A type of home energy production, this is similar to standard wind turbines in that it produces electricity from wind, but it can be mounted very low to the ground and spins no matter what direction the wind is blowing (even up). This is pretty cool if it works as well as it seems.

I second the commentor on the article who suggested that these could be mounted on lampposts all over the city to generate power.

I have always said the best defense against theft is to have a lousy car. Now I might want a nice car someday, but there must be a way to make it at least look bad…. Well here's a good example: stickers that make your car look rusted.

It would be simple enough to scrape away paint and let it rust for real or bang in the metal here and there, but real damage affects resale and could end up causing need of repairs. This solution is far more elegant.
