A common water saving tip found in various water saving guides is - ‘Use a bucket to collect water while waiting for the shower to get hot.’ A new invention called the Cullector makes such methods redundant.
Developed by Peter Cullin of Cullin Innovation, the Cullector water saving device can be easily retro-fitted onto the existing shower outlet against the wall. The initial volume of cold water that would normally be lost to the drain is collected and gradually reintroduced into the shower stream once the stream warms to the desired temperature.
The Cullector water saving device uses principles of fluid dynamics to use of every last water drop. The water pressure of the shower outlet is the only power the device needs. The Cullector water saving device was featured on ABC’s The New Inventors in April. The prototype presented on TV was fully produced by Formero. It was chosen as best invention and also picked up the public vote.
“Formero were very understanding and supportive in my first tentative steps into the building process of the prototype, including issues such as scaling, file format, resolution and choosing the best materials for building a series of prototypes to confirm functional geometry,” says Peter Cullin.
The final commercial prototype mechanism was CNC milled from stainless steel. “When the mechanism arrived I was blown away by the quality of the finish including the imbedded text and the accuracy of all ten components. The mechanism assembled correctly the first time and was tested to predict flow rates,” Cullin adds.
With the help of Formero , Cullin Innovation has a high quality fully functional commercial prototype to demonstrate to potential licensees. The Cullector water saving device is soon to be commercially available as an off-the-shelf product.
