Gallery: Shooting Laser Beams in the Sky Could Produce Rain Clouds


Researchers at Switzerland’s University of Geneva have come up with an interesting way of making it rain–shooting lasers high up into the sky. Though the strategy seems like science fiction, the team hopes that the lasers will be able to increase rainfall in areas that need it.

    @iamwho2k – It would just most likely be over the sea.

    And if rain starts being taken away from other areas then we just shoot the lasers there as well.

    This is interesting. But I wonder if it’s possible to prevent rain by spotting the clouds the same way. In some cities in Southern Philippines, it is very common to hit the clouds with light beams (laser?) supposedly to prevent rain esp. when there’s a scheduled festivity, and to protect prawn farms. Is this true? We need rain around here, esp. with the El Niño….

    When I was taking Meteorology 110 way back when we talked about cloud seeding and other man-made methods to make it rain. One of the issues the professor brought up was, paraphrasing, “Sure, you can make it rain here, but then you’ve just taken away the rain from some other part of the map.” Think about it.
