Throughout my 34 year corporate career in marketing and sales, I learned to always keep an eye out for non-existent products that might fill a niche which would both enhance the needs of people and be profitable to both develop and sell.
I've had 4 such products on the back burner for several years and will soon be bringing them out of storage and completing my prototypes and testing them for performance. These too will be sold on the internet and the completed products will be offered for sale to companies who specialize in manufacturing and sales of like products.
This is an ongoing project and my goal is to sell the technology rather than manufacturing and distributing of these products.
