Dr Gerald Muller is Associate Professor within Engineering and the Environment at the University of Southampton.

My original degree is in structural engineering, but my research has taken me into the fields of low head hydropower, wave energy and more recently thermodynamics. My research is driven by the necessity to create economical and environmentally acceptable solutions for the generation of renewable energy. Quite often my inspiration for research projects comes from the analysis of historic technology which has been forgotten, or which is disregarded today for example because of a perceived lack of efficiency. In my work I mostly use a combination of theoretical and experimental work, the latter with laboratory tests as well as field measurements and prototype scale work.

My main research interest lies in the field of renewable energy, where I am working on low head hydropower and, to a lesser extent on wave energy. In low head hydropower we have developed hydropower converters based on novel concepts, such as the utilisation of hydrostatic pressure differences or the generation of head differences from currents. The principles developed for the utilisation of river and tidal currents were then also be applied to wind energy, using an aerodynamically improved version of the Persian Wind Mill.

The nature of the field has led me to further work in the wider area of renewables and also into thermodynamics at near ambient temperatures. This rather exciting and novel area led to the development of novel concepts for atmospheric steam engines, solar thermal collectors and the characteristics of aerated water flows.

In addition, I am very interested in historic technology for renewable energy, looking at the principles and the performance of historic machines in order to establish whether they have further development potential today, where improved theory, better materials and changed requirements exist.

Examples of my research interests in historic technology include water wheels, buoyancy machines such as Armstrong’s Wave Motor, and the atmospheric steam engine.
