GravityLight is one of the very
amazing and mind-blowing inventions I came to know about just a few days ago.
This brand has generated a light lamp, which includes a built-in LED light. But
the surprising thing is that it does not need electricity to work at all.
The force of gravity is what lights up
this lamp. You simply have to hang something weighing around 20 pounds over the
pin that comes with it, and that’s it! You get light without any energy
resource. This invention could totally work wonders in the areas in developing
countries where electricity is still not available!
Another one of such inventions was a
shelf I had seen around somewhere. My niece had gotten this one for herself
that was the first time I saw it. It was no normal shelf, actually, because it
had built-in stairs in it.
