The tracking accumulator is a low tech device for concentrating sunlight to do useful work. It could cook food, heat water or air, power a fridge directly, or be used as a mount for solar panels for maximum summer performance.
The accumulator differs from most other solar concentrators in that the target does not move (so stirling engines or a host of other applications can easily be mounted and it works on a timer system. (Like that which is used on telescopes because it is equatorial mount). It is also unusual in that there are 2 half dishes mounted on the frame and 2 focuses. I designed the mechanical mathematician, dripper trackers, clock based trackers and the liquid piston tracker for the tracking solar accumulator project.
The solar design t-square is used to design clam shaped solar cookers for ideal unattended cook times.
This is a humanitarian project. The goal is the provide the maximum sized solar cooker to use all the sunlight for a defined time. So the cook can leave the food and avoid being cooked herself!
Also, the design process must be simple and cheap.
Brian White trained as a lab technician (applied biology) in Ireland, works as a stone mason and invented the pulser pump in the late 1980s which is now being researched in Queens University.
