Putting a screw thread on the top of a shaving gel can. It allows you to inject fluids to sealed systems that are pressurised without injecting propellant using a bridging tool. With this invention, you can inject water treatment chemicals to a heating system in about a minute. The chemicals save the average home about £80 per year in fuel and extended equipment life. This simple invention was filed for patent by my business partner and I two years ago. It has earned us a lot of money. If used widely in Britain, we will have reduce the UK's greenhouse emissions by 3%. Such a simple idea but it took us two years of trying to come up with it and then it seemed absolutely obvious.
