Here is some interesting info for you.  Years ago I had a guy come up to me in San Antonio and wanted to know if I could use a pump to clean out his sludge tank at a factory.  In the past they would have to shut down the factory for three weeks and clean the tank by hand.
 
I went out and studied it, I then called Randy Everson of Wester Pumps (the brand) and George Brock (owner of Hercules and Western) with my idea.  I said if we put a seal tight lid on the hopper and had a discharge hose off the hopper could we put the pump in reverse and suck out this sludge.  We talked several times and after a few expierments the prototype was ready.  Monty Everson came over from Houston with the modified pump.  Not only did we suck out the sludge and clean the tank in one day we pumped the sludge thru an irrigation hose 2000 feet to a holding pond.  This was how Sludge Busters was born.  From that point they went on and built a fleet of sludge pumps and eventually sold the idea and patent to schwing.  I got nothing.
 
Fast forward a year and another guy came up and wanted to know if we could frac shallow oil wells with a concrete pump.  Once again I talked with Randy and George and we developed a pump that would put enough pressure on the well head to frac the well.  We did over 200 wells before the oil industry went belly up back then.  We charged only $400.00 a well and could do two a day,  Haliburton, Western, and others were charging up to $20,000 a well.  Needless to say they were not happy.  Tried to pass this idea on again and no one was interested.
 
Fast forward again to the Exxon Spill.  My brother and I put together several proto type special suction devices to put on the end of a boom or hose and together with a modified sludge pump/concrete pump we did our own oil spill on a pond and cleaned it up.  We videotaped our idea and sent it off to a lot of companies.  Once again our special attachements would suck up mostly oil from the surface and little water which could be separated out in a barge.  Our idea was fully mapped out and contained all the information need to have on hand the modifications needed to make every pump an oil spill recovery pump.  We envisioned all fleets having a contract and special training with the EPA to be available on short notice to respond.  No one responded. 
 
Fast forward to Katrina and the Flood - I showed on paper how much water a large cell concrete pump in reverse could move.  Not only would a concrete pump pump the water it would not be plugged up with mud or rocks or beer cans or anthing else floating.  Pumps that were not being used to pump concrete could quickly be modified to pump water which would have greatly accelerated the clean up in New Orleans.  The main problem they had after the storm was no power to their normal pumps and little water pumps you see on construction sites were worthless.  Yet there sat fleets of pumps which could have helped a lot.  Do the math and see how much water a 100 pumps could move in an hour.  Sent the idea to a lot of people both private and government and not a response.
 
I have no problem if you want to put this on the site - Everyone should know there is an answer to every problem.  If you (people in general) don't like the way something is done and always complain, then stop and figure out a better way.

Here is another idea from the past you can throw out to the readers of your web site - maybe one of them will make a go of it.
 
Years ago when we were first using fly ash in concrete I did some research on what fly ash was.  To make a long story short it is the by product of coal.  Under a microscope it looks like glass beads.  It cannot be burned since it has already been burned.
 
I started to mix up fly ash with paints and primers with the idea of coming up with a cheap non chemical fire resistant paint that would not emit toxic fumes while burning.  After a lot of trys I was able to do just that.  Problem was I could not get any body interested.  Fast forward a few years.  While doing the expirements I used a lot of wood which was behind my house.  Years later when I went o clean all of it up I found something very interesting.  Wood that was completely treated had no insects.  Wood that was not treated was just dust and almost completely eaten up,  Wood that was treated on one side was like knew the other side was eated away by bugs and termites.  Seemed that bugs did not like eating thru glass.
 
Here is an idea that makes wood fireproof and bug proof and I could get no one interested.

Perhaps you should have focused on charging for your good ideas. Others are charging $20,000 and you charge $400. The story of the pumper in one sentence.

Mike you had some very good idea's thats what it takes to be in the pumping business being able to build easyer way good job.

We just had a flood here in Tenn the first of may I thought about doing that very same thing help the fire dept pump water in our subdivisions,olny thing I didn't have all the reducers so I could hook up smaller hose.

Mike you were always full of good ideas.
