In late 2007 I published my installation for a sea kayak electric bilge pump (on QSKC website_ it has been recently removed by the current webmaster).
I published a variation of that installation on this blog in 2009.
The article has attracted a tremendous amount of interest and I have seen links to my article appear on many websites around the world.
USA, British and German readers are particularly interested in the set up.
Recently I have found a manufacturer that appears to offer the same set up commercially.
There are no details (images or drawings) of the system but it lists the components that are the same as my documented items.
The video on their website seems to replicate the identical set up as mine.
However what intrigued me is the mention of a magnetic switch for the activation of the pump (Bluewater website: "Sealed switch, waterproof, dustproof, operated by a sliding magnet that runs on your deck bunge cord")
To my knowledge, I was the first to publish the idea of the switch, even though it is not my invention.
I am not aware of any other publication showing the magnetic switch assembly.
I do know that manufacturers occasionally scan my blog for ideas and some actually use my findings on their products.
There is nothing wrong with that, or I would keep my tinkering ideas to myself.
What makes me a bit dubious is the fact that Bluewater claims a pending patent to the system.
Bluewater makes no mention of the alleged patent number (most manufacturer don’t divulge that) but I have not been able to find any documentation of such patent in my searches.
There are a couple of scenarios: Bluewater could have applied for a patent that is not directly related to the bilge pump system that I have documented or they are just bluffing to scare competition away.
Bluewater has not replied to my queries of patent application date, and probably won’t :-)
If Bluewater has applied for a patent of the existing system, it will not be valid.
The electric bilge pump system has been used for some time now (documented on several websites) and the magnetic switch documentation is not recent (Feb 2008)
Gnarlydog News ideas are published for the benefit of the private public and not for the monopolization from the industry.
I want to keep sharing my findings with fellow adventurers that might benefit from my projects.
