sterling engine is a very good idea. If necessary you can also use is during the night if you make a fire.
Could you give some more information and estimates how much water flows through the pump in one hour. And how does it work exactly?
You could use the water to cool down the Sterling engine -> much more effective than air!
A stirling engine, interesting! What size did you think of for your parabolic reflectors? I believe the choice of your pump also depends on the type of irrigation system you plan to use - any ideas on that?
All the best,
i like the use of the stirling engine but the whole parabolic reflector with the stirling engine already exists and just attaching a pump to it I don't think you would be able to get the size/capacity requirements needed for 1 hectare
A peristaltic pump would require a lot of start-up torque (positive displacement pump). A centrifugal or vane-axial(archimedes screw in a tube) one would take less start-up torque.
SSchrecker informed me that my idea is similar with yours. My uploaded link is as followed
In my work, I use larger plate to form a stirling engine, thus the flowed water can cool the air and the make the temperature difference.
SSchrecker suggested that my idea can be merged with yours. How about your thinking, it depends on you. (You uploaded the idea before than me, so you can make the decision:> )
good design :)
good effort the system can be improved
