is an amateur science forum in the Netherlands. I posted a call for
them to try the pulser pump a couple of months ago and sure enough the
first few replys were the usual sarcastic insulting jokes.
But people are now making models (admittedly piecemeal ones (but big)
so far) and starting to ask questions too! So, perhaps if you need
independent confirmation that it works, that is probably the best
place to go at the moment! It IS a dutch forum but they have been kind
enough to post some in english for me. Bring your babblefish or other
translator, I guess.
Take care
