One of my favorite street-use sites is English-Russia. They frequently feature novel ways that Russians create their own technology. The latest example is this clever home-made lawn mower. The site doesn't say much about how it was built, but it seems to created around an electric motor and bicycle parts. About all they say about the machine is: "This particular lawnmower still works and sometimes is used by this Russian man on his “dacha”, the summer wooden cottage where he spends some of his weekends, like many other Russians do."
