Anyway, low pressure tromps combined with low pressure airlift pumps
have NOT yet been yet been described by science. There are
interactions between the tromp and airlift sections which make the
whole system quite a deal more complex to describe than the 2 devices
working seperately.

Then do the work, or pay someone to do it.
Whinging doesn't help.

I have no use for such a device.
