Hi like I said I'm new here and I've had a lifelong interest in the concept of perpetual motion and over unity (getting more energy from a system then you put in)
First, let me preface this by saying I am not trying to hijack this forum into a debate about perpetual motion so please don't start a fight or ask a bunch of questions which I'd be stupid to answer without a patent.
Due to my interest in perpetual motion, over the last few years I've been researching and experimenting with herons fountains, and other liquid transfer systems. After quite a bit of trial and error I'm convinced I've discovered something and need a little bit of help in trying to build the next prototype
One, I'm having difficulty selecting a turbine style as most of the small generator units I have found were ADS from Amazon Temu or eBay, and they barely contained any information about efficiency, or effective RPM range, plus they don't seem like the most effective designs
Any recommendations for a source with more specialized options preferably retaining the relatively small price range
Two, the information I've turned up on brushed DC motors versus AC motors with a DC rectifier has been confusing due to lack of specifics or claims about the efficiency ranges that seem to conflict
Is one outright better than the other in terms of power generation or is this a case of both operating better in different circumstances under load, and if so which circumstances.
Three, it is my understanding that different turbine styles are supposed to have different effective head ranges. Obviously I'd love to get the most efficient option for my circumstance, which is a bit unorthodox. Right now I'm imagining moving roughly five gallons back and forth through a 3-in pipe every 3 seconds at a constant head height of 4 ft (I know it doesn't make sense to you but please just go with it).
Is there any style of turbine that would be more efficient than 53% under those sort of circumstances? Preferably something saltwater resistant.
Four, I have the option of installing the turbine in an area of the system which would be in constant motion. This raises a few questions because the most efficient styles of turbines are impulse style which aren't supposed to function well under low head conditions.
Is it possible to scale down a pelton wheel or Torgo wheel efficiently, how much would it be affected by different angles of the axis versus slight variations in the head height
Thank you for reading any help would be greatly appreciated.
