Peer to peer car sharing company Getaround closed $3.4 million in seed funding. It has a new app that allows users to locate a rental car and unlock it with their smartphone. This is a great example of how mobile can be leveraged in cleantech. Perhaps coincidentally, this round of funding coincided with Sunil Paul’s Cleanweb Hackathon, an event that occurred this past weekend in which developers competed to create an application that would reduce resource consumption. The winner was Team TACO (total cost of ownership), which produced a Google Chrome browser extension that shows users the total cost of owning a product as they shop for it online.
