Innovation expert Doug Hall travels across Canada in search of everyday inventors with exceptional ideas. His mission is to find and mentor Canada's next great inventors, taking them on a journey of a lifetime, from the backyard to the boardroom. In each episode, Hall travels to backyards and basements in search of an inventor with an idea that has real potential. The inventor who impresses him the most will be invited to Eureka! Ranch where their invention will be re-worked, re-tooled and turned into a marketable product that they will ultimately pitch to a big business.

Simcha Blass (November 27, 1897 – July 18, 1982; Hebrew: שמחה בלאס) was a Polish-Israeli engineer and inventor who developed the drip irrigation system with his son Yeshayahu.

In the early 1930s, a farmer drew his attention to a big tree, growing in his backyard “without water”. After digging below the apparently dry surface, Simcha Blass discovered why: water from a leaking coupling was causing a small wet area on the surface, while an expanding onion shaped area of underground water was reaching the roots of this particular tree—and not the others. This sight of tiny drops penetrating the soil causing the growth of a giant tree provided the catalyst for Blass's invention. The drip irrigation concept was born and experiments that followed led Blass to create an irrigation device that used friction and water pressure loss to leak drops of water at regular intervals. Recognizing the high potential of his discovery, he began to look for ways to turn his idea into a product. In the late 1950s, with the advent of modern plastics during and after World War II, he took a major step towards implementing his idea. After leaving government service in 1956 he reopened his private Engineering office and worked with his son Yeshayahu on the drip irrigation idea. The main aspect of the new invention was to release water through larger and longer passageways (rather than tiny holes) by using friction to slow water inside a plastic emitter. Larger passageways prevented the blocking of tiny holes by very small particles. The first experimental system of this type was established in 1959. In the early 1960s, Blass developed and patented this method and the new dripper was the first practical surface drip irrigation emitter. During the years 1960 to 1965 Blass developed the drip-irrigation systems and sold them inside Israel and abroad. In 1965 he contacted Arie Bahir who was in charge of the industry in the kibbutzim in order to find a kibbutz to give him the task of further developing this new enterprise. Out of some suggestions, Blass chose kibbutz Hazerim in the Negev.
