Though not much info is readly available about it on the web, [Joe
Carruth] is trying to build publicity (and venture capital) for his
home-built solar electric generator. At its essence, it is a Stirling
dish system with an adjustable composite mirror surface. This means that
instead of having to rotate the entire contraption in order to follow
the Sun, [Joe] only has to make the mirror segments pivot. A Stirling
steam engine at the tip converts the energy into the movement used to
generate electricity. Solar power plants (or 'farms') that are emerging
are beginning to consider the advantages of using more efficient
Stirling dishes rather than less efficient solar panels. If anyone has
an idea as to how [Joe] can automate sun tracking for the mirrors,
please post it in the comments. A couple more videos on the topic (in
general) are available below:
