    Not quite the same as the fog lights described here, but… As I-64 crosses Afton Mountain west of Charlottesville, VA there are a series of lights along the side of the road that turn on when conditions are bad. They were first installed in the mid1970s and have been updated in recent years.

    I’m amazed at how often the inventions MI published in the “inventions wanted” column had been invented years, or decades, before they appeared. Seed tape, for example, was patented at least as early as 1915 (patent 1,160,279). Patent 1,669,773 issued in 1928 for a heated bathtub just as described. Fog control by heaters had been tried succesfully at airfields during WWII – although it’s questionable whether or not the expenditure of energy could have been justified in peacetime along roads. And so on…

    That seed tape sounds like a good idea. It would make laying out the garden significantly quicker.

    An electric bathtub. What a spark(l)ing idea!

    Zeppflyer , the seed tape is a product you can buy today, just google seed tape.

    JW: But they do more or less exist – lots of folks get electrically powered “spa baths” these days. Not to mention the “smart toilets.”

    If the user held the hammer at the end of the handle it would drive a nail faster.

    Heated bathtubs have been around for a while, and Chuck Woolery sells motorized lures on his home page.
