We run a small inventor's workshop and work on various projects there. Our new invention is on the way to being patented. If you are interested in getting involved and sign me a non-disclosure agreement, I will send you the details. The invention is a product that is very simple and inexpensive to produce, that in principle a large part of the world's population can use, that is sustainable, protects the environment and saves the user money. It has the potential to become a real mass product.
