It seems a little like the early days of space exploration. We would get photos that showed something, but we were never quite sure what it was until higher resolution photos arrived later.
A couple of days ago, EarthSpark sent an update. All of the parts are now in Les Anglais and they have assembled one system. They included a photo which appears to be SUNSPOT running an electric pressure cooker.
Hopefully we will get more photos soon, as well as data from both the microgrid powered cooking systems and the off-grid SUNSPOT™ systems.
