15 Weirdest (or Genius) Patents Ever Granted

  • US4605000: Greenhouse Helmet

Weird when filed in 1986 but seems soon we all be needing one of these helmets. The greenhouse helmet brings nature to you. All you need to do is strap it to your face! A self-enclosed, anti-fog-treated dome sits over the wearer’s head, containing multiple shelves to hold tiny plants inside. As you exhale, the plants soak up the carbon dioxide, supposedly stocking you in return with the purest oxygen. The helmet even has a two-way intercom system, so you can communicate with friends in the not-so-great outdoors.

People have been coming with really strange ideas in the past. Some has been really stupid and some way ahead of their time. Nonetheless, it's important that inventions must continue to be filed despite their being stupid or weird. We never know which of the weird ideas we may be using some day.
