Modular habitation and medical facilities

As a multi-skilled engineer with over 40 years of experience and flair for design and problem solving I have been considering the use of shipping containers for some time now, over the past six months have developed a system of units that can be fitted out in an almost limitless number of ways with a bias towards humanitarian and disaster relief. The modules can be either “stand alone” or part...

Perfect Mason Mate

I have invented a new tool for the construction of brick walls. This new tool enables error free construction of brick walls even by laymen. This tool eliminates the use of a mason line and plum b-bob. The carbon footprint of a building constructed thus is reduced as the cement mortar saving is 50% when compared to the conventional methods. See the tool in action in the video below and...
