The "Sliver" technology to which Foolestroupe refers has been acquired by Origin Energy whose main business is selling coal fired electricity. Expect to see this technology going nowhere fast. Meanwhile the SUNBALL http://www.greenandgoldenergy.com.au/ is promising to be commercially released in August. I have got my order in! If it does what it claims then finally Solar Electricity might be a viable alternative. Conventional flat panel solar is a waste of money, you could buy and run a small quiet Honda generator for many years at less cost than buying solar panels and maintaining expensive lead acid batteries.
