My friend Shai Agassi recently announced that he was leaving SAP to do, among other things, a new project on electric cars, starting in Israel. He discussed it a bit at Davos this year, and with many alternative energy transportation efforts, the tricky thing is the fueling/charging infrastructure. Rather than replacing the gas stations that exist today, the idea is to develop a massively distributed charging infrastructure, potentially turning any outlet into a billable filling station by tracking the electricity use and getting the accounting right. Several other electric car projects are also working on distributed power schemes, including using renewable energy for micro-generation. This is, naturally enough, called The Long Tailpipe.
