Number Theory/Irrigation water pumps.


Dear Prof Scott

Is it possible to design and manufacture noiseless irrigation water pumps running on electricity or Gasoline?.


Ads exist for water pumps made by differing organizations.  They are between $150 and  $650.

This site,,
has water pumps that need to be plugged in and water pumps that run off of solar electricity.

Pumps are designed as rotary pumps and vacuum pumps.  Also on this site are water pumps for under $10.  Over on the left side of this page there can be found a way to get to suppliers and manufacturers of such pumps.

It this page as well, they can be seen to look many different ways.

I can answer almost anything that is sent in. If I can't, I'll let you know, but I don't expect that to happen much.


I have known about number theory since the mid 80's. I have answered over 250 questions on Number Theory with this software. Altogether, I have answered over 8,500 questions in mathematics.

You're looking at it ... I've answered over 8,500 quesitons in mathematics right here.

My credentials are an MS in Mathematics at Oregon State in 1986; I received a BS in Mathematics at the same place in 1984.

Awards and Honors
I graduated with honors in Mathematics when getting my BS degree and my MS degree.

Past/Present Clients
I have assisted many students in mathematics at OSU. Perhaps I have assisted one of you're friends in math on a computer somewhere else, but you don't even know... That would be late last night, perhaps with thousands of miles between us ... Then again, if you're in Washington, so am I ...
