According to an article IBM has designed a dish to concentrate sunlight onto Photovoltaic cells keeping them cool using water. Ahhh, maybe people have a really short memory but this is nothing new. Moving onward….
My preference is sill using a dish to focus sunlight onto a stirling engine which gives and impressive 25-35% efficiency in converting sunlight to heat and electricity with far less effort. Stirling engine also last a fairly long time with little maintenance. What IBM is proposing is good for areas with water or that could use the dish to desalinate water but not in a desert, but stirling engines with concentrating mirrors are perfect.
I’ve now been unemployed coming up to 2 1/2 years and I am finding new freedom in the lack of work. I just have to get use to being so poor.
