Richard returns from his boat trip to take part in last week's discussion surrounding Dropbox. Naturally, we end up debating the future of the filesystem and bemoaning the existence of file extensions in 2015. Sparked by Tesla's annoucement last week we spend the rest of the show discussing battery technology, the UK energy crisis, renewable power, and environmentalism (really!).
