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: Read the rest of this entry »

While we were away, we missed the story about the giant mechanical spider in Liverpool.  That spider has come to life, and you can watch the video courtesy of the BBC.

Named La Princesse, she an art project designed to build tourism and boost the economy.  Developed by french company La Machine, she looks amazing.  It looks as though it takes 9 people to pilot her, possibly another running the crane she’s suspended from.  Watch the video and see her reach out and tap an onlooker’s umbrella with one of her legs.
