Has anyone heard from Glenn Martinez from Hawaii? I would like to get in touch as I bought a manual of him years ago and my external drive died which had the file on it (i know should have had a cloud backup).
I have tried the email addresses I had but they bounce…
I tried to get in touch about a year and a half ago. Didn’t hear back. Loved his air lift though. Did it for a farm here in Jordan and lifted water about 3m. Was a fun experiment. If we still had the farm we would have probably used it as dragon tails for a separate aeration source in the hot summer months.
From the article:
“We replaced one 200-watt submersible pump with an 80-watt air compressor to run an airlift.”
One has to be careful not to compare nominal power rating with actual used wattage. A 200W pump is not pulling 200W all the time.
Would really love to see a direct comparison between these two types of pumps.
Water on a higher level has potential energy. So In the end probably an energy efficiency rating of electrical energy required to produce a defined amount of potential energy would be helpful. Of course tabled with different head heights.
