I made the pulser pump over 20 years ago and it went into wikipedia about a year ago. People have not been interested in making one because you need to dig a 2 or 3 meter hole beside a stream or river and no prior figures are available to help them see what output might be. Eileen on youtube suggested that I try to make a "nano" version instead with small bore plastic tubing and that maybe people would be more interested if the digging component was reduced or eliminated. I couldn't make a nano because I no longer live by a stream but I could test other parts of the nano. So I did a mini airlift pump with about 1 psi or less of air pressure pumping water. (So an airlift pump with about 2.5 ft submergence. Surprisingly it worked pretty good! First attempt I pumped to 13 ft. Of course that is just one component but the result is hopeful. The pulser pump nano model only needs a 3 ft deep pool and a pipe 3.5 inch dia or 4 inch dia dilivering water down close to the bottom of the pool. Air from the pool would then be piped to a bundle of tubes to produce meaningful amounts of water pumping. This pump would have no moving parts of course and could be stacked in series to get greater height. The highest I have pumped with it is 18 ft with 2.5 ft submergence. I don't know how high it can go if really pushed but probably not going so high and pumping in series is the way to go. I think it has potential for pumping water from deep wells in poor places too.
Video is at Pulser pump Nano If you have a stream with a pool in it or if you have a swimming pool and sump pump, you could probably set up a pulser pump nano experiment in a day or less.
And it would be a world's first! The video is a whole year old now and nobody has done it yet. (Don't know why!)
My original pulser pump video has nearly 680,000 views. If you make a nano and lots of people can copy your work, 680,000 views would be chickenfeed!
