“Tesla’s Spirit Radio uses a simple crystal radio circuit connected to a computer sound-in jack to generate spooky sounds from all kinds of electromagnetic sources. As you will see, it creeped the hell out of Tesla himself.”
“My first observations positively terrified me as there was present in them something mysterious, not to say supernatural, and I was alone in my laboratory at night.”
– Nikola Tesla 1901
“The sounds I am listening to every night at first appear to be human voices conversing back and forth in a language I cannot understand. I find it difficult to imagine that I am actually hearing real voices from people not of this planet. There must be a more simple explanation that has so far eluded me.”
– Nikola Tesla 1918
I’m in love with this invention and the appearance of this prototype… It’s an elegant idea, probably too much before its time to really catch on. And now it’s pretty much obsolete as a concept. A newspaper delivered by radio as you sleep, printed in your home. And in 1938!
This invention of a wireless fax, as it were, was credited to W.G. H. Finch and used radio spectrum that was otherwise unused during the late-night hours when most Americans were sleeping. The FCC granted a special license for these transmissions to occur between midnight and 6am, though it would seem that a noisy printing device in your house cranking away in the middle of the night might have been the fatal flaw in their system. It wasn’t exactly a fast delivery either, as the article notes that it takes “a few hours” for the machine to produce your wireless fax newspaper.
This machine makes paper planes, but it also produces delight in certain people. Or is it the human innovation it represents that makes me smile? Hard to look at a machine like this and not see the person who made it.
There was apparently a time in our planet’s history when plants evolved into trees (in order to be able to grow taller while still supporting themselves structurally) but there was no type of fungi yet evolved that could break down the trees when they died. So for a long period trees just piled up. This interesting BBC documentary on decay explains the Carboniferous period. (via reddit)
