I made some short video clips of a pulser pump model. They are in .mov format (apple quicktime) and you will find them in the files section in the group home....
This might be explained in a FAQ somewhere, but has anyone done any studies of optimum ratio of pipe diameter to lift height, or to depth, or ??? I only...
Hi, Daniel, I have seen figures in engineering manuals about airlift pumps and I honestly feel that they are not relevant. Industrial airlift pumps use ...
Hi, Brian. I am thinking of building a pump, but it'll have to be a small demonstration model at present since I don't live anywhere near a stream or other...
Geyser pump Masao Kondo has applied for a US patent for a new type of airlift pump called a geyser pump. He has also made parts which could be used to convert...
Just a note that my brother sent 2 video clips of a small pulser pump back in Ireland. They are short ones without sound. They show the 6 inch pump stripped of...
I will be blasting Burts little offering. But the facination with ram pumps is widespread. They are useful no doubt but are certainly not the cureall that so...
These videos show pumping to about 4 ft with the small deeper pulser pump providing the power. (The earlier videos show the pump that uses 6 inch pipes just...
Very much like the old Ram Pump only with no moving parts. It does need a lot of water though and the limitations do need to be understood in terms of head and...
I repeat, It isnt like a ram pump! GRRRR. Totally different working principle. I will help you with the design if you have a suitable site. Sites with low head...
I am indebted to Gordon Cougar for the link below. Aparently, Albert Einstein was interested in airlift to such a degree that he had international patents...
My yahoo account has been bombarded with spam including huge attachments of late. Apologys if any of you tried vainly to contact me. Try the same username at...
Well, since the last message, there hasnīt been anything concrete new. A New Zealand teacher has emailed saying that he will make a syphon pump with his...
http://www.wetenschapsforum.nl/viewtopic.php?p=26222#26222 is an amateur science forum in the Netherlands. I posted a call for them to try the pulser pump a...
Jaanus Jogi sent me this link to a back issue of mother earth news and their trompe explaination (It is great to find tromp info in a reputable magazine.(So...
The spirit of amateur science died and moved to the Asia! A young man in the Philippines is currently doing a pulser pump project in his physics course. I...
Over the last couple of years, I get ocasional emails about pulser pumps for different locations, I give out info, and wait for the pics of the pumps or pump...
I got a very nice message from a group member(I dont know if I have permission to post it). Rest assured, I will still push people and institutes to do...
Thank you for keeping me still on your mailing list. One thing I know is Big Business sponsored most of those successful men - politicians and artists to get...
Hi, I'm working on designing efficient heat engines which can operate off the daily temperature fluctuation. My latest design uses a trompe connected to a...
List: The "Trompe/Bubble pump air compressor heat engine" is a figment of the imagination and cannot work at all in any way as proposed and "explained." Ask...
nice to see some post in this group i remember seeing a mention about such a pump being used to ventilate a mine on a very very large scale .. using a pulser...
... Your are refering to something like the Ragged Chutes Hydraulic Air Compressor on the Montreal River in Canada. It is described in some detail at: ...
... It is a design project, not a working machine. Do you doubt it would work given a larger deltaT? (just curious about where your objections lie). ... This...
Just wondering if you have factored in energy losses in the tromp and bubble pump due to turbelence? And the different densitys of the hot and cold water and...
Mainly I was trying to figure out ahead of time if it would be worth building one and seeing if it works. Turbulent flow needs to be avoided by using large...
