Here is an invention that doesn’t claim to change the world but will just give us the pleasure of listening to what goes on inside a tree. As most of us would already know, trees suck up water and nutrients through their natural plumbing system called the xylem tubes. Now Alex Metcalf has designed a system for to actually hear nutrients and water being sucked up by the tree for distribution to its leaves and branches. For this, he has made a sensor that is mounted onto a tiny bugle like listening contraption. When listeners place this contraption on the tree’s bark, they can hear a clicking noise that signifies the water and noise being sucked by the tree. As is with the current trend of everything going green, this contraption too is powered by the very green solar energy. To simplify things, Alex has mounted the Tree Listener onto a tree and has connected it to a few pairs of headphones hanging from the branches. Though this Tree Listening device is currently an oddity, it might very well become the latest fad in the near future. Watch out for it.
